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。
Introduced the 2015 annual laboratory organized by the laboratory on soil and water radionuclide laboratory comparison between the relative situation. Soil is divided into spiked soil and actual soil two types of water spiked samples. Comparisons of spiked samples include 3H (unanalyzed), ~ (90) Sr, ~ (60) Co, ~ (134) Cs and ~ ) U, ~ (232) Th, ~ (226) Ra, ~ (40) K, ~ (90) Sr and ~ (137) Cs. Eight units (11 laboratories) participated in this comparison and the results were generally good. The problems found in the comparison activities were analyzed and suggestions for future comparison activities were put forward.
