General Radiological Sa fety Procedures:
The control procedure for use,f rad', active material requires t he preparation of a Standard Operating Procedure (SOP) as described in the Naval Surface Weapons Center Sa fet y Manual (P5100.5A) by the responsibic supervisor.
The SOP is reviewed by the Division IIcad, and if approved, is forwarded to IIcalth Physics for general review and -
consideration as to the adequacy of sa f eti requirements.
After review and approval, the SOP will be forwarded to the investigator's Department llead for final review and approval.
Th'c itcalth Physics Branch is responsible foi the protection of laboratory-personnel and environment from radiological hazards.
This includds adequate radiological safety meaaures for all laboratory personnel who work in spaces where radioactive material is used and/or
- stored, Special monitoring is performed on a case. basis or when requested where any experimental or maintenance operation may involve an unusual radiological hazard.
Ilealth Physics also conducts monitoring surveys and contamination wipe surveys of all areas wher e radioactive materia]
is used and/or stored.
These services include special monitoring of film badges, pocket dosimeters, and appropriate radioclinical examina-tions for evaluation of internal contamination.
These examinations will be conducted at the Naval Medical Center in Bethesda, Maryland, when required.
A supply of calibrated portable monitoring instruments, adequate to measure all types of radiation, are provided by the Naval Electronic Systems Command, Washington Navy-Yard, Nashington, DC 20390, for the Ilealth Physics Branch, and for use by investigators for self-monitoring purposes.
The Environmental ~ Laboratory in building 71, and building 70 i
(room 1.41 ), a re designa ted as rest ricted a reas and, as such, are provided with necessary locks and interlock systems, and are posted with appropriate radiation warning signs and 6ther identifying informa-
- tion, All persotmel who work in the area when radiological material 1 1
is utilized are required to follow radiological safety p: cedures.
Film liadges at e worn by all personnel.
Monitoring'by users of them-selves and work areas tith portab.le instruments are carried out frequently.
Pocket dosimeters are read a f t er use by users and documented whenever they could receive an exposure to radiation of 100 mrem / week or more.
h'henever a dosimeter goes of f scale (over 200 mr)., the person will stop work and notify the llealth Physics 11 ranch immediately.
llealth Physics.will investigate the incident to determine If the exposure is accurate or a malfunction of the dosimeter.
If it is ascertained that
~
the exposure is accurate, precautions will be instituted to prevent further exposure of this magnitude.
It is not anticipated that the use of the listed sources will produce radioactive aerosol or waste.
Radiochemistry operations with small quantities of SNM material will provide a medium amount of radio-active waste, and in the event of a leak from a sealed source, any quantity of radioactive waste generated, as well as waste from its i
subsequent decontamination, will be placed in specially marked solid i
and/or liquid radioactive waste containers for all radioactive wastes.
Disposal will be to a licensed contractor.
Air sampics will be collected should the possibility of generating a radioactive aerosol be likely to occur.
1 An Automatic Gamma Alarm or a s imila r area monitor will be provided 1
within a distance of 20 feet from the experimental set-up when large quantities (one Curie or more) of scaled sources are used.
The alarm

s
.S
'is set to be activated by radiation at 2 mr/hr.
Th is. ins trtmen t is equipped with both an audible and visibic alarm to indicate any increase in radiation background level.
No. radioactive material will be moved within'the Laboratory without prior approval and documentation by the llcalth Physics liranch personnel in accordance with this license application.
Collection and Disposal of Radioactive Wastes:
]
Solid Wastes Special waste. containers with disposable liners are provided by the Ilealth Physics liranch to the carious departinents utilizing licensed radioactive materials for the collection and temporary storage of low-level cadioactive wastes.
These receptacles are yellow in color and contain the magenta radiation symbol and the wording "Caetion - Radio-active Materials",
The IIcalth Physics llranch is responsible for collectiiig the contents of these containere on a routine basis (monthly or more aften as required).
Collected wastes are then placed in storage under the direct supervision of IIcalth Physics prior to ultimate disposal to a commercial waste disposal company.
t 1,iquid Wastes Special containers will be provided to laboratories employing liquid radioisotopes for the col'lection and containment o f medium-level wastes.
These radioactive wastes will consist primarily of first-wash ~ solutions.
Further washings 'of glassware will be restricted to certain designated sinks located in each of the labora tories using radioisetopes.
A,
a 6
1000 gallon capacity holding tank is situated appioximately ten feet from the' south'wn11 of the radiochemistry building (building 343) for the retention of medium-IcVel liquid wastes.
The contents of this tank will be periodically sampled ' for radioacti'vity hy llcalth Phys' s pers.onnel when the icyc1 reaches 850-950 galions.
Ultimate Disposal
' Solid radioactive whstes and containers containing liquid wastes
'will ultimately be disposed of to a commercial fi rm thr'ough an inter-service agreement between the Army and the NSWC.
Records will be maintained by the llcalth Physics Branch of the 2
kinds, quantities, and dates of all radioactive 8.isposals.
Contamination Limits:
j Internal The Radioa;tivity Concentration Guides (RCGs), as recommended by the International Commission on Radiological Protection will serve'as the Laboratory guide with respect to contamination internal to the body.

Criticality Precautions:
Although the Pu239F4 source with its containment has been deemed nuclear safe, the following additional precautions will be followed:
j.
a, lixperiments involving this special nuclear material will' be isolated from other such experiments.
To conform to the above, no other special nuclear material will be used or stored in these facilities (Environmental 1.aboratory, building 71;'or room 141, building 70) during' u'se : or s torage of this sourc-
)uffer distance of at least 12 feet will be' required between other possible neutron sources within other l
l areas o'f buildings 70,and 71.
b.
The basic configuration of the source shall not be altered
~
t in any Way during tise.
Special precautions are required to assure that the inadvertent accumulation of a sufficient quantity of special nuclear materials 235, Pu 39, or other fissionable material) necessary to create (U233, (3 2
a critical mass with an attendant nuclear chain reaction will not happen.
Requirements are as follows:
j Unsealed Quantities of Special Nuclear Material l
One " unit" is defi.ned as 250 grams of any unsealed special nuclear material.
No more than one unit may be us;d in a room at any time.
No quantities of unsealed special nuclear material greater than one gram may be used in rooms adjacent to a room where one unit is being used.
The llealth I'hysics Branch must be noti fied in advance before gram quant ities
~
of unsealed special nuclear material may be moved from any room.
Quantities of special nuclear material greater than one gram not in use shall be stored under the care of the Ilealth Physics Branch in building 321.
Because of the above precautions, an exemption is requested from the Code of Federal Regulations (10 CFR), part 70.24.

l The " scaled source" con figuration must meet the criteria i
established in TID-7016, "Nuclea r Sa fety Guide",,for subcriticality i
by virtue of quantity, size, vo'ume of dimension before procurement or use in the laboratory.
In addition, the hasic configuration of the scaled source shall not be altered in any way during use.
Additional quantities of special nuclear materials shall not be used or stored in the same or in adjacent rooms.
Decontamination:
Area Decontamination Decontamination of a work area shall be done by perscnnel normally ustag the space or by the Public h'orks Department personnel, depending i
i upon the type 'of ef fort required.
IIcalth Physics personnel shall per fo rm all necessary monitoring surveys, make recommendations for decontamination procedures and arrange for participation of other personnel, as necessary.
Equipment Decontamination For uncontrolled use it is mandatory _that all equipment be decontaminated to final or standard cicarance levels as shown above i
for alpha emitters.
Arrangements for equipment decontamination shall l
be made in accordance with controlled maintenance work as described above.
Personnel Decontamination First wash thoroughly with soap and water af ter working with radio-i active materials.

high and/or unusual radiation exposure is revealed, the individual arul his/her supervisor are informed immediately of the film badge findings.
Ilealth Physics Branch then conducts an investigation to determine the cause of the exposure and the necessary precautions t
l to prevent a reoccurrence.
3.
If the exposure IcVel exceeds.5 Rem, the individual shall be j
I re fer red t o the h'OL Medical Department for medical examination.
Th is is required by NAYMED P-5055.
4.
Personnel working in high radiation areas and/or any other place that a person could receive a whole body exposure of 100 mr/hr are i
required to wear two pocket dosimeters, in addition to film badges.
5.
Each individual working with neutron emitting sources will be issued a lithium fluoride thermoluminescent dosimeter (LIF TLD).
The range of the LIF'TLD is 00.005 to 1 x 105 Rem for gamma radiation and 5
00.030 to 1 x 10 Rem for neutron radiation., The proc ssing of 1
the LIF TLD is the same as for the regular film badges.

Special Requirements Governing the Purch'asiny Receiving,_ and Shipping g
of Radioactive Material:
All purchasing, shipping, and rocciving shall he done in compliance with the regulations of NRC and DOT.
Radiation Sa fety Training:
New employees and etudents are given radiation sa fety training by the Radiation Sa fety Of ficer prior to use of licensed material.
All radia tion safety training is documented and filed in the licalth Physics Branch.
Training films and Icctures are used to highlight speciric l
areas of interest.
Basic fundamentals of health physics such as the use 1
i of pcrtable instruments tor radiological surveys, standardization and l
calibration of fired instruments, sample preparation, and Icak testing are stressed.
Training in mathematics is necessary.to enable the employee to calculate source decay, the amount of radioact ive material (in curies) in leak test samples, air sanples, water sampics, and wipe sanples.
Retraining will be conducted as special occasions arise.
Radiological safety and health physics tra!.ning for llcalth Physics personnel is provided by the Navy Nuclea r Power Unit, Port llueneme, 1
l California; Department of Ilealth and Iluman Services, Oak Ridge National l
hahoratory; private and other Governmenta'l training facilities.

1 Emergcncy Action:
l.
In the. event of an emergency such as source positiener jamming, container hang-up, fire in room involving the source (s), or loss of power, the following immediate action must be taken:
a.
Evacuate all personnel from the immediate area to an area in which the radia tion leve.Is are less than two milli.
roetgen per hour (mR/hr)-
b.
Secure area and post a guard to prevent unauthorized entry.
Erect a sign stating the nature of the hazard and the operator's name and extension.
c.
Contact the RSO immediately and other appropriate personnel as the situation deems necessary (i.e.,
fire departmen't, h'OL gua rd, sa fe ty o f ficej.
E ALARA Concegt:
When procedures are reviewed by the Radiation Safety Commit tee, the l
evaluation shall include a consideration that the procedure meet a commit-
'ent to reduce radiation exposures to as Jow as reasonably achievable.
