RevistaMexicanadeFisica 5, 153-66 (1956) Data on radioactive rain, which were obtained by the gummed leaf nethod and by collection in a free surface of water are presented. The experimental methous are described. Some conclusions are obtained on the relative efficiency of the two methods and their relations to atmospheric precipitation. 2. Allen, J. S.

West VirginiaUniversityBulletin, Series 56, 55-57 (1957). Science 125, 1273-78 (1957). Measurements of the cst3? content of people and of food- stuffs indicate that this nuclide is unlikely to be a ; decisive factor in the long-term hazards from Weapons) 39 testing and reactor 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 logation. The average radiation dose received from Cs is one-twentieth of that received from natural radiopotassium and 1 percent of the average total dose from all natural sources. Because of the short biological half-life of cesium of about9ot0 days, it does not accumulate in the body as does Sr? The study of the distribution of Csl3/ 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. 4.
