石英的粒度对其前剂量热释光效应的影响

Influences of the Different Sizes of Fine-Grain Quartz on the Thermoluminescence Dating of Quartz Pre-Dose Technique

本文介绍了用石英粉末进行前剂量热释光效应的测量方法，并就不同粒度的石英样品对其110℃峰的TL响应的影响进行了专门研究．结果表明石英前剂量样品的TL值随石英粒度的变化而变化，且粒度悬殊越大则TL值的相对偏差也愈大．

In this paper, the method of measuring TL dating for fine-grain quartz pre-dose technique is introduced and the influences of different sizes of fine-grain guartz on the thermoluminescence dating of guartz pre- dose technique is researched. The results show that the TLD of quartz on 110℃ changes with different sizes of its fine-grain and the more different the sizes of guartz, the bigger the relative error of TLD.
