Radioxenon detection systems are valuable tools used by the Comprehensive Nuclear-Test-Ban treaty Organization (CTBTO) to verify whether an event is nuclear in nature. These systems monitor four xenon isotopes of interest in the atmosphere: 131mXe, 133mXe, 133Xe, and 135Xe. The elevated concentration of these isotopes in specific ratios is indicative of a nuclear weapon detonation. These isotopes have long half-lives and emit coincidence beta and gamma radiation. These characteristics make them the best candidates for this purpose. This work reviews the recent development of radioxenon detection systems focusing on the detection systems developed by the Radiation Detection Group at Oregon State University. Important results from these systems, Minimum Detectable Concentration (MDC) and energy resolution are included in this study. These systems are compared in terms of the memory effect, electron backscatter, and complexity. The advantages and disadvantages of each system are discussed and suggestions to mitigate the problems and improve their performances are provided. |
