Abstract

In non-destructive x-ray fluorescence analysis of ancient ceramics with varied surface shapes, a correction of the measured x-ray fluorescence intensity is required. Owing to the variations in geometry, the x-ray pathlengths will differ from those obtained for the calibration of a standard sample. A method is proposed using yttrium-39 as an outer mark element on a membrane. A comparison of characteristic peak counts before and after correction is reported for pottery pieces with different shapes. The analytical error involved in this method is discussed.
