Vertical transport of radiocesium in surface soils: model implementation and dose-rate computation.

A mathematical model on the Radionuclide Behaviour in Soil for the study of the migration of radionuclides in undisturbed soil profile has been developed. The model has been calibrated using 134Cs and 137Cs concentrations along soil samples gathered in a natural grassland and beech wood, respectively, located in the Friuli-Venezia Giulia region (northeastern part of Italy). In these sampling sites, the external exposure due to 134Cs and 137Cs distribution along the soil profile has been also assessed.
