| Popis: | The present permissible occupational levels for the bone-seeking radionuclides are tied to that for 226Ra, which has served for several decades as the prime standard. To establish these permissible levels and that of 226Ra at certain points, observable effects have been related to carefully determined body content of the radionuclide under consideration. This has been done by many investigators with various species of experimental animals for many of the bone-seeking radionuclides, and a scale of relative radiotoxicities has been derived. The experimental approach is not possible in man. However, for the case of 226Ra effects in man we have attempted to derive as much information as possible from a rather large group of persons in midwestern United States who acquired a body burden of 226Ra approximately forty years ago. From these data we have related 226Ra body content to the incidence of skeletal and other rare tumors arising in the tissues lining the mastoids, paranasal sinuses, and oral cavity on the... |
