di rect contact. The radiation control line should be
adjusted depending on the extent of ground contamination
detected. If no ground contamination is detected during the
radiation survey of the area, proceed with the radiological
survey of the vehicle. However* should ground contamination
be detected, the areas should be marked off utilizing NBC
contamination marking kit for later decontamination efforts.
The radiation contamination control line need not be a
circle, but may take on the shape of the detected ground
contamination.
3. Survey the outside of the tank for DU contamination with
an AN/PDR-54, AN/PDR-60, AN/PDR-56F radiac meter (IM-16OF/PD
R-56 and its accompanying radiac probe (DT-224B/PDR-56F [main
probe]), or an equivalent instrument if the surface of the
Tank is dry. The probe must be held as close to the surface
as possible without coming in contact. However, if the
surface being surveyed is wet or covered with grease or dirt,
there exist a condition of alpha self-absorption and an
AN/PDR-27 with the beta shield open, an AN/VDR-2 (IM-243
meter and DT-616 probe) or equivalent instrument, is to be
used. If no contamination is detected, it will be necessary
to decontaminate a pathway on the vehicle to gain access to
the interior. Swipe/wipe the surface of the vehicle along
the proposed pathway where contamination is detected. The
swipe samples should be taken with appropriateswipe paper,
such as Whatman filter paper. The same instrument being used
to survey the tank should be used to analyze the swipe paper.
If the appropriate swipe paper is not available, then take
swipes with a paper towel, cloth, etc. Under these
DR-27 with
the beta shield open, AN/VDR-2 (IM-243 meter and DT-616
probe), or an equivalent instrument. If contamination levels
are detected, the surface area that is representative of that
swipe sample will have to be cleaned until the removeable
surface contamination levels are at least reduced to those
levels listed for vehicles in uncontrolled areas in TB 9-
1300-278, appendix F. Some material used for wipes will not
pick up metal fillings, metallic dust, etc. The only method
to detect the presence of this kind of contamination is to
use tape.
4. If instrument surveys indicate the presence of
contamination but the swipe/wipe are negative, press a piece
of masking, friction, or adhesive tape onto the area and
analyze it with the AN/PDR-27, AN/VDR-2 or equivalent
instrument. If the tape is contaminated, this indicates the
presence of small pieces of metal and or metallic dust.. Make
sure this material is removed before declaring the pathway
free from contamination.

HIAI tanks that contain Depleted Uranium (DU) armor can be
