Abstract: We attempt to use the Pixie-Net digitizer for the β-γ coincidence experiment in order to replaces complex traditional electronics and then to simplify experimental equipment. The measurement results show that the relative error between the measured activitivity using the Pixie-Net digitizer and the theoretical value is less than 5%, which is much better than the results with traditional electronics. It is feasible to replace traditional electronic instrument devices by the Pixie-Net digitizer. 

Key words: Pixie-Net digitizer, β-γ coincidence measurement, activity of radioactive sources
