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

可靠的TL（热发光）和OSL（光学刺激的发光）使用单个等分试样的再生剂量（SAR）方法来实现，该方法优于多个等分试样添加剂剂量（MAAD）方法，从一些样品等分试样的需求的方面。在SAR测量中，通过人工辐射源在固定的几何条件下进行发光测量和人工剂量的几种重复。通过在我们的实验室中配备了小型或迷你X射线发生器的自动发光测量设备建立了实验条件，因为日本存在严重的放射性同位素（RI）源（总计40-50 MCI）。新的自动发光测量系统不仅适用于BTL和OSL，还适用于使用SAR方法的RTL。该系统的特征包含一组陶瓷加热器和玻璃核杆作为有效发光检测。实践…从九个乔蒙陶器中提取的更高，石英和费尔德斯帕提取物，假定使用了3500-6,000年前使用的，使用了四种发光测量，涉及RTL，BTL，OSL和IRSL（使用自动化的启发性亮度测量系统）。在这些结果上，将使用累积剂量和年剂量计算的RTL-AGS与其他OSL和IRSL-AGE进行了比较。结论性地，当有燃烧的考古材料中的石英提取物可用时，RTL日期被证实是最可靠的日期方法。最近，类似的RTL约会被令人满意地用于年轻的烧毁考古材料，例如屋顶瓷砖（Sairyuuji寺）和古代窑（Saitama and Hokkaido）的石头。从较低温度区域的TL-Glowcurve的基本特性搜索从液体氮温度到0℃的基本特性搜索，并结合了电子自旋共振（ESR）光谱法。结果，发现石英规范中的Al和OH杂质会与热退火温度和冷却速率一起影响TL-原位。较少的
