Abstract
The analysis of lead concentration in bone utilizing LXRF can be adversely effected by overlymg tissue. A quantitative measure of the attenuation of the 10.5 keV Pb L a x-ray signal by skin and skin equivalent plastic has been conducted. Concentration ranges in plaster of Paris and doped goat bone from 7 to 90 ppm with attenuators of Lucite® and pig skin were examined. It is concluded that no quantitative or semi quantitative analysis can be achieved if overlying tissue thickness exceeds 3 mm for Pb concentrations of less than 30 ppm Pb in bone.
