含^(60)Co极低放土壤废物的填埋处置

Landfill disposal of very low level soil waste containing ^(60)Co

在对四川省城市放射性废物库暂存的含^(60)Co极低放土壤废物进行源项分析的基础上确定了填埋处置方案。根据填埋处置方案对该批含^(60)Co极低放土壤废物进行了填埋,对填埋过程中工作人员受照剂量进行了估算。经计算,此次填埋操作过程中工作人员最大个人剂量为103.07μSv,满足相关剂量控制要求。

Based on the source term analysis of ^(60)Co containing very low level radioactive soil waste which was temporarily stored in urban radioactive waste repositories in Sichuan Province,a landfill disposal plan was determined through research on radioactive waste disposal sites in Sichuan Province and a design of landfill units was put forward.According to the landfill disposal plan,this batch of very low level soil waste containing ^(60)Co was landfilled,and the radiation dose to the workers during the landfill process was estimated.After calculation,the total personal dose to the workers during this landfill operation is 103.07μSv,that meets relevant dose control requirements.
