Depth distribution of 137Cs, 134Cs, and 131I in soil profile after Fukushima Dai-ichi Nuclear Power Plant Accident.
TLDR
The depth distribution of the deposited radionuclides in the cultivated soil profile was investigated in one of the most contaminated area after FDNPP accident and the positive relationship was found between clay content of topsoil and the h(0) of (137)Cs.
Evolution of overland flow after a severe forest fire, Point Reyes, California
Abstract Forest fires on granitic soils often increase overland flow and erosion. Runoff generation was monitored on a small hillslope plot on Mt. Vision near Point Reyes Peninsula, California, after
Radiocesium transfer from hillslopes to the Pacific Ocean after the Fukushima Nuclear Power Plant accident: A review.
TLDR
A review of results regarding the fundamental processes and dynamics that govern radiocesium transfer from hillslopes to the Pacific Ocean published in the literature within the first four years after the FDNPP accident demonstrates that characterizing the different mechanisms and factors driving radiocsium transfer is important.
The role of subsurface runoff through bedrock on storm flow generation
The influence of bedrock subsurface flow on storm runoff generation was investigated in Japan in two regions in Japan underlain by three bedrock types. One region, with approximately 2500 m of
Vertical distribution and temporal changes of 137Cs in soil profiles under various land uses after the Fukushima Dai-ichi Nuclear Power Plant accident.
TLDR
Monitoring the vertical distribution of (137)Cs in soil profiles under eight different land uses for the 2 y after the Fukushima Dai-ichi Nuclear Power Plant accident indicated that the initial distribution would be influenced by the Cs fixation ability of soil, and the penetration process of water and particles in soils.
Interception of the Fukushima reactor accident‐derived137Cs, 134Cs and 131I by coniferous forest canopies
[1] The Fukushima Daiichi nuclear power plant accident resulted in extensive radioactive contamination of the surrounding forests. In this study, we analyzed fallout 137Cs, 134Cs, and 131I in
Initial flux of sediment-associated radiocesium to the ocean from the largest river impacted by Fukushima Daiichi Nuclear Power Plant
TLDR
The Abukuma Basin is the largest river system affected by fallout from the Fukushima Daiichi Nuclear Power Plant event and an estimated 84 to 92% of the total radiocesium transported in the basin's fluvial system was carried in particulate form.
Size distribution studies of 137Cs in river water in the Abukuma Riverine system following the Fukushima Dai-ichi Nuclear Power Plant accident.
TLDR
The data acquired in this study give an overview of the radiological situation for Fukushima including temporal and spatial variation of radiocaesium in a natural riverine system, within a few years after the accident.
Determinant factors of sediment graphs and rating loops in a reforested watershed
Summary Sediment graphs and hydrographs were analyzed in a small, high-gradient reforested watershed in Mie Prefecture, Japan, which was instrumented to measure discharge and sediment transport. The
Detailed deposition density maps constructed by large-scale soil sampling for gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant accident.
TLDR
Soil deposition density maps of gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident were constructed on the basis of results from large-scale soil sampling, and the radiation doses from radioactive cesium were found to be much higher than those from the other radioactivenuclides.
