Abstract

Radioactive cesium rich microparticles (CsMPs) could partially increase ¹³⁷Cs concentration of the samples collected from the environment after the Fukushima Daiichi Nuclear Power Plant accident. In this study, we investigated the vertical distribution of CsMPs in soils collected from Fukushima Prefecture, Japan. The distribution of CsMPs was relatively large in the soil surface layer. However, the proportion of CsMPs in the RCs concentration at each soil depth was not large, less than 10%.

福岛土壤中富放射性铯微粒的垂直分布

福岛第一核电站事故发生后，从环境中采集的样本中富含放射性铯的微粒子（CsMPs）可能会部分增加 137Cs 的浓度。在这项研究中，我们调查了从日本福岛县采集的土壤中 CsMPs 的垂直分布情况。在土壤表层，硫化镉的分布相对较大。然而，在每个土壤深度的 RCs 浓度中，CsMPs 所占的比例并不大，小于 10%。
