skin bone and muscle having successively lesser amourts. This relationship
prevailed throughout the period. The rate of decline was greatest during
the first 100 days, with a loss of 90% of the radioactivity during the
period. Studies were made on the varlation of total radioactivity in the
tissues and species, on comparisons of the amount of radioactivity in the
species and in their food, smd on comparisons of the decline of
j
radioactivity during the period with the decay of radioactivity ih tissues
collected soon after the shots. (auth)

This preliminary study conducted at the Bikini Atoll investigated the
variation of salt concentration in the first 300 ft of atmosphere by
collection on specially developed silver dichromate reagent films. For a
10-knot wind maximum concentration appeared to exist at 50 to 75 ft above
Mean Low Water Springs, with the possibility of a second maximum somewhere
ahove 300 ft. Preliminary sine-frequency counts showed a bimodal
distribution of salt nuclei with maximum at 5 and 12 microns.
