standard sources are 2-inch diameter stainless-steeldisks. A coating of Pu239 (1-inch diameter) is appliedto the surface of one side of each disk. A nonradioactiveframe (1/2-inch wide) is around the radioactive surface.The frame is marked with the manufacturer's codenumber, two radiation symbols, and the alpha countingrate of the calibrated source. Each source is attached toa jig with screws.
c. Jigs. The jigs are made of anodized aluminum. Thejigs are designed so that when the probe of the radiacbeing calibrated is placed upon the jig it is the properdistance above the standard source. The jigs are arrangedfrom left to right in an ascending sequence according tothe alpha counting rate of each source. The countingrates are approximately 1,400 (1.4 x 102), 14,000 (1.4x 10), 140,000 (1.4 x 105), and 1,400,000 (1.4 x 10')counts per minute, respectively. The alpha counting ratemarked on each source is accurate to within ± 4 percent.(If the radioactive sources are accidentally touched, thecounting rates of the sources may be altered sufficientlyto warrant recalibration.)
d. Mask. The mask is a flat rectangular sheet of per-forated stainless steel. It is designed to fit in any of thefour jigs. The portion of the mask that ties flat directly
over a radioactive standard source cuts the alpha parti-cle counting rate to 38 percent of the normal countingrate.
e. Case. The case for the AN/UDM-6 is a wood boxwith a hinged cover. When the case is fully open, thecover lies flat. A label (fig. 1-2) is affixed to the top ofthe case.

WARNINGS
Use the AN/UDM-6 only under the guidance of an installation/activity (local) Radiation Pro-tection Officer and in accordance with requirements of Chapter 5, Section IV, AR 40-5 andAR 385-11. 1
Plutonium 239 (Pu239) is dangerous to living tissue. Sm&l amounts of Pu239, when inhaled,ingested, or absorbed in open cuts or wounds, can cause krious illness or death. To avoid acci-dent, observed the following:(a) Use and store the AN/UDM-6 only in designated radiation controlled areas.(b) Do not eat, drink, smoke, apply cosmetics, or store food stuffs, drinks, tobacco, or
cosmetics where the AN/UDM-6 is used or stored.(c) Do not allow personnel with open skin wounds to handle or work with the AN/UDM-6
without the approval of the medical officer and the (local) Radiation Protection Officer.(d) Prohibit loitering in the area by unauthorized personnel.
2-1. Service Upon Receipt of Equipmenta. Perform the required DOT radiation surveys and
wipe tests of the AN/UDM-6 package (AR 385-11 andAR 700-64).
b. Unpack the AN/UDM-6.C. Inspect the wood case to see that it is undamaged
and that the label (fig. 1-2) is attached to the cover.
d. Put on protective gloves.e. Open the case fully. Remove the cushioning pad
and set it in the cover of the case. Check the mask tomake sure that it is flat. If the mask if deformed (doesnot lie perfectly flat), it is unserviceable. A deformedmask will not provide the proper transmission factor,may come in direct contact with a radioactivi sourceand damage it, or may become contaminated.
f. Check the markings on the standard sources andsee that the jigs are properly arranged in the case.
g. Perform a leak test (wipe test) (para 2-2) on all thesources to make certain that they are undamaged.
h. Replace the mask and the cushioning pad and closethe case,
2-2. Initial Checks and Services
NOTEA leak test must be performed immediatelyupon receipt of the AN/UDM-6 and at leastevery 3 months thereafter, while it is in use.
a. Perform the leak test as follows:(1) Five 1-inch smear papers (Whatman filter
papers or equivalent) are required. The smear papers aresupplied in a kit which is periodically replaced. Thesekits are available from Commander, US Army IonizingRadiation Dosimetry Center, ATTN: DRSMI-MCI-DC, Lexington, KY 40511 or from the CECOM SafetyOffice. They are also commercially available.
(2) With a ballpoint pen or china marker, numberthe smear papers consecutively. Key each smear paperto each item to be checked. For example, number thejigs from left to right I through 4. The number can bemarked on the case with a china marker. Number themask number 5. If necessary, this can be marked on themask with a china marker without affecting its proper-ties.
(3) Dampen the smear papers with water. Do notsoak them.
(4) Put on protective gloves.
WARNINGPlutonium 239 is DANGEROUS. Handle theAN/UDM-6 carefully. DO NOT TOUCHTHE RADIOACTIVE -STANDARD SOURCESURFACE. Avoid contact of objects, suchas tools, instruments, and calibrator com-ponents with the sources. Wear plastic or sur-gical protective gloves when performing leaktests and calibrations.

CHAPTER 2OPERATING INSTRUCTIONS
Section I. DESCRIPTION AND USE OF OPERATOR'S
CONTROLS AND INDICATORS
WARNINGJ
Use the AN/UDM-7C only under the guidance of an 4nstallationlactivity(local) Radiation Protection Officer and in accordaIlce with requirements ofChapter 5, Section IV, AR 40-5 and AR 385-11. k
Plutonium 239 (Pu239) is dangerous to living tissue. Small amounts of Pu239, when inhaled, in-
gested, or absorbed in open cuts or wounds, can cause serious illness or death. To avoid accident,observe the following:
* Use and store the ANIUDM-7C only in designated radiation con-trolled areas.
* Do not eat, drink, smoke, apply cosmetics, or store food stuffs,drinks, tobacco, or cosmetics where the calibrators are used orstored.
* Do not allow personnel with open skin wounds to handle orwork with the AN/UDM-7C without the approval of the medicalofficer and the (local) Radiation Protection Officer.
* Prohibit loitering in the area by unauthorized personnel.

ADJUSTABLE PROBE. POSITIONER. Aligns radiac probe over exposed source inprobe positioing well. The two L-shaped legs of the probe positioner can be ad-justed to fit the contour of the probe base by loosening two thumbscrews whichengage elongated slots in the legs, sliding the legs along the axis of the slots, andthen tightening the thumbscrews. The positioner will then be clamped to the edgesof the probe.
)
ATTENUATORS. Provide reduced radia-tion transmission levels when required.When an attenuator is used with the pro-be positioner, the attenuator* is placedin the milled groove and the probe posi-tioner is placed on top of the attenuator.

a. Leak Test (Wipe Test).
FNOTE1
A leak test is performed immediately upon receipt of theANIUDM-7C and at least every 3 months thereafter, whilein use.
WARNINGN
Plutonium 239 is dangerous to living tissue. Handle theAN/UDM-7C and components carefully; DO NOT TOUCHTHE SOURCE SURFACE. Avoid contact of objects, suchas tools, instruments, and calibrator components with thesources. Wear plastic or surgical gloves when performingleak tests and during calibration.
Use commercially available 1 inch smear ©©papers (What man filter papers orequivalent). A minimum of nine smearpapers will be rbquired. IF
Number consecutively one side of each smear paper and key the numbers toeach area, component, or calibrator to be smeared. Use ballpoint or chinamarking pen to number the papers.
* Dampen the smear papers with water. Do not soak them.
* Put on rubber or plastic gloves.
Smear the exterior surfaces sur;rounding the probe positioningwell (shaded area). One smearpaper should be enough.
CIE

TM 11-6665-247-10
Smear the interior surfaces of the source positioning shelf. Wrap a moistened smearpaper around the blunt end of a pencil or dowel and smear those surfaces which arenear the radioactive-coated surface of the source when the source is inserted into theshelf.
)
Smear the probe positioner, both attenuators, the tweezers, the inner surfaces of the ac-cessory drawer, and the inner surfaces of the carrying case cover. Use a separate smearpaper for each item.

* Position the probe of a calibrated radio set 1116 to 118inch above each of the dried papers and record themeter reading for each smear paper.
C5FNO-T-E
If the radiacmeter indicates 200 or more counts-per-minuteabove background for any single smear paper, considerthe calibration unserviceable and remove it from operationuntil the smear paper is evaluated with laboratory equip-ment. If the meter indicates less than 200 counts-per-minute, use the calibrator pending evaluation of the smearpaper.
Remove rubber or plastic gloves. Dispose as radioactive waste. (Refer to AR 385-11.)

b. Smear Paper Evaluation
Evaluate each smear paper using laboratory equipment capable of detecting 0.001 micocurle ofalpha contamination on the test sample. Record test results arid maintain these records for in-spection. If the test reveals the presence of 0.005 microcurie orImore of contamination, the usershall immediately withdraw the calibrator from use and reportthe condition through the Radia-tion Control Officer, (AR 385-11) to the licensee who will furnish disposition instructions andsubmit required reports to DA and NRC.
No maintenance or repair will be performed by the operator.The US Army Ionizing Radiation Dosimetry Center located atLexington-Bluegrass Depot Activity is the only authorizedfacility for maintenance or repair of the calibrator. Requestsfor maintenance or repair will be submitted to the radioac-tive material control point for coordination with CECOM andthe US Army Ionizing Radiation Dosimetry Center.
If a using installationlactivity does not have the proper laboratory equipment, the smear paperswill be processed as follows:
* Place the smear Oapers, each separated by a sheet of paper in a smallenvelope marked with the name and location of the user, the serialnumber(s) of the radioactive test sample(s) and the words: MAILROOM-DO NOT OPEN. Seal the envelope for forwarding.
" In CONUS, forward the smear papers for evaluation using official mailhandling channel to, Chief, US Army Ionizing Radiation DosimetryCenter, ATTN: DRSMI-MCJ-DC, Lexington, KY 40511.
" Commanders at overseas installations will comply with proceduresestablished by the responsible commander.
