Abstract
SummaryThis paper outlines the physical measurements that determine the potassium–argon decay constants; compares the constants currently in use with those derived from the best physical measurements; and shows the magnitude of error in the time-scale due to different estimates of the constants and to a 5 per cent error in each of the constants. Tables are given which can be used by the non-specialist to relate K–Ar ages directly to the experimentally determined argon/potassium ratios using ‘standard’ constants.
