Environmental Measurements Laboratories

This inter-laboratory cross-check program provides blind samples at environmental levels on a quarterly basis at concentrations that permit an evaluation of your analytical accuracy. The table below summarizes sample matrices and radionuclide combinations routinely available on a quarterly basis. Gamma-ray emitters include mixed-activation products with half-lives greater than seven days. Activity listed is per radionuclide. Contact Analytics for information on special orders and custom configurations.  There is a minimum of four samples per shipment. An additional fee will apply for less than 4 items per shipment.

Reporting Procedures

Sample price includes a comparison report listing our assigned value and the laboratory’s value which may include different detectors, shelves, etc. Upon data submission to our web portal, you will receive a report immediately. The known values along with client values are tabulated with the ratios of the known to reported values. Since data quality objectives vary among laboratories, no pass/fail criteria are used unless requested in advance.
