A Hanford worker received an intake of /sup 241/Am by skin absorption and inhalation which was later evaluated to be in excess of 1 mCi. The skin was the main pathway for introduction of /sup 241/Am into the body; however inhalation was also a significant pathway. Intensive DTPA therapy prevented 99% of /sup 241/Am which entered the body stream from being deposited in the internal organs. Retention and distribution of /sup 241/Am in various internal organs and tissues was determined from sequential measurements in vivo using several arrangements of externally located scintillation detectors. The organ and tissue retention and distribution have been followed for over 5 years. Excretion patterns and estimates of radiation dose to the lung, liver, bone, and skin are described.
