| Abstract | River water samples were collected at the midstream of the Abukuma River for five and seven times during high-flow events in July 2018 and October 2018, respectively. Suspended solids and filtered water samples were measured for 137Cs concentration by a Ge semiconductor detector in Fukushima University and for 129I concentrations derived from analyses of 129I/127I atomic ratio with an Accelerator Mass Spectrometry and of 127I with an Induced Coupled Plasma-Mass Spectrometry in University of Tsukuba. Details of river water samples and 137Cs measurements are found in [Wakiyama, Y., Konoplev, A., Thoa, N., Niida, T., Tsukada, H., Takase, T., Nanba, N., Golosov, V., Zheleznyak, M., 2022.
