Abstract Seasonal variations in the concentration of long-range fall-out material are discussed, and various meteorological conditions which may account for a spring maxima are reviewed. Data are tabulated from measurements of Sr/sup 9// sup 0/ in rain samples collected in Great Britain during 1960, specific concentrations of Rh/sup 1//sup 0//sup 6/, Sb/sup 1//sup 2//sup 5/, Cs/sup 1//sup 3//sup 7/ and Ce/sup 1//sup 4//sup 4/ in fallout samples, and the fission yield for various types of fission. From calculations based on available information on the dates of megaton explosions, it is concluded that the majority of the fall- out material originated from American and British equatorial tests of 1958. Discrepancies in the yield of Sb/sup 1//sup 2//sup 5/ and Rh/sup 1//sup 0//sup 6/ were found. It is concluded tha t these discrepancies may be explained if, in addition to the 14-Mev fission of U/sup 2//sup 3//sup 8/, other fission processes are involved. (C.H.) .
