Film packs at specified locations in the foxholes produced
exposure readings such that the following conclusions could be drawn:
(1) a two-man foxhole located 1,000 yd or more from ground zero affords
good protection against gamma radiation emitted during the detonation
2,000 ft above ground of an approximate 2O KF atomic bomb, the exposure
being less than 224r at a 32-inch depth.
(2)
A one-man foxhole affords
better protection against gamma radiation than does a prone shelter or
a two-man foxhole, maximum protection being found at the side of the
foxhole nearest the burst.

CLOTHING DECONTAMINATION STUDIES AT DUGWAY PROVING GROUND.
John A. Pierce, Jr., Robert P, Beckelheimer, and
Frank 8S. Badger, 20 February 1952.
CONFIDENTIAL
Tests were undertaken to determine contaminability and
decontaminability characteristics of military fabrics with respect to
various RW contaminants. Eight different RW munitions were set up at 100-yd
intervals, with the fabrics and clothing to be tested located in regular
patterns dcewnwind from the line of munitions.
Test pieces were exposed
horizontally at a distance of 25 yd from each munition, and perpendicularly
at a distance of 45 yd.
These tests revealed that the working of the material (folds,
seams, etc.) is a significant contamination factor, while the nature of
the fabric appears to be the critical decontamination factor.
HBT and
wool uniforms have better contaminability and decontaminability
characteristics than sateen uniforms.
When made up into bags of like
size, rayon, nylon, and wool exhibit characteristics superior to sateen
and HBT.

FEASIBILITY STUDY OF SOLUBLE FILMS IN DECONTAMINATION OF
STRUCTURES.
Ralph E. Rexroad, June 1951.
CONFIDENTIAL-RESTRICTED DATA
Typical building-material surfaces were coated with certain
protective films and then contaminated with a solution of mixed fission
products.
These films, though soluble in alkaline solutions, are
insoluble in water, a property which makes them suitable for use on surfaces
exposed to rain.
-
in) contaminated, coated surfaces were subjected to low-
pressure (5 1b/sq in) hosing with an alkaline solution, this treatment
washing toth film and contaminant from the various materials.
