Grazing incidence X-ray fluorescence study of the surface leaching behaviour of synroc

A pilot study has been performed into the suitability of grazing incidence X-ray fluorescence analysis for determining leaching profiles in synroc. It is shown that dilute components can be easily measured on a bending magnet beamline, and concentration depth profiles resulting from leaching can be detected. In combination with simplified model leaching profiles, some quantitative information on leach depth can be obtained.
