A decreasing amplitude and splitting of summer maxima for 7Be has been found. The 137Cs concentration was decreasing with an effective half-life of 1.9 ± 0.3 years. The increased 137Cs and 40K levels were due to surface soil re-suspension. The mean residence time of aerosols in the atmosphere was 4.5 ± 0.9 days.
