摘要

在细粒热释光测定年代中，真实的α剂量必须被转换成与β等效的内照射剂量，这个转换由α内照射效率Ｋ值完成。但对每个样品来说，这个Ｋ值是无法测定的，能测到的只是每个样品的α外照射效率Ｋ３．７。为此，研究了α内、外照射效率的转换系数以及测定的方法。结果表明，与石英近似的ＣａＳＯ４的α内外照射效率的转换系数在考古样品中为０．８４７，与理论计算值０．８５很一致。

Abstract

It is important in fine-grain TL dating that the full α dose must be converted into the equivalent β dose. Although the conversion coefficient K for internal radiation efficiency can not be measured directly for each sample

it is possible to measure the external radiation efficiency K 3.7 . For this purpose a special study for the conversion factor of K to K 3.7 has been made using ultrathin TLD. The results show that the conversion factor of the TLD for archaeological samples is 0.847

which is in agreement with the calculated value 0.85.
