Analysis of 232Th, 230Th , and 228Th in sediments showed that there was an excess of 228Th over that supported by the parents 232Th or 228 Ra in sediments in many regions. This excess 228Th with a half-life of 1.91 years can be used for dating purpose over a time period of the order of a decade, so average sedimentary rates in the Yalujiang River Estuary, and in the Huanghe River Estuary and its adjacent Laizhou Bay can be obtained from decreases in the excess 228Th activity as a function of depth in sediment.
