某公司辐射工作场所退役辐射影响分析

Analysis of Radiation Effect of Decommissioned Workplace in a Company

某公司下属的放射免疫实验室使用碘-125试剂进行放射免疫检验工作,现由于业务调整,拟对该公司辐射工作场所进行退役。在对辐射工作场所及周边环境贯穿辐射剂量率和表面污染水平监测的基础上,分析了辐射工作场所退役对公众和环境的辐射影响,表明辐射工作场所不需要进行退役治理即可达到无限制开放使用,满足辐射防护要求。

I-125 was utilized for radio-immunity laboratory in radiation workplace of a company.Because of business field change in the company,therefore,the radio-immunity laboratory is subjected to decommission.On the basis of monitoring on penetrating radiation dose rate and surface contamination of surrounding environment,the impacts of decommissioned workplace on environment and the public are analyzed.The study shows that this decommissioned workplace meets the requirement of radiation protection,and there is no need to carry out decommissioning measures on it.
