某micro-PET中心的辐射监测与放射防护评价

Measurement and Evaluation of Radiation Dose in the micro- PET Center

目的了解micro-PET回旋加速器中心运行过程中的对周围环境、放射工作人员和公众的辐射影响。方法通过现场监测回旋加速器中心对周围环境产生的辐射水平。对产生的主要放射性污染源及污染途径进行分析。结果micro-PET中心运行过程中放射工作人员、公众接受的辐射剂量可达0.31 m Sv/a和0.1 m Sv/a,对周围环境造成一定辐射。结论 micro-PET项目对环境、公众、放射工作人员的影响均符合有关规定,放射性废物经有效处理达到排放要求。

Objective To evaluate the radiation effects to the surrounding environment and the radiation workers and the public in the micro PET Center. Methods By the surrounding pathway radiation level the on- sitemonitoring centers the main radioactive sources of pollution and contamination pathway were analyzed. Results In the operational process of the micro-PET center,the radiation dose to the radiation workers and the public is 0. 31 m Sv / a and 0. 1 m Sv / a,causing some radiation to the surrounding environment. Conclusion The impact of the micro- PET project on the environment、the public 、the radiation workers is in comformity with the relevant provisions. The radioactive waste by effective treatment can meet the requirements standards to discharge.
