Abstract
The authors have tried, during the radioactive period corresponding, to the nuclear tests of the autumn 1961, to follow under natural conditions the contamination of a herd of cattle made up 9 cows and 7 calves. The observations concern I{sup 131}, which was studied in particular, and the mixture of fission products. As far as the excretion of iodine in milk is concerned, the equilibrium is established slowly and the amount found in the milk is about 1 per cent of the daily intake. This figure is lower than those based on experimental studies (given in the literature). For the mixture of products, only a small number of elements is metabolised. The fraction found in 1 kilo of liver is about 5 x 10{sup -5} of the amount of Zr-Nb taker up per day, and about 4 x 10{sup -4} of the daily intake of Ru. These elements are not found afterwards in muscle.
