Abstract
The radiochemical analysis of the so-called Bikini ashes which fell on a Japanese fishing boat, the No. 5 Fukuryu Maru on March 1, 1954, are described as of some 25 days after detonation of the bomb. The collected sample 10/sup 7/ counts/min.) was ignited and dissolved in 6N HC1, insolubles were filtered off, and the activity of small aliquots of the filtrate was measured. Total activity was estimated about 10/sup 6/ counts/min. Ru (10mg.) was added to the filtrate as a carrier, the acidity of solution was adjusted to 2N, H/sub 2/S was passed through to precipitate Ru as sulfide, and the precipitate was dissolved with HNO/sub 3/, H/sub 2/O, KMnO/sub 4/, and concentrated H/sub 2/O/sub 2/. The appropriate aliquot portion of the distillate was taken up in a counting dish and evaporated to dryness, the activity was measured and found to be 1.5 x 10/sup 5/ counts/min.
