This report provides radiation dose modeling analysis supporting the technical derivation of the authorized limits for selected portions of the Hanford Reach National Monument (HRNM). The RESRAD (Yu et al. 2001) computer program was used as the calculational model. The goal of this effort was to produce authorized limits, in units of pCi/g in soil, for the HRNM that would result in radiation doses less than 25 mrem/y, in compliance with the requirements of the U.S. Department of Energy (DOE).
