Title: Radiological Assessment of Releasing Scrap Metal from Nuclear Facilities

Abstract

Large quantities of scrap metal are generated during the extensive worldwide decontamination and decommissioning of nuclear facilities and, to a lesser extent, during the normal operations of these facilities. To evaluate the radiological impacts of releasing potentially contaminated metals to the general environment, the U.S. Environmental Protection Agency (EPA) performed an exhaustive analysis of the release and recycling of carbon steel scrap. Further assessments were performed of the clearance and recycling of aluminum and copper scrap. The aim of the analyses was to calculate the annual dose and the lifetime risk of cancer to the reasonably maximally exposed (RME) individual, normalized to the specific activity of a given radioactive contaminant in the scrap, from 1 yr of exposure. These results, presented as a set of tables that list the normalized doses and risks to the RME individual for each of 40 radionuclides that are potential contaminants of the three metals, can be used to assess the potential health effects of releasing scrap with a given level of contamination. This report describes the analysis and gives a summary of the results.
