Using thin section autoradiography to detect the Uranium content of Fe/Mn soil nodules

摘要

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.
