Opening Fukushima floodgates: Modelling 137Cs impact in marine biota

A numerical model was applied to simulate the transport of 137Cs released with waters which were used cool Fukushima reactors. These stored will be Pacific Ocean according Japanese government plans. The radionuclide is Lagrangian and includes interactions sediments an integrated dynamic foodweb for biota uptake. Calculations made from a conservative approach indicate that expected concentrations in marine fish would orders magnitude below those detected after accident also lower than resulting global fallout background.
