title: Calculating the uncertainty in lead concentration for in vivo bone lead x-ray fluorescence.
abstract: A revised mathematical treatment of the calibration line intercept has been published for in vivo bone lead measurements using 109Cd-based K-shell x-ray fluorescence. The revised calibration line treatment prompts changes, presented herein, to the method for calculating the measurement uncertainty.
