Analysis of environmental fate of radiocesium in the Abukuma River basin for 30 years after the Fukushima Dai-ichi Nuclear Power Plant accident

We evaluated the environmental fate of $^{137}$ Cs in the Abukuma River Basin from 2011 to 2040 by using a distributed radiocesium prediction model. The model well reproduced interannual variations in the concentration of $^{137}$ Cs in the suspended sediment and the total outflow of $^{137}$ Cs at Iwanuma near the estuary. Thirty years after the Fukushima Daiichi Nuclear Power Plant accident, it was estimated that the concentration of $^{137}$ Cs in the suspended sediment decreased to 1.9% of the concentration in the earliest phase after the accident and the total outflow of $^{137}$ Cs was equivalent to 4.6% of the initial deposition in the Abukuma River basin.
