本文介绍了用α计数测量U/Th含量的原理和方法
研制了一种具有时间符合功能的α计数器。对一些地质样品进行测试
通过α总计数率和符合对计数率计算出U/Th含量
并将其结果和NaIγ能谱仪的分析结果进行对比
两种方法测量结果大致相近。结果表明:α计数器可用于地质样品中钍和铀含量的分析
进而进行年剂量率的估算。
An α-counter with time coincidence function was developed to measure U and Th contents in geological samples for TL(thermoluminescence) and OSL(optically stimulated luminescence) dating.The U and Th contents in geological samples are calculated by α total counting rate and pair coincidence counting rate
and the annual dose rate can be estimated.Tests of the α-counter showed that the measurement results were comparable with that of a NaI γ spectrometer.
