The assessment of the dose that could be received by a member of the public due to an accidental release of airborne radioactivity from a nuclear power plant is dependent upon the release, dispersion, and dosimetric calculation models utilized. This article describes a study that was performed to determine the impact of changing dosimetric models from those of ICRP-2 to those of ICRP-26. Fourteen release scenarios were analyzed for each of six generic reactor sites. The equations used to model atmospheric transport, aerosol dispersion, and radionuclide deposition are described along with the methods used to analyze short-term and long-term exposure. The results of the study indicated that predicted doses for accidents would decrease from the current critical organ doses (ICRP-2) if ICRP-26 methodology were to be implemented; however, the magnitude of the change would be dependent upon the postulated source terms.
