AB  - The procedure of radioactive standards preparation by spiking selected matrices with a certified mixture of radionuclides and its validation is presented in this paper. The uncertainty budget of standard total activity was elaborated in details. The experimentally obtained efficiency curves, as well as comparison with the curves obtained by the efficiency transfer, are presented. Additionally, in order to confirm claimed homogeneity of prepared standard bulk materials, the efficiency versus density dependence for the individual gamma ray energies was checked for the same geometries and the results are presented. The results of the participation in recent IAEA PT scheme are discussed also. © 2021 Elsevier Ltd

AB  - Након измерене високе концентрације радона у три просторије у једној кући  почетком 2018. године, настављено је испитивање концентрације у свим годишњим добима, а број просторија је повећан на пет. Као што је очекивано, концентрација радона је у току летњих месеци била много мања него у зимском периоду, првенствено због сталног проветравања. У осталим годишњим добима уочена је велико повећање коцентрације радона са смањењем спољашње температуре. Такође је уочено смањење концентрације радона у свим просто-ријама наредне зиме, за приближно исти хладни период, када је уместо угља коришћен дрвени пелет.
AB  - The high radon concentrations were measured in three rooms in one house at the beginning of 2018. After that, radon testing was continued during all seasons and the number of rooms was increased to five. As expected, the concentration of radon during the summer was much lower than in the winter period, primarily due to constant natural ventilation. In other seasons, a large increase in radon concentration with a decrease in the  outside  temperature  was  observed.  There  was  also  a  decrease  in  radon concentrations in all rooms in the following winter, in approximately the same cold period, when wood pellets were used instead of coal.

AB  - Thermal and kinetics behaviors of the low-rank coals from different annual periods (Kolubara (2015)/(2018) and TENT A (2015)/(2018)) during combustion process in air atmosphere, using simultaneous TGA-DTG-DTA-MS measurements were investigated. The FTIR spectroscopy was used to gain additional information on coals structures. Kolubara and TENT A coals from (2015)/(2018) annual periods show differences in reactivity, where the reason for this demeanor lies in differences in decomposition kinetics of these coals. The conclusions made on the basis of model-based analysis clearly indicate that differences in combustion reaction pathways (especially in transitions from primary to secondary combustion stages) arise from continual changes in physical structure of the coals. It was found that the mineral matter significantly influences on the reactivity of coal during combustion, where this is particularly pronounced for TENT A coal particles. © 2019 Elsevier B.V.

AB  - The uncertainty of the measurement results is an indicator of the quality of the performed measurement. In the testing laboratories, the combined measurement uncertainty is usually given at the level of confidence of 95% (k = 2). If the laboratory analysis is preceded by a sampling procedure, the uncertainty budget of the measurement results should (according to ISO17025: 2017) include the uncertainty arising from the sampling procedure. This paper describes the procedure for estimating the uncertainty of the results of measurement due to sampling.

AB  - Godine 2018. Laboratorija za zaštitu od zračenja i zaštitu životne sredine je učestvovala u interkomparaciji "REM 2018 radon-in-water proficiency test". Zadatak je bio izmeriti koncentraciju radona u dostavljenom uzorku vode. Ovaj uzorak je meren gama spektrometrijski na HPGe detektoru. Najpre je merenje izvršeno na uzorku u nativnom obliku, bez otvaranja boce u kojoj je dostavljen. Zatim je sadržaj boce prebačen u Marineli geometriju i ponovo izmerenna istomdetektoru.Pri proračunu aktivnosti korišćen je transfer efikasnosti programom EFFTRANi kalibracija QA/QC uzorkom vode,dostavljenim  u  okviru  interkomparacije  IAEA-TEL-2018-03.Poređenjem dobijenih rezultata i referentnevrednosti dateu preliminarnom izveštaju organizatora interkomparacije, utvrđeno je da postoji značajna zavisnost rezultata odpristupa merenju i proračunu aktivnosti. U ovom radu su predstavljeni rezultati oba pristupa i analiza i komentar tačnosti i preciznosti rezultata.
AB  - In 2018, Laboratory for Environment and Radiation Protection took part in the proficiency test "REM 2018 radon-in-water proficiency test". The task of this proficiency test was to determine the concentration of radon in the water sample. This sample  was  measured  by  gamma  spectrometry  on  HPGe  detector.  Firstly,  the measurement was performed on the native sample, without opening the bottle in which the sample was delivered. After that, the sample was placed into Marinelli beaker and measured again on the same detector. To calculate the activity concentration of radon in the  sample,  the  calibration  was  performed  using QA/QC  sample  from  the IAEA-TEL-2018-03 proficiency test andthe efficiency transfer was performed using EFFTRAN software. Comparison of the obtained results with the reference value, provided in the preliminary report of the proficiency test, showed that there is a significant influence of the measurement geometry and the calculation approach. In thispaper, the results of both approaches to the measurement and calculation will be presented and the trueness and precision of the results will be analyzed and commented.

AB  - Beryllium-7 (7Be) is a radioactive beryllium isotope that is produced in the interaction of cosmic radiation with atmospheric atoms. Due to the heterogenous of the Earth's magnetic  field,  the  intensity  of  cosmic  radiation  exhibits  spatial  distribution,  while  the time  distribution  is  a  consequence  of  the  time-varying  magnetic  field  of  the  Sun.  The aim  of thisresearch  is  to  analyzethe  influence  of  the  intensity  of  cosmic  radiation  on the 7Be concentration in samples of the total (dry and wet) deposit. The deposit samples were  collected  at  the  Vinţa  Institute  of  Nuclear  Sciences,  and  all 7Be  concentration measurements  were  performedin  the  Department  of  Radiation  and  Environmental Protection.  The  results  of  the  measurements  were  collected  in  the  period  from  1994  to 2016 and they were correlated with the monthly neutron monitor data of the "Apatity",the Polar Geophysical Institute, the Russian Academy of Sciences. This station has the neutron  monitor  "Standard  18-NM-64"  located  at  the  altitude  of  181  m  with  geogra-phical coordinates of N:  67.57° and E: 33.39°. Also, the results of the measurement of both  observed  parameters  are  grouped  by  years  and  months  of  the  year,  and  then  their annual and monthly indices were determined. After that, the annual as well as monthly indices  of  the  observed  parameters  were  correlated.  The  obtained  results  indicate  that the fluctuations in the galactic part of cosmic radiation affect the variation of the annual 7Be  concentration  index  in  the  deposit.  The  coefficient  of  determining  the  annual indices  of  the  observed  parameters  shows  that  the  modulation  of  cosmic  radiation  can explain  33%  of  the  variation of  the  annual  values of the concentration of 7Be in the deposit.

AB  - Activity concentration of natural radionuclides and 137Cs were studied in leaves of the deciduous trees. In the spring and autumn season, leaves were collected in the area of normal background radiation levels represented by city parks in a multi-year period (2002-2012). Measurements by means of gamma-ray spectrometry showed 226Ra and 210Pb seasonal accumulation in leaves, while 238U and 235U could be detected only in autumn. Difference between seasons was not found significant for 40K and 137Cs. The study of radionuclides transfer factors was conducted by analyzing its relationships with basic soil properties at the beginning and the end of the vegetation period. © 2019, Editura Academiei Romane.

AB  - Traces of particulate radioactive iodine (I-131) were detected in the European atmosphere in January/February 2017. Concentrations of this nuclear fission product were very low, ranging 0.1 to 10 mu Bq m(-3) except at one location in western Russia where they reached up to several mBq m(-3). Detections have been reported continuously over an 8-week period by about 30 monitoring stations. We examine possible emission source apportionments and rank them considering their expected contribution in terms of orders of magnitude from typical routine releases: radiopharmaceutical production units > sewage sludge incinerators > nuclear power plants > spontaneous fission of uranium in soil. Inverse modeling simulations indicate that the widespread detections of I-131 resulted from the combination of multiple source releases. Among them, those from radiopharmaceutical production units remain the most likely. One of them is located in Western Russia and its estimated source term complies with authorized limits. Other existing sources related to I-131 use (medical purposes or sewage sludge incineration) can explain detections on a rather local scale. As an enhancing factor, the prevailing wintertime meteorological situations marked by strong temperature inversions led to poor dispersion conditions that resulted in higher concentrations exceeding usual detection limits in use within the informal Ring of Five (Ro5) monitoring network.

AB  - One of the main problems in quantitative gamma-ray spectroscopy is the determination of detection efficiency, for different energies, source-detector geometries, and composition of samples or sources. There are, in principle, three approaches to this issue: experimental, numerical, and semiempirical. Semiempirical approach is based on the calculation of the efficiency for the measured sample on the basis of an experimental efficiency measured on the same detector, but with a calibration source that can be of different size, geometry, density, or composition—the so-called efficiency transfer. The aim of this paper is to analyze the semiempirical approach, using EFFTRAN and MEFFTRAN software as a typical example. These software were used in the Department of Radiation and Environmental Protection, Vinča Institute of Nuclear Sciences, on three HPGe detectors. The results were compared to the experimentally obtained efficiency, and further validation is performed by measuring reference materials issued within the framework of several interlaboratory intercomparisons. The analysis of the results showed that the efficiency transfer produces good results with the discrepancies within the limits of the measurement uncertainty. Also, for intercomparison measurement, u test criterion for the trueness of the result was applied showing that the majority of the obtained results were acceptable. Some difficulties were identified, and the ways to overcome them were discussed.

AB  - Specifična aktivnost prirodnih radionuklida 238U, 235U, 226Ra, 210Pb, 232Th i 40K i
proizvedenog 137Cs je merena u uzorcima lišća dve vrste listopadnog drveća, kestena
(Aesculus hippocastanum) i lipe (Tilia spp) koji potiču iz tri gradska parka na užem
području Beograda. Uzorci su sakupljani u vreme prolećne (n=7), letnje (n=2) i jesenje
(n=8) sezone u periodu od 2002-2012. godine. Iz svake pojedinačne sezone uzorci lišća
su spojeni po vrstama pri čemu je dobijen jedan integralni (sezonski) uzorak za svaki
ispitivani park čime je postignuta veća efikasnost detekcije niskog nivoa gama zračenja.
Za određivanje aktivnosti primenjen je metod spektrometrije gama emitera. U svim
pojedinačnim uzorcima suve materije lišća detekcija radionuklida 210Pb i 40K je bila
moguća i njihova specifična aktivnost se nalazila intervalu 15-52 Bq/kg i 310-650
Bq/kg, respektivno. Iako je aktivnost 226Ra bila veoma niska, u intervalu 0,5-5,6 Bq/kg,
ovaj radionuklid je bio izmeren u svim uzorcima (osim u dva) i svim sezonama.
Aktivnost 210Pb i 226Ra se povećavala tokom godine, pri čemu su njihove najveće
vrednosti izmerene u lišću kestena u letnjoj sezoni. Suprotno, aktivnost 40K u lišću lipe i
kestena je opadala tokom godine. Za razliku od prethodno navedenih, radionuklidi 238U,
235U i 232Th su retko detektovani samo u letnjem i/ili jesenjem periodu i po četiri uzorka
lišća su sadržali 238U (2,7-11,7 Bq/kg) i 235U (0,13-1,0 Bq/kg), a tri 232Th (1,8-3,3
Bq/kg). Proizvedeni radionuklid 137Cs detektovan je u svim uzorcima lišća (osim u dva),
a bez jasnog trenda ponašanja po sezonama i nalazio se u intervalu 0,3-1,2 Bq/kg. Cilj
rada bio je ispitivanje akumulacije prirodnih radionuklida i njihovog potencijalnog
variranja tokom godine u lišću listopadnog drveća.
AB  - The specific activity of naturally occurring radionuclides 238U, 235U, 226Ra, 210Pb, 232Th,
and 40K and fallout 137Cs was measured in the samples of leaves of two deciduous tree
species, chestnut (Aesculus hippocastanum) and linden (Tilia spp.) common for the
Belgrade urban area. Samples were collected in the spring (n = 7), summer (n = 2) and
autumn (n = 8) during the vegetation period from 2002 to 2012. From each season,
samples of leaves were combined according to two species and one single integral
(seasonal) sample was obtained in order to improve detection efficiency of low gamma
radiation level. Specific activities were determined using the gamma-ray spectrometry
method. 210Pb and 40K radionuclides were detected in all the samples of leaves and their
specific activity was in the range (Bq/kg dry weight): 15 - 52 and 310 - 650,
respectively. Although the 226Ra level was very low and in the range from 0.5 - 5.6
Bq/kg, this radionuclide has been measured in all samples (except in the two) and each
season.
210Pb and 226Ra activity increased during the vegetation period and their
highest values were found in the leaves of chestnut trees in the summer season. In
contrast, the activity of 40K in the leaves of linden and chestnut has decreased.
Detection 238U, 235U and 232Th radionuclides was scarce and only in the summer and/or
autumn. Four samples of leaves contained 238U (2.7 - 11.7 Bq/kg dry wt) and 235U (0,13
- 1.0 Bq/kg dry wt) and three of them 232Th (1.8 - 3.3 Bq/kg dry wt). Man-made
radionuclide 137Cs (0.3-1.2 Bq/kg dry wt) was detected in all samples of leaves (except
in two) and no clear trend according to seasons was found. The aim was to investigate
the accumulation of naturally occurring radionuclides and fallout 137Cs in the leaves of
deciduous trees and their potential variations during the vegetation period.

Za određivanje aktivnosti primenjen je metod spektrometrije gama emitera. U svim
pojedinačnim uzorcima suve materije lišća detekcija radionuklida 210Pb i 40K je bila
moguća i njihova specifična aktivnost se nalazila intervalu 15-52 Bq/kg i 310-650
Bq/kg, respektivno. Iako je aktivnost 226Ra bila veoma niska, u intervalu 0,5-5,6 Bq/kg,
ovaj radionuklid je bio izmeren u svim uzorcima (osim u dva) i svim sezonama.
Aktivnost 210Pb i 226Ra se povećavala tokom godine, pri čemu su njihove najveće
vrednosti izmerene u lišću kestena u letnjoj sezoni. Suprotno, aktivnost 40K u lišću lipe i
kestena je opadala tokom godine. Za razliku od prethodno navedenih, radionuklidi 238U,
235U i 232Th su retko detektovani samo u letnjem i/ili jesenjem periodu i po četiri uzorka
lišća su sadržali 238U (2,7-11,7 Bq/kg) i 235U (0,13-1,0 Bq/kg), a tri 232Th (1,8-3,3
Bq/kg). Proizvedeni radionuklid 137Cs detektovan je u svim uzorcima lišća (osim u dva),
a bez jasnog trenda ponašanja po sezonama i nalazio se u intervalu 0,3-1,2 Bq/kg. Cilj
rada bio je ispitivanje akumulacije prirodnih radionuklida i njihovog potencijalnog
variranja tokom godine u lišću listopadnog drveća., The specific activity of naturally occurring radionuclides 238U, 235U, 226Ra, 210Pb, 232Th,
and 40K and fallout 137Cs was measured in the samples of leaves of two deciduous tree
species, chestnut (Aesculus hippocastanum) and linden (Tilia spp.) common for the
Belgrade urban area. Samples were collected in the spring (n = 7), summer (n = 2) and
autumn (n = 8) during the vegetation period from 2002 to 2012. From each season,
samples of leaves were combined according to two species and one single integral
(seasonal) sample was obtained in order to improve detection efficiency of low gamma
radiation level. Specific activities were determined using the gamma-ray spectrometry
method. 210Pb and 40K radionuclides were detected in all the samples of leaves and their
specific activity was in the range (Bq/kg dry weight): 15 - 52 and 310 - 650,
respectively. Although the 226Ra level was very low and in the range from 0.5 - 5.6
Bq/kg, this radionuclide has been measured in all samples (except in the two) and each
season.
210Pb and 226Ra activity increased during the vegetation period and their
highest values were found in the leaves of chestnut trees in the summer season. In
contrast, the activity of 40K in the leaves of linden and chestnut has decreased.
Detection 238U, 235U and 232Th radionuclides was scarce and only in the summer and/or
autumn. Four samples of leaves contained 238U (2.7 - 11.7 Bq/kg dry wt) and 235U (0,13
- 1.0 Bq/kg dry wt) and three of them 232Th (1.8 - 3.3 Bq/kg dry wt). Man-made
radionuclide 137Cs (0.3-1.2 Bq/kg dry wt) was detected in all samples of leaves (except
in two) and no clear trend according to seasons was found. The aim was to investigate
the accumulation of naturally occurring radionuclides and fallout 137Cs in the leaves of
deciduous trees and their potential variations during the vegetation period.",

AB  - Soil represents a potential source of contamination of biota. Hence, tracking
distribution of radioactivity in the soil is very important, particularly in cultivated soil
used for intensive agricultural production, where it gives an insight into the cumulative
deposition and dispersion of radioactivity in that part of agroecosystems. To determine
the radioactivity of cultivated soil of southeast Belgrade, specific activities of natural
radionuclides 210Pb, 238U, 235U, 226Ra, 232Th and 40K were measured using high
resolution gamma spectrometry. This paper gives the vertical distribution of the
investigated radionuclides in the soil and a correlation of their specific activities with
the physico-chemical characteristics of the soil. The measured specific activities are
41-74 Bq kg-1 for 210Pb, 39-67 Bq kg-1 for 238U, 2,4-3,6 Bq kg-1 for 235U, 37-53 Bq kg-1
for 226Ra, 51-60 Bq kg-1 for 232Th and 540-670 Bq kg-1 for 40K. Pierson’s linear
correlation coefficients imply an association between the specific activities of 235U,
238U, 232Th and 40K and the physical and chemical soil characteristics in the
investigated area. The distribution of these radionuclides depends mostly on the content
of fine fraction - clay, but also on the content of humus, CaCO3 and organic carbon in

226Ra and physico-chemical characteristics of the investigated soil samples.

Be (477,6 keV) and 210Pb (46 keV) concentration in
air samples, conducted in Radiation and Environment Protection Laboratory, Institute
"Vinča", in the period from year 1994. up to date. The first efficiency estimate was
performed using a set of point sources (Coffret d’etalon ECGS-2, Sacle, Franse), then a
planchette, filled with aerosol dust obtained for the Proficiency test conducted within
the framework of SEV project, while since year 2008. the laboratory reference
materials are in use - the aerosol dust matrix placed in the vial, prepared by spiking
with the certified radioactive solution. By comparing the values for 7
Be and 210Pb
concentrations obtained using each of the mentioned calibration methods, the influence
of the calibration method on the measurement results was shown.

Workshop on Determination of Low Activity Radio-Caesium in Freshwater, kao deo
projekta RER/7/008 - Strengthening Capabilities for Radionuclide Measurement in
the Environment and Enhancing Quality Assurance/Quality Control System for
Environmental Monitoring. Ukupno 31 laboratorija iz 29 zemalja Evrope i Japana,
uzela je učešća u ovoj radionici. Pre početka radionice, laboratorije učesnice su dobile
uzorke površinske vode iz Japana i Dunava, kao i QA/QC uzorak vode poznate
aktivnosti, za interkomparaciju. Zadatak je bio određivanje veoma niske koncentracije
134Cs i 137Cs u ovim uzorcima, uz korišćenje različitih metoda pripreme – prekoncentracije uzoraka. Laboratorije učesnice su u pripremi koristile uparavanje do suvog
ostatka ili definisane zapremine, hemijsko obogaćivanje ili jon – izmenjivačke metode,
sa ciljem da se concentriše sadržaja radiocezijuma u uzorcima. Iako su ispitivani radionuklidi bili prisutni u koncentracijama reda veličine 10-2 Bq/kg, rezultati laboratorija
učesnica su bili u velikoj većini prihvaćeni. Ipak, identifikovani su neki problem vezani

AB  - Workshop named Data Evaluation Workshop on Determination of Low Activity
Radio-Caesium in Freshwater was held in February 2017 in Vienna, as a part of
project RER/7/008 - Strengthening Capabilities for Radionuclide Measurement in the
Environment and Enhancing Quality Assurance/Quality Control System for
Environmental Monitoring. Total of 31 participating laboratories from 29 European
countries and Japan took part in this workshop. Prior to the workshop, the participating
laboratories received samples of fresh water from Japanese rivers and Danube, as well
as the QA/QC sample of known activity. The task was to determine very low
concentrations of 134Cs and 137Cs in these samples using some method of sample
preparation - preconcentration. The laboratories used total evaporation, evaporation to
a finite volume, chemical enrichment and ion exchange methods in order to concentrate
the radiocaesium in the samples. Despite the very low concentration of analytes in the
samples (order of magnitude 10-2 Bq/kg), the results of participating laboratories were
for the most part acceptable. However, some difficulties regarding chemical yield in
chemical enrichment procedures and loss of the sample during evaporation were
identified.
The aim of this paper is to represent the overall results of the said intercomparison and
to analyze the influence of the preparation method on the obtained results.

AB  - Ugljeni kanisteri se često koriste kao pasivni detektori za određivanje koncentracije
222Rn. Merenja pomoću ugljenih kanistera najčešće traju 2-3 dana, što omogućava brzo
dobijanje rezultata, ali je metoda osetljiva na različite uticaje, kao što su visoka
vlažnost vazduha, ekstremne temperature, promena koncentracije radona itd. Upravo
zbog toga je od velikog značaja poređenje u realnim uslovima ove metode sa drugim
metodama, kao što je merenje pomoću trag detektora. Međutim, veoma različita
vremena merenja otežavaju ovakvu proceduru.
U Institutu za nuklearne nauke „Vinča“ su četiri trag detektora bila postavljena u
periodu od 7, odnosno 13 meseci. U istom periodu su kontinuirano menjani ugljeni
kanisteri, najčešće dvaput nedeljno. Ovi rezultati su omogućili da se izvrši poređenje
metoda, pri čemu su za proračun rezultata za metodu pomoću ugljenih filtera korišćene
kalibracione krive i za statičnu atmosferu i za aktivnu atmosferu. Poređenje je pokazalo
da ne postoji statistički značajna razlika između metoda bilo koje kalibracione krive da
se koriste, s tim što se bolje poklapanje dobija korišćenjem krivih za aktivnu atmosferu.
AB  - Charcoal canisters are often used as passive detectors for determination of
concentration of222Rn. Measurements with charcoal canisters often last 2-3 days, which
provides a fast result, but the method is sensitive to many influences, such as high air
humidity, extreme temperatures, change of radon concentration etc. This is why the
comparison of this method with other methods in realistic conditions is of great
importance. However, different measurement times make this comparison complicated.
Four track etch detectors were deployed in Vinca Institute of Nuclear Sciences for 7
and 13 months. In the same period, charcoal canisters were continuously changed,
usually two times each week. These results allowed comparing the two methods, while
the results for charcoal canisters were obtained by using calibration curves for both
static and active atmosphere. The comparison showed that there is no statistically
significant difference no matter which curves are used. The differences are smaller if
the curves for active atmosphere are used.

the results for charcoal canisters were obtained by using calibration curves for both
static and active atmosphere. The comparison showed that there is no statistically
significant difference no matter which curves are used. The differences are smaller if
the curves for active atmosphere are used.",

AB  - Međusobna povezanost specifičnih aktivnosti berilijuma-7 i olova-210 u prizemnom
sloju atmosfere sa meteorološkim parametrima razmotrena je u faktorskoj analizi.
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
atmosfere nalaze pod različitim dominantnim uticajima. Koncentracija berilijuma-7 je
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
meteorološka parametra, međutim, prestaje da važi sa povećanjem broja faktora u
analizi na tri, kada se izdvaja specifičan faktor koji objašnjava preko 80% varijanse
specifične aktivnosti olova-210.
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.
