    摘要：目的通过对一起来自日本入境人员放射性超标的调查，分析日本核泄漏后扩散的因素、对环境污染影响的范围及对人群可能造成的损伤。方法对入境放射性超标人员进行现场流行病学调查、气象流行病学分析，辐射损伤诊断和除辐射污染处理。结果2名放射性超标人员经专用的辐射防护洗发、沐浴液进行全身淋浴去污，体表外恢复正常，对周围人群和环境无影响，其中1名人员甲状腺区及正前胸腺区γ射线值仍高达4μsv/h，需服用碘片。结论该起入境人员放射性超标事件是由日本核泄漏引起，无锡机场口岸在日常检测中发现了核污染情况，进行有效处理后未构成对环境、周围人群的危害，确保了国境口岸安全、出入境人员健康和社会稳定。

    Abstract:   Objective  To investigate the excessive radioactive events of entry Japaneseat Wuxi airport, and to analyze the diffusion factors after theJapanese nuclear leakage, the scope of influence of pollution tothe environment and the probable damage to the people. Methods   Field epidemiology investigation,meteorological epidemiological analysis, radiation damage diagnosisand treatment of radioactive contamination to radioactive excessiveentry people were conducted.  Results   Two cases ofradioactive excessive staff took whole body shower with thededicated radiation protection of shampoo, shower liquid fordecontamination. Body surface indices returned to normal levels,but also the surrounding population and enviroment will not haveany negative impact. One of them need to take iodine tablets, ther-ray values were still up to 4 μsv/h at thyroid area andprothoracic area.   Conclusion   The entrypersons over radioactive incident were caused by Japanese nuclearleakage. Wuxi airport found inspection of nuclear pollution in thedaily. It doesn’t constitute a hazard to crowd around theenvironment after effective treatment. It is important to ensurethe safety of frontier ports, the health of the entry-exitpersonnel and the stability of society.
