摘要：
Near-surface air concentrations of Be-7 and its deposition rates were measured in the atmosphere in Bratislava from 1977 to 1994. Late spring and summer maxima were observed in the near-surface air concentrations on an annual basis, Using measured deposition rates and the calculated average tropospheric content of Be-7 atoms, their mean tropospheric residence time (27-48 days) was determined. An anticorrelation between the measured Be-7 concentration and the sunspot number with correlation factor of 0.55 was observed.
