Cs-137, 210Pbex, and 7Be have successfully been used as tracers of soil redistribution.
The natural fallout radionuclide 7Be is used as a tracer allowing estimates of soil redistribution on an event-based time scale.
In this paper, we review the literature concerning Pu in soil and of current attempts to use this tracer to estimate rates of soil redistribution.
The most reliable tracers for soil ingestion estimates were aluminum, silicon, and yttrium.
This, along with the nearly constant production of Rn in soils and short residence time (several days) makes Rn an excellent tracer of physical processes that drive soil gas exchange.
ML minerals indicate chemical weathering and also act as tracers used to identify source areas of soil parent materials.
Erosion tracer techniques are capable of quantitatively determining spatial distribution of soil erosion.
The 18O/16O ratio of CO2 is a potentially powerful tracer of carbon dioxide fluxes from the soil to the atmosphere, which is influenced by complex interactions involving both biotic and abiotic soil processes.
For this, we carried out a field tracer experiment and sprinkled chloride enriched solution over two areas of soil (2 × 66 m2) in March, 2006.
