目的对苏南某60Coγ辐照装置进行环境辐射水平监测。方法使用便携式X、γ剂量率仪,采用搜索检测与辐射状布点测量相结合的方法进行每月一次,为期一年的辐射监测,测量工作场所和装置周围环境的辐射吸收剂量率。结果监测值均在国家标准(屏蔽设计监督区剂量率为2.5μGy/h)范围之内。结论苏南某辐照中心辐照装置安全性良好,没有对周围环境产生放射性危害。
Objective To monitor the environmental radiation level of a 60Coγ irradiation device in southern Jiangsu Province. Methods A portable X and γ dose rate meter was used to conduct monthly and one-year radiation monitoring using a combination of search and radiometric measurements to measure the radiation dose rates in the workplace and in the environment surrounding the device. The results of the monitoring values are in the national standard (shield design supervision area dose rate of 2.5μGy / h) within the range. Conclusion The radiation equipment of a radiation center in southern Jiangsu is safe and has no radioactive hazard to the surrounding environment.
