METABOLIC BEHAVIOUR OF $sup 137$Cs-$sup 137$mBa IN THE LACTATING GOAT
Investigations on the metabolism of Cs/sup 137/ in the lactating goat demonstrated that the biological half-time for removal of Cs/sup 137/ from the body was about 2 to 3 days. At steady state, about 7% of the daily dose of ingested Cs/sup 137 was secreted daily in milk, about 40% in the urine, and about 40% in the feces. The Cs/sup 137//K ratio in milk was 1.4 based on a dietary Cs/ sup 137//K ratio of unity. The mammary gland did not differentiate between Cs/ sup 137/ and K, and the organ of highest concentration was kidney, with values 1.5 times that of muscle and other soft tissues. The Ba/sup 137m/ daughter metabolically dissociated from its Cs/sup 137/ parent in vivo so that the gamma activity of the whole blood of the living animal was 5.5 times that as usually determined. These and other findings are discussed and reference made to differences in Cs/sup 137/ metabolism between ruminants and non-ruminants. (auth)
