executive committee of the directing council HEALTH ORGANIZATION .e worMng party of the regional committee HEALTH ORGANIZATION 113th Meeting Washington, D.C. 27June-1 July1994 t Provisional Agenda Item 4.5 CEl13/13 (Eag.) 17 May 1994 ORIGINAL: ENGLISH INTERNATIONAL BASIC SAFETY STANDARDS FOR PROTECTION AGAINST IONIZING RADIATION AND FOR SAFETY OF RADIATION SOURCES The technical document International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources ('BSS) is presented to Member States to encourage them to consider and use it, at their discretion, in future radiation protection regulations. ·' : In order to cope with the expanding uses of radiation sources and nuclear practices, and in view of the particular character of the radiation risks, radiation protection has developed during the last few decades a unique and elaborate system of concepts, principles and techniques for the prevention and control of radiological risks. The scientific and conceptual bases for this system are established by the International Commission on Radiological Protection (ICRP) in the form of recommendations that are · regularly updated and adapted to new scientific knowledge. In its 1991 publication the ICRP adopted a different radiation risk model and a revised dosimetry of the Hiroshima and Nagasaki atomic explosions. The main consequence is that cancer mortality due to radiation is considered to be three to four times higher than previously thought, leading to the need for a reduction on dose limits both for occupationally exposed persons and for the general public. Another "new" feature in the 1991 ICRP publication was the development of the concept of "potential exposures," i.e., those that could occur in accidental situations requiring special safety measures for their prevention. Because the ICRP recommendations are deliberately drafted in general and scientific terms, sufficient scope for interpretation and application is left to the users of the recommendations, particularly national authorities. There is, therefore, a continuing need for a conversion of the ICRP guidance into terms which are sufficiently practical CEl13/13 Page 2 (Eng.) and straightforward to facilitate their transfer into regulatory and operational practices at the national level. The need for international harmonization was recognized in 1982 when the previous edition of the BSS was jointly sponsored by the International Atomic Energy Agency (IAEA), the International Labor Organization (ILO), the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD), and the World Health Organization (WHO). In 1990, an Interagency Committee of Radiation Safety (IACRS) was constituted as a forum for consultation on collaboration in radiation safety matters between international organizations. This Committee is comprised of the Commission of European Communities (CEC), the Food and Agriculture Organization (FAO), the IAEA, the ILO, the NEA/OECD, the Pan American Health Organization (PAHO)--which joined them in 1991--the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and WHO. The ICRP, the International Electrotechnical Commission (IEC), the International Radiation Protection Association (IRPA) and the International Organization for Standardization (ISO) have international observer status on the IACRS. The first effort of the IACRS was to prepare this current version of the BSS, which is jointly sponsored by FAO, IAEA, ILO, NEA/OECD, PAHO, and WHO. PAHO is not a newcomer to this field. It initiated radiological health activities in the 1950s, promoting public health aspects of radiation and providing fellowships for the training of physicians and other professionals in radiation medicine. In 1960 a Radiation Protection Unit was established at the regional level. Today the radiological health program covers the uses of ionizing and non-ionizing radiation in health services, such as diagnostic imaging, radiation therapy and nuclear medicine, and it emphasizes radiation protection and safety, including preparedness training and assistance in the case of radiological emergencies. PAHO is interested in sponsoring the document in order to ensure that the Standards reflect the needs of its Member States, where most radiation applications involve not large sources such as nuclear power plants but small sources mostly in the field of medicine. It is thought that the document could be used by most governments of Latin America and the Caribbean that lack the necessary radiation safety infrastructure or need to update their legislation/regulations. Furthermore, the specific guidance of the document on accidental situations can be used in case of radiological emergencies, such as those that have occurred in this Region in recent times. An accident in Argentina in 1984 resulted in the death of a worker. There have been two serious accidents caused by medical radioactive sources: one in 1984 in Ciudad Jufirez, Mexico (where more than 4,000 people were exposed and recovery costs were US$34 million), and another in 1987 in Goiania, Brazil (where over 100,000 people had to be monitored, four people died from radiation sickness, and decontamination costs alone surpassed US$20 million). In m CE113/13 Page 3 (Eng.) E1 Salvador in 1989, an industrial irradiator accident resulted in the death of one worker and amputation of both legs of another (the total cost of the accident was to US$20 million). The last fatal accident in the Region occurred in November 1992 in the United States of America (Indiana, Pennsylvania) when a patient being treated for anal carcinoma with a high dose rate bmchytherapy remote aftefioading device, died after receiving an overdose of radiation. Ninety-four persons were evaluated for possible overexposure. The financial consequences axe still being evaluated. The main purpose of the BSS is to give guidance to national authorities on the establishment of regulations and operational criteria adapted to local situations. The applicative requirements and guidelines of the BSS were given the character of "standards" so that national authorities could use them directly as a regulatory basis for the protection of workers and members of the public, or simply as reference material. Members States, in fact, are not formally committed to bring their legislation into conformity with the Standards, which are not intended to replace national laws and regulations. Another function of the BSS is to provide technical guidance to the management bodies with responsibilities for radiation protection in their own operations, as well as to the professional operators in radiation protection. The Standards cover protection for all radiation sources that can be controlled. These include natural radiation sources, activities in the nuclear fuel cycle, the medical applications of radiation, and sources used in industry, research, agriculture. The provisions of the Standards address the exposure of workers and members of the public and patients exposed to medical radiation sources. The "Medical Exposures" section has been considerably expanded from previous versions, having been written mainly by a PAHO staff member. The Standards contain general and specific requirements which in some cases are completed by detailed numerical guidance in terms of limits, reference levels, intervention levels, and exemption levels. The degree of development of this numerical guidance differs by type of exposure, depending on the degree of international consensus that was possible to achieve. ' · To obtain international consensus, successive drafts have undergone elaborate review procedures. (See attached list for meetings held.) The organizations represented in the Joint Secretariat approached the revision of the various internal drafts from different perspectives: for example, WHO and PAHO focused on radiation protection in the medical uses of radiation; ILO was mindful of the reactions of employer and worker groups; FAO was particularly interested in intervention measures relating to food and agriculture, and IAEA and NEA/OECD, in the practical implications of nuclear energy and nuclear applications. CE113/13 (Eng.) Page 4 The process of issuing the Standards is reaching its f'mal stage. Consensus on the final draft of the BSS was, in fact, reached by the experts of Member States present at the Technical Committee Meeting held at the IAEA Headquarters in Vienna in December 1993, attended by 152 representatives of 48 countries and 11 international organizations. The document is now being submitted for adoption to the Governing Bodies of the six sponsoring organi?ations. It is expected it will be published in 1995. Annexes CEl13/13 (Eng.)

A'FrA_ RF_.S'I_CTED TO GOV/271S, APRIL 1.994 DISTIL, ORIGXNAL:F_.NG_ FOREWORD (to the interim edition) by the Director General These International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Ra&ation Sources mark the culmination of efforts that have continued over the past several decades towards the harmonization of radiation protection and safety standards internationally The Standards are jointly sponsored by the Food and Agriculture Organization of the Umted Nations (FAO), the International Atomic Energy Agency (IAEA), the International Labour Organisation (ILO), the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA), the Pan American Health Organization (PAHO) and the World Health Organization (WHO) (the "Sponsoring Organlzations"). The unprecedented international effort to draft and review the Standards involved hundreds of experts fi.om the Member States of the Sponsoring Organizations and from specialized organizations The meeting of the Techmcal Committee that endorsed the Standards in December 1993 was attended by 127 experts from 52 countries and 11 organizations. The IAEA's Board of Governors approved the Standards on its ... Meeting on June ... 1994, and the IAEA is herewith issuing them in an interim publication (in English only). Once the Standards have been formally adopted or acknowledged by the other Sponsoring Organizations, they will be issued in the IAEA Safety Series as a final publication in Arabic, Chinese, English, French, Russian and Spanish. ATI'A_ TO GOV/2715, APRIL 1994 RF_,..q'I'RI_-I_I) DISTR., ORIGINAL.ENGLISH PREFACE Background Although all the Sponsoring Orgamzations are revolved m the international harmonization of radiation protection and safety, the IAEA is speclficallyauthorized under the terms of its Statute to estabhsh standards of safety for the protection of health and the minimiz_lon of danger to life, in consultation with the United Nations and the specialized agencies concerned. Not surprisingly, therefore, m the family of international governmental organizations, the first endeavour to establish ra&atlon safety standards was made al the IAEA. The Board of Governors of the IAEA first approved radiation protection and safety measures in March 1960 _,when it was stated that "The Agency's basic safety standards.., will be based, to the extent possible, on the recommendations of the International Commission on Radiological Protection CICRP)". The Board first approved basic safety standards in June 1962; they were published by the IAEA as Safety Series No. 92. A revised version was published in 19673 A third revision was published by the IAEA as the 1982 Edition of Safety Series No. 94;this Editaon was jointly sponsored by the IAEA, the ILO, the OECD/NEA and the WHO. In 1990, an important step towards international harmonization ofradlation safety took place, an Inter-Agency Committee on Radiation Safety (IACILS) was constituted as a forum for consultation on and collaboration in radiation safety matters between international organizations s. The IACRS initially comprised the Commission of the European Communities (CEC), the Council for Mutual Economic Assistance (CMEA) (now defunct), the FAO, the IAEA, the ILO, the OECD/NEA, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and the WHO. The PAHO jomed subsequently. The ICRP, the International CommLssion on Radlological Units and Measurements (ICRU), the International Electrotecimical Commission (IEC), the International Radiation Protection Association (IRPA) and the International Organization for Standardization (ISO) have observer status on the IACRS. The objective of the [ACRS is to promote consistency and co-ordination of policies with respect to the following areas of common interest' applyingradlatlon safety principles, criteria and standards and translatmg them into regulatory terms; co-ordinating research and development; advancing education and training, promoting widespread information exchange, facilitating the Iransfer of technology and know-how; and providing radiation safety services. Within this framework, the Sponsoring Organizations established a Joint Secretariat (the "Joint Secretariat") for the preparation of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources, the "Standards", contained in this publication. The Joint Secretariat was co-ordinated by the IAEA. The Standards supersede the previous basic international standards and reflect knowledge gamed subsequently and developments in radiation protection and safety and related fields. 2 1 INTERNATIONAL ATOMIC ENERGY AGENCY, The Agency's Health and Safety Measures, INFCIRC/18, IAEA, Vienna (1960), The Agency's Safety Standards and Measures, INFCIRC/18/Rev t, IAEA, V'Denna(1976). 2 INTERNATIONAL ATOMIC ENERGY AGENCY, Basic Safety Standards for Radlabon Protection, Safety Series No 9, IAEA, Vienna (1962) 3 INTERNATIONAL ATOMIC ENERGY AGENCY, Basic Safety Standards for Rad_fion Safety Senes No 9, IAEA.

The ICRP is a non-governmental scientffic organization founded m 1928 to establish basic principles and recommendations for radiation protection; the most recent recommendanons of the ICRP were issued in 19916. Moreover, tn relation to safety, the Standards take account of the principles recommended by the International Nuclear Safety Advisory Group (INSAG) which, under the auspices of the IAEA, has been elaborating nuclear safety concepts since 1985, such as its Basic Safety Principles for Nuclear Power Plants7; many of these principles are relevant to radiation sources and installations other than nuclear installations The quanuties and units used in the Standards are primarily those recommended by the International Commission on Radiation Units and Measurements (ICRU), a sister organization of ICRP. The Standards are published in the IAEA Safety Series. This series of publications encompasses Safety Fundamentals, Safety Standards, Safety Guides and Safety Practices relating to nuclear safety and radaation protectmn, including radioactive waste management. 8 The IAEA Safety Series includes other related international standards, such as the Nuclear Safety Standards 0qUSS) for nuclear power plants, the Regulations for the Safe Transport of Radioactive Material, and the forthcoming Radioactive Waste Management Standards (RADWASS). The other organizatmns of the Joint Secretariat have also produced codes and guides in their respective spheres of activity. Notably, the ILO has issued a code of practice for the radiation protection of workers as well as other relevant publications, the PAHO and the WHO have issued a number of documents relating to the safety of workers and patients in medical applications of radiation; the FAO and the WHO have established, through the Codex Alimentarius Commission, guideline levels for radioactive substances in foodstuffs moving in international trade; and the OECD/NEA has published documents on specific topics relating to radiation safety. Objective The purpose of the Standards is to establish basic requirements for protection against the nsks associated with exposure to ionizing radiation (hereinafter called radiation) and for the safety of radmnon sources that may deliver such exposure. The Standards have been developed from widely accepted radiation protection and safety principles, such as those published in the Annals of the ICRP and the IAEA Safety Series. They are intended to ensure the safety of all types of radiation sources and, in doing so, to complement standards already developed for large and complex radiation sources, such as nuclear reactors and large nuclear waste management and disposal facilities. For these sources, more specific standard, such as those issued by the IAEA, are typically needed to achieve acceptable levels of safety. As these more specific standards are generally consistent with the Standards, in complying with them, such more complex installations will also generally comply with the Standards. The Standards are limited to specifying basic radiation safety requirements, with some guidance on how to applythem. General guidance on applying some of the requirements is available in the publicatmns of the Sponsoring Organizations and additional guidance will be developed as needed in the light of experience gained in the application of the Standards. 6 INTERNATIONAl.

The requirements have the force that is derived from the statutory provisions of the Sponsoring Organizations. They do not entail any obligation for States to bring their legislauon into conformity with them, nor are they intended to replace the provisions of natmnal laws or regulations, or the standards in force They are aimed rather to serve as a practical guide for public authorities and services, employers and workers, specialized radiation protection bodies, enterprises and safety and health committees The requirements lay down basic principles and indicate the differera aspects that should be covered by an effective radiation protection programme. They are not intended to be applied as they stand in all countries and regions, but should be interpreted to take account of local situations, technical resources, the scale of installations and other factors which will determine the potential for application. The Standards cover a broad range of practices and sources that give rise to or could give rise to exposure to radiation, and many of the requirements have therefore been drafted in general terms. It follows that any given requirement may have to be fulfilled differently for different types of practice and source, according to the nature of the operations and the potential for exposures Not all the requtrements willapply to every practice or to every source, and it is up to the appropriate Regulatory Authonty to specify which of the requirements are applicable in each case. The scope of the Standards is limited to the protection ofhurnan beings only; it is consldered that standards of protection that are adequate for this purpose willalso ensure that no other species is threatened as a population, even if inchviduals of the species may be harmed. Moreover, the Standards apply only to ionufing radiation, namely gamma and X rays and alpha, beta and other particles that can reduce wnizauon They do not apply to non-ionizing radiation; neither do they apply to the control of other non-radiological aspects of health and safety. The Standards recognize that radmtion is only one of many sources of nsk m life, and that the risks associated with radiation should not only be weighed against its benefits but also viewed in perspective with risks from other sources. Structure The Standards comprise a Preamble, the Principal Requirements, Appendices and Annexes The Preamble states the aims and the bases of the Standards, explains the underlying principles and philosophy, and describes appropriate governmental arrangements for applying the Standards The Principal Requirements specify what is imperative in order to fulfilthe aims of the Standards. Consequential Detailed Requirements, subsidiary to the Principal Requirements, are specified in the Appendices. Quantitative standards and guidance are provided in the Annexes. A Glossary, the list of experts who contributed to the drafting and review process, and the hst of the representatives of countries and organizauons in the Technical Committee which endorsed the Standards in December 1993 are also included. The Sponsoring Organizations are briefly described on the back inside cover.

Ionizing radiation and radtoactive substances are natural and permanent features of the environment, and thus the risks associated with radlabon in all its forms can only be restricted, not eliminated entirely Additionally, the use of man-made redtation ts widespread. Sources of iomz/ng radiation are essential to modem health care. disposable medtcal suppltes stenltzed by Intense radiation have been central to combat/ng dtsease; radiology is a vitaldtagnostic too/; and radtotherapy ts commonly part of the treatment of mahgnancies The use of nuclear energy and applicabons of Es by-products, £e. ionizing radtatlon and radioactive substances, cont/nue to increase around the world Nuclear techmques are m grow/ng use for industry, agnculture, medicine and many fields of research, benefitmg hundreds of millions ofpeople and giv/ng employmentto milltons ofpeople in the related occupations Irradtabon is used around the world to preserve foodstuffs and reduce wastage, and stenhzation techmques have been used to eradicate dtsease carry/ng insects and pests Industnal radtography is in routine use, for example to exam/ne welds and detect cracks and help prevent the failure of engineered structures. The acceptance by society of risks assoctated with radtation is condrttonalon the benefits to be ga/ned from the use made of radiation. Nonetheless, the risks must be restricted and protected against by the application of radtabon safety standards. The Standards provide a destrable mtemabonal consensus for this purpose The Standards draw upon informabon derived from extensive research and development work by scientific and eng/neenng orgamzations, at national and intemattonal levels, on the health effects of radlabon and techniques for the safe design and operabon of radiation sources; and upon experience m many countries in the use of radiation and nuclear techmques The United Nabons Scientific Commrttee on the Effects of Atomic Radtation (UNSCEAR), a body set up by the Unrted Nabons in 1955, compiles, assesses and dtsseminates informatton on the health effects of radiabon and on levels of radiation exposure due to different sources, this Information was taken into account in develop/ng the Standards. Purely scientific considerattons, however, are only part of the basis for decistons on protection and safety, and the Standards implicitlyencourage deciston makers to make valuejudgements about the relative importance of risks of dFrferentk/nds and about the balanc/ng of risks and benefits. RADIATION EFFECTS Exposure to radiation can cause detrimental health effects At large doses, radiation effects such as nausea, reddening of the skin or, m severe cases, more acute syndromes are chntcally expressed in exposed individuals wrthm a short period of time after the exposure, such effects are called 'determintsbc" because they are certain to occur if the dose exceeds a threshold level Radiation exposure can also induce effects such as malignancies whtchare expressed after a latency penod and may be eptdemiologlcally detectable in a population; thts inductton is assumed to take place over the enttre range of doses without a threshold level Heredrtary effects due to radiabon exposure have been stabsbcally detected in other mammalian poputabonsand are presumed to occur 9 A'VFACHMENT TO GOVf271S, APRIL 1994 RESTRICTED DISTR., ORIGINAL'ENGLISH in human populabonsalso. These ep/demiologtcally detectable effects -malignanctes and hereditary effects - are termed 'stochasbc" effects because of their random nature Determtnistlc effects due to radtation exposure are the result of drfferentprocesses, mainly cell kilhng and delayed cell divtston,whtchcan, ff extensive enough, impair the funcbonof the exposed tissue The seventy of a particular determmtstic effect in an exposed tnd_wdua/tncreases wrththe dose above the threshold for the occurrence of the effect Stochastic effects may ensue if an irradmted cell is modifed rather than killed Modified cells may, after a prolonged delay, develop into a cancer. The body's repair and defence mechamsms make thts a verytmprobable outcome at small doses, nevertheless, there is no evidence of a threshold dose below which cancer cannot result. The probability of occurrence of cancer ts htgher for higher doses,but the seventy of any cancer that may resultfrom trradtabonis independent of the dose. Also, if a germ cell whose funcbon is to transmit genetic mformabon to progeny Is damaged owing to radtation exposure, it rs concen_ablethat hereditary effects of vanous types may develop m the descendants of the exposed person The likelthood of stochastic effects rs presumed to be proporbonal to the dose racen,ed - also without a dose threshold In additton to the aforementioned health effects,other health effects may occurin infantsdue to exposure of the embryo or foetus to radtabon. These effects include a greater likelihood of leukaemia and, for exposure above various threshold dose values dunng certain penods of pregnancy, severe mental retardation and congenital mafformabons. Since a small likelihood of occurrence of stochastic effects at even the lowest doses Is assumed, the Standards cover the enbra range of doses with the arm of constraining any radtabon detriment that may arise The many aspects of the concept of radtatton detriment make it undestrable to select any single quanbty to represent it The Standards are therefore based on a concept of detriment as recommended by the ICRP, which for stochasbc effects Includesthe followmg quantrtles' the probabl#ty of fatal cancer attributable to radtation exposure; the wetghted probabt#ty of mcumng a non-fatal cancer;,the wetghted probab#rty of severe hereditary effects, and the length of lifettme lost if the harm occurs PRACTICES AND INTERVENTIONS Human activities that add radtation exposure to that whtch people normally recur due to background radtatlon, or that increase the Itkellhood of their incumng exposure, are termed 'pracbces' m the Standards. The human activlbes that seek to reduce the exisbng radiatton exposure, or the extsttng likelthood of incumng exposure which ts not part of a controlled pracbce, are termed 'mtervenbons'. The Standards apply to both the commencement and the contmuabon of pracbces that involve or could involve radlabon exposure, and also to extstmg, de facto s_tuabons In whtch exposure or its hkelihood can be reduced or prevented by means of some intervenbon. For a practice, provisions for radlabon protecbon and safety can be made before its commencement, and the assoctated radmtion exposures and their likelihood can be restricted from the outset In the case of intervenbon, the circumstancesgivtng rise to exposure or the Itkeithood of exposure already exist, and their reduction can only be achieved by means of remedtal or protectn,e actions The pracbces for which the Standards are intended to prowde the basts for protecbon against radiation _ncludethe followtng' activittes involvingthe producbon of radiatton sources, the use of radiation and radioacbve substances in medlctne, research, industry, agricultureand teaching; the generation of electricity by nuclear power, including the entire cycle of related activrbes from the mining and processing of radtoactlve ores to the operation of nuclear reactors and fuel cycle fac#ibes and the management of radtoactive wastes, and activibes such as the underground mining of coal and of phosphabc and other mtnerals that may enhance exposure to naturally occumng radtoacbve substances Situattons that may requtre intervention include' chronic exposure to naturally occurring sources of radiatJonsuch as radon m dwellings, and to radioactive rastdues from past activities and 10 ATTACItMENTTO GOV/2715,APRIL1994 RERI_L"T_ DISTR.,ORIGINAL-.F..3IGLI_ events; and emergency exposure situabons such as might result from accidents or from deficiencies in existing installat/ons. TYPES OF RADIATION EXPOSURE * !t is virtually certain that some radiation exposures will result from the performance of pracbces and that the/r magnitudes will be predictable, albeit with some degree of uncertainty such expected exposures are referred to in the Standards as 'normal exposures'. Also, exposure scenarios can be envisaged for which there is a potential for exposure, but no certainty that an exposure will tn fact occur, such unexpected but feasible exposures are termed 'potential exposures' Potential exposures can become actual exposures if the unexpected situation does occur, for example as a consequence of equipment failure, design or operating errors, or unforeseen changes tn environmental conditions, e.g. at a disposal site for radioactive waste. If the occurrence of such events can be foreseen, the probability of their occurrence and the resulting radiation exposure can be estimated. The means specified tn the Standards for controlling normal exposures is the restriction of the doses delivered The primary means for controlling potential exposures is by good design of installabons, equipment and operating procedures; this ts intended to limit the probability of occurrence of events that could lead to unplanned exposures and to restrict the magnitudes of exposures that could result if such events were to occur. The relevant radiation exposures covered by the Standards encompass the exposures, both normal and potential, of workers pursuing their occupations, of patients in diagnosis or treatment, and of members of the public who may be affected by a practice, or by an intervent/on. For intervenbon situations the exposure can be chronic or, in some cases of emergencies, temporary Thus exposures are divided into: 'occupabonatexposures' which are incurred at work and pnnctpally as a result of work, 'medical exposures' which are principally exposures of pabents in diagnosis or treatment, and 'public exposures' which comprise all other exposures, potential exposures and emergency and chronic exposures The Standards ara intended to cover all people who may be exposed to rad/ation, including those in future generabons who could be affected by present practices or interventions. BASIC PRINCIPLES . The pnnciples of radiation protection and safety on which the Standards are based are those developed by the ICRP and by INSAG The detailed formulation of these principles can be found tn the publlcabons of the ICRP and INSAG and they cannot easily be paraphrased w_thoutlosing their essence. However, a brief - although simplified, summary of the principles is as follows' a practice that entails or that could entail exposure to radiation should only be adopted if it y_elds sufficient benefit to the exposed individuals or to society to outweigh the radiation detriment tt causes or could cause (i.e., the practice must be justified)s, individual doses due to the combmabon of all relevant practices should not exceed specified dose limits; radiation sources and installations should be provided with the best available protection and safety measures under the prevailing circumstances, so that the magnitudes and likelihood of exposures and the numbers of individuals exposed are as Iow as reasonably achievable, economic and social factors being taken into account, and the doses they deliver and the risk they entail should be constrained O.e. protection and safety should be opbm/zed), radiation exposure due to sources of radiation that are not part of a practice should be reduced by intervention when th/s Isjustified, and the intervention measures should be opttmtzed, the legal person authorized to engage in a pracbce involwng a source of radlabon should bear the primary responsibil/ty for protection and safety, a safety culture should be inculcated that governs the attitudes s Usually,compliancewitfithe pnncipleof jus'dficabon is adequatelydemons13'ated znrespectof a type of actwtty bythe existenceor the la_nng downof regula_ons specrfically concerningthe type of ac_v_y 11 ATTACHMENT TO GOV/2715, APRIL 1994 _C'TED DISTR., ORIGINAL'ENGLISH and behaviour in relation to protection and safety of all individuals and organrzabons dealing w/th sources of radiation; in-depth defensive measures should be incorporated into the design and operabng procedures for radratlon sources to compensate forpotenbaf failures in protection or safety measures;and protection and safety should be ensured by sound management and engmeenng, quality assurance, training and qualificabon of personnel, comprehensive safety assessments and attention to lessons learned from experience and research w QUANTI77ES AND UNITS Although most of the requrrements of the Standards are qual/tatrve, the Standards also establrshquantitative limits, and gurdance levels For these purposes, the marn physrcal quant/ties used m the Standards are the rate of nuclear transformabon of radlonuclldes (the act/vYe')and the energy absorbed by a unit mass of a substance from the radratron to which it Is exposed (the absorbed dose). The unit of activity ls the reciprocal second, representing the number of nuclear transformations (or drsintegrabons) per second, whrch is termed the becquerel (Bq) The umt of absorbed dose Is the joule per kilogram, termed the gray (Gy) The absorbed dose Is the bastc physical dosrmetnc quantity of the Standards However, # is not entirely satisfactory for radmbon protection purposes because effecbveness m damaging human bssue differs for different types of ionizing radlat_on Consequently, the absorbed dose/n bssues is multiplred by a radmbon weighting factor to take account of the effectiveness of the g/ven type of radlatron m reducing health effects; the resulting quantity rs termed the equivalent dose The quantrtyeqwvalent dose is used when individual organs or tissues are irradiated, but the I_kelihood of mjudous stochastic effects due to a given equivalent dose differs for different organs and bssues. Consequently, the equivalent dose to each organ and bssue ts multiplied by a bssue weighting factor to take account of the organ's radiosensitivity The sum total of such weighted equivalent doses for all exposed bssues in an mdiwdual is termed the effective dose. The unit of equivalent dose and effective dose is the same as the unit of absorbed dose, namely joule per kilogram, but the term slevert (Sv) Is used in order to avord confusion with unit of absorbed dose When radlonuclJdes are taken into the body, the resulting dose _sreceived throughout the period of time dunng which they remain in the body The committed dose is the total dose delivered dunng this period of time, and is calculated as a specified bme integral of the rate of recerpt of the dose Any relevant dose restncbon is applred to the committed dose from the retake The total rmpact of the radiation exposure due to a given practice or source depends on the number of indiwduals exposed and on the doses they receive The collecbve dose, defined as the summabon of the products of the mean dose in the various groups of exposed people and the number of individuals in each group, may therefore be used to characterize the radlabon Impact of a practice or source The unit of collecbve dose is the man-slevert (man.Sv) GOVERNMENTAL REGULATION The Standards are intended to place requirements on those legal persons authorized to conduct pracbces that cause radlation exposure or to _ntervene in order to reduce exrstmg exposures; these persons have the primary responsibiln'yfor applying the Standards Governments, however, have responsibility for therr enforcement, generally through a system that includes a Regulatory Authority, and for planning and talong acbons tn different circumstances In addition, governments generally provide for certain essenbal rad_abonsafety serwces and for interventions that exceed or that complement the capabilities of the legal persons authorized to conduct practices The Standards are based therefore on the presumpbon that a nabonal infrastructure is m place enabling the Government to discharge its respons_bilibesfor radlabon protecbon and safety 12 ATTACHMENT TO GOV/2715, APRIl, 1994 RESTRICTED DISTR., ORIGINAL:ENGLISH NATIONAL INFRASTRUCTURES . Essential parts of a nabonal infrastructure are: legislation and regulations, a Regulatory Authority empowered to authorize and inspect regulated activitres and to enforce the legtslabon and regulatrons; sufficrent resources, and adequate numbers of trained personnel The infrastructures must also provrde ways and means of addressing societal concerns whrch extend beyond the legal responsrbil/tresof the persons authorized to conduct practices involving sources of redratron For example, national authoritres ensure that appropriate arrangements are made for detecting any buildup of radroacbve substances m the general envrronment, for drsposmg ofradroactn/e wastes and for prepanng for interventions, partrcularly during emergencies that could result _nexposure of the general public They also need to provide for the control of sources of rad;abon for which no other organizabon has responslbi;/ty, such as natural sources and radioactn/e resldues from past practices National infrastructures must provide for adequate arrangements to be made by the responsible persons for the educabon and training of specialists in radrabon protection and safety, as well as for the exchange of mforrnabon among specrallsts. A related respons;bilrty Is to set up appropnate means of reforming the public, /ts representatives and the inforrnabonmedia about the health and safety aspects of acbv/tles revolvingexposure to radtatron and about regulatory processes This provides rnformation to facil/tate the pol/tlcal process of setting nabonal pnoritres and allocating resources for protection and safety and also helps to make the regulatory process more read#y understandable. National infrastructures must also provide facil/ties and serwces that are essenbal for radration protection and safety, but are beyond the capabilitres requrred of the persons who are authorized to conduct practices Such facilitresand services include those needed for mtervenbon, personal dosrmetry and environmental monitonng, and for calrbrabon and rntercompanson of radlabon measunng equrpment Services could include the prowsron of central regtstnes for occupabonal exposure records and the provrslon of information on equipment reliability The provision of such services at the national level does not detract from the ultimateresponsrbil/ty for radlabon safety borne by the persons authonzed to conduct the pracbces. THE REGULA TORY AUTHORITY Full and proper implementation of the Standards requires that a Regulatory Authonty be established by government to regulate the introduction and conduct of any practice involwng sources of radrabon Such a Regulatory Authority must be prowded w/th sufficrentpowers and resources for effective regulabon and should be independent of any government departments and agencies that are responsible for the promobon and development of the practtces being regulated The Regulatory Authority must also be independent of registrants, licensees and the designers and constructors of the radiation sources used rn practices The effective separation of responsibil/tres between the funcbons of the Regulatory Authority and those of any other party is to be made clear so that the regulators retain their independence of judgement and declsron as safety author/ties , The Standards are worded on the assumpbon that a single Regulatory Authonty is responsrble for all aspects of radiation protectton and safety in a country. In some countries, however, regulatory responsrbilityfor different practices or different aspects of radlabon safety may be drwded between different authorities. Consequently, the term Regulatory Authority rs generally used in the Standards to mean the relevant Regulatory Authority for the particular source or aspect of radlabon safety in question. Regardless of the division of regulatory respons_b#ittes, the government must ensure that all aspects are covered; for example, it must ensure that a specrfic body rs assigned responsibility for the regulatory surveillance of protecbon and safety measures for patlents and of qual#y assurance measures for equipment and techniques for medical uses of radlabon The type of regulatory system adopted in a country will depend on the size, complex/ty and safety implicabons of the regulated practices and sources, as well as on the regulatory trad/tlons in 13 ATTACHMENT TO GOV/2715, APRIL 1994 RF,,.qTRICTED DISTR., ORIGINAL:ENGLISH the country. The mechanism for carryfngout regulatory duties may vary, with some authorities being completely self-sufficient and others delegating some inspection, assessment or other duties to varfous governmental, public or pm/ate agencies A Regulatory Authority may also be serf-sufficient in specialist expertise or it may consult expert advisers and advisory committees. The general functions of the Regulatory Authority include the following the assessment of applications for permission to conduct practices that entail or could entail exposure to radJatlon,the authorization of such practices and of the sourcesassociated with them, subject to certain specrfied conditions; the conduct of penodlc inspections to verify compliance with the condrtlons, and the enforcement of any necessary actionsto ensure compliance with the regulations and standards For these purposes, mechanisms are needed for notlficabon, reglstratton and licensing of the sources w_th_npractices, with provision for the exclusionor exemption of sources or practices from regulatory requirements under certain conditions. Provision is also needed for the surveillance, monrtonng, review, verification and inspection of sources and for ensunng that adequate plans exist for dealing with radJation accidents and carrying out emergency interventions The effectiveness of radiation protection and safety measures for each authorized practice and the total potential impact of authorized practices need to be assessed The powers of the inspectors of the Regulatory Authority must be well defined and consistency of enforcement must be maintained, w/th prowsion for appeal by those responsible for sources Directives to both inspectors and regulated persons must be clear The Regulatory Authority may need to prowde guidance on how certain regulatory requirements are to be fulfilled for vanous practices, for example in regulatoryguideline documents An attitude of openness and cooperation must be fostered between regulated persons and inspectors, which includes fac#itatmg access by inspectors to premises and to information An additional responsibility of the Regulatory Authority !s to require all parties revolved to develop a safety culture that includes individual and collective commitment to safety on the part of workers, management and regulators, accountability of all individuals for protecbon and safety, including individuals at senior management level, and measures to encourage a questioning and learning att/rude and to discourage complacency w/th respect to safety. Due account needs to be taken by both the Regulatory Authority and the regulated persons of general expenence and of new developmentsm radiation protection and the safety of sources. 14 ATF&CHMENT TO GOV/2715, APRIL 1994 _CTED DISTR., ORIGINAL:ENGLISH EDITORIAL - NOTE 1.

II.4 RADIATION PROTECTION II.4.1 Justification of Practices REQUIREMENTS (43) No practice or source within a practice should be authorized unless the practice produces sufficient benefit to the exposed individuals or to society to offset the radiation harm that it might cause; that is: unless the practice is justified, taking into account social, economic and other relevant factors. (44) Detailed requirements are given in Appendix 2. for the justification of practices involving medical exposures (45) Except for justified practices involving medical exposures, the following practices are deemed to be not justified whenever they would result in an increase, by deliberate addition or activation, of the activity of radioactive substances in the associated commodities or products: (a) practices involving food, beverages, cosmetics or any other commodity or product intended for ingestion, inhalation or percutaneous intake by, or application to, a human being; and (b) practices involving the frivolous use of radiation or radioactive substances in commodities or products such as toys and personal jeweUery or adornments.

EXPOSURES: SAFETY OF SOURCES RESPONSIBILITIES (182) Registrants and licensees shall ensure the safety of the sources, including installations, for which they are responsible and shall: (a) apply the Principal Requirements specified in the Standards; and Co) apply as appropriate the Detailed Requirements set out in Appendix IV. (183) Guidance on the practical aspects of the safety of nuclear installations and of radtoactive waste management facilities is given in publications within the NUSS Programme and RADWASS Programme in the IAEA Safety Series as well as in documents of the Sponsoring Organizations. This section specifies requirements on the practical aspects of the safety of sources and practices other than nuclear installations and radioactive waste management facihties, which are intended to support the Principal Requirements of the Standards. 2. SAFETY ASSESSMENT (184) Registrants and licensees shall conduct a safety assessment, either generic or specific for the source for which they are responsible, as required under the Principal Requirements. Generic safety assessments are usually sufficient for types of source with a high degree of uniformity in design. Specific safety assessment is usually required in other cases but the specific safety assessment need not reconsider those aspects covered by a generic safety assessment, if such an assessment has been conducted for the source. (185) The safety assessment shall include, as appropriate, a systematic critical review of: (a) the nature and magnitude of potential exposures and the likelihood of their occurrence; Co) the limits and technical conditions for operation of the source; (c) the ways in which structures, systems, components and procedures related to protection or safety might fail, singly or in combination, or otherwise lead to potential exposures, and the consequences of such failures; (d) the ways in which changes in the environment could affect protection or safety; (e) the ways in which operating procedures related to protection or safety might be erroneous, and the consequences of such errors; and (f) the protection and safety implications of any proposed modifications. (186) The registrant assessment: (a) or licensee shall, as appropriate, take into account in the safety factors which could precipitate a substantial release of any radioactive substance and the measures available to prevent or control such a release, and the maximum activtty of any 65 ATTACHMENT TO GOV/2715, APRIL 1994 RESTRICTED DISTR., ORIGINAL: ENGLISH (b) (c) (d) radioactive substance which, in the event of a major failure of the containment, might be released to the atmosphere; factors which could precipitate a smaller but continuing release of any radioactive substance and the measures available to prevent or control such a release; factors which could give rise to the unintended operation of any radiation beam and the measures available to prevent, identify and control such occurrences; the extent to which redundant and diverse safety features, being independent of each other so that failure of one does not result in failure of any other, are appropriate in order to restrict the probability and magnitude of potential exposures. (187) The safety assessment shall be documented and, if appropriate, independently reviewed within the relevant quality assurance programme. Additional reviews shall be performed as necessary for ensuring that the technical specifications or conditions of use continue to be met whenever: (a) Co) (c) significant modifications to a source or its associated plant or its operating or maintenance procedures are envisioned; operating experience, or other information about accidents, failures, errors or other events that could lead to potential exposures indicates that the current assessment might be invalid; and any significant changes in activities, or any relevant changes in guidelines or standards, are envisaged or have been made. (188) If as a result of a safety assessment, or for any other reason, opporttmities for improving the protection or safety measures associated with a source within a practice seem to be available and desirable, any consequential modifications shall be made cautiously and only after a favourable assessment of all the implications for protection and safety; and if such improvements cannot all be implemented, or not all at once, they shall be prioritized so as to result in optimum improvements in protection or safety. 3. REQUIREMENTS 3.1 Responsibilities FOR DESIGN (189) Registrants and licensees, in specific co-operation with suppliers, shall ensure that the following responsibilities be discharged, if applicable: (a) to provide a well designed and constructed source that: (i) provides for protection and saJ_ty in compliance with the Standards; (ii) meets engineering, performance and functional specifications; and (iii) meets quality norms commensurate with the protection and safety significance of components and systems; Co) to ensure that sources be tested to demonstrate compliance with the appropriate specifications; and 66 A'IFi'ACHMENT TO GOV/2715, APRIL 1994 RESTRICTED DISTR., ORIGINAL: ENGLISH (c) to make available information in a major world language acceptable to the user concerning the proper installation and use of the source and its associated risks. (190) In addition, and where applicable, registrants and licensees shall make suitable arrangements with suppliers of sources: (a) to establish and maintain mechanisms for suppliers to obtain information from the registrants and licensees or other users on the use, maintenance, operating experience, dismantling and disposal of sources, and in any particular normal or abnormal operating conditions that may be important for the protection of individuals or the safety of the source; Co) to establish and maintain a mechanism to feed back to registrants and licensees information that may have implications for protection or saJkty affecting other registrants or licensees, or that may have implications for future improvements in protection or safety in the design of their products. 3.2 Prevention of Accidents and Mitigation of their Consequences (191) Systems and components of sources that are related to protection or safety shall be designed, constructed, operated and maintained so as to prevent accidents, as far as possible, and in general to restrict to levels which are as low as reasonably achievable, social and economical considerations being taken into account, the magnitude and likelihood of exposure of workersand members of the public. ' ' (192) The registrant or licensee of any source or practice shall make suitable arrangements: (a) to prevent, as far as possible, any accident, occurrence or incident that could reasonably be foreseen in connection with the source or practice; (b) to limit the consequences of any accident, occurrence or incident that does occur; (c) to provide workerswith the information, training, and equipment necessary to restrict their potential exposure; (d) to ensure that there be adequate procedures for the control of the source and of any potential accident that could reasonably be foreseen; (e) to ensure that safety significant systems, components and equipment can be inspected and tested regularly for any degradation that could lead to abnormal conditions or inadequate performance; (f) to ensure that maintenance, inspection and testing appropriate to the preservation of the protection and safety provisions can be carried out without undue occupational exposure; (g) to provide, wherever appropriate, automatic systems for safely shutting off or reducing radiation output from sources in the event that operating conditions exceed the operating ranges; (h) to ensure that abnormal operating conditions that could significantly affect protection or safety be detected by monitoring systems that respond quickly enough to allow for timely corrective action to be taken; and (i) to ensure that all relevant safety documentation be available in local languages. 67 AI'FACHMENT TO GOV/2715, APRIL 1994 RESTRICTED DISTR., ORIGINAL: ENGUSH (193) As required in Appendix V, if the safety assessment indicates that there is a reasonable remaining likelihood for an accident affecting either workers or members of the public, the registrant or licensee shall prepare an emergency plan. This plan is to be designed to secure as far as possible the protection and safety of anyone who may be affected by the accident. As part of this plan the registrant or licensee should ensure that: (a) any worker under the registrant's or hcensee's control who may be involved in or affected by arrangements in the plan has been suitably and sufficiently trained and if appropriate issued with suitable protective equipment and dosimeters; and Co) if appropriate, rehearsals of the arrangements in the plans be carried out at suitable intervals. 3.3 Location and Siting of Sources (194) Account shall be taken in choosing the location for any small source within installations and facilities such as hospitals and manufacturing plants of: (a) factors that could affect the safety and security of the source; Co) factors that could affect the occupational exposure and public exposure caused by the source, including features such as ventilation, shielding and distance from occupied areas; and (c) the feasibility in engineering design of taking into account the foregoing factors. (195) The selection of a site for a source that holds a large inventory of radioactive substances and has the potential for releases of large amounts of such radioactive substances shall take into account any features that might affect the radiation safety of the source and features that might be affected by the source, and the feasibility of offsite intervention, including carrying out emergency plans and protective actions. 4. REQUIREMENTS 4.1 Responsibilities FOR OPERATIONS (196) Registrants and licensees may delegate certain tasks involved with the operation of sources under their responsibility but shall retain the responsibility for ensuring that all operations are conducted in a manner consistem with the requirements of the Standards. (197) 68 Where applicable, registrants and licensees should: (a) establish clear lines of responsibility and accountability for protection and safety of the sources throughout their operational lifetime, and establish protection and safety organizations as appropriate; Co) for any source under their control that has the potential to give rise to exposures at levels greater than those specified by the Regulatory Authority as needing a specific safety assessment as required by Appendix IV, carry out and keep up to date that special assessment; ATTACHMENT TO GOV/2715, APRIL 1994 RESTRICTED DISTR., ORIGINAL: ENGLISH (c) (d) (e) (f) (g) 4.2 assess the likely consequences of any potential exposures, their magnitude and probability of occurrence, and the number of persons who may be affected by them; have in place operating procedures that are subject to periodic review and updating under an adequate quality assurance programme; establish procedures for reporting and learning from accidents, occurrences and incidents; establish arrangements for the periodic review of the overall effectiveness of the protection and safety measures; ensure that adequate maintenance, testing, inspection and servicing be carried out as needed so that sources remain capable of meeting their design requirements for protection and safety throughout their lifetime. Source Accountability (198) Registrants and licensees shall maintain an accountability system that includes records of: (a) the location and description of each source for which they are responsible; and Co) the activity and form of each radioactive substance for which they are responsible. 4.3 Investigations and Follow-up (199) Registrants and licensees shall conduct formal investigations as specified by the RegulatoryAuthority if: (a) a quantity or operating parameter related to protection or saJktyexceeds an investigation level or is outside the stipulated range of operating conditions; or Co) any equipment failure, accident, error, mishap or other unusual event or circumstance occurs which has the potential for causing a quantity to exceed any relevant limit or operating restriction. (200) The investigation shall be conducted as soon as possible after the event and a written report produced on its cause, with a verification or determination of any doses received or committed and recommendations for preventing the recurrence of similar events. ' (201) A summary report of any formal investigation relating to events prescribed by the Regulatory Authority, including exposures greater than a dose limit, shall be communicated to the Regulatory Authority as soon as possible and to other parties as appropriate. 4.4 Accident Management Preparedness (202) Registrants and licensees shall be prepared to take any necessary action for responding to and correcting any reasonably foreseeable operating mishap or accident that could involve a source. 69 ATTACHMENT TO GOV/2715, APRIL 1994 RESTRICTED DISTR., ORIGINAL: ENGUSH (203) For sources with the potential for abnormal exposures where there is a possibility for taking action to control or otherwise influence the course of an accident and to mitigate its consequences, registrants and licensees shall: (a) prepare in advance guidance on accident management in their premises that takes into account the expected response of the protection and safety features of the source to accidents; (b) make available equipment, instrumentation and diagnostic aids that may be needed to control the course and consequences of accidents involving sources; and (c) train operating and emergencypersonnel and periodically retrain them in the procedures to be followed if an accident occurs. 4.5 Feedback of Operating Experience (204) Registrants and licensees shall ensure that information on both normal and abnormal operations significant to protectionor safety be disseminated or made available, as appropriate, to the RegulatoryAuthorityand other relevant parties, as specified by the Regulatory Authority. This information would cover, for example, doses associated with given activities, maintenance data, descriptions of events and corrective actions. 5. QUALITY ASSURANCE (205) Registrants and licensees shall be responsible for establishing the quality assurance programme required by the principal requirements &these Standards, and the nature and extent of the quality assurance programme shall be commensurable with the magnitude and the likelihood of the potential exposures fi.om the sources for which they are responsible. (206) 70 The quality assurance programme shall provide for: (a) planned and systematic actions aimed at providing adequate confidence that the specified design and operational requirements related to protection and safety are satisfied, including provisions for feedback of operational experience; (b) a framework for the analysis of tasks, developmem of methods, establishmem of norms and identification of necessary skills for the design and operation of the source; and (c) validation of designs and supply and use of materials, of manufacturing, inspection and testing methods, and of operating and other procedures.

EXPOSURE V SITUATIONS RESPONSIBILITIES (207) It is presumed that the State will have determined in advance the allocation of responsibilities for the management of interventions in emergency exposure situations between the Regulatory Authority, national and local Intervening Organzzations and licensees or registrants. 2. EMERGENCY PLANS (208) Emergency plans shall be prepared which specify how the responsibilities for the management of interventions will be discharged on the site, off the site and across national boundaries, as appropriate, in separate but interconnecting plans. (209) The appropriate responsible authorities shall ensure that: (a) emergency plans be prepared and approved for any practice or source which could give rise to a need for emergency intervention; Co) Intervening Organizations be involved in the preparation of emergency plans, as appropriate; (c) the content, features and extent of emergency plans take into account the results of any accident analysis and any lessons learned from operating experience and from accidents that have occurred with sources of a similar type; (d) emergency plans be periodically reviewed and updated; (e) provision be made for training personnel involved in implementing emergency plans and the plans be rehearsed at suitable intervals in conjunction with designated authorities; and (f) prior information be provided to members of the public who could reasonably be expected to be affected by an accident. (210) Emergency plans shall include, as appropriate: allocation of responsibilities for notifying the relevant authorities and for initiating intervention; identification of the various operating and other conditions of the source which could lead to the need for intervention; interventionlevels, based on a consideration of the guidelines in Annex V, for the relevant protective actions and the scope of their application, with account taken of the possible degrees of severity of accidents or emergencies that could occur; procedures, including communication arrangements, for contacting any relevant Intervening Organization and for obtaining assistance from fh-efighting, medical, police and other relevant organizations; a description of the methodology and instrumentation for assessing the accident and its consequences on and off the site; (a) Co) (c) (d) (e) 71 ATYA_ _CI'ED TO GOV/2715, APRIL 1994 DISTR., ORIGINAL:ENGLISH (f) a description of the public information arrangements in the evem of an accident; and (g) the criteria for term;.nating each protective action. (211) Registrants and licensees shall ensure that adequate provision be made for generating adequate information promptly and communicating it to the responsible authorities, for: (a) the early prediction or assessment of the extent and significance of any accidental discharge of radioactive substances to the environment; (b) rapid and continuous assessment of the accident as it proceeds; and (c) determining the need for protective actions. (212) On-site emergency plans shall be implemented by registrants and licensees. (213) Off-site emergency plans and any transboundary plan shall be implemented by the Intervening Organizations. 3. INWERVENTION FOR EMERGENCY EXPOSURE SITUATIONS 3.1 General (214) Interventionin emergency exposure situations shall be carried out on the basis of mterventionlevels and action levels. Interventionlevels are expressed in terms of the dose that is expected to be averted over time by a specific protective action associated with the intervention, and action levels in terms of the acnvity concentration of radionuclides in, for example, foodstuffs, water, and crops. (215) Intervention levels and action levels shall be optimiT,ed for the relevant protecnve actions but they should not allow that certain levels of doses, for which mtervention will almost always be justified, be exceeded. The values of intervention levels included in emergencyplans shall be used as initial criteria for implementing protective acttons, but may be modified to take into account the prevailing circumstances and their likely evolution. 3.2 Justification of Intervention (216) Protective actions will be almost certain to be justified if the projected dose, rather than the averted dose, or the dose rate to any individual is otherwise likely to lead to serious injury. In such circumstances, any decision not to take protective action on an urgent basis will have to be justified. The levels of dose which could lead to such injury are given in Annex IV. 3.3 Optimization of Protective Actions: Intervention Levels and Actions Levels 3.3.1 Intervention and Action Levels for Immediate Protective Actions (217) Decisions to take immediate protective action shall be made in the light of circumstances prevailing at the time of an accident and be based on the expectation of 72 A'I_A_ _l..-L_o TO GOV/2715, APRIL 1994 DISTR., ORIGINAL:ENGLISH a release, if this is feasible, of radioactive substances to the environment, rather than delayed pending measurements to confirm the release. In addition to these protective actions, there are others, such as personal decontamination or elementary forms of respiratory protection, that may be invoked in special cases but for which intervention levels have not been established. . (218) Intervention levels for immediate protective actions, including sheltering, evacuation and iodine prophylaxis, shall be specified in emergency plans, taking into account the guidance given in Annex V, and intervention shall be considered for any population in which the avertable dose is expected to exceed the interventionlevels. (219) Action levels for the withdrawal and substitution of specific supplies of food and drinking water shall be specified in emergency plans as appropriate. (220) If there is no shortage of food and there are no other compelling social or economic factors, the action levels for the withdrawal and substitution of specific supplies of food and drinking water shall be based on the guidance given in Annex V and shall comply with the recommendations of the FAO-WHO Codex Alimentarius Commission for the international trade of food that has been contaminated with radionuclides. 36 The action levels shall be applied to food as consumed, and to dried or concentrated food after dilution or reconstitution. (221) In certain circumstances, if food is scarce or there are other serious social or economic considerations, higher optimized action levels for food and drinking water would be expected to be used. However, decisions to take action above the action levels specified in Annex V shall be subject to the process of justification of interventionand optimization of the action levels. (222) Classes of food, such as spices, that are consumed in small quantities (e.g. less than 10 kg per person per year), which represent a very small fraction of the total diet and would increase individual exposure very little, may have action levels ten times higher than those for major foodstuffs. 3.3 Intervention and Action Levels for Longer Term Protective Actions (223) Agricultural, hydrological and other technical or industrial protective actions shall be considered following contamination of land or water after an accident, taking into account the guidance of FAO and IAEA on radiation accidents and agricultural countermeasures. 37 36 Joint FAO/WHO Food Standards Programme, Codex Ahmerrtanus Commission, 1 (lg91); Sectmn 6 1, Levels for Radlonuchdes 37 Codex Nimentanus, Volume Food and Agriculture Organization of the United Nations, Radiation Accidents and Agricultural Countermezsures, FAO/IAEA, Vienna (1993). 73 ATTACHMENT TO GOV/2715, APRIL 1994 RF...qTRIC-lED DISTR., ORIGINAL: ENGLISH (224) The international trading of food that has been contaminated with radionuclides shall be subject to the recommendations of the FA)-WHO Codex Alimentaxius Commission38 specified in Annex V. (225) Interventionlevels for temporary relocation and return of exposed persons shall be specified in emergency plans taking into account the guidance given in Annex V. (226) The interveningorganizationshall keep people who axe temporarily relocated informed of their likely time of return to their homes and about the safeguarding of their property. (227) if: Consideration shall be given to permanent resettlement of exposed persons (a) the duration of temporary relocation is expected to exceed an agreed period; or Co) permanent resettlement is justified by virtue of the dose which could be averted. Guidance on generic interventionlevels for permanent resettlement is given in Annex V. (228) before 4. Appropriate consultations with people potentially affected shall be made initiating programmes of permanent resettlement. ASSESSMENT AND MONITORING AFTER ACCIDENTS (229) All reasonable steps shall be taken to assess exposure incurred by membersof the public as a consequence of an accident, and the results of the assessments shall be made publicly available. (230) The assessments shall be based on the best available information, and shall be promptly updated in the light of any information that would produce substantially more accurate results. (231) Comprehensive records shall be maintained of assessments and their updates, and of monitoring results for the workers,public, and the environment. 5.

When undertaking interventionunder these circumstances, all reasonable efforts shall be made to keep doses to workers below twice the maximum single year dose limit, except for life-saving actions, in which every effort shall be made to keep doses below ten times the maximum single year dose limit in order to avoid deterministiceffects on health. In addition, workers undertaking actions in which their doses may approach or exceed ten times the maximum single year dose limit shall do so only when the benefits to others clearly outweigh their own risk.

(11.2) Subject to the requirements set forth in paragraph (28), for exposure to radon at or above an average annual concentration of 1000 Bq.m'3 45of air, of radon progeny in a workplace, the dose limits for occupational exposure and the relevant requirements of Appendix I shall apply. (11.3) The dose limits are not relevant for the control of potential exposures. (11.4) The dose limits are not relevant for decisions on whether and how to undertake an intervention, but workers undertaking an intervention shall be subject to the relevant requirements of Appendix V. Occupational Exposure Dose Limits (11.5) The occupational exposure of any worker shall be so controlled that the following limits are not exceeded: (a) an effective dose of 20 mSv per year averaged over five consecutive years46; Co) an effective dose of 50 rosy in any single year; (c) an equivalent dose to the lens of the eye of 150 mSv in a year; and 45 The Intemataonal Commission on Radaological Protection has recommended that the actton levels for ocoupatlonal exposure to radon can fall m the range 500.1500 Bq m 'a.

(II.6) For apprentices of 16 to 18 years of age who are training for employment involving exposure to radiation and for students of age 16 to 18 who are required to use sources in the course of their studies, the occupational exposure shall be so controlled that the following limits are not exceeded: (a) an effective dose of 6 mSv in a year; Co) an equivalent dose to the lens of the eye of 50 mSv in a year; and (c) an equivalent dose to the extremities or the skin4° of 150 mSv in a year. Special Circumstances (11.7) When, in special circumqances 48, a temporary change in the dose limitation requirements is approved pursuant to Appendix I: (a) the dose averaging period mentioned in (II.5)(a) may exceptionally be up to 10 consecutive years as specified by the RegulatoryAuthority,and the effectivedose for any workershall not exceed 20 mSv per year averaged over this period and shall not exceed 50 mSv in any single year, and the circumstances shall be reviewed when the dose accumulated by any worker since the start of the emended averaging period reaches 100 mSv; or Co) the temporary change in the dose limitation shall be as specified by the RegulatoryAuthoritybut shall not exceed 50 mSv in any year and the period of the temporary change shall not exceed 5 years. Public Exposure Dose Limits (11.8) Exposure of membersof the public attributable to practices shall not exceed the following limits which shall apply to the estimated average doses to the relevant critzcal groups: (a) an effective dose of 1 rosy in a year; Co) in special cireum._anees, an efj_ctive dose of up to 5 mSv in a single year provided that the average dose over five consecutive years does not exceed 1 rosy per year; (c) an equivalent dose to the lens of the eye of 15 mSv in a year; and (d) an equivalent dose to the skin of 50 mSv in a year. Dose Limitation for Comforters of Patients and Visitors to Patients 47 The equivalent dose limits for the skln apply to the average dose over 1cra2 ,n the most h_ghly ,rrad_ated area of the skin Skin dose also contributes to the effectJve dose, where thBs ¢ontnbubon ,s the average dose to the enbre skin mulbphed by the bssue weighting factor for the skin. 48 See Appendix I 98 Provaslons for 'alternative employment' may be relevant ATTACHMENT TO GOV/27'15,APRIL 1994 RESTRICTEDDISTR., ORIGINAL: ENGUSH - (I1.9) The dose limits set out in this part shall not apply to comforters of patients, i.e., to individuals knowingly exposed while voluntarily helping (other than in their employment or occupation) in the care, support and comfort, including visiting, of patients undergoing medical diagnosis or treamaent. However, the exposure of any such comforter of patients shall be constrained so that it is unlikely that his or her exposure will exceed 5 mSv during the period of a patient's diagnostic examination or lxeatment. The dose to children visiting patients who have ingested radioactive materials should be constrained to less than 1 mSv per treatment. Verification of Compliance With Dose Limits (II.10) The dose limits specified in Annex II apply to the sum of the relevant doses from external exposure in the specified period and the relevant committed doses from mtakes in the same period; the period for calculating the committed dose shall normally be 50 years for intakes by adults and to age 70 years for intakes by children. (1I. 11) For the purpose of demonstrating compliance with dose limits, the sum of the personal dose equivalent from external exposure to penetrating radtation in the specified period and the committed equivalent dose or committed ef_ctive dose, as appropriate, from intakes of radioactive substances in the same period shall be taken into account. (II.12) Compliance with the foregoing requirements for application of the dose limits on ef/kctive dose shall be determined by either of the following methods: (a) by comparing the total effectzve dose with the relevant dose limtt, where the total ef2'kctivedose E r is calculated according to the following formula: where H/d) is the personal dose equivalent from penetrating radiation 49during the year; h(g)j,_, and h(g)j,.aare the committed effective dose per ingested or inhaled unit intake for radionuclide j by the group of age g; and/J,,.s and /_._ respectively are the intake via ingestion or inhalation of radionuclide j during the same period; or Co) by satisfying the following condition: 49 The use of the ICRUoperatJonalquantity,personaldoseequn,aJent, Hp(d), for this purpose ,sappropnate for all radiations except neurons _nthe energy range 1 eV to 30 kev In srmatJonswhere neutrons_nth_senergy range contribute a major _a_on of the ef[ec'tn_dose, add_onal reformation may be necessaryto cleterrnmethe relat,onsh_pbetweenthe value of Hp(10) and the corresponding effecbvedose 99 ATrACHMENI' TO GOV/2715, APRIL 1994 RESTRICTEDDISTR.,ORIGINAL: ENGUSH where DL is the relevant limit on effective dose, and /j =g.Land /j,,_L respectively are the annual limit of intake via ingestion or via inhalation of radionuclide j (i.e. the intake, through the relevant route of radionuclide j that leads to the relevant limit on effective dose); or (c) by any other approved method.

(V.2) The values of avertable dose specified in intervention levels refer to the average over suitably chosen samples of the population, not to the most exposed (i.e., critical groups of) individuals. However, projected doses to critical groups of individuals should be kept within the dose levels specified in Annex IV. (¥.3) General principles governing the selection of intervention levels for radiological emergencies have been recommended by the ICRP 54 that also indicate the broad range of values within which such levels can be expected to fall. (V.4) The IAEA has developed values resulting from the generic application of these principles to the more common forms of protective actions,ss (V.5) Site specific intervention levels may be higher or in some cases lower than these generic optimized values owing to consideration of site or situation-specific factors. These may include, among others, the presence of special populations (e.g. hospital patients, residents of old-age homes or prisoners), the existence of hazardous weather conditions or compounding ha?arts (e.g. earthquakes or hazardous chemicals), and special problems associated with transport or due to high density populations and other unique characteristics of the site or the accidental release. (V.6) With these factors taken into consideration, the values specified hereinafter can be taken as starting points for the judgements required for decisions to select intervention levels for emergency exposure situations: A. URGENT PROTECTIVE PROPHYLAXIS ACTIONS: SHELTERING, EVACUATION, IODINE (V.7.) The generic optimized intervention level for sheltering is 10mSvofavertable dose, for a period of no more than 2 days.

Higher interventzon levels may be appropriate in situations where evacuation would be difficult, e.g. for large population groups or if there is inadequate transport. (V.9) The generic optimized intervention value for iodine prophylaxis is 100 mGy of avertable committed absorbed dose to the thyroid due to radioiodine. B.

If the dose accumulated in a month is not expected to fall below thi._ level within a year or two, permanent resettlement with no expectation of return to homes should be considered.

' Dose constraint: A prospective upper bound on the individual dose which is used in the optimiTation of protection and safety for sources. For occupational exposures, dose constraint is a source related value of individual dose used to limit the range of options considered in the process of optimization. For public exposure, the dose constraint is an upper bound on the annual doses that membersof thepublic should receive from the planned operation of any controlled source. The exposureto which the dose constraint applies is the annual dose to any critical group, smnmed over all exposurepathways, arising 167 ATTACHMENT TO GOV/2715, APRIL 1994 RESTRICTEDDISTR.,ORIGINALENGLISH from the predicted operation of the controlled source. The constraint for each source should ensure that the sum of doses to the critical group from all controlled sources remains within the dose limit.
