THE OCCURRENCE OF ANTIMONY-125, EUROPIUM-155, IRON-55, AND OTHER RADIONUCLIDES IN RONGELAP ATOLL SOIL

Technical Report ·
OSTI ID:4311911
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).
