An enhanced sensitivity K-shell X-ray fluorescence technique for tibial lead determination
Abstract
A novel irradiation-detection geometry capable of enhancing sensitivity for the measurement of tibial lead content by K-shell x-ray fluorescence (XRF) is described. The high-count-rate system comprised a small-area high-specific-activity (0.147 GBq mm-2) 109Cd source and a large-area (nominally 20 cm2) uncollimated detector, forming an axially symmetric back-scattering arrangement. Precisions in the range +/- 4.9 to +/- 14.2 micrograms Pb (g …
