DATA SHEET (U-235 and Pu-239) 1.
Name of applicant:
Department of the Army US Army Calibration & Repair Center-Sacramento Sacramento Army Depot Sacramento, CA 95813 2.
The description of the sources are as follows:
a.
Eighty grams of Plutonium 239 is mixed homogeneously with beryllium in proportions that give the maximum neutron flux.
b.
Two grams of Uranium 235 (enriched) is incorporated in a neutron detector.
c.
Five hundred (500) micrograms of Plutonium 239 are electrolytically dhpositedonmetalplatesandare:
(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 set c ontain approximately 20 micrograms, 2 micrograms, 0.2 micrograms, and 0.02 micrograms of Plutonium.
(2)
Three sets of rectangular calibration sources manufactured by Eberline Instrument Corporation. Each set consists of three rectangular metal plates electrolytically 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-ation. Each set consists of three each metal disk sources electrolytically dbposited with Plutonium. The three sources in each set contain approximately l' microgram, 0.1 microgram, and 0.01 microgram of Plutonium.

calibrator will be stored in the Radicactive Material Storage room in their appropriate shielded container.
b.
The outside of the container will be labeled and marked properly.
Entry to the Radioactive Material Storage Room will be limited to c.
authorized personnel only.
7.
Transporting of Sources The radioactive sources stored in the Radioactive Material Storage room will be transported in their containers.
(1) Tags will be removed from the container and placed on the appropriate position on the " source out" board when the source is taken out of the Radioactive Material Storage room. This board will be kept on the wall of the Radioactive Material Storage room.
(2) On the tag will be the following information:
(a)
Radioisotope (b)

Emergency Procedures a.
In case of emergency, notify the Chief of USACRC-Sac or Chief of Nucleonics Laboratory Branch or Radiological Protection Officer and the Post Surgeon as soon as possible when it involves personnel safety.
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 dre as follows:
1.
Wash for not less than 2 minutes, nor more than 3 minutes with mild pure soap in moderately warm water with a good lather, covering the entire af fected area thoroughly. Give special attention to areas between the fingers and around the finger nails. Do not use highly alkaline soaps or 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 moderately warm water. This scrubbing is primarily to agitate the cleansing agent. Three washes, including rinses, should be made within 8 minutes of which at least 6 minutes should be devoted to scrubbing. Only light pressure should be applied to the brush. Rinse thoroughly and monitor.
i 3.
If the above procedures are not sufficient to remove the contamination, notify the post surgeon immediately.
c.
Wounds In the event that the skin is broken in accidents while working with radioactive substances, immediate action will be taken to remove possible contamination.
(a) Wash the wound under large volumes of running water immediately (within 15 seconds) and spread the edges of the wound to permit flushing action by the water.
(b) Notify the post surgeon as soon as possible.
(c)
Report all wounds to the radiological protection officer, or Chief USACRC-Sac, or Chief Nucleonics Laboratory Branch as soon as emergency precautions have been taken.
d.
Minor spills involving no radiation hazard to personnel.
(1) Notify all other persons in the room at once.

0PERATING PROCEDURE A. MANGAN00S SULFATE CALIBRATOR -
1.
Only authorized personnel will be allowed to operate this calibrator.
2.
Obtain the key to Isotope Storage Room from the custodian of the key cabinet.
3.
Open the door to Isotope Storage Room and transport the neutron source,
to be calibrated to the Neutron Calibration Room.
4.
Check and see if it is safe to go into the calibration, room to operate the Neutron Calibrator.
If not wait until it can be used anfely, 5.
When the calibrator can b'e operated safely, place the source container i
adajacent to' the Mn SO4 tank.
I 6.
Carefully remove the cover and plug, and remotely (with a tong) pick the Neutron capsule and place it in the neutron calibration tank.
7.
Leave the room, and place the chain with radiation sign across the doorway.
I 8.
Upon completion, take chain off and remotely replace the neutron capsule into the container.
I 9.l Carefully. replace the plug and cover on the container.
- 10. Transport the source to the Isotope, Storage Room.
i 11.
Return the key to the custodian of the key cabinet.
