This report reviews dosimetry models for estimating the absorbed dose from external and internal exposure to radionuclides. Important modeling parameters and assumptions are described. Recommendations for the dosimetry data to be used in the MELCOR health and economic consequence model are made. For estimating the dose from cloudshine and groundshine, the models for external exposure developed by Kocher are recommended. The ICRP-Publication 30 models and metabolic parameters are recommended for estimating the dose from radionuclides deposited internally via inhalation and ingestion. Dose conversion factors calculated with these models for a variety of radionuclides, clearance classes, particle sizes and integration periods were obtained from Oak Ridge National Laboratory for use in the MELCOR health and economic consequence model. Sources and magnitude of uncertainty in dose factors were evaluated. Recommendations are made for assessing the uncertainty in estimated consequences due to uncertainty in dose conversion factors. 45 refs., 4 figs., 5 tabs.
