目的论证建设项目的可行性,保障放射工作人员和公众的健康与安全,同时为卫生行政部门的放射防护设施设计审查提供依据,为建设单位改进放射防护设施设计、完善放射防护措施和放射卫生管理提供指导性意见。方法通过对建设单位所提供的有关资料、现场调查资料以及与同类设备的类比分析,将分析结果与相关法律、法规的规定和标准要求相比较并对符合程度做出评估。结果在正常运行情况下对职业照射和公众照射,预期可控制在相应年剂量限值的1/4以下即5 mSv,即对职业照射为5 mSv,对公众照射为0.25 mSv,产生的辐射危害水平符合国家有关标准的要求。结论该项目为职业病危害严重的建设项目,且该项目的放射防护设施建设可行。
Objective To demonstrate the feasibility of construction projects and to ensure the health and safety of radiation workers and the general public. At the same time, it provides the basis for the design review of the radiation protection facilities of health administration departments, improves the design of radiation protection facilities for construction units, and improves the radiation protection measures and radiation health management Provide guidance. Methods Based on the relevant information provided by the construction unit, field survey data and analogy analysis with similar equipment, the results are compared with the relevant laws and regulations and the standard requirements and the degree of conformity is evaluated. Results In normal operation, occupational exposure and public exposure are expected to be controlled at less than 1/4 of the corresponding annual dose limit, ie 5 mSv, ie 5 mSv for occupational exposure and 0.25 mSv for public exposure, resulting in radiation hazard The level of compliance with the relevant national standards. Conclusion This project is a serious construction project with serious occupational diseases, and the construction of radiological protection facilities of this project is feasible.
