In this study, we develop a new radioxenon detection system based on beta-gamma coincidence to improve the sensitivity of detection in laboratory analysis. The designed system is a new prototype that is tested by injecting the 222Rn and its daughters (214Pb and 214Bi) as a beta–gamma emitter and also Xe-131m gaseous sources, which are in the interest of CTBTO. Further, the system is calibrated and checked using a Ho-166m source. This system consists of a NaI (Tl) as a gamma, X ray radiation detector, and a Silicon detector for the beta or the conversion electron detection. Silicon is used for improving energy resolution and minimizing the potential for memory effect compared to the scintillator detector. The list-mode multi-parameter data acquisition system is used to set up coincidence parameters. The efficiency of two detectors and MDA are obtained.
