FIELD OPERATIONS
In cooperation with other projects of Program 37, seve’ u groups of rabbits were trans-
ported to and trom predetermined locations on the predicted path of fall-out by members of
art
Project 37.3. Two additional groups of animals were employed for control purposes: One was
a
kept at the laboratory in Mercury; the other was transported to and from the fall-out areas to
evaluate the amount of exposure during transport only. The preshot placement of experimental
and control groups of rabbits is given in Table 2.1.
At each fall-out station, facilities and equipment for measuring air-borne radioactivity,
aoil contamination, plant contamination, particle-siz~ distribution, and accumulated external
gamma-radiation exposures were provided and operated by Projects 37.1 and 37.2. Chemical
dosimeters were supplied by Project 39.6,
