AB  - Mjerenja koncentracije aktivnosti radionuklida Be-7 (berilij-7), Pb-210 (olovo
210) i Cs-137 (cezij-137) u Zemljinoj atmosferi neophodna su za razumijevanje
atmosferskih procesa, kvalitete zraka i radioaktivnosti okoliša. Berilij-7 je
radioaktivni izotop koji prvenstveno nastaje interakcijom kozmičkih zraka s
atomima dušika i kisika u gornjoj atmosferi. Njegov kratki poluživot čini ga
vrijednim tragačem za atmosferske procese u relativno kratkim vremenskim
razdobljima. Olovo-210 je radioaktivni izotop čiji je primarni izvor u atmosferi
raspad plina radona. S dužim poluživotom od Be-7, pogodan je za proučavanje
dugotrajnijih atmosferskih procesa. Cezij-137 je, s druge strane, antropogeni
radioizotop s vremenom poluraspada čak i dužim od onog Pb-210, što ga
čini dobrim dugoročnim ekološkim tragačem. Nedavno je uspostavljena baza
podataka za praćenje radioaktivnosti tla u zraku (GRAMON). Sadrži rezultate mjerenja radioaktivnosti u površinskom zraku na sedam lokacija: Beograd (Srbija),
Ljubljana i Krško (Slovenija), Sarajevo (Bosna i Hercegovina), Podgorica (Crna
Gora), Skopje i Bitola (Sjeverna Makedonija). Naš rad daje statističku analizu
mjesečnih (prosječnih) vrijednosti koncentracija aktivnosti radionuklida za svaku
lokaciju od 2010. do 2019. Rezultati pokazuju prostorne razlike i vremensku
evoluciju radioaktivnosti zraka u ovoj regiji koja je obično nedovoljno zastupljena

AB  - Measurements of activity concentrations of radionuclides Be-7 (beryllium-7), Pb210 (lead210), and Cs-137 (cesium-137) in the Earth’s atmosphere are essential for
understanding atmospheric processes, air quality, and environmental radioactivity.
Beryllium-7 is a radioactive isotope produced primarily by cosmic ray interactions
with nitrogen and oxygen atoms in the upper atmosphere. Its short half-life makes
it a valuable tracer for atmospheric processes on relatively short timescales. Lead210 is a radioactive isotope whose primary source in the atmosphere is decay
of radon gas. With a longer half-life than Be-7, it is suitable for studying longerterm atmospheric processes. Cesium-137, on the other hand, is an anthropogenic
radioisotope with a half-life even longer than that of Pb-210, which makes it a good
long-term environmental tracer.
The Ground Air Radioactivity Monitoring (GRAMON) database has been recently
established. It contains the outcomes of radioactivity measurements in the surface air at seven locations: Belgrade (Serbia), Ljubljana and Krško (Slovenia),
Sarajevo (Bosnia and Herzegovina), Podgorica (Montenegro), Skopje and Bitola
(North Macedonia). Our paper gives a statistical analysis of monthly (average)
values of the radionuclides’ activity concentrations for each location from 2010
to 2019. The results demonstrate spatial differences and temporal evolution of air
radioactivity over this region commonly underrepresented in large-scale studies.

AB  - Beryllium-7 is a natural radionuclide used as a tracer of the stratospheric-tropospheric exchange. Its abundance in the surface air is expected to change as the temperatures in the atmosphere increase.
To investigate the temporal trends of the beryllium-7 activity concentrations and temperature, we apply spectral analysis to time series from three sampling sites: Belgrade in Serbia, and Ljubljana and Krško in Slovenia. The sites lie close to the 45 ºN parallel, with Krško approximately 400 km and Ljubljana around 500 km west of Belgrade. Between January 1991 and December 2019, the air filter samples were collected using air samplers; a monthly composite sample was formed and analysed by gamma spectrometry. We use monthly mean temperature records from the European Climate Assessment & Dataset, the Republic Hydrometeorological Service of Serbia for Belgrade, and the Slovenian Environment Agency for the sites in Slovenia.
In the spectral analysis decomposition, we look into a term called trend that represents the overall growth (increase or decrease) in the data records. The trend is calculated using a linear fit. All three sites show 1) positive temperature trends, however statistically insignificant (at the 95 % confidence level), and 2) statistically significant beryllium-7 activity concentration trends of 2.26 %/year, 1.13 %/year, and 0.50 %/year in Belgrade, Ljubljana, and Krško, respectively.
The results confirm our initial hypothesis–over the 28 investigated years, the beryllium-7 activity concentrations increase in the surface air. On the other hand, the non-significant temperature rise in our records suggests that within our method, the temporal resolution of one month is insufficient for obtaining a statistically significant temperature trend.
