Th 230 decay
WebThe 230 Th/U dating method is based on measuring the degree of secular equilibrium between 238 U and its daughters, 234 U and 230 Th. As the abundances of 234 U and 230 Th are low, the precision of 230 Th/U dating is limited by counting statistics. Therefore, before analysis, it is necessary to enrich and purify the U and Th in the samples.
