Abstrakt:
The concentrations of radioactive nuclides of 210Pb, 7Be, 137Cs and 40K in
Bratislava atmosphere obtained during 2001 - 2003 period are presented.
Average value of cosmogenic 7Be concentration in 2002 year in low level
atmosphere was 2,1 mBq.m-3 and its concentration shows seasonal variations.
Isotope 210Pb is interesting especially from the radio-hygienic point of view.
Its average value of concentration in 2002 year is 0,8 mBq.m-3. Volume
activity of antropogenic 137Cs in low level atmosphere is at level 1 uBq.m-3.
Also mean activity of primordial 40K in aerosols achieved very low values,
about 9 uBq.m-3. The qualitative analysis of element composition of exposed
aerosol filters was analyzed using radionuclide X-ray fluorescence method.
The relations between investigated components of aerosol part of atmosphere
were also discussed
