Abstract

Since 1998, there have been improvements in the capability to detect radioxenon in air in the International Monitoring System operated by the Preparatory Commission of the Comprehensive Nuclear-Test-Ban Treaty Organization. The upgrades to both hardware and software have resulted in next-generation versions of the radioxenon systems. As part of the improvement process, this paper explores radioxenon data analysis improvements beyond the original radioxenon beta-gamma analysis equations of the net count calculation method that were first formulated in 2000. In addition, it provides recommendations to further improve analysis and refinement of 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 the radioxenon measurements.
