Traces of (131)I, (134)Cs and (137)Cs were measured after the Fukushima nuclear accident between 23 March and 13 April 2011 in southeast Spain. The movement of the radioactive cloud toward southeast Spain was reconstructed based on the backward and forward trajectory cluster analyses. Polar maritime air masses which had originated over North America transported the radioactive plume toward the southeast Spain. Aerosols, rainwater, vegetables and cheese were analyzed to determine the radioactive risk. The highest concentrations of (131)I, (134)Cs and (137)Cs in air samples were 2.63 ± 0.12 mBq/m(3); 0.10 ± 0.03 mBq/m(3); 0.09 ± 0.02 mBq/m(3), respectively. After precipitation on April 3rd, the maximum concentrations of (131)I, (134)Cs and (137)Cs were detected in rainwater samples, 1.10 ± 0.16 mBq/L; 0.022 ± 0.003 mBq/L; 0.05 ± 0.03 mBq/L, respectively. As a consequence, (131)I was transferred to the human food chain, and found in chard and goat cheese, 0.97 ± 0.20 Bq/kg and 0.52 ± 0.08 Bq/kg, respectively. The traces of (131)I, (134)Cs and (137)Cs detected in the different samples were so low, that there is no impact on human health or the environment in Spain after the Fukushima nuclear accident.
2011 年 3 月 23 日至 4 月 13 日，在西班牙东南部检测到了福岛核事故后的 (131)I、(134)Cs 和 (137)Cs 痕迹。基于后向和前向轨迹聚类分析，重建了放射性云团向东南西班牙移动的过程。起源于北美的极地海洋气团将放射性羽流输送到西班牙东南部。分析气溶胶、雨水、蔬菜和奶酪以确定放射性风险。空气中 (131)I、(134)Cs 和 (137)Cs 的最高浓度分别为 2.63 ± 0.12 mBq/m(3)、0.10 ± 0.03 mBq/m(3)和 0.09 ± 0.02 mBq/m(3)。4 月 3 日降雨后，雨水样本中检测到 (131)I、(134)Cs 和 (137)Cs 的最大浓度分别为 1.10 ± 0.16 mBq/L、0.022 ± 0.003 mBq/L 和 0.05 ± 0.03 mBq/L。因此，(131)I 转移到人类食物链中，在菠菜和山羊奶酪中发现，分别为 0.97 ± 0.20 Bq/kg 和 0.52 ± 0.08 Bq/kg。福岛核事故后，在不同样本中检测到的 (131)I、(134)Cs 和 (137)Cs 痕迹非常低，对西班牙的人类健康或环境没有影响。
