Abstract
Measurements of 7Be and 210Pb in atmospheric air (1 m above the ground) have been carried out each week over one and a half year period. The method used to determine 7Be and 210Pb activities is based on the total amount of radioactive aerosols filtered from the air. The activities of 7Be and 210Pb were determined by a hyper-pure germanium detector using standard gamma-spectrometry. The average weekly concentrations of 7Be were in the range of 1.21-12.1 mBq.m-3 and for 210Pb in the range of 0.8-2.4 mBq.m-3. The weekly variations were discussed in relation to various meteorological factors. It can be said that our results showed a prevailing influence of weekly average temperature for 7Be concentration and the weight of aerosols and wind speed for 210Pb oncentrations.
