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 for radiochemical contaminants during homeland security events. Methods have been selected for each isotope and for each sample type that potentially may need to be measured and analyzed when responding to an environmental emergency.
Please note: SAM provides guidance for selecting radiochemical methods that have a high likelihood of assuring analytical consistency when laboratories are faced with a large scale environmental restoration crisis. Not all methods have been verified for the analyte/sample type combination listed. 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 Web site. 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. After locating the analyte of concern, continue across the table to identify the appropriate determinative technique (e.g., alpha or beta spectrometry), then identify the appropriate qualitative and/or confirmatory method for the sample type of interest (drinking water, aqueous and liquid phase, soil and sediment, surface wipes, and air filters) for the particular analyte. See: Radiochemical Methods Query.
UPDATE: In April 2013, EPA published three rapid methods for analysis of soil samples. The methods should be used in lieu of methods that are currently listed in SAM for qualitative analysis of the following isotopes in soil samples:
- americium-241
- plutonium-238
- plutonium-239
- radium-226
- strontium-90
- uranium-234
- uranium-235
- uranium-238
The rapid methods are provided and summarized in the following:
- Addendum for: Rapid Method for Sodium Carbonate Fusion of Soil and Soil-Related Matrices Prior to Strontium-90 Analyses for Environmental Remediation Following Radiological Incidents
- Addendum for: Rapid Method for Fusion of Soil and Soil-Related Matrices Prior to Americium, Plutonium, and Uranium Analyses for Environmental Remediation Following Radiological Incidents
- Addendum for: Rapid Method for Radium in Soil Incorporating the Fusion of Soil and Soil-Related Matrices with the Radioanalytical Counting Method for Environmental Remediation Following Radiological Incidents
Below is a list of all selected radiochemical methods with a link to their method abstract. 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.
