POTRE-H - A DYNAMIC-MODEL FOR RADIONUCLIDE TRANSPORT IN AGRICULTURAL ECOSYSTEMS

This paper presents a dynamic compartment model that simulates the tra nsfer of radionuclides through components of agricultural systems foll owing deposition to ground, and predicts the resulting concentrations in food products. The system of linear differential equations correspo nding to this model was solved analytically for release in the dormant season, before or after sowing, and for release in the growing season as a single or time dependent deposition. Model predictions have also been compared with levels I-131 and Cs-137 in grass and milk resultin g from the Chernobyl accident.
