摘要：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 238U, 232Th, 226Ra, 40K 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.
