Short summary

We evaluate different methods for the potassium (K) concentration determination in feldspars and the impact of the K concentrations on dose rate calculations for feldspar luminescence dating. Our results show discrepancies between published K concentrations and our measured K concentrations. Therefore, we emphasize measuring K concentrations via bulk measurements and single-grain techniques to obtain more accurate results.
