Rain water has been collected systematically from 20 places in various latitudes and analysed for Sr/sup 89/ Sr/sup 90/ and Cs/sup 137/ produced by nuclear test explosions. A few snow samples from polar regions have also been included. The present report extends the results already published to cover the period up to mid-1958. The total deposition at a typical station in the U.K. during the 12 months ending April 1958 was 2.6 mc/km/sup 2/ compared with 2.55 mc/ km/sup 2/ in the preceding 12 months. More extensive evidence has been obtained that in the limited area of the U.K. the total deposition over a period appears to be proportional to the local rainfall. The rate of deposition in the U.K. during the four months of May to August 1958 was considerably greater than that during the corresponding period in previous years. It is thought that part of this increase is due to the rainfall which was some 1.7 times that during the corresponding peried in the three previous years. The measurements continue to support the observations in the earlier repont regarding the dependence of fall- out on latitude and the marked seasonal variation. (auth)
