摘要：

A dynamic compartment model was developed to estimate Cs-137 concentrations in both seawater and sediment that had been released in the TEPCO's Fukushima Daiichi Nuclear Power Plant 2011 accident. The model parameters were set from the best fitting of the results observed at the two closest sampling stations to the FDNPP site, then applied these parameters to three other stations located about 15-43 km away from the FDNPP. The Cs-137 concentrations in seawater and sediment estimated by the developed model agreed well with observation results for these stations.
