Abstract

Abstract To draw the balance of anthropogenic 129 I input into European soils, the concentrations of 129 I and 127 I in seven soils from Lower Saxony were analyzed down to a depth of 250 cm. In comparison with pre-nuclear soils and Ukrainian soils, we detected a significant anthropogenic input of 129 I. Considering the different time periods for the input of 129 I and 127 I it was possible to assess the dynamics of sorption processes which dominate migration and accumulation. Anthropogenic 129 I was successfully used as a tracer for a clarification of the migration processes of trace elements in soils.
