We investigated the controlling factors of radiocesium derived from the nuclear accident in each river systems in Fukushima Prefecture and the surrounding area. Dissolved Cs concentration / Cs deposition ratio tended to be higher in the Tone River and lower in the Natsui River than in the Abukuma River. Dissolved Cs concentration generally decreases exponentially, but the half-life is shorter in the Natsui River and longer in the Tone River than in the Abukuma River.
