The U.S. Transuranium Registry report on the 241Am content of a whole body. Part I: Introduction and history of the case.

The first whole-body analysis of the U.S. Transuranium Registry was initiated in 1979. The donor was a 49-yr-old male Caucasian radiochemist who died of metastatic malignant melanoma. The donor had a recognized, longstanding 241Am internal deposition first identified in a routine urine sample in 1958. A summary of the clinical and postmortem findings is presented with the chronologic sequence of the procedures.
