37家医疗机构核医学放射性废物处置现状分析

Analysis of the nuclear medicine radioactive waste management status in 37 medical institutions

目的掌握河北省医疗机构核医学科放射性废物管理现状,以期为提升监管效能提供有效数据和理论基础。方法设计核医学放射性废物处置调查表,采取医疗机构自查、卫生监督机构对辖区内的医疗机构进行现场调查相结合的方法对核医学科放射性废物处理情况等进行了相关调查。结果截止到2018年底,河北省开展核医学的医疗机构有37家,其中设有放射性废物储存室的37家、面积329 m2;设有放射性废液衰变池35家,体积2449 m3,以三级衰变为主,控制方式主要为自溢。结论河北省医疗机构核医学放射性废物管理模式有待完善,今后应提高对放射性废物管理的重视程度,有效确保放射性废物的处理质量。

Objective To study the basic situation of radioactive waste management in clinical nuclear medicine departments of medical institutions in Hebei province, so as to provide the effective data and theoretical basis for the improving regulatory effectiveness. Methods The questionnaire for radioactivity waste disposal in nuclear medicine was designed,and then and relevant investigations were conducted on radioactive waste disposal in nuclear medicine by combining self-examination of medical institutions and on-site investigation of medical institutions within the jurisdiction by health supervision institutions. Results By the end of 2018,there were 37 medical institutions established clinical nuclear medicine departments carrying out nuclear medicine in Hebei province, among which 37 had radioactive waste storage rooms with a total area of 329 m^2, 35 had radioactive waste water decay pools with a total volume of 2 449 m^2, which were dominated by mainly three-stage decay and controlled by self-overflow. Conclusion It is necessary to improve and pay more attention to the radioactive waste management model of medical institutions in Hebei province, to effectively ensure the quality of radioactive waste treatment.
