| Abstract | The Fukushima Dai-ichi Nuclear Power Plant accident caused a release of radionuclides covering a significant area in Fukushima Prefecture, Japan. In the current work the radio-caesium concentrations observed in some points of Namie Town between 2018. June. and 2019. September in river water, and river sediment are being presented. The observed concentrations were up to for 205.9 ± 9 mBq/L for 137Cs in unfiltered water, while the sediment had a maximum of 4041 ± 2 Bq/kg-dry for 137Cs. In many cases the water and aerosol samples had activity concentrations below the detection limit. These values decreased compared to the year 2017 for the same area.
