Abstract
The objective of this investigation was to obtain an indication of the validity of the field data resulting from the use of a portable x-ray fluorescence lead detector commonly used by local lead paint detection programs. This report is intended to provide guidance in the use of portable x-ray fluorescence lead detectors by housing and/or health authorities who are responsible for the collection and interpretation of field data as part of lead paint control programs. The response characteristics of such an instrument to conditions that are related to those encountered in the field have been investigated and the results are presented in this report. The affects of calibration standards, state of charge, paint overlayers, substrate and distance on instrument response are discussed, in addition to the limit of detection and precision. The accomplishment of these tasks required the development of panel-type lead calibration standards. These standards encompass the concentration range from 0.1 mg/cm² to 9.0 mg/cm².
