| Popis: | Weekly measurements of air 7Be concentrations (n = 769) were performed in the years 1992–2010 in Bialystok (north-eastern Poland) using gamma spectrometry. The arithmetic mean (AM) concentration of 7Be was 2.51 mBq m−3, and the median (M) was 2.24 mBq m−3 (range 0.47–7.81 mBq m−3). The observed 7Be concentrations were within the range of levels recorded in Europe. Typical seasonal variability was observed. Concentrations of 7Be in the warm season (May, June, July) were almost twice as high as those in the cold season (November, December, January). A correlation was found between weekly 7Be concentrations and mean weekly values of relative humidity, temperature, and wind speed throughout the observation period. Pearson's correlation coefficients were −0.63, p The correlation coefficient between sunspot number and mean annual 7Be concentrations in the air in the years 1992–2010 was −0.609. |
