Abstract

<p>The accident at TEPCO's Fukushima Daiichi Nuclear Power Station caused by the Great East Japan Earthquake on 11 March 2011 was a nuclear accident involving the release of a large amount of radioactive substances, and much of the radioactive caesium that was released and flowed into the water system accumulated as sediment in reservoirs. In this study, the water quality of inflow and outflow water of a reservoir was investigated in a reservoir managed at a low water level in order to quantitatively understand the dynamics of radiocaesium in the reservoir. The results showed that reservoirs managed at low water levels act as a source of both suspended- and dissolved-form caesium, with suspended-form caesium outflow being dominant. Seasonal variations were observed in the concentration of dissolved-form caesium in the effluent, which was almost the same as that in the inflow water in winter, and an increase in summer.</p>
