  • Modelling and study of the mechanisms of the transfer of radioactive material from terrestrial ecosystems to and in water bodies around Chernobyl


The following experimental studies were carried out:

Radionuclides migration and transformation including:
hot particles as a specific feature of the Chernobyl accident;
radiocaesium sorption-desorption in soils and bottom sediments;
specific aspects of radionuclide behaviour in peat bog areas;
the role of suspended matter in radionuclide transport in rivers and reservoirs;
Uptake and elimination of radionuclides in fish including:
general radioecological description of sites;
field studies of fish-size effect in (137) Cs accumulation;
field studies on seasonal and age changes in fish diet;
experimental studies on the possible effect of fish size on the radiocaesium biological half-life;
experimental studies on some environment parameters that may affect radiocaesium biological half-life;
conclusions for modelling.

Modelling was used in the following cases:
modelling radionuclide solid-liquid distribution;
modelling radionuclide transport in catchment-lake systems;
modelling of suspended radionuclide transport through a river-reservoir system;
modelling radionuclide migration in peat bog areas;
methods for the estimation of key model paramters;
application of the LAKEKO lake model to explain the size-effect phenomenon observed in fish. The report includes a background discussion, considers strategy, implementation and scientific progress, and concludes with an evaluation of results and some recommendations.
