A radon detector data acquisition system based on waveform resolution algorithm was designsed,by using a new liquid scintillator detector as the radon sensor,a small low-power hardware platform with excellent performance was designsed and implementsed,and waveform resolution and cascade decay recognition algorithms on the hardware platform was implementsed.~(220)Rn gas generated by~(232)Th diffusion source is used to test the data acquisition system,and the optimal parameters of waveform resolution algorithm and cascade decay extraction algorithm are determined.The test results show that the data acquisition system can effectively select radon cases.The miniaturized low-power data acquisition system designed and implemented in this paper has effectively played the advantages of the new liquid scintillator detector,and has a good application prospect in the radon detection field.
