摘　　要：根据全面禁止核试验条约组织临时技术秘书处(PTS)对放射性核素Xe的现场视察技术要求,开展了现场视察Xe的取样分离测量技术研究,建立了Xe的分离纯化流程。流程的采样量为10m3,Xe的提取产额大于90%。采用高纯锗γ谱仪,测量24h,133Xe的最小探测浓度为0·053Bq/m3。According to the PTS technical requirement of on-site inspection radionuclide xenon, the research is developed for on-site inspection xenon sampling separation measurement. The flow of xenon separation and purification is established. As a result, the yield of Xe exceeds ninety percent when the total volume of sample is 10 m~ 3 , the minimum detectable concentration of ~ 133 Xe is 0.053 Bq/m~ 3 in twenty-four hours with the high-purity germanium γ detector.
