摘　　要：某密封源生产设施由于原设计考虑不周、配套设施建设水平不高、设施维修维护不足等原因存在安全隐患。从工艺布局、辐射防护和监测、废液收集和公用工程等方面进行了研究分析,提出加强热室屏蔽性能、辐射监测功能、废液分类收集管理的方案,并对通风、建筑装修、自控和消防等进行完善。结果表明,改善后的密封源消除了安全隐患,降低了人员受照风险,满足法律法规的要求和后续生产需求,保护了公众和环境。Some potential hazards occur in a sealed radioactive source workshop,because of the inadequate consideration in the original design,the improper construction of supporting facilities and insufficient maintenance.The design principles and key factors are studied from the factors such as process layout,radiation protection and monitoring,radioactive liquid collection and utility systems,and a suitable solution is put forward,including optimizing personnel traffic routes and radioactive material transport routes,enhancing the shielding and monitoring of hot cells,and reinforcing the classification and collection of radioactive liquid waste.In addition,the ventilation, decoration,automatic control and fire protection systems are improved.With these measures above, the potential safety hazards are removed,exposure risks are reduced,applicable statutory and regulatory requirements and follow-up production demands are satisfied,to protect the public and the environment properly.
