Beryllium-7 is environmental or fallout radionuclide with a half-life of 53. 3 days
which is produced primarily by the bombardment of the earth atmosphere by cosmic rays. It is subsequently transported into the soil surface by wet and dry deposition. It is rapidly and strongly absorbed by soil particles and redistributes with soil particles. Therefore
it 7Becan be used as a tracer for studying soil erosion. The recent progress in the use of the environmental radionuclide beryllium-7 (7Be) for investigating rates of soil erosion and deposition is introduced
and suggestions for applying it into soil erosion are proposed.
