极低放固体废物填埋作业人员个人剂量估算

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 mSv。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。

Dose Estimation to Landfill Disposal Worker for Very Low Level Radioactive Waste

Objective To estimate the personal dose of the worker who are engaged in treating the very low level radioactive solid waste landfill and test dose whether or not their annual effective can meet the requirements of enterprisemanagement target value.Methods According to the estimation model from "Landfill disposal for very low level radioactive waste"(GB/T 28178-2011), the external irradiation and Inhalation exposure dose were estimated.Results The conservative estimation of the landfill plant workers'annual effective dose is 0.86mSv.Conclusion During the the very low level radioactivesolid wastereceived,the key-workers have no radiation hazard.
