Response to a commentary by Makhijani et al. (2010) on a research report by Delistraty et al. (2010)

摘要

The primary contribution of our analysis was to demonstrate the benefit of using measured environmental data when available, rather than modeled data, to improve the quality of pathway analysis within a risk assessment framework. Historically, radio-nuclide tissue concentrations in fish and wildlife used in risk assessment at the Hanford Site have been estimated from environmental transport models rather than determined from environmental sample data. Common models used at Hanford (e.g., RESRAD) are not equipped to estimate radionuclide concentrations in fish inhabiting a fast flowing and large river nor in wildlife ranging over a heterogeneously contaminated environment.
