抄録
Electron spin resonance (ESR) dating is based on the measurement of microwave absorption by trapped electrons or holes, which increases over time in solids. The method is applicable to a wide range of materials and has great potential for Quaternary dating; however, there are still problems in evaluating past radiation dose (DE) and external dose rate (Dex) and in the normalization of the procedures. In the last few years, efforts of solving these problems have been made; appropriate techniques for estimating DE and Dex were proposed, minimum requirements for publishing ESR ages were suggested, and the second interlaboratory comparison project was carried out. It is hoped that the proposed techniques and requirements will be widely used and that ESR dating will contribute to Quaternary geochronology.
