Beryllium-7 (7Be) is a natural radionuclide originated from interaction of cosmic rays with atmosphere, which enters continuously into the ecosystems mainly through wet deposition; therefore dry deposition can be neglected . In order to use 7Be as an indicator of environmental processes it is necessary to know its deposition rate. The aim of this research is to investigate the 7Be content in rains, relationships with precipitation regime, and assess the 7Be deposition in soil and its seasonality
