This article, published in *Ancient TL* in 2011, updates dose-rate conversion factors used in luminescence and electron spin resonance (ESR) dating. The factors are derived from data provided by the National Nuclear Data Center of Brookhaven National Laboratory, specifically from Evaluated Nuclear Structure Data Files (ENSDF) and Nuclear Wallet Cards. The recalculated factors are slightly higher than previously published, except for beta and gamma emissions of U-series isotopes. The data used for the update were downloaded from the Chart of Nuclides on November 5, 2009. The article presents updated conversion factors for the 232Th, 238U, and 235U decay series, as well as for potassium and rubidium. The authors emphasize the importance of using the latest conversion factors to minimize systematic errors in age calculations. They recommend that these updated factors be used for future luminescence and ESR age determinations.This article, published in *Ancient TL* in 2011, updates dose-rate conversion factors used in luminescence and electron spin resonance (ESR) dating.
