| 内容記述 | The human tooth has been used for dose estimation at Hiroshima and Nagasaki or accident dosimetry by the technique of electron spin resonance at room temperature or liquid nitrogen temperature. Thermoluminescence technique was also applied to the tooth enamels, but chemiluminescence and the stench from them at high temperature make the TL technique impracticable to use as a dosimeter. Optically stimulated luminescence (OSL), which has been developed in the last two decades, is a phenomenon at relatively low temperature. In this study, the OSL from a dentin and an enamel separated from a human tooth is observed, and its potential as a dosimeter is discussed.Infra-red stimulated luminescence (IRSL) was observed both for the dentin and enamel, but blue-light stimulated luminescence (BLSL) was observed only for the enamel. The dose dependences was observed for the IRSL and BLSL from the dentin and enamel employing the single aliquot technique. It was found that luminescence of the dentin and enamel show supralinear dose response. BLSL of the enamel caused the fading of ca. 10%, but the BLSL of the dentin shows no fading. It is suggested that BLSL of the dentin is suitable for the accident dosimetry and age determination of human fossil. | |||||||||
