摘　　要：为促进辐射监测实验室间技术交流,提升国内辐射监测技术水平,生态环境部核与辐射安全中心联合苏州热工研究院有限公司组织开展了辐射监测实验室间水中总α、总β放射性测量比对工作。全国共有41家单位实验室参与,对结果采用稳健Z比分数法进行评价。共有36家报送总α放射性结果,评价结果为:30家满意;5家异常;1家离群。共有41家报送总β放射性结果,分析结果为:40家满意;1家异常。通过组织全国性辐射监测比对活动(统计结果满意率在83%~97%),基本摸清全国水中总α、总β放射性测量水平,也为今后开展各项比对工作积累了经验。In order to promote the technical exchange and improve the technical level among radiation monitoring laboratories.The Nuclear and Radiation Safety Center,together with Suzhou Nuclear Power Reserch Institute(SNPI),organized the measurement of total radioactivity in water betweenαandβ.A total of 41 unit laboratories participated in the evaluation,and the results were evaluated by the robust Z-score method.A total of 36 radioactive companies reported results ofα,of which 30 were satisfactory,5 were abnormal,and 1 was outlier.A total of 41 radioactive companies reported results ofβ,of which 40 were satisfactory and 1 was abnormal.By organizing national radiation monitoring and comparison activities,the satisfaction rate of statistical results was 83%~97%,basically mapping out the totalαandβradioactivity measurement levels in water across the country,and accumulating experience for carrying out various comparison work in the future.The annual regular comparison of radiation monitoring projects can provide an effective method for monitoring and analysis quality control,and provide support for the laboratory to continuously issue reliable data and results to the outside.
