Sensitive gas‐filled proportional counters are ideal for the rapid elemental analysis of geological materials by isotope‐source XRF. They have, however, hardly been used for this purpose because of their relatively poor energy resolution and consequent difficulties associated with overlap corrections. In this paper, a new method for handling signal deconvolution is described, which greatly improves the practical application of the technique to multi‐element geological and environmental materials.
