Selection of Dominant Radionuclides for Phase 1 of the Hanford Environmental Dose Reconstruction Project

Description: The objective of the Hanford Environmental Dose Reconstruction (HEDR) Project is to estimate the radiation dose that individuals could have received as a result of emissions from nuclear operations at Hanford since their inception in 1944. A vital step in the estimation of radiation doses is the determination of the source term,'' that is, the quantities of radionuclides that were released to the environment from the various Hanford operations. Hanford operations have at various times involved … more

Comparison of computer codes and inputs used at DOE sites to model intrusion scenarios

Description: Scenarios and computer codes used to evaluate intrusion scenarios at different DOE sites are compared and discussed. The purpose of the comparison is to identify differences in the approaches and areas where approaches could be made more consistent without ignoring the need to consider legimate site-specific differences, The comparison is comprised of two steps: (1) benchmarking of CENII and PATHRAE (the two most commonly used codes at DOE sites), and (2) comparison of assumed values for select… more

Radiation Doses From Hanford Site Releases to the Atmosphere

Description: Radiation doses to individuals were estimated for the years 1944-1992. The dose estimates were based on the radioactive-releases from the Hanford Site in south central Washington. Conceptual models and computer codes were used to reconstruct doses through the early 1970s. The published Hanford Site annual environmental data were used to complete the does history through 1992. The most significant exposure pathway was found to be the consumption of cow`s milk containing iodine-131. For the atmos… more
