PRELIMINARY INFORMATION ON STUDIES OF RADIOACTIVE RAIN. Revista mexicana de fisica 5, 153-66 (1956). Data on radioactive rain, which were obtained by the gummed leaf method and by col- lection in a free surface of water are presented. The experimental methods are described. Some conclusions are obtained on the relative efficiency of the two methods and their relations to atmospheric precipitation. . Allen, J. S. A-BOMB FALLOUT IN NORTHERN WESTVIRGINIA.

Science 125, 1273-78 (1957). Measurements of the Cs!*’ content of people and of foodstuffs indicate that this nuclide is unlikely to be a decisive factor in the long-term hazards from weapons testing and re- actor waste disposal. The amount of Cs'" now present in the population of the United States averages 0.006 microcurie and shows no marked dependence on geographic location. The average radiation dose received from Cs'*’ is one-twentieth of that received from natural radiopotassium and 1 per cent of the average total dose from all natural sources. Because of the short biological half life of cesium of about 140 days, it does not accumulate in the body as does Sr’. The study of the distribution of Cs'*" is being continued to furnish information on the mechanisms of the fallout process and provide a measure of the rate of fallout and of stratospheric storage. .
