    Spectrocolorimetric, geochemical and radiocesium properties of source material and sediment collected after the 2019 typhoons in Fukushima coastal rivers (Japan) (2020)

    Description: Spectrocolorimetric properties analysed with a portable diffuse reflectance spectrophotometer (Konica Minolta CM-700d) and geochemical contents obtained with an energy dispersive X-ray fluorescence spectrometer (ED-XRF Epsilon 4) were analysed in potential source material that may supply sediment to coastal rivers draining the main Fukushima radioactive pollution plume (Japan). Three potential source materials (n=57) were considered (cropland soils ready for cultivation after the completion of the local decontamination programme; forest soils and subsurface material originating from landslides and channel bank collapse). Recent sediment lag deposits (mud drapes deposited on channel-bed sand; n=24) were collected along the main rivers draining the Mano and Niida catchments (Fukushima Prefecture, Japan) on the 29th and 30th of October 2019 after the 2019 typhoon season including typhoon Hagibis. In addition to spectrolorimetric and geochemical properties, radiocesium (Cs-137) concentrations were analysed by gamma spectrometry using Germanium Hyperpure detectors in all source and sediment samples (n=81).

    Radioactive dose rates and fallout radionuclide activities in sediment deposits along rivers draining the main Fukushima plume, Japan (2021)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: This dataset compiles all the radioactive dose rates measurements and the anthropogenic fallout radionuclides analysed in recent sediment deposits collected in the coastal catchments draining the main radioactive plume of Fukushima, Japan (2011-2020). Gamma-emitting fallout radionuclides activities (Cs-137, Cs-137, Ag-110m) were determined by gamma spectrometry using HPGe detectors (Canberra/Ortec), and activities were decay-corrected to the sampling date. Uncertainties reached ca. 5-10% on Cs-134 and Cs-137 activities, and ca. 15-20% on Ag-110m activities at the 95% confidence level. Radiation dose rates were systematically measured in the field (at 1-cm height from the soil) using a radiameter (LB123 D-H10, Berthold Technologies) in recent sediment drape deposits and in nearby soils along rivers (i.e. in a 10 to 20 m wide area along rivers). This data was collected in the framework of the TOFU (Agence Nationale de la Recherche; grant no. ANR-11-JAPN-001) and the AMORAD (Programme des Investissements d'Avenir; grant no. ANR-11-RSNR-0002) projects. The support of Centre Nationalde la Recherche Scientifique (CNRS, France) and Japan Society for the Promotion of Science (JSPS) is also gratefully acknowledged (grant no. PRC CNRS-JSPS 2019-2020, no. 10; CNRS International Research Project - IRP -MITATE).
