| 摘 要： | 利用天然铀粉末和铀镭平衡粉末分别制作了用4种模拟土壤基质体源，并封装在4种不同几何形状的样品杯中，通过HPGeγ谱仪分析比较了63～1847keV能量范围内不同几何形状体源的效率，分析了效率差异的原因，并对在实际样品测量中选取合适样品杯提出了建议。

| Abstract: | The four separately produced simulated soil volume sources packaged in four different geometrical cups by using natural Uranium powder and Uranium-Radium equilibrium powder.These samples measured by HPGe spectrometer,efficience of differnt geometry volume sources in the range of 63-1 847 keV was compared the reasons of the differences in efficiency were analyzed,and suggestion for selecting the samples in the practical sample measurement were put for ward. |
