Measurement of Caesium-137 in Milk
Samples of liquid milk from Bombay and twenty-seven other stations in India, and imported powder milk from Australia, Denmark, Holland, U.K., and the United States were measured for their cesium-137 and potassium-40 contents. The average cesium-137 content of Bombay milk was 9.38 μμ c per g potassium for the year 1958, 18.26 μμ c per g of potassium for 1959, and 14.71 μμ c/g potassium for the first 2 months of 1960. The increase in the average level of cesium-137 by a factor of 2 during 1959 was attributed to the accelerated fall- out rate following the large number of tests conducted during the autumn of 1958. The cesium-137 content in the Australian powder milk was found to be about the same and in the European powder milk about two or three times that in the Indian powder milk. There are large variations in the levels of cesium-137 in different samples from India including Gangtok (Sikkim State). The values range from 2.79 to 159.9 μμ c per g of potassium, the highest value being for Gangtok.
