75684-The evaluation of radionuclide and metal contaminants in the groundwater at DOE sites is typically done offsite using plasma mass spectroscopy or optical emission spectrometry. These analysis techniques are not suitable for automated field use because they require control gas or vacuum to function. A simple, robust, non-destructive analysis technique is required for in situ remote monitoring applications. This project will develop a grazing-incident-monochromatic micro x-ray fluorescence (GI-MMXRF) analysis system, which, when combined with an innovative dried spot sample preparation system, will offer high sensitivity and automated sample preparation. The combination of low power GI-MMXRF and ink jet printing technology makes this an approach that can be readily adapted for remote monitoring or in situ applications. In Phase I, a doubly-curved crystal optic will be designed for use with an existing x-ray fluorescence analysis setup. A laboratory setup of the sample deposition system will be used to evaluate spot size and GI-MMXRF detection limits with various film substrates. The feasibility of a field-deployable system will be evaluated. Commercial Applications and Other Benefits as described by the awardee: In addition to the remote monitoring of radionuclides and metals in groundwater at hundreds of DOE sites, the technology also should draw interest from industries and government agencies concerned with the monitoring of groundwater and groundwater remediation.
