CESIUM-137 AND STRONTIUM-90 IN MILK
Cesium-137 and strontium-90 levels in liquid milk samples from Bombay and 27 other stations in India, and powder milk samples from Australia, Denmark, Holland, India, UK, and the USA were estimated since 1958. Cs/sup 137/ was estimated by gamma spectroscopy using a 10-channel scintillation spectrometer. Sr/sup 90/ levels were measured by chemical separation of strontium from samples of milk and measurement of beta activity on a low level beta counting instrument. The maximum and minimum levels of Cs/sup 137/ country-wide milk samples for the years 1959, 1960, and 1961 are 159.9 and spectively; the maximum and minimum levels of Sr/sup 90/ are 32.5 and 0.5, 8.8 and 0.3, and 44.3 and 0.5 mu mu C/g calcium, respectively. Cs/sup 137/ and Sr/sup 90/ contents of Australian and Indian milk powders are the lowest and of the same order, while the levels for the samples from UK are the highest. The results of the measurements were interpreted on the basis of the rate of fallout of the isotopes, seasonal effects, and other meteorological phenomena. (auth)
