Environmental Sampling and Analytical Methods (ESAM) Program

SAM Radiochemical Methods

Selected Analytical Methods for Environmental Remediation and Recovery (SAM) provides a list of analytical methods to be used in analyzing environmental samples and outdoor building materials for radiochemical contaminants following a homeland security incident. Methods have been selected for each isotope and for each sample type that potentially may need to be measured and analyzed.

Please note: SAM provides guidance for selecting radiochemical methods that have a high likelihood of assuring analytical consistency when laboratories are tasked with analyzing samples following a large scale radiological or nuclear contamination incident. Although the majority of methods have been validated for the analyte/sample type combination for which they have been selected, validation is still needed for a few of the methods that have been selected for analysis of vegetation. Please refer to the specified method to identify analyte/sample type combinations that have been verified. Any questions regarding information for radiochemical analytes and/or methods should be addressed to the appropriate contact(s) listed on the Technical Contacts page of this website. See: SAM Technical Contacts.

To determine the appropriate method that is to be used on an environmental sample, locate the analyte of concern using the Radiochemical Methods Query page. The SAM query provides access to summary information, extracted from the selected methods. Each method summary contains a table identifying the contaminants in SAM to which the method applies, a brief description of the analytical method, and a link to or source for obtaining a full version of the method. The full version of the method should be consulted prior to sample analysis. See: Radiochemical Methods Query.

Below is a list of all selected radiochemical methods. Due to the complexity of some tables and graphics, some of our information is not amenable to a screen reader. If you have trouble accessing information contact Kathleen Nickel (nickel.kathy@epa.gov) and accommodations will be made.

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
