The pathway and radiological impact of the radioactive plume released at the Fukushima nuclear accident site on the Korean Peninsula has been studied. On March 28, 2011, only (131)I was first observed at all 12 regional monitoring stations in Korea, and the highest activity concentrations in aerosol were 3.12 mBq/m(3) for (131)I at Gunsan, 1.19 mBq/m(3) for (134)Cs and 1.25 mBq/m(3) for (137)Cs at Busan on April 7, 2011. These radionuclides were also detected in dry and wet deposition samples, while the significant increase of (131)I, (134)Cs and (137)Cs activity concentrations were not observed in seawater and marine biota samples.
研究了福岛核事故现场释放的放射性羽流在朝鲜半岛的路径和放射性影响。2011 年 3 月 28 日，韩国所有 12 个地区监测站首次观测到（131）I，2011 年 4 月 7 日，在群山气溶胶中（131）I 的最高活度浓度为 3.12 mBq/m³，在釜山（134）Cs 和（137）Cs 的最高活度浓度分别为 1.19 mBq/m³和 1.25 mBq/m³。这些放射性核素也在干、湿沉降样本中被检测到，而在海水和海洋生物样本中未观察到（131）I、（134）Cs 和（137）Cs 活度浓度的显著增加。
