Distribution of dissolved and particulate radiocesium concentrations along rivers and the relations between radiocesium concentration and deposition after the nuclear power plant accident in Fukushima
TL;DR: The results showed a strong correlation between deposited (137)Cs and dissolved ( 137)Cs, and a relatively weak correlation between depositing (137]Cs and particulate (137)'s concentration for each river, but if the particulates concentration was converted to (136)Cs concentration per unit weight of suspended solid, the values showed astrong correlation.
Journal ArticleDOI
Assessing cost and effectiveness of radiation decontamination in Fukushima Prefecture, Japan.
Tetsuo Yasutaka,Wataru Naito +1 more
TL;DR: The results indicate that technologies for reducing the volume of decontamination waste and removed soil should be considered to reduce storage costs and that further discussions about forestDecontamination policies are needed.
Journal ArticleDOI
Behavior of dissolved radiocesium in river water in a forested watershed in Fukushima Prefecture
TL;DR: In this paper, the authors investigated the role of organic material leaching from flooded areas in the generation of dissolved radiocesium in river water in a high-dose-rate forest watershed in Fukushima Prefecture.
Journal ArticleDOI
Geo-environmental issues induced by the 2011 off the Pacific Coast of Tohoku Earthquake and tsunami
TL;DR: In this article, the current status on the generation, clearance, and treatment and utilization of disaster debris and tsunami deposits from geotechnical and geo-environmental viewpoints is summarized.

TL;DR: In this article, a method for concentrating and measuring radiocesium (134C and 137C) dissolved in fresh water using nonwoven fabric impregnated with Prussian blue (PB) as a radiocescium absorber in combination with gamma-ray spectrometry using a germanium (Ge) detector was developed.
