This report is the third of a three-volume tabulation of internal radiation dose conversion factors for man for radionuclides of interest in environmental assessments of nuclear fuel cycles. This volume provides an updated summary of estimates of committed dose equivalent for 142 radionuclides considered in the previous two reports. Intakes by inhalation and ingestion are considered. The International Commission on Radiological Protection (ICRP) Task Group Lung Model has been used to simulate the deposition and retention of particulate matter in the respiratory tract. Results corresponding to activity median aerodynamic diameters (AMAD) of 0.3, 1.0, and 5.0 ..mu..m are given. The gatrointestinal (GI) tract has been represented by a four-segment catenary model with exponential transfer of radioactivity from one segment to the next. Retention of radionuclides in systemic organs is characterized by linear combinations of decaying exponential functions. Fifty-year dose commitment per microcurie intake of each parent nuclide is given for 22 target organs including contributions from specified source organs plus the systemic activity residing in the rest of the body; cross irradiation due to penetrating radiations has been incorporated into these estimates. A separate tabulation of effective dose equivalent for all 142 radionuclides is provided also; this quantity, as defined by ICRP Publication 26, provides an indication of the overall health risk resulting from a radionuclide exposure. 22 refs., 6 tabs.
