Abstract
In order to reduce the uncertainty of coincidence measurement, a β-γ coincidence measurement system based on digital technology is designed. The system consists of data acquisition hardware and data analysis software. It uses the data acquisition card to collect data from the detector, and then finish the dead time correction, coincidence resolving time correction and efficiency extrapolation necessary for coincidence measurement on the computer. The designed coincidence measurement system is used to measure 60Co standard source in the laboratory, and adopt two efficiency extrapolation methods to process the measurement results. The results show that the deviation of the activity of 60Co standard source measured using the designed coincidence system from the value measured using a standard device is less than 0.5%.
