对朝鲜半岛福岛核事故现场释放的放射性羽流的路径和放射性影响进行了研究。 2011年3月28日，韩国所有12个区域监测站首次观测到I-131，4月7日气溶胶中最高活度浓度为群山I-131为3.12 mBq/m(3)、釜山Cs-134为1.19 mBq/m(3)、Cs-137为1.25 mBq/m(3)。 2011年。在干和湿沉积样品中也检测到了这些放射性核素，而在海水和海洋生物群样品中没有观察到I-131、Cs-134和Cs-137活度浓度的显着增加。 (C) 2011 Elsevier Ltd. 保留所有权利。
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 I-131 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 I-131 at Gunsan, 1.19 mBq/m(3) for Cs-134 and 1.25 mBq/m(3) for Cs-137 at Busan on April 7, 2011. These radionuclides were also detected in dry and wet deposition samples, while the significant increase of I-131, Cs-134 and Cs-137 activity concentrations were not observed in seawater and marine biota samples.
