摘要
目的探讨γ辐照装置安全退役。方法根据国家相关法律、法规与条例,部门规章、相关标准与规范,进行退役管理、环境监测。结果废旧放射源退回生产单位,工作场所γ辐射水平、β表面污染水平退役监测结果,贮源井水、土壤样品等检测分析结果,井底、井壁表面β放射性物质污染测量结果,满足清洁解控的要求,退役后能够保证公众剂量约束值小于0.1 mSv/a,可以重新开发利用。结论辐照装置退役场址可以无限制开放使用。
Objective To investigate the security management of the y irradiation facilities decommissioning.Methods Referring to the relevant national laws,regulations and rules,standards and norms.Results All the waste radioactive sources were finally returned to the original factories.By detecting and analyzing the radioactive substances in the soil near the irradiation facilities and the stored water in the well as well as those at the bottom and on wall of the well,we finally came to a monitoring result showing that the γ and β radiations in the area had reached the clearance level,which can ensure the public dose limit to stay less than 0.1mSv/a.Conclusion The decommissioning site of irradiation facilities can be used unlimitedly.
