近铀子体高能γ能谱法分析铀矿石中高含量铀

Determination of High Content Uranium in Uranium Ores by Use of High Energy Gamma-Ray Spectrum of the Near-Uranium Daughter

摘要: 文章介绍了用同轴高纯锗探测器通过测量近铀子体ＵＸ２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。

Abstract: 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 re
