摘　　要：介绍了2015年度由本实验室组织的关于土壤和水中放射性核素实验室间测量比对的相关情况。土壤分为掺标土壤和实际土壤两类,水为掺标样品。掺标样品的比对项目包括3H(土壤中不分析)、^(90)Sr、^(60)Co、^(134)Cs和^(137)Cs,实际土壤的比对项目包括^(238)U、^(232)Th、^(226)Ra、^(40)K、^(90)Sr和^(137)Cs。8家单位(11个实验室)参加了本次比对活动,比对结果整体良好。针对比对活动中发现的问题进行了分析,并对以后的比对活动提出了建议。Inter-comparison among analytical laboratories for measurements of radionuclides in soil and water samples is described in this article. Inter-comparison media included spiked soil,real soil,and spiked water.Determination of ^90Sr,^60Co,^134Cs and ^137Cs for spiked soil,^238U,^232Th,^226Ra,^40K,^90Sr and ^137Cs for real soil,and ^3 H,^90Sr,^60Co,^134Cs and ^137Cs for spiked water were carried out. Eleven laboratories participated in this inter-comparison,and the result of inter-comparison was fine. Key problems found during the intercomparison are summarized and some suggestions are put forward for future inter-comparison activities.
