| 摘 要： | 本文报道中国计量科学研究院最近组织的一次环境放射性样品锗γ谱测量比对。21个比对实验室用锗γ谱仅测量了两个封装在凹形杯内的河泥样品中7种放射性核素的活度。比对取得比较满意的结果。掌握正确的测量分析方法和有可靠的刻度标准源是测量取得好的结果的重要原因。对比对测量中存在的问题进行了讨论。

| Abstract: | Intercomparison of radionuclide measurement with Ge gamma-ray spectrometerfor environmental samples was organized by the National Institute of Metrology.The activi-ties of seven radionuclides of two sediment samples in Marinelli beakers are measured by 21participanting laboratories.The results of the intercomparison are satisfactory due to adopt-ing correct analysis methods and reliable reference sources.Problems uncountered in the in-tercomparison measurement are also discussed. |
