Abstract: With many nuclear technology application units in Wuhan, the host city of the 7th CISM Military World Games, there is some risk for nuclear/radiation accidents. By identifying and evaluating the risk factors involved, 12 types of accidents that may occur were determined, along with the risk level. We then formulated targeted prevention and control measures, to move the radiation emergency management threshold forward, which's effectively guaranteed nuclear/radiation safety while ensuring the normal production activities of these units during the games.

Key words: the 7th CISM Military World Games, Nuclear/radiation risk, Rrisk assessment, Control
