一、原理在热释光测定年代中用TLD测量标本内部的β吸收剂量已有介绍,但是用它测量标本内部的α吸收剂量尚未见成功的报道,因为这是一个很困难的工作,我们根据剂量学的空腔理论研究了用超薄型TLD测量标本内部α吸收剂量的实验。即当一种介质存在于另一 First, the principle TLD in the thermoluminescence measurement of β-ray absorptive dose within the specimen has been introduced, but the use of it to measure the specimen within the α-absorbent dose has not been successfully reported because it is a very difficult task, we based on Theories of dosimetry The cavity theory was used to study the experiment of measuring the intracellular a absorbed dose with an ultrathin TLD. That is, when one medium exists in another
