Abstract
Annular XRF systems, using backscattering geometry, have advantages of convenience of use, but it is difficult to predict their sensitivity to concentrations of heavy metals at different depths, or the contribu tion of scattered radiation to the background. A Monte Carlo program h as therefore been developed to carry out calculations of this type. Se veral variance-reduction techniques are included. Preliminary results for the detection of platinum are given. (C) 1998 Elsevier Science Ltd . All rights reserved.
