Abstract: 

The natural radioactivity of some paleosols from carbonate and siliciclastic rocks was studied using synthetic polycarbonate plates (CR39) in some Central and Southern Italian regions. The results demonstrate that Fe/Mn nodules, which are likely to form commonly in hydromorphic soils, are capturing Uranium together with rare metallic elements which have similar ionic potential.
