Abstract
The monitoring of four radioxenon isotopes stands out as a key technology employed in detecting underground nuclear tests. In support of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), we develop and calibrate a novel radioxenon detection system based on beta-gamma coincidence, utilizing NaI(Tl) and silicon detectors for gamma and beta radiation detection. To assess its performance, the prototype detection system undergoes rigorous testing with 222Rn and 131mXe sources. A 166mHo source is employed for energy calibration and performance evaluation of the silicon detector. In this study, we aim to investigate the utility of these materials and methods for a radioxenon detection system to achieve higher energy resolution while minimizing memory effects compared to conventional systems that employed plastic scintillator detectors. Our results demonstrate a significantly improved energy resolution of 7.8% (factor of ~ 3 × compared to plastic detectors) at the 129 keV conversion electron peak of 131mXe. The improved system is a foundation for the development of operational systems with optimized geometry for the discrimination of radioxenon isotopes.
