Abstract
Two lithosequences were examined, starting from siliceous and calcareous parent material, respectively. The morphological and chemical soil properties allowed to evidentiate different evolutionary trends. Radioactivity measures on 137Cs in soils and related vegetation allowed to assess that the fate of 137Cs is different in the two pedo-environments, as a consequence of the soil properties. The radionuclide contents are higher in calcareous soils and are related to the organic matter content and the CEC.
