摘　　要：国家针对伴生放射性矿辐射监管出台一系列措施,为此,核工业地质分析测试研究中心组织了“BRIUG IC-2018伴生放射性矿中放射性核素及重金属的检测实验室间比对”活动,国家核安保技术中心实验室积极参与了238 U,232 Th,226 Ra,40 K的比对活动,采用《土壤中放射性核素的γ能谱分析方法》对测量参数,样品的装样条件等做了研究,在比对活动中取得满意结果。表明该实验室已具备较强的检测能力,为今后开展类似的核素检测工作奠定了坚实的基础,最后对今后的工作改进提出了一些建议。The state has issued a series of measures to regulate the radiation of associated radioactive ores.For this reason,the Beijing Research Institute of Uranium Geology organized the activity of“BRIUG IC-2018 Interlaboratory Comparison of Radionuclides and Heavy Metals in Associated Radioactive Mines”.Our laboratory actively participated in 238 U,232 Th,226 Ra,40 K comparing activities and studied measuring parameters,sample loading conditions and so on.Satisfactory results were obtained in the comparison activities.It shows that our laboratory has strong detection ability,which lays a solid foundation for similar radionuclide detection work in the future.Finally,some suggestions for future work improvement are put forward.
