摘要

为检验核素实验室对大气颗粒物滤材样品中放射性核素的分析能力，全面禁止核试验条约筹委会临时技术秘书处从2000年开始每年组织一次能力验证活动。2012年度核素实验室能力验证活动中，参考样品中添加了24种放射性核素（其中主要核素11种，次要核素13种），北京放射性核素实验室使用相对效率为76%的HPGe ?谱仪系统完成了样品的测量分析，准确识别出了11种主要核素和12种次要核素，主要核素活度测量结果准确，由95Nb/95Zr活度比推算的零时与参考值之间相差仅0.03d。

Abstract

Background: To assess the capability of radionuclide laboratories

the proficiency test exercises (PTEs) of filter samples have been carried out by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) once a year since 2000. Purpose: This article presents the experience that Beijing radionuclide laboratory participated in PTE2012. Methods: A total of twenty four nuclides were added in the reference sample

of which eleven are considered “major” and thirteen are considered “minor”. The sample was measured by an HPGe detector with 76% relative detection efficiency. Results and Conclusion: Eleven major and twelve minor nuclides were identified in the reference sample. The measurement activities of major nuclides are accurate and the zero time that determined by the 95Nb/95Zr activity ratio is in agreement with the reference value

and the deviation is only 0.03 d. Abstract
