The radioactivity concentrations for(90)Sr and(137)Cs in soil samples collected near Fukushima Daiichi nuclear power station were investigated. The depth profile of(137)Cs from the surface soil to 20 cm showed a typical decreasing tendency, that is, high radioactivity from the surface down to 5 cm due to the strong sorption of specific minerals. After deposition of(90)Sr,Sr-90 has migrated to deeper soil layers in the past 5 years compared to(137)Cs. This tendency was supported by the results of sequential extraction to identify the predominant sorption species, and by the sorption coefficients determined by batch-wise sorption experiments.
