摘要: 简要介绍了某137Cs源生产线操作箱室的去污工作,总结了作业实践的经验和教训。箱室去污后,热室前工作位置γ辐射剂量率从30~50 μSv/h下降到6~8 μSv/h;工作箱前工作位置从70~250 μSv/h下降到小于10 μSv/h;回收的去污废液总活度为247.9 Ci,去污效率为97.4%。

Abstract: A decontamination action of operatingchambers in a 137Cs source production line, aimed at maintenance and modification, is briefly introduced. As a result, radiation levels at working positions in front of hot cells decreased from 30-50 μSv/h to 6-8 μSv/h, whilethose for work chambers decreased from 70-250 μSv/h to less than 10 μSv/h. The gross decontamination efficiency is estimated to be up to 97.4%.

Key words: 137Cs source production line, Decontamination, Operating chambers
