Radiation dosimetry of 204Bi- and 206Bi-citrates.
The absorbed-radiation doses from 204Bi- and 206Bi-citrates to humans are calculated from  available nuclear and biologic data in order to evaluate the relative radiation risk of these radionuclides. The calculations reveal that the radiation dose to the kidneys is reduced by a  factor of 8 if 204Bi replaces 206Bi. This reduction suggests that 204Bi should be investigated further as a possible soft-tissue scanning agent.
