Since 1990 our Institute has been conducting Be-7 measurements in the atmosphere in order to use it as a tracer for air coming from the upper layers of the atmosphere and for the stratospheric ozone. In this paper we present the results on Be-7 measurements and ozone concentrations obtained with a one-year monitoring campaign carried out in Sondrio, an alpine town in Northern Italy. For a few interesting events correlations between beryllium and ozone is observed. Be-7 reveals itself as a good marker which reaches ground level during particularly rare events such as stratospheric intrusions.
