内容記述 | Fine (1 ? 8μm) or coarse (~100μm or >50μm) mineral has been used in luminescence datings. Minerals of semi-fine sizes (8 - 50μm), however, have not been used for luminescence dating samples because of the difficulty in assessing the effective α dose rate. In this article, we propose a simple formula which gives a correction factor for α dose rate in luminescence dating with semi-fine grains The formula is based on an effective range of α particles which is incident to spherical mineral grains, α dose-rate correction factors are calculated for quartz with a diameter of 0 - 50μm assuming the effective α-particle range of 7.5, 10, 15 and 20μm. The results were applied to IRSL datings of tephra and sediments from archaeological sites, and reasonably accurate ages were abtained. | |||||
