Ⅰ类放射源运输的辐射环境影响分析——以某辐照中心某次放射源钴-60运输为例

The Radiation Environment Impact Analysis for Transportation of Ⅰ Type Radioactive Source——A Case Study of the Cobalt-60 Transport in a Certain Radiation Center

以某辐照中心Ⅰ类放射源运输过程为例,通过介绍了放射源运输环境影响的剂量估算模式,并采用该模式实例计算,结果表明,正常工况和事故工况对工作人员及公众所致的辐射水平符合GB11806-2004规定;还简要对Ⅰ类放射源在运输中涉及装载容器、装运工具、事故分析等方面的辐射环境影响分析。

Taking the transport process of I radiation source in a certain radiation center as the example, this study introduced the dose of Environmental Impact Estimation Model in radioactive source transportation and adopted the practical calculation of this model. The results showed that radiation levels in normal and accident conditions conformed to the regulations of GB11806 - 2004 to staff and the public; this study also briefly analyzed the radiation environment impact in the field of transportation, such as containers, loading tools, accident analysis and so on.
