Abstract
The present application relates to a method and system for measuring radioactive waste barrels outside a nuclear power plant, the method comprising: obtaining measurement parameters of a waste barrel to be measured; determining the detection efficiency of equivalent nuclides and calculation data according to the measurement parameters; calculating the activity concentration of all easy-to-measure gamma nuclides and all difficult-to-measure gamma nuclides according to the detection efficiency of equivalent nuclides and the calculation data; and evaluating whether the waste barrel to be measured meets the clean control requirements according to the activity concentration of all easy-to-measure gamma nuclides and all difficult-to-measure gamma nuclides. The present application can significantly improve the accuracy, reliability and automation level of barrel-out measurement, and provides a powerful technical means for the clean control of radioactive waste.
