“…The most promising avenue is to increase the detector resolution to reduce the interferences and background during the measurement. Solutions exploiting increased energy resolution are being pursued through different scintillation materials, configurations, and solid state detectors [31].…”

Since 1998, there have been improvements in the capability to detect atmospheric radioxenon in the International Monitoring System operated by the Preparatory Commission of the Comprehensive Nuclear-Test-Ban Treaty Organization. The upgrades have resulted in next-generation versions of the radioxenon systems. This paper explores radioxenon data analysis improvements beyond the original radioxenon beta-gamma analysis equations that were formulated in 2000. Additionally, it provides recommendations to further improve analysis and refine the equations. The areas of improvement are described in terms of equations, physical detectors, and field-testing. These recommendations are provided with the intention of improving accuracy and precision of radioxenon measurements.

“…The GBL15 noble gas laboratory uses a Swedish Automatic Unit for Noble Gas Acquisition (SAUNA) to purify and measure radioxenon in environmental gas samples. This system uses a near 4π β − γ coincidence detection system consisting of BC404 plastic scintillator (for electron detection) and sodium iodide (NaI(Tl)) for photon detection [7,8]. Similar systems are used throughout the IMS to collect and monitor radioxenon in the atmosphere.…”

“…Radioxenon monitoring is a major component of the verification regime due to its ability to characterize an event as containing fissile material. Over the years, many detectors have been developed and tested to improve radioxenon detection capabilities [1]. A common technique for measuring radioxenon is beta-gamma coincidence detection.…”

Radioxenon detection is an important component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty. We developed and validated a new model in MCNPX-PoliMi to simulate the decay of various radioxenon isotopes and the detector response of a variety of detector types. The model was validated using calibration data from a plastic and NaI(Tl) beta-gamma coincidence detector and the results are presented. The results of this validation show that this model can also be used as a tool to produce training spectra and as a method to calibrate radioxenon detection systems.
