Abstract
Experiments were performed to study the internal transport and biological availability of radioactive lead that could be produced and released in certain types of nuclear cratering events, especially lead 203 and lead 210. A lactating dairy cow was used for the metabolic experiments, and a calf was used for the tissue distribution study. Urine, feces, blood, and milk samples from the cow were analyzed for each 24 hour period. Blood plasma and representative organs and tissues were removed from the calf and analyzed. Results showed a total recovery of 94.768% of the /sup 203/Pb in the feces, urine and milk of the cow by 144 hr. Approximately 85% was recovered in the feces in the first 48 hr. The total secretion in urine during 144 hr. was 0.173%, while the total secretion in milk was 0.190. These results reveal the slow, incomplete absorption of lead from the digestive tract. In the calf the tissue distribution of the absorbed lead shows that the erythrocytes represents the largest pool of lead in respect to recovery value. The tissue data confirm the known pattern of distribution of inorganic lead in soft tissues, with the highest concentrations in the liver and kidneys.
