CLPPB undertook an evaluation to focus on a handheld XRF that could easily be brought into homes and used both for testing lead-based paint and other environmental hazards and for screening lead in food and medicinal items.
Fifty-eight test samples were acquired from seven local California childhood lead programs and through childhood lead poisoning investigations by CLPPB staff over a 10-month period (June 2009 through March 2010).
This cut-point was thought to represent the lowest lead level for which results could reliably be obtained for the CLPPB model of XRF, based on prior FDA work and initial pilot testing by CLPPB.
