posted where they may be seen both by employees and by the general public.
4.0
Radioactive Spill Procedures
The procedures given below must be followed if there is a spill of radioactive material:
1. Notify all persons in the area that a spill has occurred. Prevent all possibly contaminated persons from
leaving the area. If personnel are contaminated, refer to Procedure for Decontamination of Personnel
below.
2. Notify the Radiation Safety Officer.
a) If the magnitude of the spill is large (volume or activity), secure the area and wait for instructions
from the RSO.
b) If necessary, call the Public Safety Department (780-5211 or 911 on a campus telephone) for
assistance in securing the area.
3. For small spills or when directed by the Radiation Safety Officer:
a) Put on gloves and prevent the spread of contamination by covering the spill with absorbent
paper. Use enough paper to absorb all the liquid.
b) Place masking tape around the spill area.
c) Carefully fold the absorbent paper with the clean side out and place in a plastic bag.
9
d) Wash the contaminated area with detergent. Wash the area just inside the tape first and work
toward the center. This will limit the spread of contamination.
e) Once the area is thoroughly washed, perform a wipe test on a 10 x 10 cm area (100 cm2) within
the tape. Wipe this area with an alcohol swipe and place in a vial. Place another alcohol swipe
in a vial to use as a background swipe.
f) The wipe test results must be recorded in DPM/100 cm2 (disintegrations per minute per 100
cm2). Record this value in the spill log.
g) For I-125, I-131, I-123, In-111, Co-57, Co-58 and P-32 the wipe test results must be less than 20
DPM/100 cm2 for an unrestricted area, or less than 200 DPM/100 cm2 for a restricted area. For
all other isotopes, the wipe test results must be less than 20 DPM/100 cm2 for an unrestricted
area, or less than 200 DPM/100 cm2 for a restricted area. If the measured wipe test activity
exceeds the limits, the area must undergo further decontamination and be retested. Contact the
Radiation Safety Officer if you have any questions.
h) Remove the tape and dispose of any contaminated absorbent paper, gloves, and other material in
the same manner as radioactive waste.
i) Complete a radioactive spill report form and contact the Radiation Safety Officer (see Appendix
A, Forms).
4. If necessary the Radiation Safety Officer will notify staff, USM administration and external authorities.
5.0
Procedure for Decontamination of Personnel
If personnel are contaminated with radioactive material, the procedures given below must be followed:
1. Injured Personnel: Persons who are injured as well as contaminated, and who require immediate
medical attention, should receive medical care without regard for the contamination. The University
policy for response to persons injured within the facility should be followed. Persons caring for the
injured, contaminated person should use universal precautions to minimize the effects and spread of
contamination. When the injured person is stable, an evaluation of the contamination should be made
and decontamination efforts initiated.
2. Contaminated Skin
a) Go immediately to a sink and wash the contaminated area gently with cool water, using a mild
soap solution or a commercial cleanser such as Radiacwash. Do not use warm or hot water since
that will cause the pores in the skin to open. Wash gently for five to ten minutes. Avoid
abrasion of the skin. Abrasion of the skin increases the difficulty of removing the radioactive
material.
b) Emergency eye washes are available and can be used to flush the eyes thoroughly. The RSO
must be informed immediately if radioactive material contaminates an individual's eyes.
c) Survey the contaminated area with Geiger Counter or NaI detector.
d) Continue washing and surveying the area until you observe background radiation levels.
e) Record all actions taken on a Radioactive Spill Report form (see Appendix A,). The completed
form should be given to the University Environmental Health and Safety office.
3. Contaminated Clothing
a) Any clothing that is contaminated should be removed and placed in a plastic bag. Label this bag
with your initials, the name of the radioactive material spilled, the location of the radioactive
10
material on the clothing, and approximately how much radioactive material was spilled on the
clothing.
b) Keep this bag in a secure location and notify University Environmental Health and Safety office
for decontamination or disposal.
6.0
Evaluation of Users and Uses of Radioactive Materials
Proposals to add new users and/or new uses of radioactive material must be submitted on specified forms and
will be evaluated by the Radiation Safety Committee. The action of the committee will be noted in the minutes,
and a letter will be sent to the applicant indicating approval or disapproval of the proposal. If the proposal is
denied, an explanation of the reasons for denial will be provided.
The following subjects will be evaluated:
1. Types of isotopes, their activities and the forms desired.
2. Adequacy of the facilities and equipment to maintain exposures to radiation workers, other workers and
the general public below regulatory limits and ALARA principles. Included in this area are the

3. Previous training and experience of persons who will be responsible for the use of material.
4. Training that will be provided to radiation workers in the areas of use and to other personnel who may
come into contact with radioactive material.
5. When a proposal is approved, a numbered permit will be issued specifying the types of isotopes
allowed; the activities; the locations of use; the approved users; any restrictions; and the beginning and
expiration dates of the permit. Permits will normally be issued for a period of two years, renewable
upon reapplication and satisfactory performance.
6. The Maine State Radiation Control Program will have the sole authority to add or delete an
Authorized User (AU).
7. Once a new user is approved by the RSC and the State, an amendment request will be sent to the
Maine State Radiation Control Program for amendment of the Limited Scope license.

Training for Radiation Workers
All employees who may come into contact with radioactive materials in the course of their work will be trained
in radiation safety at a level commensurate with their risk. The training will be given upon initial employment
and whenever methods or procedures change or are modified. The type of training will vary depending on the
level of exposure to employees.
1. Ancillary Employees
Ancillary employees are employees who don’t actually work with radioactive materials or radiation
producing equipment but work in the vicinity of where this type of work is conducted. Examples of
13
Ancillary employees are individuals who work with environmental services, police, engineering,
materials management and others who only have occasional contact with areas where radioactive
materials are used or stored.
The purpose of the training is to familiarize personnel with radiation, radioactive materials, or radiation
producing instruments, the hazards of exposure to radiation, and the safeguards recommended to prevent
or minimize exposure at this university. The University Environmental Health and Safety office and
RSO will provided this instruction.
Periodic refresher training for these groups will be conducted by the University Environmental Health
and Safety office.
2. Radiation Workers
In addition to the training received by ancillary personnel, radiation workers receive additional training
specific to the materials used and tasks performed. Particular emphasis is placed on recognition of
hazards and methods for individual employees to protect themselves, other workers and the general
public.
Radiation workers also receive hands-on training prior to actually working with radioactive materials or
radiation producing equipment or whenever there is a significant change in the laboratory protocols
specific to the research being conducted. The training is provided by the authorized user or the
authorized user’s designee.
All training is documented. Documentation includes the names of individuals receiving training, date
and location of training, topics copied and signature of trainer. Records of training are maintained by
the University Environmental Health and Safety office. The authorized user also maintains a copy of
this documentation which is available for inspection in or near the laboratory where the work takes
place.

Safe Use of Radioactive Materials
1. Adherence to regulations
The University of Southern Maine will conduct its operations involving radioactive materials in
accordance with statements made in license applications, provisions of licenses granted by the State of
Maine and regulations promulgated by the State of Maine and other appropriate regulatory bodies.
2. Personal radiation safety: Each person handling radioactive material shall be responsible for conducting
work in a manner that will keep radiation exposure to a minimum, for the worker, fellow workers,
patients and the general public. The radiation protection rules given below must be followed:
a) Wear laboratory coats or other protective clothing at all times in areas where radioactive
materials are used.
b) Wear disposable gloves at all times while handling radioactive materials. While wearing gloves,
do not touch objects such as the telephone, doorknobs, etc. Gloves should be changed when you
leave the immediate local area of radioactivity.
c) All radioactive solutions and materials must be properly labeled.
d) Never pipette radioactive materials by mouth.
14
e) Prevent the spread of contamination by handling all radioactive materials on a disposable,
absorbent pad.
f) Do not eat, drink, smoke, or apply cosmetics in any area where radioactive material is used or
stored.
g) Do not store food, drink, or personal effects in areas where radioactive material is used or stored.
h) Wear personal radiation monitors (PRM) at all times while in areas where radioactive materials
are used or stored. These devices should be worn as prescribed by the Radiation Safety Officer.
When not being worn to monitor occupational exposures, PRM should be stored in the work
place in a low background area.
i) Dispose of radioactive waste only in designated, labeled, and properly shielded receptacles. Any
glassware or other object that has been in contact with radioactive materials shall be disposed of
with other radioactive waste or decontaminated.
j) Notify the University Environmental Health and Safety office (X 5406) if any of the following
occurs.
i. Spill of radioactive material
ii. Known or suspected external or internal over-exposure to radiation
iii. Known or suspected contamination of work areas
10.0
Radiation Exposure of the Fertile Woman and the Embryo/Fetus
1. Introduction
The University of Southern Maine recognizes the fact that female radiation workers who are pregnant or
who plan to become pregnant in the future are concerned about the effects of radiation on their fetus.
For this reason, it is felt that a statement of policy concerning the duties and continued employment of
such employees is advisable. The purpose of this policy is to provide maximum protection to the fetus
without placing undue burdens on fellow employees.
2. Estimate of Risk
The National Council of Radiation Protection (NCRP) reviewed the studies and literature concerning
hazards to the fetus from radiation exposure, and published its findings as NCRP Report #53 (Review of
NCRP Radiation Dose Limit for Embryo and Fetus in occupationally-exposed Women – March, 1977).
Similar findings were reported by the National Academy of Science and the Committee on the
Biological Effects of Ionizing Radiations (BEIR) in the 1990 Beir V Report.
The NCRP found that there is no direct evidence of increased birth defects or childhood leukemia or other
cancers at the exposure levels normally encountered in university laboratory facilities. Some estimates
may be obtained by means of extrapolation of high-dose data, or from animal studies, but it must be
realized that such extrapolations are subject to considerable uncertainty. Using “worst-case” data obtained
from several studies, the NCRP found the following:
a) Birth Defects: The natural incidence of birth defects is about 40,000 cases per 1,000,000
pregnancies. If all 1,000,000 women were given a dose of 0.5 rem to the fetus, an additional 10
cases would be expected (for a total of 40,010).
b) Childhood Leukemia: The natural incidence of childhood leukemia (during the first 10 years of
life) is about 1,000 cases per 1,000,000 pregnancies. If all 1,000,000 women were given a dose of
0.5 rem to the fetus, an additional 35 cases would be expected (for a total of 1,035).
15
It should be emphasized that these numbers represent “worst-case” estimates, and the actual risk is
probably much less.
It should also be noted that these estimates are based on a dose of 0.5 rem to the fetus. Because of
attenuation due to the tissue between the mother’s skin and the fetus, the surface dose required to deliver
0.5 rem to the fetus will be higher. In the case of laboratory personnel, the surface dose would have to be
on the order of 2-3 rem. The surface dose is what is recorded by the employee’s personal dosimeter.
3. Current Exposure Levels
Due to improvements in radiation safety practices, the average annual dose to radiation workers at the
University of Southern Maine is expected to be well below 0.5 rem.
The NCRP recommends, and the State of Maine requires in its regulations, that the annual whole body
dose to radiation workers not exceed 5 rem. However, it is USM’s policy to take action if the annual
dose is likely to exceed one-tenth of that amount, or 0.5 rem.
The State of Maine also requires that the total dose to the embryo/fetus not exceed 0.5 rem during the
entire period of gestation from occupational exposure of a declared pregnant woman. In addition, all
efforts should be made to avoid month-to-month variation in the dose.
3. Radiation Safety Practices
In order to keep personal exposure as low as reasonably achievable (ALARA), each radiation worker
should practice these radiation protection measures:
a) Time – Keep the time during which you are actually exposed to ionizing radiation to a minimum.
b) Distance – Maintain the maximum distance possible between yourself and the source of the
ionizing radiation.
c) Shielding – Protect yourself with shielding when you are in a radiation area. Remember, the
shielding should be placed between the source of the radiation and your body.
4.
Declaration of Pregnancy
The policy of the University of Southern Maine regarding occupational exposure of pregnant
women is as follows:
a) A pregnant radiation worker may declare her pregnancy and estimated conception date in writing to
the RSO (See Appendix O). She should meet with the RSO to discuss her exposure history and
protective measures. This information will remain confidential. The RSO will keep a separate record
of the radiation exposure to the pregnant employee.
b) During the gestation period, the dose to the fetus should not exceed 0.5 rem, and the dose should not
exceed 0.05 rem in any one month.
c) In order to help achieve this goal, it is mandatory for all personnel to use appropriate protective
devices and follow accepted good laboratory practices.
d) Pregnant radiation workers will not be excused from performing their normal duties since experience
indicates that occupational exposures from these procedures do not represent any demonstrable
hazard to the fetus. Conversely, pregnant radiation workers will not be routinely assigned to nonoccupationally exposed areas against their will (for example, a forced transfer to clerical duties).
16
e) A pregnant employee who feels that her fetus is in jeopardy despite all the measures taken to protect
it, and despite all of the scientific information available as outlined above, may resign or be considered
for a leave of absence in accordance with USM Human Resources Policies.
f) The declaration of pregnancy remains in effect until the declared pregnant woman withdraws the
declaration in writing, or is no longer pregnant.

Ordering of Radioactive Material
1. All orders for radioactive materials will only be placed by persons authorized in writing by the RSO to
do so.
2. Completion and submittal of Appendix B (Application for Authorised User – Non Human Use of
Radioactive Materials) and Appendix C (Application for Non Human Use of Radioactive Materials)
must be received and approved by the RSO and Radiation Safety Committee prior to ordering of any
radioactive materials.
3. Orders for radioactive materials to be used for in-vitro clinical or any research purposes may only be
made for purposes approved by the Radiation Safety Committee.
4. Orders will not be placed until it is verified that the activity of the received material will not cause
appropriate possession limits to be exceeded.
5. Approved orders for radioactive materials will be placed by the University Environmental Health and
Safety office following current USM purchasing policies and will be billed to the requesting department.
12.0
Receipt of Radioactive Materials
1. Once an order is placed the University Environmental Health & Safety office will notify the PI and
Research Administration Office of the details of the order and the estimated shipping date and carrier.
Research Administration will contact the carrier and confirm the shipping and tracking information to
ensure that the carrier has the correct delivery information, details, and arrange to have staff available to
receive the shipment at the time specified by the carrier and in accordance with the order delivery
specifications.
2. Packages will only be accepted during normal working hours (8:00 AM to 4:30 PM, Monday through
Friday) at the Science Building new wing loading dock designated as 70 Falmouth Street, Portland, ME
04104.
3. All packages with radioactive material warning labels shall be inspected and, if undamaged, delivered
directly to the Radioisotope Core Facility. If a trained person with access to the Radioisotope Core
Facility is not immediately available the undamaged package will be placed in the deliveries lock box
located in room 178 of the new wing of the Science Building. Once a trained person with access to the
Radioisotope Core Facility is located, that person will retrieve the lock box key from the Radioisotope
Core Facility, retrieve the package and transport the package to the Facility. The lock box will be
surveyed each time it has been used to house a radiation labeled package, or at any time there is
suspicion that contamination may have occurred. Each survey will be properly documented. (See
Appendix G)
17
4. If at the time of delivery an inspection reveals damage to the package or if the package is wet the
package and the delivery person will be kept at the loading dock until the package has been scanned and
is shown to be safe. If the scan reveals that there is radiation present above limits specified by law,
regulation or policy, the standard radiation spill procedures will be followed and documented (See
Appendix A).
5. Once at the facility, a trained person will perform the package opening procedure and fill out the receipt
log. The following procedure should be followed:
a) Verify that the package is addressed to USM.
b) Visually inspect the package for damage (stains, crushed corners, leakage, puncture holes, etc.).
If the package is damaged do not accept it and require the courier to remain on site until the
Office of Campus Environmental Safety and Health has been notified (x 5406). They will then
supervise the handling of the damaged package.
c) If the package is not damaged, sign for it and release the courier. Contact the research isotope
procurement coordinator within the facility to pick up the package.
d) If questions arise or in case of an emergency, contact the University Environmental Health and
Safety office.

Opening Packages Containing Radioactive Materials
The procedures to be followed for opening packages depends on whether or not the package has radioactive
material warning labels on it.
1. For Packages With Warning Labels
a) Put on gloves to prevent hand contamination. If the package contains liquids, place it on an
absorbent pad.
b) Visually inspect the package for any sign of damage (e.g., wet or crushed). If damage is noted,
stop the procedure and notify the University Environmental Health and Safety office.
c) Record the date, time, box or lot number, P.O. number, radionuclide, radiation units on label,
transport index on label, and your initials on the radioactive shipment receipt report.
d) Use a survey meter to measure the exposure rate from the package at 1 meter and at the package
surface, compare these to the acceptable levels, and record the results on the report. The action
levels depend on the label. They are (in mR/hr):

2. These inventories are performed by the RSO and reviewed by the RSC, and are examined for
compliance with appropriate possession limits. A record of total activity on hand at the time of the
inventory will be recorded. (See appendix I)
18.0
Waste and Transfer of Radioactive Material
1. Categories of Waste: All waste containing radioactive material, at any level, must be disposed of in
accordance with applicable City, State and Federal regulations. As a general rule, radioactive waste falls
into one of several categories depending on the half-life of the radioactive material and its activity:
a) Short Half-life Material
Radioactive waste containing short half-life material is usually handled by placing the waste in
storage, allowing it to decay to background, and then disposing of the remaining waste without
regard for the formerly radioactive material. If, after decay of the radioactive component, the
remaining waste is chemically and/or biologically hazardous, it must be handled appropriately.
Otherwise, it may be disposed of as normal trash. In some cases, short half-life waste may be
returned to suppliers of such material. Examples of short half-life material are Iodine-125,
Iodine-131 P-32, etc.), and associated instruments, containers and protective clothing and
coverings.
b) Medium and Long Half-life Material
Radioactive waste containing long half-life material in encapsulated sources is usually handled
by return to the manufacturer. Examples of such waste include calibration sources (Cesium-137,
Cobalt-57 and I-129). Un-encapsulated sources (Tritium, Iodine-125, Carbon-14, Sulfur-35,
etc.) may be stored for decay to background, stored for eventual shipment to a disposal site, or
stored for disposal by other means. The choice of a method to use will depend primarily on the
type and activity of the waste, and must be approved by the Radiation Safety Officer.
2. Approval of Waste Disposal: All disposal or transfer of radioactive material must be approved by the
RSO. Blanket approval may be given for well-established methods of disposal. Each area using
radioactive material must adhere to the written procedures specific to its use.
22
3. C14 contaminated liquid waste can be disposed of through the sanitary sewer provided the liquid is
biodegradable and the amount of isotope is below release limits established according to USNRC Part
20 Appendix B. The current limit is 3 x 10-4 uci/ml.
4. General information: Sharps, including pipette tips, shall be placed in appropriately marked sharps
containers. Waste must be segregated by isotope. Waste shall initially be placed in dedicated containers
in the radioisotope core facility. The appropriate log must be filled out each time material is placed in a
waste container. When the container is full, it will be transferred to the radioactive waste storage room
(Science 61B). Determination of which waste is decayed to background and which waste is transferred
via a licensed broker to an approved radioactive waste facility, will be made by the RSO with the
approval of the RSC.
5. Records: Complete records of disposal or transfer of radioactive material must be maintained and
available for review by the RSO. Such records must include the isotope, activity, disposal date and the
initials of the person preparing the waste. (See appendix J)
6. Transfer of Radioactive Material: Radioactive material may be transferred between different locations
that are part of the same facility license. If transfer takes place between physically different locations,
all requirements of the Department of Transportation (DOT) must be met, including labeling of
containers and vehicles. Transfer to other licensees may be accomplished if there is mutual agreement
between the licensees and the receiving licensee is authorized to use the type and activity of the
radioactive materials to be transferred.
19.0
Personnel Monitoring – Dosimetry Use
1. Criteria for Inclusion: All employees of USM who are likely to receive on an annual basis from external
sources an exposure in excess of 10% of the maximum permissible dose limits, shall be required to wear
a whole body dosimeter to record exposure. The maximum permissible annual dose limits are:
Area
Annual Effective Dose Equivalent
Whole body
5 Rem (50 mSv)
Lens of eye
15 Rem (150 mSv)
Skin or extremity
50 Rem (500 mSv)
Any other organ
50 Rem (500 mSv)
2. The maximum permissible dose for a minor employee is 1/10 the values listed above.
3. Furthermore, a declared pregnant employee will be monitored to assure that the dose to the embryo/fetus
does not exceed 0.5 Rem (5 mSv).
4. In addition, any area where an adult employee is likely to receive an intake greater than ten percent of
the applicable Annual Limit on Intake (ALI), or where minors or pregnant women are likely to receive a
committed effective dose equivalent greater than 0.05 Rem (0.5 mSv) will be monitored to ensure
compliance with these limits.
5. When appropriate, the RSO may authorize monitoring of other individuals and/or groups of workers.
23
20.0
Information for Personnel Wearing Personal Dosimeters
Should the RSO determine that an employee may be exposed to radiation levels in excess of 10% of
annual dose limits described in Section 19, a whole body dosimeter will be issued at no cost to the
employee of the University of Southern Maine.
The personal dosimeter consists of two parts: the radiosensitive material and filters encased in plastic,
and a plastic clip-on holder.
The following rules must be followed to insure accurate and timely measurement of your occupational
radiation exposure:
1. Wear the dosimeter on an anterior pocket or collar with your name facing away from your body.
2. If using a lead apron, wear the dosimeter outside the apron. This is required by State of Maine
regulations.
3. When not wearing your dosimeter, store it in a place where it is not near any sources of radiation.
4. Never wear the dosimeter when you are a patient and a medial x-ray exam is performed on you. The
dosimeter is used to measure occupational radiation exposure.
5. Never intentionally exposure your dosimeter by placing it near a source of radiation. Exposing your
dosimeter “just to see what happens” will result in an invalid measurement of your occupational
radiation exposure. An investigation will be conducted by the RSO.
6. Your dosimeter will be exchanged prior to the first day of each calendar quarter with a new devise. A
representative from the EH&S office will exchange the new dosimeter for the devise used in the
previous quarter. It is imperative that the quarterly exchange occurs and that the “old” dosimeters are
returned to the vendor for analysis and reporting.
7. Please note: Individuals who make the dosimeter exchange process challenging, or frequently lose
dosimeters, can be restricted from future activity involving radioactive materials if the RSC deems this
action necessary.
8. If you lose your dosimeter, promptly contact the University Environmental Health & Safety office
(x5406). A new dosimeter will be issued to you. (See appendix K)
9. After the dosimeters are collected each quarter, they are sent for processing to the vendor (Landauer). A
report of the radiation exposure received by each individual is sent to the RSO at USM. The RSO promptly
reviews the report and posts a copy so that you can also review your readings. Copies of all reports are kept
on file in the University Environmental Health & Safety office.
10. The Maximum Permissible Dose (MPD) to the whole body allowed by the State of Maine for
occupationally exposed workers is 5000 millirem per year. The eyes, skin, extremities and other organs are
allowed higher doses. However, investigational levels for occupational radiation exposure at USM are set
at 1/10 and 3/10 the MPD and are given below.
24
11. Based on exposure records for the previous five years, advise from Wayne Malloch from the State
of Maine Radiation Control Program, and a unanimous vote from the The Radiation Safety
Committee, it was decided on 6/20/2012 that dosimetry use could be safely suspended. Should use
of more energetic isotopes be proposed in the future, resumption of dosimeter use could result
based on potential exposures and RSO / Radition Safety Committee actions.

If you have any questions concerning personal dosimeters or radiation safety, please contact the
Radiation Safety Officer at 780-5406.

Radiation Safety Surveys
Surveys utilizing a survey instrument appropriate to the energy and allowable radiation levels must be
conducted in all areas on a routine basis and whenever contamination is suspected.
The frequency of surveys depends on the classification of the laboratory (see previous section,
“Laboratory Classification”).
1. Work areas in Type A laboratories must be surveyed each day of use.
2. Work areas in Type B laboratories must be surveyed weekly.
3. Work areas in Type C laboratories must be surveyed monthly.
4. Any area that is used by more than one research group must be surveyed before and after use by any
individual or research group.
5. The package receipt area must be surveyed after any package is opened.
6. The action level for any controlled area is 0.5 mR/hr. For uncontrolled areas, the level is 0.05 mR/hr.
7. All Surveys must be documented. (See appendix L)
25
22.0
Wipe and Leak Tests
Wipe tests of areas that may be contaminated with radioactive material and leak tests of sealed sources
must be assayed on instruments appropriate to the energy and allowable radiation levels. Tests must be
performed on a routine basis, as described below, and whenever contamination is suspected.
The frequency of surveys depends on the classification of the laboratory:
1. Work areas in Type A laboratories must be wipe tested daily.
2. Work areas in Type B laboratories must be wipe tested weekly.
3. Work areas in Type C laboratories must be wipe tested monthly or upon completion of work with an
isotope.
4. Any area that is used by more than one research group must be wipe tested before and after use by any
individual or research group.
5. The package receipt area must be wipe tested after any package is opened. (See appendix M)
a. All wipe test results must be documented.
b. Action levels depend on the radiotoxicity of the radionuclide. They are (in DPM/100 cm2):

Bioassays
Bioassays will be performed on all personnel who handle un-encapsulated sources of tritium (H-3), I125 or I-131 above specified amounts to assure that the amount of material retained by the body is
below acceptable limits. (See appendix N)
1. Tritium (H-3): Any individual who handles more than 10 mCi of tritium in a single day in unsealed,
dispersible or volatile forms will receive a bioassay. The assay must be conducted within the calendar
month in which the material was used. A liquid scintillation counter will be used to assay urine samples
provided by the employee. Any results greater than 4 uCi/l or urine must be reported immediately to the
RSO.
2. I-125 or I-131: Any individual who handles more than 1 mCi of either I-125 or I-131 in a single day in
an open room or bench, or who handles more than 10 mCi in a single day in an adequately designed
fume hood must receive a bioassay. Persons handling solid forms or sealed sources are exempt from
this requirement. For I-125, the assay must be conducted between 24 and 96 hrs after the material is
26
handled. For I-131, the assay must be conducted within 3 days after handling. The assay will be
conducted by measuring the thyroid burden in-vivo.
A scintillation detector appropriately set for the isotope in question will be used. Any results greater
than 0.12 uCi of I-125, or 0.04 uCi of I-131 must be reported to the RSO immediately. Any results in
excess of 0.5 uCi for I-125 or 0.24 uCi for I-131 will require therapeutic counter-measures.
24.0
Procedure for use of Survey Meters
All the survey meters are battery operated portable radiation detection instruments. A Geiger-Muller probe
is attached to each unit with a cable. The steps given below should be followed when making a radiation
survey:
1. Inspect the instrument for mechanical defects such as a broken dial, loose knob, or frayed cable.
2. BATTERY CHECK: Turn the range switch to "BAT". The meter needle should deflect to the "BAT.
TEST" portion of the meter scale. Contact the University Environmental Health and Safety office if the
needle does not deflect to the correct region. This may be an indication that new batteries are needed.
3. BACKGROUND MEASUREMENT: Be sure that you are in an area where only natural background
radiation is present. Turn the range switch to X0.1. Remove the probe from its holder, and hold it as far
away as possible from the check source. Read the appropriate scale on the meter and multiply the reading
by 0.1 to determine the exposure rate in mR/hr.
4. CHECK SOURCE TEST: Turn the range switch to the appropriate setting. A check source is attached to
the side of the meter. Lift the cover of the check source box, exposing the surface of the source. Remove
the probe from its holder and place the probe face directly against the check source box, making sure it is
centered. Read the meter and compare the reading with the expected value listed on the calibration sticker
on the side of the instrument. The reading on the meter and the expected value should agree to within +/5%. If the reading is not within this tolerance, check to see that the probe face is centered to the check
source, and that the correct range has been chosen. If the problem persists, contact the University
Environmental Health and Safety office.
5. AUDIO TEST: While the probe is still next to the check source, turn the audio switch on and check that
it functions. The audio switch may be turned off if its use to not desired.
6. MEASUREMENTS: Turn the range switch to X0.1. Remove the probe from its holder and hold the
probe face 1 cm away from the surface to be surveyed. Move the probe slowly over the entire surface
that is being surveyed. Read the appropriate scale on the meter and multiply the reading by 0.1, to
determine the exposure rate in mR/hr. (If the needle is off-scale, turn the range switch to X1 or X10 and
survey the area.)
7. When all surveys are completed and recorded, turn the audio switch and the range switch to their "OFF
positions.
a. This survey meter has a calibration label which states the date its next calibration is due. Contact
the University Environmental Health and Safety office approximately one month prior to this due
date to arrange for calibration and batter replacement.
b. Calibration is performed annually, as required by USM’s Limited Scope Materials License.
c. The procedure for use of the BETA COUNTER is posted with the instrument in the laboratory.

As Low As Reasonably Achievable (ALARA) Policy
The Radiation Safety Committee and RSO of USM is committed to the program described herein for
keeping individual and collective doses as low as reasonably achievable (ALARA). In accordance with
this commitment, we hereby describe an administrative organization for radiation safety and will
develop the necessary written policies, procedures and instructions to foster the ALARA concept within
USM.
1. The RSO will report the status of the radiation safety program, including ALARA considerations to the
RSC at least annually. This will include reviews of operating procedures as well as past dose records,
inspections, etc. and consultations with outside consultants.
2. Modifications to operating and maintenance procedures and to equipment and facilities will be made if
they reduce exposures unless the cost is considered to be unjustified. The RSO will be able to
demonstrate, if necessary, improvements have been sought, that modifications have been considered and
that they have been implemented when reasonable. If modifications have been proposed but not
implemented, the RSO is prepared to describe the reasons for not implementing them.
3. In addition to maintaining doses to individuals as far below the limits as is reasonably achievable, the
sum of the doses received by all exposed individuals will also be maintained at the lowest practicable
level.
4. The RSC based on advise from the RSO established the investigational levels listed below in Tables A
and B. The RSO will perform regular reviews of occupational exposures with particular attention to
instances in which the investigational levels are exceeded. The principle purposes of this review are to
assess trends in occupational exposure as an index of the ALARA program, and to decide if action is
warranted when investigational levels are exceeded.
5. The RSO will also perform monthy radiation surveys.
6. The Radiation Safety Committee will audit the RSO activities at least annually.

8. The RSO will ensure that authorized users, workers and ancillary personnel who may be exposed to
radiation will be instructed in the ALARA philosophy and informed that management and the RSO are
committed to implementing the ALARA concept.
9. Radiation workers will be given an opportunity to participate in formulating the procedures they will be
required to follow. The RSO will keep in close contact with users and workers and will receive and
evaluate suggestions of individual workers concerning ALARA.
10. Results of personnel monitoring will be compared to the investigational levels established in Tables A
above.
a) If an individual’s dose is less than Investigational Level I, no action will be taken.
b) If an individual’s dose is higher than Investigational Level I, but less than Investigational Level
II, the RSO will compare the dose to that of other workers in the same category, and will
investigate possible causes and corrective actions for the higher level.
c) If an individual’s dose is higher than Investigational Level II, the RSO will investigate in a
timely manner the cause of the reading and will take corrective action.
d) In cases where a worker's or group of workers' doses need to exceed an investigational level, a
new, higher investigational level may be established, provided it is consistent with good ALARA
practices. Justification for establishment of a new level will be documented.
26.0
Audits
1. Radiation Safety Officer (RSO): The RSO will perform audits at least biannually to insure compliance
with all applicable policies, procedures and regulations. Additional special audits may be performed

X-ray Safety Information
X-RAY CONCERNS AND PRECAUTIONS
There are several properties of X rays that make this type of radiation particularly dangerous to use in
the laboratory. X-Ray radiation cannot be sensed by humans, but some people can feel the presence of a kind of
"tingling sensation" which arises from charged air particles produced by the interaction of the ionizing X rays
with air. X-Ray radiation is also hazardous because it can appear to "bounce" off surfaces and to "bend" around
corners. This makes it important to survey each instrument for leaks after any modifications to the instrument.
At the University of Southern Maine, these checks are conducted by the campus Radiation Safety Officer.
Although X-ray instruments have the potential to be dangerous, when used improperly, modern diffraction Xray instruments pose few risks to careful users. The manufacture and use of analytical X-ray instruments is
regulated by both the federal and state governments. Current regulations require a variety of safety devices
be built into X-ray instruments that make it very difficult for anyone to even accidentally expose themselves to
the dangerous incident X-ray beam. The design of the instruments limits even accidental exposures to the hands,
arms and facial areas. Also, the types of radiation used in diffraction instruments (primarily Mo, Cu, and Kα
radiation) are considered "soft" radiation. These types of soft radiation generally will not penetrate more than 24 cm into the body.
Possible Health Effects
To date there have been few accidental exposures in X-ray diffraction labs, and the physical ailments from these
accidents have been relatively minor. Because of the soft nature of radiation used in a diffraction lab, accidental
exposure to X-ray radiation will usually cause damage only to the skin and possibly bones near the surface of
the body. Depending on the nature and extent of exposure some or all of the following medical problems may
ensue.
Often at the time of exposure, little or no pain is felt. However, 1-3 hours later, a first- degree burn forms on the
skin and a dull pain settles in all exposed tissues. Sometimes this is followed by swelling that turns into blisters
that finally open and do not seem to heal over. In extreme cases, skin grafts and/or amputation are required.
Exposure of soft X rays to the eyes may cause permanent cataracts to form. Because of the possibility of
cataracts forming, it is recommended that glasses be worn in an X-ray diffraction lab whenever instruments are
modified or aligned.
As with all types of ionizing radiation, X Rays cause the most damage to rapidly growing,
undifferentiated cells. Thus, women that are pregnant or suspect that they are pregnant, should take special
care to protect their fetus, especially during the first trimester. Women that are pregnant or suspect that
they are pregnant and wish to avoid exposure should contact the lab director in order to make arrangements to
get data collected by someone else during the course of their pregnancy.
42
Electrical Hazard
Another serious hazard from an X-ray diffraction instrument is electrical shock. The X- ray generator is a highly
regulated DC power supply that operates at applied voltages of 40 to 60 kV in order to achieve an optimum flux
of X rays. Also, the power supply that feeds the detector operates at about 1 kV. These power supplies should
only be serviced by trained electrical engineers. Also note that the X-ray generator has several large capacitors.
Even when the instrument is turned off, these capacitors store sufficient power to injure and possibly kill a
person. All work on any X-ray generator should be done only by personnel trained in high-voltage electronics.
Safety Procedures
1. All users of x-ray producing equipment must first become "authorized users" by completing the
requirements of the USM Radiation Safety Program. They must also read the safety information above
and agree to abide by the following rules.
2. No unauthorized personnel may defeat or override any safety features on the X- ray generators, the
safety enclosures, or the goniometers including the collimators, tube shields and shutters.
a) No user may employ any power or hand tool on any part of the goniometer, detector, or low
temperature device without express instructions from the lab director. The single exception to
this rule involves the use of specific wrenches to adjust the position of the sample on the
goniometer head and to adjust the position of the video camera to view the sample.
b) All actual or suspected X-ray exposures of any person should be handled in the following
manner.
3. Medical emergencies must be treated according to the Workers Compensation Program
requirements. Call 911 for emergency transport.
4. If the exposure was due to a malfunction of the instrument, depress the red "X-RAY OFF” button on the
either side of the generator before leaving the lab. If time permits tape a message to the front of the
instrument noting "INSTRUMENT PROBLEM" and include your name, the date and your telephone
number.
5. Report the incident to the University of Southern Maine Radiation Safety Officer at 780-5406 and to the
X-ray device owner. If medical treatment is required, notify the chairman of your department.
Small electrical fires may be put out by using fire extinguishers located in the lab.
Larger fires and medical emergencies should be handled as described in your department's safety meetings. In
the case of large room fires or major water leaks, be sure to turn off the X rays by pressing the red "X-RAY
OFF" button on the front of all X-ray generators. Be sure to contact the lab director for any lab-related
problems.
