Abstract

This report provides updated information on the default parameter values and parameter distributions contained in the RESRAD family of codes since the release of the probabilistic RESRAD-ONSITE Version 6.0 (formerly called RESRAD 6.0), RESRAD-OFFSITE Version 2.0, and RESRAD-BUILD Version 3.0 (Yu et al. 2000, 2007). This report also discusses changes made in the family of RESRAD codes since 2002. All three codes are pathway analysis models designed to evaluate the potential radiological dose incurred by an individual who lives at a site with radioactively contaminated soil or who works in a building containing residual radioactive material.

In this report, probabilistic analyses are performed to evaluate the effect of new parameter values and distributions on radiation exposures associated with common exposure scenarios using new information such as updated dose conversion factors and transfer factors. Based on the probabilistic analyses and the new information available on default parameter values, parameter distributions are either updated if additional data is available or developed if distributions for new parameters are identified. Appendix A of this report provides the default parameter values and parameter distributions for RESRAD-ONSITE Version 7.2, RESRAD-OFFSITE Version 4.0., and RESRAD-BUILD Version 3.5. The exposure scenarios used to evaluate the effect of new parameter values and distributions includes the following: Resident Farmer scenario for the RESRAD-ONSITE code; Building Occupancy scenario for RESRAD-BUILD code; and, Offsite Resident scenario via Water Transport and Offsite Resident scenario via Air Transport for the RESRAD-OFFSITE code. For the RESRAD-ONSITE and RESRAD-BUILD codes, newly developed template files are presented to simulate the Resident Farmer and Building Occupancy scenarios as described in NUREG/CR-5512 (Kennedy and Strenge 1992) and NUREG-1757 (NRC 2006). Appendix B provides the results of the probabilistic analyses for the above exposure scenarios as well as the selection of input parameters, deterministic results and regression analysis for each exposure scenario. Appendix C provides the parameter distributions and supporting information available for use in RESRAD-ONSITE Version 7.2, RESRAD-OFFSITE Version 4.0., and RESRAD-BUILD Version 3.5.
