Global radioactivity monitoring for the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) includes the four xenon isotopes Xe, Xe, Xe and Xe. These four isotopes are serving as important indicators of nuclear explosions. The state-of-the-art radioxenon emission inventory uses generic release estimates for each known nuclear facility. However, the release amount can vary by several orders of magnitude from year to year. The year 2014 was selected for a single year radioxenon emission inventory with minimized uncertainty. Whenever 2014 emissions reported by the facility operator are available these are incorporated into the 2014 emission inventory. This paper summarizes this new emission inventory. The emissions are compared with previous studies. The global radioxenon emission inventory for 2014 can be used for studies to estimate the contribution of this anthropogenic source to the observed ambient concentrations at IMS noble gas sensors to support CTBT monitoring activities, including calibration and performance assessment of the verification system as described in the Treaty as well as developing and validating methods for enhanced detection capabilities of signals that may indicate a nuclear test. One specific application is the 1st Nuclear Explosion Signal Screening Open Inter-Comparison Exercise announced end of 2021.
用于《全面禁止核试验条约》（CTBT）核查的全球放射性监测涵盖四种氙同位素，即Xe、Xe、Xe和Xe。这四种同位素是核爆炸的重要指标。最新的放射性氙排放清单采用了每个已知核设施的通用释放量估算值。然而，释放量每年可能相差几个数量级。2014年被选为不确定性最小的单一年度放射性氙排放清单。只要设施运营商报告的2014年排放量可用，就会将其纳入2014年排放清单。本文总结了这一新的排放清单。并将排放量与之前的研究进行了比较。2014年的全球放射性氙排放清单可用于相关研究，以估算这一人为源对国际监测系统（IMS）惰性气体传感器观测到的环境浓度的贡献，以支持《全面禁止核试验条约》的监测活动，包括如该条约所述的核查系统的校准和性能评估，以及开发和验证增强可能表明核试验信号检测能力的方法。一个具体应用是2021年底宣布的首次核爆炸信号筛选公开比对演习。
