玻璃作为双参数剂量探测器的TL性能研究

DOUBLE DOSIMETRY PARAMETERS GLASS DETECTOR

玻璃受γ射线辐照后不仅光密度发生了变化，热释光的发光量也发生了变化，从而使我们有可能研制一种具有双重剂量学参数的玻璃剂量探测器，其量程约为１０２～５×１０４Ｇｙ。此项研究也有助于探讨至今尚无“定论”

This paper reports a research on using glass as material to develop a double dosimetry parameters detector. It is found that after the sample been irradiated man can not only know dose according to △A (absorbance) but also get dose by interpreting from △TL (thermoluminescent intensity). That is to say man can obtain more information from this kind of detector than ordinary one. Furthermore these two series data are independent, in the meanwhile they can be used to calibrate each other. Dose range is about 10 2Gy 5×10 4Gy. This research is useful for investigating the principles of TLD and the forming of color centers in glass.
