Tissue studies of persons with intakes of the actinide elements: the U.S. Transuranium and Uranium Registries.
For more than three decades, the United States Transuranium and Uranium Registries (USTUR) have studied the biokinetics, dosimetry, and biological effects of plutonium, uranium, and americium through voluntary postmortem tissues from persons with known intakes. Radiochemical analyses of tissue obtained at autopsy have shown that plutonium and americium have different biokinetics and an appreciable deposition in the soft tissues of the body as well as the known depots in skeleton and liver. Studies of whole-body Thorotrast donors to the USTUR indicate that commonly accepted risk coefficients for alpha induction of bone sarcoma may be too high while those for leukemia are a factor of six too low. This review considers these and other major contributions of the USTUR.
