SOURCE (USA) PUB. DATE (YYMMDD ) CLASSIF. LEVEL T EXT ABSTRACT CA 560113 Unclassified Certain fallout samples from Operation Castle were retained for decay rate measurement. The exponent of the equation Af{sub t} 801. KEYWORD(S) San Francisco, = A{sub 0} t{sup -k} was evaluated from appropriate log-log plots and found to be in the range 1.1 to 2.03. This range of values is larger than that expected from thermal-neutron fission. CASTLE/fallout ;FALLOUT/decay ;CASTLE; FALLOUT; DECAY; IONIZATION CHAMBERS; GAMMA RADIATION Item 51 150. 110.
