Radiocesium released from the Fukushima Daiichi nuclear power plant (FDNPP) and deposited in the terrestrial environment has been transported to the sea through rivers. To study the long-term effect of riverine transport on the remediation process near the FDNPP, a monitoring project was initiated by the University of Tsukuba. It was commissioned by the Ministry of Education, Culture, Sports, Science, and Technology, and the Nuclear Regulatory Commission in June 2011, and was taken over by the Fukushima Prefectural Centre for Environmental Creation from April 2015. The activity concentration and monthly flux of radiocesium in a suspended form were measured in the project. This provides valuable measurement data to evaluate the impact of the accidentally released radiocesium on residents and the marine environment. It can also be used as verification data in the development and testing of numerical models to predict future impacts. Measurement(s) Cesium-137 Gamma Radiation • Cesium-134 Gamma Radiation • Latitude • Longitude • grain size • radiocesium flux • radioactivity concentration Technology Type(s) gamma-ray spectroscopy • GPS navigation system • laser diffraction particle size analyzer • Calculation Factor Type(s) geographic location Sample Characteristic - Environment suspended sediment Sample Characteristic - Location Abukuma River • Fukushima Prefecture • Miyagi Prefecture Machine-accessible metadata file describing the reported data: https://doi.org/10.6084/m9.figshare.13055315 [ABSTRACT FROM AUTHOR]
