2010年度CTBT放射性核素实验室滤材样品国际比对

2010 CTBT Intercomparison of Atmospheric Particle Filter Samples

摘要: 北京放射性核素实验室参加了全面禁止核试验条约（CTBT）筹委会临时技术秘书处（PTS）组织的2010年度放射性核素实验室气溶胶滤材样品国际比对，从参考样品中分析出20种相关放射性核素，计算得到了这些核素的活度及活度浓度，并推算了零时。PTS反馈结果表明，北京核素实验室核素识别准确，活度、活度浓度计算和零时推算与参考值一致，在此次比对中成绩优异。

Abstract: This article presents the experience that Beijing Radio-nuclide Laboratory participated in the proficiency test exercise organized by the Provision Technical Secretariat of the CTBT in 2010. Twenty radio nuclides were identified and the zero time was determinated. After evaluation the results reported by our laboratory of radio nuclide identification, activity, activity concentration and zero time were considered excellently.
