摘要

Underground caverns have important military and civilian uses, but their internal natural radiation may endanger human health, and it is necessary to implement protection. The protective measures taken for an underground cavern in Chongqing have obvious effects. The results show that cleaning the radiation source in the environment and sealing the gap of the hole can re-duce the natural radiation intensity inside the cavern to a certain extent, reducing the ambient temperature can significantly reduce the natural radiation intensity inside the cavern, the use of press-in ventilation can greatly reduce the natural radiation intensity inside the cavern, the cumulative drop can reach 25.63%, and the protective effect is obvious. These protective measures can be used in underground caverns to improve the safety of military and civilian activities.
