The present study is bansd on the information which has been revealed
concerning the extent of contamination in the fall-out area of a 15 megaton
hydrogen bomb (Bikini test, March 1, 1954). On the basis of these data the
protection afforded by bunkers and house cellars against the gamma ’
radiation of fall-out is estimated. In addition, the optimal length of stay
in shelters.is calculated, i.e., the time at which the shelter and the
fall-out area must be abandoned if the radiation dose is to be kept at a
minimum. The results obtained point out the necessity of decontaminating
traffic routes in fallout areas. (auth)

BS> Soil samples from Rongelap Atoll were analyzed for radionuclide
content. Using ion-exchange methods, a detailed study was made of a soil
sample collected in a bird nesting area at Kabelle Island in July 1957.
Two
radioisotopes, antimony-125 and europium-155, not previously reported in
samples from the Pacific Proving Ground were found and their identity was
verified by radiochemical precipitation techniques. The radionuclides
contributing most of the radioactivity were Ce/sup 144/-Pr/sup 144/ and
Fe/sup 55/,
a non-fission product. Other radionuclides present in much
smaller amounts included Ru/sup 106/-Rh/sup 106/, Sr/sup 90/-Y/sup 90/,
Cs/sup 137, Mn/sup 54/, Co/ sup 6 0/, Zr/sup 95/-Nb/sup 95/, Co/sup
57. (auth).

Radiobiological analysis of the reef fishes of Rongelap and Ailinginae
Atolls indicated that a recontamination of the area occurred in 1956. Gross
levels of beta activity in muscle tissue ranged from 0.016 to 0.038
