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. The objective of phase 1 of the project was to demonstrate through calculation that adequate models and support data existed or could be developed to allow estimation of realistic doses to individuals from releases of radionuclides to the environment that occurred as long as 45 years ago. This paper presents a summary of the results calculated for phase 1 of the project. These results were made public in July of 1990. The phase 1 study area for the air pathway covers the ten countries nearest the Hanford Site. This area was selected to encompass populations nearest the releases and therefore most likely to have been in the path of the highest concentrations of radioactive materials. The radionuclide likely to have contributed most to doses to off-site populations was determined to be {sup 131}I. It was estimated that the 1944-1947 period accounts for > 90% of the {sup 131}I released since start-up of the facilities. The phase-1 air release time period was therefore selected to encompass this period. Pathways of exposure included external exposure via submersion and groundshine, inhalation, and ingestion of crops and animal products, particularly milk.
