produced primarily by the bombardment of the earth's atmosphere by cosmi crays within the troposphere and stratosphere
has a similar environmental chemical behavior as137Cs and 210Pb. With a hal-f life of 53.3 days
7Be can be used to document short-term rates
patterns and seasonal variations of soil redistribution or sediment deposition representing the influences of a specific landuse or a particular event in a period of precipitation. Potential application of the information on soil erosion and redistribution provided by 7Be measurements can clearly include the validation and calibration of distributed event-induced soil erosion and sediment delivery models. 7Be technique
a potential alternative to 137Cs and 210Pb in situations where information on short-term or event-based soil erosion is required
is considerably promising in soil erosion tracing
such as soil erosion on debris from project construction.
