摘要：

The accuracy of the ESR ages of fossil shells from the Boso Peninsula, Ooiso Hills and the Miyazaki Plain in Japan in the Middle to Upper Pleistocene were examined. The measurement test with a thermoluminescent dosimeter at the sampling point suggests that the dose rate of cosmic rays must be added to the calculated dose rate from chemical analysis. The results show that the ESR ages are in good agreement with the stratigraphically estimated ages. However, according to the chemical analysis of the mollusc shell itself, several shells give an abnormally high concentration of uranium. This may indicate that the shell has absorbed uranium from outside especially in sandy sediments.
