SAM Radiochemical Methods Query

The web page you are viewing requires JavaScript.  This web page is an enhancement to provide users of the Selected Analytical Methods for Environmental Remediation and Recovery (SAM) - 2017 document with the ability to search the analytical methods it contains. If you are unable to view the information on this Web page, the methods may also be found in the PDF version of the document.

See: Selected Analytical Methods for Environmental Remediation and Recovery (SAM) - 2017.

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 discussed in this section should be addressed to the appropriate contact(s).  See SAM Technical Contacts.

Note: Please see SAM Updates for important information about updates to SAM methods that may supersede methods listed in the SAM document and the results of this query.

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 ( and accommodations will be made.
