| This document is part of a continuing effort by the Office of Radiation and Indoor Air and the Office of Superfund Remediation and Technology Innovation to provide guidance to EPA site managers and their contractors responsible for managing the cleanup of sites contaminated with radioactive materials. The document is an overview of radioanalytical methodologies that can be used for the identification and quantification of radionuclides likely to be found in soil and water at cleanup sites contaminated with radioactive materials. It is not a catalog of analytical methods, but rather is intended to assist project managers in understanding the concepts, requirements, practices, and limitations of radioanalytical laboratory analyses of environmental samples. It describes appropriate radioanalytical methodologies used to characterize environmental samples containing radionuclides, including screening methodologies and radionuclide-specific analyses and includes a primer on radiation physics and the basics of radiochemistry. |
