目的对极低放固体废物处理人员个人剂量进行估算,检验其年有效剂量能否满足企业管理目标值要求。方法根据《极低水平放射性废物的填埋处置》(GB/T 28178-2011)提供的外照射剂量估算模式及吸入内照射剂量估算模式,对填埋场作业人员个人剂量进行估算。结果填埋厂作业人员年有效剂量保守估计为0.86 m Sv。结论极低放固体废物填埋场在废物接收过程中,不会对关键作业人员产生辐射危害。
Objective To estimate the personal dose of very low level solid waste disposal personnel and test whether the annual effective dose can meet the requirements of enterprise management objectives. Methods Based on the estimation model of external radiation dose and the estimated internal dose of radiation dose provided by Landfill disposal of very low level radioactive waste (GB / T 28178-2011), the individual dose of landfill operator was estimated. Results The annual effective dose of landfill operators was conservatively estimated to be 0.86 m Sv. Conclusions Very low level solid waste landfill will not cause radiation hazard to key operators during the waste receiving process.
