【Abstract】 In order to meet the requirement of 99Mo-99mTc generator batch production, the measurement system of 99Mo-99mTc generator equilibrium activities has been developed, which could be measured on line at real-time. Functions and performance of the measurement system are introduced in the paper. Experiments results proved that the system simple operation, fast and accurate measurement. Both the repeatability and stability are less than 0.5%, and expanded uncertainty is less than 5%.更多还原
