三种铝样品中^(232)Th和^(238)U的含量

^(232)Th AND ^(238)U CONTANTS IN THREE Al SAMPLE

本文介绍了用HPGe反康普顿γ谱仪分析三种铝样品(L4R,Lr11CR,Cz)中天然放射性核素^(232)Th和^(233)U含量的结果,其中^(233)U的含量为0.8—0.52Bq/kg,^(232)Th的含量为2.3—6.8Bq/kg。

This paper presents the investigation with HPGe anti-com-pton γ spectrometer of naturally-occurring radionuclides ^(232)Th and ^(238)Uin Al samples of three different kinds (L4R, LrllCR and Cz).The resultsindicate that the ^(232)Th contant ranges from 2 .3 to 6 .8 Bq/kg,and ^(233)Ufrom 0.38 to 0.52 Bq/kg.
