摘要

研究了在任意Th、U含量和Th-U比覆盖整个范围（即0≤Th/U≤∝）时总α计数率对年剂量的转换因子及其误差。结果表明

当不测定Th-U比而只测量总α计数率时

最终引起的年龄误差对0≤Th/U≤∝来说为±5.1％-±8.3％

对1.1≤Th/U≤9.5来说只有±2.5％％-±4.1％。

Abstract

The annual dose conversion factors of gross a count rate and their errors for arbitrary Th and U contents and the Th/U weight ratio covering the entire range 0≤Th/U ≤∞ were calculated. The results show that the error appearing in the final TL age estimate will be±5.1% to 8.3% for 0≤Th/U≤∞ and only ±2.5% to ±4.1% for 1.1≤Th/U≤9.5 when the Th/U ratio is not determined but only the gross a count rate is measured.
