The purpose of the paper is to survey the level of radioactive contamination due to the Japan Fukushima nuclear accident in Lanzhou.The radionuclide 131I,137 Cs,134 Cs and 136Cs leaked in Fukushima nuclear accident in atmosphere aerosols,drinking water,vegetable and milk in Lanzhou were detected.The radionuclide leaked in the accident didn' t be detected in drinking water,vegetable and milk.The value of the gross α radioactivity and gross β radioactivity of drinking water in Lanzhou was below the limits of national standard.The radioactive contamination due to the Japan Fukushima nuclear accident did not impact on public health in Lanzhou.%论文调查了日本福岛核事故导致的兰州地区放射性污染情况,监测了兰州地区大气气溶胶、自来水、黄河水、蔬菜、牛奶中的核事故泄漏放射性核素,并监测自来水、黄河水的总α放射性、总β放射性.测量了兰州地区大气气溶胶中来自福岛核电站泄漏放射性核素131I、137Cs、134Cs、136Cs,结果在采集的自来水、黄河水、蔬菜、牛奶样品中未检测出核事故泄漏放射性核素,自来水、黄河水样品的总α放射性、总β放射性监测结果均低于国家生活饮用水卫生标准中的限值.由此可知日本福岛核事故导致的兰州地区放射性污染不会对公众健康造成影响.
