Fault Tree Analysis on Radiation Hazards in Underground Uranium Mines and Prevention Countermeasures

Abstract:

Workers in underground uranium mines work chronically in the opening radiation environment, the radiation hazards they suffered has attracted public’s attention. So some effective measures must be carried out to control worker’s received radiation dose. Fault tree analysis is a deductive system safety analysis method, which can offer decision basis for accident prevention and safety management. Based on the above two advantages, firstly, the paper analyzes the radiation hazards in underground uranium mines and their influencing factors. Then, the fault tree of radiation hazards is established in underground uranium mines, five groups of minimal path sets and the structure importance degree of each basic event are obtained. Finally, according to the results of fault tree analysis, some prevention countermeasures are putted forward to prevent radiation hazards.
