with maximums of 204 and 356 micromicrocuries per gram, respectively. Gross beta counts of some Guam and Palau samples prior to the arrival of the Hardtack fallout indicate the presence of radionuclides from prior test series. Gamma-emitting nuclides other than naturally occurring potassium-40 included, in order of abundance, cobalt-57, cobalt-60, manganese-54, ceriuml44, zinc-65, and silver-110m. The greatest value was 2, 30Q micromicrocuries per gram of wet weight for clam kidney (Tridacnd). The occurrence of silver-110m in the liver of the spiny lobster was of special interest because it is a previously unreported fallout nuclide and so far ‘ has been detected only in spiny lobster.

Report Language: English Contract No.: AT(11-1)-1254 Data on the biological effects of radiation were accruod from laboratory and field animal tests, clinical therapy, radiation accidents, the accidental exposure of the Marshallese population, and the exposure of the populations of Hiroshima and Nagasaki to radiation. Symptoms and effects studied includod chromosome damage causing hereditary changes, cancer, debilitating effects, and shortening of the life span. induction of The data will be used in the preparation of a mathematical model of the effects of radiation dose rate on life span.

Sixty-four inhabitants of Rongelap, 105 nautical miles from the detonation, received an estimated dose of 175 r of whole-body the skin sufficient to result in beta burns, radiation, contamination of and slight internal absorption
