Abstract
Near-surface air concentrations of7Be 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 of7Be atoms, their mean tropospheric residence time (27–48 days) was determined. An anticorrelation between the measured7Be concentration and the sunspot number with correlation factor of 0.55 was observed.
