AB  - This study investigates the beryllium-7, lead-210 and caesium-137 activity concentrations in aerosol filter samples collected monthly along the 45°N zonal belt over 1991–2019. Sampling was performed in three locations, one in Serbia and two in Slovenia, and the Slovenian data records are published here for the first time. The activity concentrations were determined by standard gamma spectrometry. The obtained results are in general agreement with the literature data for Europe. The data sets at different sites display similarities in measurement ranges, overall means and seasonal cycles. Still, statistical tests show significant differences among the radionuclides’ concentrations across the locations. To investigate underlying processes that affect radioactivity in the surface air in this region, multivariate statistical concepts are applied to the radionuclides’ concentrations and local meteorological parameters. Discriminant analysis shows that all three sites are well separated from each other. Principal component analysis gives common pattern of interconnection between the observables: temperature has a stronger influence on the behaviour of beryllium-7 and lead-210 than that of caesium-137, but a negative correlation of the radionuclides’ concentrations with precipitation seems the strongest for caesium-137. Principal component analysis also shows local differences in the degree of relationship between the meteorological parameters and activity concentrations of the investigated radionuclides. This is an important finding for future atmospheric transport studies.

AB  - A method is presented for calculating the expected number of counts in peaks that have a large relative peak area uncertainty and appear in measured gamma-ray spectra. The method was applied to calculations of the correction factors for peaks occurring in the spectra of radon daughters. It was shown that the factors used for correcting the calculated peak areas to their expected values decrease with an increasing relative peak-area uncertainty. The accuracy of taking the systematic influence inducing the correction factors into account is given by the dispersion of the correction factors corresponding to specific peaks. It was shown that the highest accuracy is obtained in the peak analyses with the GammaVision and Gamma-W software.

Merenja su sprovedena u Beogradu, Republika Srbija, i u Ljubljani i Krškom, u
Republici Sloveniji, tokom 1991–2015 godine. Na sve tri lokacije, faktorska opterećenja
dva faktora pokazuju da je: 1) specifična aktivnost berilijuma-7 obuhvaćena faktorom 1
sa temperaturom, oblačnošću i relativnom vlažnošću; dok je 2) specifična aktivnost
olova-210 obuhvaćena faktorom 2 sa količinom padavina i atmosferskim pritiskom.
Iako je komunalitet već dva faktora veći od 0,5 za većinu posmatranih varijabli, tek
uvođenjem trećeg faktora komunalitet za specifičnu aktivnost olova-210 i atmosferskog
pritiska na sve tri merne lokacije raste na preko 0,5. Rezultati faktorske analize
pokazuju da se specifične aktivnosti berilijuma-7 i olova-210 u prizmenom sloju

pod uticajem faktora regionalnog karaktera, koji je takođe dominantan za srednju
temperaturu. Ova veza specifične aktivnosti berilijuma-7 i temperature preko dominantnog zajedničkog faktora važi i kada se broj faktora u analizi poveća na tri i četiri.
Sa druge strane, na koncentraciju olova-210, kao i na količinu padavina i atmosferski
pritisak, više uticaja ima lokalni faktor. Ova povezanost olova-210 sa druga dva

AB  - An association between the beryllium-7 and lead-210 specific activities in surface air
and meteorological parameters is investigated using factor analysis. The measurements
were conducted in Belgrade, Republic of Serbia, and Ljubljana and Krško, Republic of
Slovenia, over 1991–2015. In all the locations, the factor loadings of two factors show
that: 1) the beryllium-7 specific activity is encompassed by factor 1 together with
temperature, cloud cover and relative humidity; while 2) the lead-210 specific activity,
precipitation and atmospheric pressure are described by factor 2. Although the
communalities of only two factors are already larger than 0.5 for most of the variables,
an introduction of a third factor raises the communalities of all the variables above 0.5.
The results imply that the beryllium-7 and lead-210 are under different dominant
underlying mechanisms. The concentration of beryllium-7 seems to be primarily
influenced by a mechanism of a regional character which is also a predominant factor
for temperature. This association between the beryllium-7 specific activity and
temperature prevails even when the number of factors in the analysis is raised to three
and four. The lead-210 specific activity, on the other hand, together with precipitation
and atmospheric pressure, is under an influence of a local mechanism, but that
relationship between the variables ceases to hold when the number of factors is raised
to three, and more than 80% of the variance in the Pb-210 specific activity is explained
by one specific factor.
