摘　　要：文章介绍用同轴高纯锗探测器通过测量近铀子体ＵＸ＿２的γ射线（１００１ｋｅＶ）分析铀矿石中高含量Ｕ的方法。研究了谱数据平滑处理问题，讨论了方法的特点。经标样及实际样品分析考察，方法的准确度、精密度均符合规范要求。he determination of high content uranium is effected by measurement of the weak 1 00 1keV gammaray of the near uranium daughter UX_2 using a coaxial high purity Ge detector. Thesmoothing of spectral data improves the stability. Repeated measurements of reference and realsamples showed that the method gives results with reasonable precision and accuracy.
