摘　　要：FCo70-YQ型放射源运输容器是设计用于运输60Co和137Cs的医用放射源运输容器,设计容器最高装源活度60Co不超过12000C(i444TBq),137Cs不超过8000C(i296TBq)。根据国家标准《放射性物质安全运输规程》(GB 11806ˉ2004)的要求,对FCo70ˉYQ型容器进行了耐热试验。试验中测量到容器本体的最高温度为193.9℃,小于容器屏蔽材料铅的熔点温度327.3℃。试验结果证明了FCo70-YQ型容器热工设计满足国家标准《放射性物质安全运输规程》(GB 11806-2004)的要求。The FCo70-YQ-Type container is intended for transport of medical ^60Co and 137Cs sealed sources. The activity of ^60Co is less than 12 000 Ci （444 TBq）, and the activity of ^137Cs is less than 8 000 Ci （296 TBq）. FCo70-YQ Type container experienced thermal test in accordance with safety requirements of Regulations for the Safe Transpor t of Radioactive Mater ial （GB 11806-2004）. The measured maximum temperature on main body of container is 193.9℃ during testing period, which is less than the melting point of lead （327.3℃）. The results obtained proven that thermal design of FCo70-YQ container meets the requirements of Regulations for the Safe Transport of Radioactive M aterial（GB 11806-2004）.
