QUANTITATIVE MICROSCOPIC STUDIES OF THE DISTRIBUTION AND RETENTION OF PU-239 IN THE ILIUM OF THE FEMALE CBA MOUSE

Three month old female CBA mice were injected with 50 nCi kg-1 body mass of minimally polymeric 239Pu-citrate and killed at 24 hours, 10 days, 1 month and 3 months after injection. The distribution of 239Pu in the ilia of these mice was analysed using neutron-induced autoradiography of bone sections together with computer-based methods of data reduction. Results of these investigations demonstrate that while 239Pu is initially localized on bone surfaces, by 3 months after injection it is fairly uniformly distributed throughout mineral bone and its included marrow. © 1979 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
