False alarm rate of artificial radioactive aerosol continuous monitor is inevitable. When the standard deviation of artificial radioactive aerosol concentration is determined, the minimum detection limit and false alarm rate are a pair of contradictory relations. This paper proposes the concept of alarm measure, transforms the results obtained by several deduction algorithms into alarm measure, and then uses DS evidence theory to fuse several alarm measures. The fused results are used as the basis for whether to alarm. This method can greatly reduce the false alarm rate while keeping the minimum detection limit unchanged. The experiment proves the effectiveness of this method.
