Reconstruction of dose equivalents to the public from the sup 60 Co Irradiator Facility at the Laboratory for Energy-Related Health Research
Because of the uncertainties associated with the dose equivalents received by the public, the DOE has tasked Environmental Management Operations (EMO), as part of the LEHR Environmental Restoration project commissioned by DOE, to reconstruct the dose equivalents received by the public adjacent to the LEHR site. The purpose of this study was to determine the potential radiation dose equivalents received by individuals in publicly accessible areas and to provide estimates of the associated risks to these individuals from the outdoor irradiations. EMO has reconstructed the radiation dose equivalent rates to the offsite areas using actual environmental radiation monitoring data augmented by Monte Carlo computer modeling of the radiation dose equivalent rates where necessary. This report describes the irradiator and adjacent areas, available environmental radiation data, the computer modeling and dose equivalent rate projections, occupancy determinations, and reconstructed dose equivalents. A risk factor is estimated for each of the dose equivalents calculated for the public. Traditional units are used throughout this report rather than SI (metric) units for reasons of clarity. 4 refs., 3 figs., 6 tabs.
