Experiments on the metabolism of certain fission products in dairy cows
Dairy cows have boen fed with separated carrier free I/sup 131/, Sr/sup 89/, Te/sup 132/ and Ru/sup 106/. The amounts of these isotop es recovered from the milk, urine and feces, and their rates of secretion and excretion, have been measured; estimates have also been made of the amounts retained in the body. Nineteen administrations of iodine have been made, twelve of strontium, five of tellurium and one of ruthenium. Wide variations in the amounts of I/sup 131/ and Sr/sup 89/ secreted into the milk have been observed. These were partly due to the variations in milk yield. Similar experiments have been carried out with fission products collected from trials of atomic weapons. There was no apparent difference between the metabolism of the fission products from the two sources. (auth)
