e-r WARNING s
RADIATION HAZARD W
V'f Use Radiac Calibrator AN/UDM 7C only under the guidance of an installation /
activity (local) Radiation Protection Of ficer and in accordance with requirements of Chapter 5,Section IV, AR.t0-5 and AR 38511.
e Pfutonium 239 (Pu239) is dangerous to living tissue. Small amounts of Pu239, when inhaled, ingested, or absorced in open cuts or wounds, can cause serious r
illness or death. To avoid accident, observe the following:
l e Use and store the calibrator only in designated radiation controlled areas.
e Do not eat, drink, smoke, apply cosmetics, or store food stuffs, drinks, tobacco, or cosmetics where the calibrators are used or stored.
- Do not allow personnel with open skin wounds to handle or work with the calibrators without the approval of the medical officer and the (local) Radiation Protection Officer (RPO).
- Prohibit loitering in the arts by unauthorized personnel.
e Handle the calibrator carefully. Do not drop, rough handle, alter or damage it in anyway. Mishandling can cause source leakage.
e Do not touch the source surface with the hands. Wear plastic or surgical type gloves which allow sufficient dexterity during calibra-tion and leak testing. Avoid contact of objects, such as tools, in-struments, and components of the set, with the sources.
- Always wash and dry hands thoroughly after handling the calibrator; monitor the hands with a low. range alpha radiac meter; repeat the washing and drying if necessary. Notify the Radiation Protection Of.
ficer if washing does not remove contamination.
e 00 NOT ATTEMPT TO CLEAN THE SCURCE OR SOURCE HOLDERS.

GENERAL INFORMATION
- 11. SCOPE This manual describes Calibrator, Radiac AN/UDM 7C (Calibrator) and covers its installation and operation. It includes instructions for initial service, operation, cleaning, and inspection of the equip-ment. The calibrator, radiac provides a calibration check for the AN/POR-54, AN/POR 56F and AN/PDR-60 Alpha Radiac Sets. Here in referred to as radiac sets. The calibrators contain plutonium which is controlled by the US Nuclear Regulatory Commission (NRC), Title 10 Code of Federal Regulations. AR 385-11 and AR 700-64 implement NRC regulations. Army wide possession and use
~
of the calibrators are authorized by a Special Nuclear Materials License issued to Department of the Army, US Army Communications. Electronics Command, Fort Monmouth, NJ 07703. The license is issued on the basis of statements concerning procedures established forthe life-cycle control of the items. The sets are issued to authorized Army calibration activities, schools, and research and development laboratories through the US Army Communications Electronics Command, National Inventory Control Print (DRSEL MME VC). Established Army supply procedures are augmented by radiological control procedures (AR 38511).
1 2.
MAINTENANCE FORMS AND RECORDS Department of the Army forms and procedures used for equipment maintenance will be those prescribed by TM 38 750, The Army Maintenance Management System (TAMMS).

(a) Review records to determine the responsible individual.
(b) Make a physical survey.
(2) If the radiac calibrator set is recovered, revise procedures as necessary to prevent a recur-
~~
rence.
(3) If the radiac calibrator set is not recovered, report the loss througn comt:tand channels to the Area Radioactive Material Control Point (AR 385-11) and to the US Army Ccmmunications-Electronics Command stating the serial number of the radiac calibrator set, the circumstances in.
volved, and the action taken to prevent recurrence.
b.
Intemal Exposure of Personnel (1) Internal exposure is the result of personnel becoming contaminated when radiactive par-ticles are inhales, swallowed, or absorbed through breaks in the skin.
(2) In the event of a known or suspected intemal exposure:

Plutonium 239 (Pu239) is dangerous to living tissue. Small amounts of Pu239, wnen inhaled, in-gested, or absorbed in open cuts or. wounds, can cause serious illness or death. To avoid accident, obs'erve the following:
e Use and store the AN/UDM 7C only in designated radiation con-trolled areas.
o Do not eat, drink, smoke, apply cosmetics,,or store food stuffs, drinks, tobacco, or cosmetics where the calibrators are used or stored.
e Do not allow personnel with open skin wounds to handle or work with the ANIUDM-7C without the approval of the medical officer and the (local) Radiation Protection Officer.
e Prohibit loitering in thearea by unauthoriped personnel.

ADJUSTABLE PROBE POSITIONER. Aligns radiac prcce over exposed source in probe positioing well. The two L snaped legs of the prete :ositioner can be ad-justed to fit the contour of the probe base by loosening two thumbscrews which engage elongated slots in the legs, S lding the legs along the axis of the slots, and then tightening the thumbscrews.The positionerwill then ce clamped to the edges of the probe.

Laak Test (Wipe Test).
l NOTE l A leak test is performed immediately upon receipt of the AN/UDM 7C and at least every 3 months thereafter, while in use.
l WARNING l Plutonium 239 is dangerous to living tissue. Handle the AN/UDM 7C and components carefully; DO NOT TOUCH THE SOURCE SURFACE. Avoid contact of objects, such as tools, instruments, and calibrator components with the sources. Wear plastic or surgical gloves when performing leak tests and during calibration.
Use commercially available 1 inch smear papers (Whatman filter papers or equivalent). A minimum of nine smear papers will be required.
OOO Number consecutively one side of each smer caper and key the numbers to each area, component, or calibrator to be smeared. Use ballpoint or china marking pen to number the papers.
4 Dampen the smear papers with water. Do not soak them.
- Put on rubber or plastic gloves.

Smear Paper Evaluation Evaluate each smear paper using laboratory equipment capable of detecting 0.001 mi ;ocurie of alpha contamination on the test sample. Record test results and maintain these records for in-spection. lf the test reveals the presence of 0.005 micrecurie or more of contamination, the user shall immediately withdraw the calibrator from use and report the condition through the Radlae tion Control Officer,(AR 38511) to the licenses wno will fumish disposition instructione and submit required reports to DA and NRC.
l N0%
h No maintenance or repair will be performed by the operator.
The US Army lonizing Radiation Dosimetry Center located at Lexington-Bluegrass Depot Activity is the only authorized facility for maintenance or repair of the calibrator. Requests for maintenance or repair will be submitted to the radioac-e tive material control point.for coordination with CECOM and the US Army lonizing Radiation Oosimetry Center.
If a using installation / activity does not have the proper laboratory equipment. the smear papers will be processed as follows:
- Place the smear papers, each separated by a sheet of pacer in a small
. envelope marked with the name and location of the user, the serial numberts) of the radioactive test sample (s) and the words: MAILROOM.
00 NOT OPEN. Seal the envelope for forwarding.
ein CONUS, forward the smear papers for evaluation using official mail handling channel to, Chief, US Army lonizing Radiation Dosimetry Center, ATTN: ORSMI-MCJ-DC, Lexington, KY 40511.
eCommanders at overseas installations will comply with procedures established by the responsible commander.

This manual cannot list all malfunctions that may occur, nor all tests or inspections and corrective actions. If a malfunction is not listed or is not corrected by listed ~ corrective ac* ions, notify your supervisor.
.h Table S1. Troubleshooting MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 1.
SOURCE DAMAGE.
Step 1.
Use a similar type radiac calibrator and obtain a set of readings.
Step 2.
Compare the two sets of readings with readings obtained from damaged calibrator before damage occurred.
- If readings are still erroneous, contact ARRCOM National Maintenance Point (NMP) and request maintenance or repair.
2.
Call 8 RATION mal. FUNCTION.
Step 1.
Verify that the radiac set is intended to be calibrated with the calibrator.
h Step 2.
Verify that the correct accessories (i.e., source and at.
4 tequator) are being used for the radiac set being calibrated.
!! a malfunction still exists, return the radiac set to the using activity for maintenance or repair.
