摘要
目的对某医院核医学科PET/CT中心进行放射卫生防护现状分析,评价其是否符合放射卫生要求,对薄弱环节提出相应的对策。方法依据国家相关标准对现场进行检测和调查,将所得数据和资料与标准进行比较。结果该医院核医学科PET/CT中心核医学工作场所及周围环境辐射水平最大值为0.40μSv/h,工作场所表面污染最大值为0.20 Bq/cm2。结论该医院核医学科PET/CT中心选址适宜,布局基本合理,辐射防护检测符合国家标准要求,有完善的放射防护管理制度,正常运行条件下可以有效的预防和控制职业病危害。
Objective To analyze the radiation protection situation of nuclear medicine PET/CT workplaces in a hospital so as to evaluate whether it conforms to the criterion and provide a proposal for the weak item. Methods To detect and investigate the radiation dosage of workplaces according to the national standards, and compare the results with the national standards. Results The maximum radiation rate of workplaces and surroundings in PET/CT center was 0.40 μSv/h. The maxinmm surface contamination in the PET/CT workplaces was 0.20 Bq/cm^2. Conclusion Site selection and composition was appropriate. The radiation protection level in the PET/CT workplace in the hospital was qualified according to the national standards. The hospital has a complete radiation protection management system and under normal operation can effectively prevent and control occupational disease hazards.
