The U.S. Environmental Protection Agency sponsored a 1 1/2 day workshop to review the current status of portable x ray fluorescence (XRF) technology. The goal of the workshop was to identify problems and limitations that could result in portable XRF measurement error and to develop a set of performance parameters to generate or verify figures of merit that are comparable across the technology. The report synopsizes the remarks of nine of the thirty-two attendees who addressed topics ranging from HUD's needs and lead policy issues to XRF instrument design, operation and applications. Group consensus definitions and implementation techniques were developed for such performance parameters as precision, bias, detection limits, interpretation of substrate effects and the evaluation of instrument physical characteristics.
