dc.description.abstract | We report an inter-comparison of eight models designed to predict the radiological exposure of radio-nuclides in marine
biota. The models were required to simulate dynamically the uptake and turnover of radionuclides by marine organisms.
Model predictions of radionuclide uptake and turnover using kinetic calculations based on biological half-life (TB1/2) and/or
more complex metabolic modelling approaches were used to predict activity concentrations and, consequently, dose rates of 90Sr,
131I and 137Cs to fish, crustaceans, macroalgae and molluscs under circumstances where the water concentrations are changing
with time. For comparison, the ERICA Tool, a model commonly used in environmental assessment, and which uses equilibrium
concentration ratios, was also used. As input to the models we used hydrodynamic forecasts of water and sediment activity
concentrations using a simulated scenario reflecting the Fukushima accident releases.
Although model variability is important, the intercomparison gives logical results, in that the dynamic models predict
consistently a pattern of delayed rise of activity concentration in biota and slow decline instead of the instantaneous equilibrium
with the activity concentration in seawater predicted by the ERICA Tool. The differences between ERICA and the dynamic models
increase the shorter the TB1/2 be-comes; however, there is significant variability between models, underpinned by parameter and
methodological differences between them.
The need to validate the dynamic models used in this intercomparison has been highlighted, partic-ularly in regards to
optimisation of the model biokinetic parameters. | es |
