A new method for the localization of 239Pu in bone is described. The method, which is based on semi-automatic digitization of neutron induced autoradiographs, allows the 239Pu to be localized with respect to bone surfaces with an accuracy of +/- 2 micron. Results are presented for the distribution of 239Pu in the central lumbar vertebrae of female CBA mice at 24 h post-injection.
