The purpose of the study is to explore the sorption behaviour of anthropogenic radionuclides in the Vltava River catchment in the Czech Republic, which could be influenced by an assumptive severe nuclear accident. Radionuclide sorption was described by distribution coefficients between water and sediment or suspended solids, respectively. Then, possible correlations between radionuclide sorption and sediment properties were investigated using simple and multiple regressions. The sorption of radionuclides was affected by sediment granularity and mineralogical composition, each radionuclide having its group of influencing sediment parameters.

河流沉积物和悬浮固体上人为放射性核素的吸附：对沉积物成分的依赖

该研究的目的是探索捷克共和国伏尔塔瓦河集水区人为放射性核素的吸附行为，该行为可能受到假设性严重核事故的影响。放射性核素吸附分别通过水和沉积物或悬浮固体之间的分配系数来描述。然后，使用简单和多元回归研究了放射性核素吸附和沉积物性质之间可能的相关性。放射性核素的吸附受沉积物粒度和矿物组成的影响，每种放射性核素都有其影响沉积物参数的一组。
