ABSTRACT


The atmospheric behavior of 7Be-aerosols in association with atmospheric pollutants was studied by using 1-ACFM Andersen type cascade impactors. The activity of 7Be, a radionuclide of cosmogenic origin, determined by gamma-ray spectrometry (Eγ = 0.477 MeV), was largely associated with submicron aerosol particles in the accumulation mode (0.4–2.0 μm). The activity median aerodynamic diameter (AMAD) of 7Be-aerosols ranged from 0.62 to 1.00 μm (average 0.80 μm). The geometric standard deviation, σg ranged from 1.87 to 2.50 (average 2.22). Low AMAD values of 7Be-aerosols have been observed at locations characterized with relatively low pollution. Some dependency of AMADs on height from the ground surface varied from zero to 1201 m has also been observed with high AMAD values in zero height where the pollution was high and low AMAD values in high elevation where the pollution was low. In near marine environment where the airport is located, an area with additional pollution, the activity size distribution of 7Be-aerosols was observed in higher size range of aerosol particles (0.82–0.90 μm).
