High activity concentrations of several man-made radionuclides (such as (131)I, (132)I, (132)Te, (134)Cs and (137)Cs) have been detected along the Iberian Peninsula from March 28th to April 7th 2011. The analysis of back-trajectories of air masses allowed us to demonstrate that the levels of manmade radionuclide activity concentrations in the southwest of the Iberian Peninsula come from the accident produced in the nuclear power plant of Fukushima. The pathway followed by the radioactive plume from Fukushima into Huelva (southwest of the Iberian Peninsula) was deduced through back-trajectories analysis, and this fact was also verified by the activity concentrations measured of those radionuclides reported in places crossed by this radioactive cloud. In fact, activity concentrations reported by E.P.A., and by IAEA, in several places of Japan, Pacific Ocean and United States of America are according to the expected ones from the air mass trajectory arriving at Huelva province.
2011 年 3 月 28 日至 4 月 7 日期间，在伊比利亚半岛沿线检测到了几种人为放射性核素（如 (131)I、(132)I、(132)Te、(134)Cs 和 (137)Cs）的高活度浓度。对气团后向轨迹的分析表明，伊比利亚半岛西南部人为放射性核素活度浓度水平来自福岛核电站事故。通过后向轨迹分析推断出福岛放射性烟云进入韦尔瓦（伊比利亚半岛西南部）的路径，这一事实也通过在穿越该放射性云的几个地点测量到的这些放射性核素的活度浓度得到验证。事实上，美国环保署和国际原子能机构在日本、太平洋和美国的多个地点报告的活度浓度与到达韦尔瓦省的气团轨迹所预期的活度浓度相符。
