Supplementary Documentation for Environmental Impact Statement Regarding the Pantex Plant: Agricultural-Food-Chain Radiological Assessment

摘要

This report documents work performed in support of preparation of an Environmental Impact Statement regarding the Department of Energy's (DOE) Pantex Plant near Amarillo, Texas. Soil, water, vegetation, and beef cattle were sampled on the Pantex Plant and the general experimental treatments analyzed for a feedlot experiment. The chemical and radiochemical methods used for analyzing these samples at the Los Alamos National Laboratory are discussed for each sample type. The radiation levels found in water, soil, range vegetation, sorghum, and beef cattle from sampling on and near the Pantex Plant are compared to natural background levels. Their significance is interpreted as radiation doses from ingestion of meat. (ERA citation 09:038436)
