2011年3月福岛核电站事故发生后，西安对气溶胶放射性核素(131I、134Cs、137Cs)和气态放射性氙气(133Xe)进行了监测，中国说。根据中国国家标准，可归因于福岛排放的额外年有效剂量远低于自然辐射的公共年有效剂量。监测结果与其他国家的数据以及1986年切尔诺贝利核事故后西安观测到的放射性核素浓度进行了比较。调查了释放的放射性核素从福岛到西安的可能运输途径。太平洋地区出现的反气旋和放射性核素释放周期的延长使测定的输送路径变得复杂，但烟柱和东风气流的辐散明显地将首批放射性核素带到了西安。
Aerosol radionuclides (131I,134Cs,137Cs) and gaseous radioactive xenon (133Xe) were monitored at Xi’an, China following the accident at the Fukushima nuclear power plant in March 2011. The additional annual effective dose attributable to the Fukushima emissions was much lower than the public annual effective dose from natural radiation, according to Chinese national standards. The monitoring results were compared with data from other countries as well as with the radionuclide concentrations observed in Xi’an after the Chernobyl nuclear accident in 1986. Possible transport pathways of the released radionuclides from Fukushima to Xi’an were investigated. The occurrence of an anticyclone in the Pacific Ocean region and the extended period over which the radionuclides were released made the determination transport pathways complex, but divergence in the plume and easterly flow evidently brought the initial suite of radionuclides to Xi’an.
