A series of (133)Xe detections in April 2011 made at the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) International Monitoring System noble gas station in Darwin, Australia, were analysed to determine the most likely source location. Forward and backwards atmospheric transport modelling simulations using FLEXPART were conducted. It was shown that the most likely source location was the Fukushima Dai-ichi nuclear power plant accident. Other potential sources in the southern hemisphere were analysed, including the Australian Nuclear Science and Technology Organisation (ANSTO) radiopharmaceutical facility, but it was shown that sources originating from these locations were highly unlikely to be the source of the observed (133)Xe Darwin detections.
2011 年 4 月，在澳大利亚达尔文全面禁止核试验条约组织（CTBTO）国际监测系统稀有气体站进行了一系列（133）Xe 检测，对其进行了分析以确定最可能的源位置。使用 FLEXPART 进行了向前和向后大气输送模拟。结果表明，最可能的源位置是福岛第一核电站事故。还分析了南半球的其他潜在源，包括澳大利亚核科学与技术组织（ANSTO）放射性药物设施，但结果表明，源自这些位置的源极不可能是观察到的（133）Xe 达尔文检测的源。
