dc.description.abstract | A numerical model which simulates the adsorption of radionuclides by migrating bluefin tuna in the Mediterranean Sea is described, in order to determine the level of contamination of these fish after a hypothetical nuclear
accident and thus be able to assess the possible impact on human consumption. A 4–species foodweb model is
incorporated into a Lagrangian model describing physical transport (advection, mixing, radioactive decay and
interactions of radionuclides with sediments). Tuna is the last trophic level in the foodweb model and the
equation providing the temporal evolution of radionuclide concentration in its flesh is solved along the fish
trajectories, which were obtained through electronic tagging of fishes. The model was applied to the western
Mediterranean, where several worst–case hypothetical accidents were simulated, both from a coastal nuclear
power plant and from a vessel. Resulting 137Cs concentrations in migrating tuna were similar, or slightly higher,
than reported background concentrations in these fishes and well below established safety levels. Maximum
calculated concentrations in tuna flesh is in the order of 1 Bq/kg (wet weight). This is due to the rapid movement
of the fishes, which spend only limited time over the most contaminated spots. | es |
