Reduction in exposure doses by adjustment ofliving routines as a function of
time after detonation and radiation intensity
Reduction in absorbed doses to animals and humans by storage and allocation
ofcontaminated foodstuffs
Ingress of fallout particles into shelter spaces through openings and ventilation systems and effect on the exposure dose or on the shelter protection
factor
Verification of shielding provided by specially designed shelter-entryway
configurations
Proof tests of operational radiological-defense systems and overall effectiveness evaluations
The individual project titles, as parts of the field-test fallout
program for the Small Boy shot, are listed in Table 5. The projects,
with a few exceptions, were very successful in meeting their individual
objectives. This general success was due, first, to the detailed development of the project experimental designs on the part of the
project leaders and the efforts of all the project personnel in carrying
out the work and, second, to the favorable winds that carried the fallout
over the established station array. It should be noted that projects
involving the design and testing of sampling equipment for possible use
in future programs were included in the program.
