中文摘要:

目的汇总分析日本福岛核电站事故发生后我国沿海城市和主要内陆城市食品和饮用水放射性的抽样监测结果,评价是否对我国居民的健康造成影响。方法根据国家标准方法,制定应对日本福岛核事故对我国食品和饮用水的监测方案,统一数据报送格式,对数据进行对比分析。结果 4月2日北京露天生长菠菜样品中,监测到极微量的人工放射性核素¹³¹I,此后在全国范围内10种露天生长的蔬菜中也检测出¹³¹I,最高值为菠菜样品3.1 Bq/kg,到5月初未再检测出。牛奶、海产品和饮用水样品中未检测到人工放射性核素。结论监测到的蔬菜中¹³¹I来自日本福岛核电站事故释放,与此次事故期间欧洲一些国家食品中的的¹³¹I水平相一致,远低于1986年切尔诺贝利核电站事故时我国蔬菜中¹³¹I活度,其对公众所致吸收剂量极其微小,不会对我国境内公众造成影响。

英文摘要:

Objective To summarize the analytical results of radioactivity in the food and drinking water nationwide following the Fukushima nuclear accident, and to evaluate its possible contamination to the public health in China. Methods According to the national standard methods and IAEA, FDA correlative references,the scheme was established on sampling and measurements in food and drinking water after the breakout of the accident. The quality control was requested on the sampling, analyses and data report. Results Trace artificial radioactive isotope of ¹³¹I was measured in spinach samples on 2 April 2011 in Beijing. Subsequently ¹³¹I was found in 10 kinds of growing leaves vegetables (open field) nationwide. The maximum detectable activity of ¹³¹I in vegetables was about 3.1 Bq/kg. Since 3 May 2011, the concentration of ¹³¹I has been below the detection limits. No artificial radionulide was detectable in all of milk, drinking water and marine products samples during March to December, 2011. Conclusions The food and drinking water measurements in China following the Fukushima nuclear accident denoted that the minor amounts of ¹³¹I in vegetables might result in very low absorbed dose and induce no impact on human health. The maximum detectable activity of ¹³¹I in vegetables was close to that reported in European countries, and much less than that measured in China immediately after the Chernobyl accident in 1986.
