The description of the sources are as follows:

a i

a.

Eighty grams of Plutonium 239 io mixed homogeneously with beryllium in 1

proportions that give the maximum neutron flux.

b.

Two grams of Uranium 235 (enriched) is incorporated in a neutron detector.,

f Five hundred (500) micrograms of Plutonium 239 are electrolytically c.

l deposited on metal plates and are (1)

Four sets of AN/UDM-6 Plutonium calibration sources manufactured by

~

Eberline Instrument Corporation. Each set consists of four each metal disk sources electrolytically deposited with Plutonium. The four disk sources in the sdt ccntain approximately 20 micrograms, 2 micrograms, 0.2 micrograms, and 0.02 j

micrograms of Plutonium.

[

'j i

(2)

Three sets of rectangular calibration sources manufactured by '

Eberline Instrument Corporation. Each set consists of three rectangular metal plates g}ectrolytically deposited with Plutonium. The three / sources contain approximately

,60 micrograms, 6 micrograms, and 0.6 micrograms of Plutonium.

(3) Three sets of disk sources manufactured by Eberline Instrument 'Corpor-l ation. Each set consists of three each metal disk ' sources electrolytically f

deposited with Plutonium. The three sources in each set contain approximately '

1 microgram, 0.1 microgram, and 0.01 microgram of Plutonium.

1 (4)

Four each rectangular metal sources electrolytically deposited with I

Plutonium manufactured by Monsanto Chemical Company. The four sources contain approximately 1 microgram, 0.1 microgram, 0.04 microgram, and 0.02 microgram of Plutonium.

The five hundred (500)' micrograms Plutonium 239 electrolytically deposited 'on metal plates will be used by any personnel specified in para"5 below anywhere in the Unit ed States or overseas.

i d.

One each Plutonium Beryllium Neutron Sources will be in' possession 'at j

any one time. The maximum amount of Plutonium for each source is 160 grams and the total maximum at any (me time is 160 grams.

j 3.

The material is requested for an indefinite loan and the license is requested I

for an indefinite period of time.

The. Plutonium Beryllium Neutron source is used to calibrate survey' a.-

I

' instruments, neutron detectors, film badges, etc.

j i

b.

Uranium-235 is.in the Neutron detector.

i o

(.

The Plutonium 239 sources will be used to calibrate counters, surv'ey instruments, counting systems, etc.

These sources are normally kept at Sacramonto Army Depot (SAAD) except during the period when they are used at off-post locations. At these off-post locations the sources will be under the responsibility of the usei' and will be secured from unauthorized use. The user will monitor himself whenever there is a possibility.of his beccming '

i contaminated.' The following action is required in the event of a known or suspected internal exposure:

i e

i (1)

Seek medical advice from the medical officer.

(2)

Notify the Radiological Protection Officer,;AUTOVON 839-3285,'-

I ccrnmercial Area Code 916 388-3285.

d.-

The Plutonium Beryllium Neutron source ill be shipped to Sacramento Army Depot frem the field customers to be calibrated. The manufacturer type number can vary.

RADIOLOGICAL CONTROL 1.

Administration Only personnel authorized by the Chief, US Army Calibration and a.

i Repair Center - Sacramento (USACRC-Sac) will be allowed to use radioactive i

sources.

b.

Personnel directly responsible for overall radiation protection are:

1 Chief, USACRC-Sac Chief, Nucleonics Laboratory Branch' Radiological Protection Officer l

2.

Operating Instructions j

a.

Personnel Controls (1) Control relative to the exposure of persionnel to radiation will l

be in accordance with AR 40-14.

l (2) All personnel who work in the Primary and Secondary Laboratory of Nucleonics Laboratory Branch will wear a film badge and a pocket dosimeter.

Visitors and other Center personnel will be required to wear a film badges only when entering radiation controlled areas.

(3) All personnel working with or handling radioactive materials will be required to wear uniforms and will monitor themselves before eating, drinking, smoking, or leaving the work area.

(4) The results of the film badge check will be recorded on DD Form 1141, " Record of Occupation Exposure to. Ionizing Radiation," and will be maintained in the employee's personnel medical file.

(5)

Shields, remote handling tongs and other safety devices will be used as necessary for personnel safety.

Radiation Surveys 1

(1) The air in the Building 300.will be' monitored when there is a l

possibility of airborne radioactive, contamination.

(2) The results.of the air monitor will be recorded on SDSSA-QMD Form 339 and will reflect the-test location, flow rate, counts' per' minute, level of radiation, date and time of observation'and the initials. of the person

)

recording the ob'servation.

j 1

(3)

Specific areas in and around Building 300 will-be monitored monthly' I

using alpha counter or beta' gamma detection instruments.

e-(6)

Instruments used for radiation protection will be in proper opera-l ting condition and will be calibrated at least once every three months.

l 3.

Radiation warning signs and labels a.

Radiation warning signs will.be prepared with the following wordin s:

. i

.i l

(1) Caution, or Danger Radiation-Area l

1 (2) Caution, or Danger High Radiation' Area j

(3) Caution, or Danger Airborne Radioactivity, Do Not Remain in this Area (4)

Caution, Or Danger Radioactive Material (S)

(5)

Other wording as approved by the Chief, USACRC-Sac that will enhance the desired degree of safety.

b.

Specifications for warning signs:

(1)

All signs will have t. yellow background with purple or magenta letters.

(2)

Area warning signs will be of such size as to be readily legible at a distance of 20 feet to an individual with normal vision.

(3)

Signs on containers of radioactive materials will be legible at a distance of'10 feet to an individual with normal vision.

c.

^

(1) Calibration rooms and the Radioactive Material storage rocan will be posted with 18" X 18" Caution, Radioactive Material High Radiation' Area" signs.

(2)

Radiation danger labels, XSA Lab 89, will be placed on the container' of radioactive source and indicate the following information (a)

Radioisotope (b)

Activity in curies, millicuries, or microcuries (c)

Date measured

)

4.

b.

Contamination of Skin (1) Decontamination Procedures - NBS Handbook 48 and 92.

(a) For decontamination of hands and other parts of the body wash thoroughly with soap and water.

(b)

If'the contamination is localized, mask off the affected area and cleanse with swabs, before risking the danger of spreading the contaminant ' by general washing. "

4

~

(c) ~ Procedure for general hand washing are as follows:

1_. ' Wash for not less than 2 minutes, nor more than 3 minutes with mild pure soap in moderately wam water with a good lather, covering the entire affected area thoroughly. Give special attention to areas between the fingers and around the finger nails.

Do not use highly aikaline soaps or l

abrasives.

Rise thoroughly,and repeat as monitoring indicates, until the desired degree of decontamination is achieved, but not to exceed 3 or 4 times.

2.

If the above procedure is not sufficient to remove the contamination, scrub the hands with a soft brush using a heavy lather and This scrubbing is primarily to agitate the cleansing moderately warm water.

Three washes, including rinses, should be made within 8 minutes of agent.

which at least 6 niinutes should be devoted to scrubbing. Only light pressure should be applied to the brush. Rinse thoroughly and monitor.

l 3.

If the above procedures are not sufficient to remove the contamination, notify the post surgeon immediately.

e.

Major spills involving radiation hazard to personnel.

(1) Notify all persons' not involved in the spill to vacate the room q

at once.

J (2)

If the spill is liquid, and the hands are protected, right the container.

(3)

If the spill is on. the skin, flush thoroughly, i

(4).If the spill is on clothing, discard outer or protective clothing at once.
