Mar. 5, 1957 Journal Announcement: NSAIS3 Availability: NTIS Document Type: Repart Language: English Contract Ne.: W-28-094-ENG-33 The fouling growth on a beat frame that had been mecred in Bikini Lagoon from July 15 to Aug. 28, 1947, was counted fer activity. This material, composed mostly cf a hydroid belanging to the family Flumularidae, had concentrated active materials exceeding the activity feund in the water many times. (W.D.M.)

Primary Report No.: UWFL-5é Journal Announcement: NSAi3 Availability: NTIs Document Type: Reppert Language: English Contract New: AT(45-1)540 BS> Sail samples from Reongelap Atcll were analyzed for radionuclide content. Using ion-exchange methads, a detailed study was made of a soil sample collected in a bird nesting area at Kabelle Island in July 1957. Two radioisotopes, antimeny-125 and eurcpium-155, net previously reported in samples from the Pacific Proving Ground were found and their identity was verified by radiochemical precipitation techniques. The radionuclides centributing most af the radioactivity were Ce/sup 144/-Pr/sup 144/ and Fe/sup S5/, a non-fission preduct. 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 O/, 2r/sup 95/-Nb/sup 95/, Co/sup 57.(auth).
