Environmental Technology Verification Report: Field Portable X-ray Fluorescence211 Analyzer. HNU Systems SEFA-P. Superfund Innovative Technology Evaluation

摘要

In April 1995, the Environmental Protection Agency (EPA) conducted a211u001edemonstration of field portable X-ray fluorescence (FPXRF) Analyzers. The primary 211u001eobjectives of this demonstration were (1) to determine how well FPXRF analyzers 211u001eperform in comparison to a standard reference method, (2) to identify the effects 211u001eof sample matrix variations on the performance of FPXRF, (3) To determine the 211u001elogistical and economic resources needed to operate these analyzer, and (4) to 211u001etest and validate and SW-846 draft method for FPXRF analysis. The Demonstration 211u001edeign was subjected to extensive review and comment by the EPA's National 211u001eExposure Research Laboratory, EPA Regional and Headquarters Superfund technical 211u001estaff, the EPA's Office of Solid Waste-Methods Section, and the technology 211u001edevelopers. This demonstration found that the analyzer was generally simple to 211u001eoperate. It was designed to operate in the intrusive mode only. The SEFA-P 211u001eAnalyzer is an effective tool for field-based analysis of metals contamination in 211u001esoil. This Analyzer can be expected to identify contaminated areas allowing 211u001einvestigation and remediation decision to be made more efficiently on-site which 211u001emay reduce the number of samples that need to be submitted for confirmatory 211u001eanalysis. Ownership and operation of the analyzer may require specific licensing 211u001eby state nuclear regulatory agencies. There are special radiation safety training 211u001erequirements and costs associated with this type of license.
