Hess, E. AND P. Splichal. ENVIRONMENTAL TECHNOLOGY VERIFICATION REPORT - FIELD PORTABLE X-RAY FLUORESCENCE ANALYZER - HNU SYSTEMS, SEFA-P. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-97/145 (NTIS PB2001-101679), 1998.
In April 1995, the Environmental Protection Agency (EPA) conducted a demonstration of field portable X-ray fluorescence (FPXRF) Analyzers. The primary objectives of this demonstration were (1) to determine how well FPXRF analyzers perform in comparison to a standard reference method, (2) to identify the effects of sample matrix variations on the performance of FPXRF, (3) To determine the logistical and economic resources needed to operate these analyzers, and (4) to test and validate and SW-846 draft method for FPXRF analysis. The Demonstration design was subjected to extensive review and comment by the EPA's National Exposure Research Laboratory, EPA Regional and Headquarters Superfund technical staff, the EPA's Office of Solid Waste-Methods Section, and the technology developers.
This demonstration found that the analyzer was generally simple to operate. It was designed to operate in the intrusive mode only. The SEFA-P Analyzer is an effective tool for field-based analysis of metals contamination in soil. This Analyzer can be expected to identify contaminated areas allowing investigation and remediation decisions to be made more efficiently on-site which may reduce the number of samples that need to be submitted for confirmatory analysis. Ownership and operation of this analyzer may require specific licensing by state nuclear regulatory agencies. There are special radiation safety training requirements and costs associated with this type of license.
