项目摘要

The reliable TL (thermoluminescence) and OSL (optically stimulated luminescence)-dating methods are realized using a single aliquot regenerative dose (SAR) method which is superior to a multiple aliquots additive dose (MAAD) method from aspect of requirement of a few of sample aliquots. In the SAR measurement, several repetitions of the luminescence measurements and artificial dosing under a fixed geometrical condition by an artificial radiation source. Such experimental conditions have been established by an automated luminescence measuring apparatus equipped with a small or a mini X-ray generator in our laboratory, because a serious limitation exists in Japan for a radioactive isotope (RI) source (amounting to 40〜50 mCi). The new automated luminescence measuring system which is applicable not only to BTL and OSL but also to RTL using the SAR method. The features of this system contain a cluster of ceramics heaters, and a glass core-rod as an effective luminescence detection. Practica … More lly, quartz and feldspar extracts, from nine Jomon pottery pieces, which were assumed to be used 3,500-6,000 years ago, were followed to four kinds of luminescence measurements, involving RTL, BTL, OSL, and IRSL (infrared stimulated luminescence), using the automated luminescence measuring system. On these results, the RTL-ages, calculated using the accumulated doses and annual doses were compared with other OSL-and IRSL-ages. Conclusively, the RTL-dating was confirmed to be most reliable dating-method when quartz extracts from burnt archaeological materials are available. Recently, the similar RTL dating was satisfactorily applied for younger burnt archaeological materials such as the roof tile pieces (Sairyuuji temple) and stones of ancient kiln (Saitama and Hokkaido). An advanced luminescence dating was approached from basic property search of TL-glowcurve in lower temperature region from liquid nitrogen temperature up to 0 ℃, combined with electron spin resonance (ESR) spectrometry. As a result, Al and OH impurities in quartz specimens were found to affect remarkably the TL-properties together with thermal annealing temperature and cooling rate. Less

采用单份再生剂量法（SAR）实现了可靠的热释光（TL）和光释光（OSL）定年方法，从所需样品量少的角度考虑，SAR法优于MAAD法（上级）。在SAR测量中，在固定的几何条件下，由人工辐射源进行多次重复的发光测量和人工剂量测量。由于日本对放射性同位素（RI）源（总量为40 ~ 50 mCi）存在严重的限制，因此我们实验室已通过配备有小型或微型X射线发生器的自动发光测量装置建立了这样的实验条件。该系统不仅适用于BTL和OSL，而且适用于采用SAR方法的RTL。该系统的特点包括陶瓷加热器的集群，和一个玻璃芯棒作为一个有效的发光检测。Practica ...更多信息利用自动发光测量系统，对9个绳纹陶器样品的石英和长石提取物进行了RTL、BTL、OSL和IRSL（红外激发发光）4种发光测量。根据这些结果，将使用累积剂量和年剂量计算的RTL年龄与其他OSL和IRSL年龄进行了比较。总之，RTL测年被证实是最可靠的测年方法时，石英提取物燃烧考古材料。最近，类似的RTL测年令人满意地应用于较年轻的燃烧考古材料，如屋顶瓦片（Sairyuuji寺）和古窑（琦玉和北海道）的石头。从液氮温度至0 ℃低温区TL-发光曲线的基本性质研究出发，结合电子自旋共振（ESR）技术，探讨了一种先进的发光测年方法。结果表明，石英样品中的Al和OH杂质与热退火温度和冷却速率一起显著影响TL性能。少
