AB  - U ovom istraživanju analizirana je fraktalna priroda vremenske serije specifične aktivnosti berilijuma-7 u površinskom sloju atmosfere u Beogradu, Srbija, sa ciljem da se prouči dinamika njene samosličnosti, a s posebnim fokusom na godišnji ciklus. Korišćene su metode vejvlet analize i vremenski zavisne detrendovane pokretne srednje vrednosti radi identifikacije karakterističnih intervala i procene Hurstovih eksponenata. Podaci o specifičnoj aktivnosti berilijuma-7 preuzeti su iz GRAMON baze podataka, za lokaciju Beograd (44,88 °N; 20,58 °E; 95 m nadmorske visine). Vremenska serija obuhvata 362 mesečna merenja od 1991. do 2022. godine. Rezultati ukazuju na postojanje izraženog godišnjeg ciklusa u ovoj vremenskoj seriji. Takođe, promene u lokalnom Hurstovom eksponentu otkrivaju varijacije u ponašanju vremenske serije – ona iz umereno korelisanog prelazi u izrazito antikorelisan proces između 2015. i 2020. godine. Ovaj rezultat biće predmet šire analize koja uključuje i druge lokacije iz GRAMON baze podataka.
AB  - This research analyzes the fractal nature of the beryllium-7 specific activity time series in the near-surface layer of the atmosphere in Belgrade, Serbia. The aim was to study the dynamics of self-similarity in this series, with a particular focus on the annual cycle. Wavelet analysis and time-dependent detrended moving averages were used to identify characteristic intervals and estimate Hurst exponents. The data on specific activity of beryllium-7 were obtained from the GRAMON database for the location of Belgrade (44.88 °N; 20.58 °E; 95 m a.s.l.). The time series comprises 362 monthly measurements between February 1991 and December 2022. The results indicate a pronounced annual cycle in this time series. Moreover, changes in the local Hurst exponent reveal variations in the behavior of the time series, transitioning from moderately correlated to highly anti-correlated process between 2015. and 2020. This finding will be a subject of a further analysis including other locations from the GRAMON database.

AB  - U radu je predstavljena novoformirana baza podataka GRAMON (Ground Air Radioactivity Monitoring) koja sadrži rezultate merenja radioaktivnosti u vazduhu na sedam lokacija: Beograd (Srbija), Ljubljana i Krško (Slovenija), Sarajevo (Bosna i Hercegovina), Podgorica (Crna Gora), Skoplje i Bitola (Severna Makedonija). Iz baze su za sve lokacije preuzete mesečne vrednosti specifične aktivnosti prirodnog radionuklida berilijuma-7 i potom analizirani deskriptivni statistički parametri od januara 2010. do decembra 2019. godine. Srednje vrednosti specifične aktivnosti berilijuma-7 tokom ovog perioda kreću se od 3,32 mBq/m3 u Sarajevu do 5,93 mBq/m3 u Beogradu. Koeficijent varijacije najmanji je za Krško (37,7%) i Sarajevo (38,6%), a najveći za Beograd (54,8%) i Bitolu (72,4%). Ipak, 3σ-opsezi svih sedam vremenskih serija se preklapaju. U daljoj statističkoj analizi biće ispitano da li među ovim vremenskim serijama postoje značajne razlike.
AB  - This paper presents a recently established Ground Air Radioactivity Monitoring (GRAMON) database that contains the results of radioactivity measurements in the air at seven locations: Belgrade (Serbia), Ljubljana and Krško (Slovenia), Sarajevo (Bosnia and Herzegovina), Podgorica (Montenegro), Skopje and Bitola (North Macedonia). Monthly values of specific activity of the natural radionuclide beryllium-7 were selected from the database and descriptive statistical parameters were analyzed for each location from January 2010 to December 2019. The mean values of the specific activity of beryllium-7 over this period range from 3.32 mBq/m3 in Sarajevo to 5.93 mBq/m3 in Belgrade. The coefficient of variation is the least for Krško (37.7%) and Sarajevo (38.6%), and the largest for Belgrade (54.8%) and Bitola (72.4%). Still, the 3σ-intervals of all seven time series overlap. Further statistical analysis will investigate whether there are any significant differences among these time series.

In addition, the paper gives radiation hazard parameters, i.e., radium equivalent activity, absorbed dose rate, annual effective dose equivalent, external hazard index, annual gonadal dose equivalent, and excess lifetime cancer risk outdoors that we calculated from the obtained content of the natural radionuclides in the soil samples. We compared the parameters to previously published results for different parts of the country and looked into the radioecological status of the investigated areas.

AB  - Asymptomatic outdoor dogs can be carriers of Babesia canis, but data describing the development of an acute phase response (APR) are not available. We hypothesised that these dogs have a moderate APR that could be detected by hematological and biochemical changes. Two groups of Babesia-exposed dogs were represented by nine B. canis PCR-positive and twenty B. canis PCR-negative, seroreactive dogs. The control group consisted of ten Babesia-naïve dogs. Serum amyloid A (SAA), paraoxonase-1 (PON-1), complete blood count, and biochemistry parameters were analysed by standard methodologies. Protein and lipoprotein fractions were separated using agarose gel electrophoresis (GE), and the dominant diameters of lipoproteins were assessed on gradient GE. Results were evaluated using non-parametric tests and the Receiver Operating Characteristic curve. SAA (median 39.0 μg/mL, range 2.2–48.8 μg/mL), total protein (median 74.7 g/L, range 57.1–98.3 g/L) and the dominant diameter of α-lipoproteins (median 13.31 nm, range 12.09–14.17 nm) in B. canis PCR-positive dogs were higher relative to dogs in the control group or dogs that were PCR-negative but seroreactive (p < 0.001 for both groups). Mild to moderate anemia (4/29), thrombocytopenia (7/29), and leukocyte counts that were close to the upper limit of the reference range were encountered in both Babesia-exposed groups. When compared to controls, Babesia-exposed dogs displayed decreased a PON-1 activity and protein GE pattern consistent with low-grade chronic inflammation (p < 0.001 for both groups). Dogs with detectable amounts of B. canis DNA in blood contain increased levels of SAA and total protein along with α-lipoproteins that display an increased diameter relative to those dogs with positive Babesia serology but undetectable levels of B. canis DNA in blood.

AB  - The aim of the study is the investigation of the activity concentration of 137Cs and 40K in blueberry-based products that are available on the market in the Republic of Serbia. Samples were bought in stores during September 2017 and in total, ten packaged juices, two jams, two sweets and a fresh wild blueberry were measured. The activity concentrations of 137Cs in blueberry-based juices, jams and sweets varied from <MDA to 4.1 Bq/kg, <MDA to 21 Bq/kg and 0.6 Bq/kg to 28 Bq/kg, respectively. The average activity concentration of 137Cs in fresh wild blueberry was 4.1 Bq/kg. In Serbia, the recommended activity concentration of 137Cs in juices and sweets is 15 Bq/kg and 150 Bq/kg in fresh blueberries. The tested samples of juices, jams, fresh wild blueberry and one of the sweets meet the set criteria for 137Cs while one sweets sample exceeds the limit. The activity concentrations of 40K in juices, jams and sweets varied from 3.5 to 55 Bq/kg, 13.9 to 19.2 Bq/kg and 17.2 to 227 Bq/kg, respectively. The average activity concentration of 40K in fresh wild blueberry was 32 Bq/kg. With the obtained result the annual effective dose equivalent due to ingestion of blueberry-based products for adults was calculated, and for 137Cs in blueberry-based juices, jams, sweets and fresh wild blueberry varied from 0.2 to 2.5 Sv, 2.8 Sv, 0.4 to 17.0 Sv and 2.5 Sv, respectively. The annual effective dose equivalent for 40K in blueberry-based juices, jams, sweets and fresh wild blueberry varied from 1.0 to 16.0 Sv, 1.2 Sv, 5.0 to 66.0 Sv, and 9.3 Sv, respectively. © 2019 RAD Association.

AB  - Mineral additives, such as monocalcium phosphate, that are commonly used on pig farms, are obtained by processing phosphate mineral ore, and can contain high levels of 238U. Since ingestion is the main route of radioactive contamination of both animals and humans, the goal of this paper is to measure specific activity of natural and artificial radionuclides in monocalcium phosphate and complete feed mixtures for pigs. Mineral additives with high levels of natural radionuclides can contaminate complete feed mixtures making them unsuitable for use. Samples were collected from three different farms, and in total fifteen samples of monocalcium and forty five samples of complete feed mixture were measured. Samples of monocalcium phosphate show the 238U activity concentration of 13.2-2097Bq/kg. Other naturally occurring radionuclides are measured in monocalcium and the results give: 21.4-25.5 Bq/kg for 40K, 1.5 -12.1 Bq/kg for226Ra, 1.5-2.9 Bq/kg for 232Th, and 1.5-10.8 Bq/kg for 214Bi. These radionuclides are further measured in complete feed mixtures and only one sample shows elevated concentrations of 238U (3.1 Bq/kg) and 226Ra (3.5 Bq/kg). Potassium-40 is detected in all samples, with the specific activity range 208-329 Bq/kg, while other naturally occurring radionuclides and artificial radioceasium are below the detection limits.

AB  - To estimate an influence of amunicipal waste landfill on the environment and food
chain, gamma spectrometric analysis of the various environmental samples is
conducted. The samples were collected in the village of Vinča, Grocka municipality,
Belgrade, Serbia, during 2016, and included the following: soil at a depth of 0–20 cm
and 20–40 cm; water samples from wells and the Danube river; fruit samples of apples,
pears, peaches and apricots; vegetable samples of onions, carrots, potatoes, cabbages
and corn; products of animal origin used in human diet–eggs, goat milk, goat cheese,
pork, pork liver and chicken meat. A content of 40K, 238U, 235U, 226Ra, 214Bi, 232Th, and
137Cs in the samples is investigated. The results show concentrations of the natural
radionuclides within the reported ranges for Serbia. The artificial 137Cs is detected in
the soil (7.1–41.1 Bq/kg), but not in any of the other samples from the food chain.
Therefore, our results imply that the products of plant and animal origin produced in
the vicinity of the landfill are radiologically safe for human consumption.

ishrane. Svi uzorci hrane biljnog i životinjskog porekla su radijaciono higijenski
bezbedni za ljudsku ishranu., To estimate an influence of amunicipal waste landfill on the environment and food
chain, gamma spectrometric analysis of the various environmental samples is
conducted. The samples were collected in the village of Vinča, Grocka municipality,
Belgrade, Serbia, during 2016, and included the following: soil at a depth of 0–20 cm
and 20–40 cm; water samples from wells and the Danube river; fruit samples of apples,
pears, peaches and apricots; vegetable samples of onions, carrots, potatoes, cabbages
and corn; products of animal origin used in human diet–eggs, goat milk, goat cheese,
pork, pork liver and chicken meat. A content of 40K, 238U, 235U, 226Ra, 214Bi, 232Th, and
137Cs in the samples is investigated. The results show concentrations of the natural
radionuclides within the reported ranges for Serbia. The artificial 137Cs is detected in
the soil (7.1–41.1 Bq/kg), but not in any of the other samples from the food chain.
Therefore, our results imply that the products of plant and animal origin produced in
the vicinity of the landfill are radiologically safe for human consumption.",

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.

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.

Srbija, a druga od 29. januara do 3. februara 2017. u skijalištu Val Soni, Francuska.
Izlaganje je mereno ličnim monitorima UV zračenja. U Val Soniju, dva monitora merila
su spoljašnje UV zračenje koje je uzeto kao referentna tačka za izmerena lična
izlaganja. Metodom vejvlet transformacije (VT) izračunate su spektralne funkcije
izmerenih podataka kako bi se ustanovili pojedinačni obrasci ponašanja skijaša i nivo
individualne izloženosti UV zračenju. Rezultati ne pokazuju razliku u srednjem nivou
grupne izloženosti na različitim lokacijama, jer se u oba slučaja dobija srednja vrednost
nagiba VT spektra snage signala približno jednaka jedan. Ova vrednost govori o
visokom stepenu izlaganja sunčevom UV zračenju, koja je kod skijaša najverovatnije
posledica dugotrajnog kontinuiranog boravka na suncu. Obrasci ponašanja skijaša,
međutim, pojedinačno se razlikuju u oba skijališta, što se ogleda u nagibu VT
spektralnih funkcija koji se kreće u rasponu od (0,50±0,02) do (1,44±0,02). U VT
spektralnim funkcijama uočeni su karakteristični maksimumi koji mogu da ukažu na
dužinu ukupnog kontinuiranog pojedinačnog izlaganja UV zračenju kod skijaša. Ovaj
kvantitativni podatak može poslužiti u budućim procenama potrebe za korigovanjem
pojedinačnog ponašanja na suncu.
AB  - Exposure to solar ultraviolet (UV) radiation is analysed for two groups of skiers. One
group measured UV exposure over 1-7 January 2017 in the StaraPlanina ski resort in
Serbia, while the other performed measurements between 29 January and 3 February
2017 in the Val Cenis ski resort in France. Exposure was measured using personal UV
monitors. In Val Cenis, two monitors recorded ambient UV radiation which is taken as
a reference point for the measured personal exposures. To establish personal patterns
of behaviour and a level of individual exposure to solar UV, wavelet transform (WT) is
used to calculate spectral functions of the obtained data. The results show no significant
difference in the mean levels of group exposure at different locations, as the mean slope
of the WT spectra is approximately one in both cases. This value implies a high UV
exposure which most likely results from prolonged periods of time spent in the sun. On
the other hand, the individual slopes of the WT spectral functions range between
(0.50±0.02) and (1.44±0.02), and thusindicate personal differences in behavioural
patterns of the skiers. Further, the WT spectral functions show characteristic peaks that
demonstrate the duration of the total continual individual UV exposure in skiers, and
this result could be used in future assessments and recommendations for modification of
personal behaviour in the sun.

AB  - Tokom 1987–2013. godine vršena su ispitivanja na planinama Kopaonik, Tara, Maljen i
Zlatibor, sa ciljem da se utvrdi sadržaj 137Cs u ovim područjima i njegova migracija kroz
lanac ishrane. Specifična aktivnost 137Cs u zemlji, travi, senu, mleku, mlečnim
proizvodima, mesu i biljnim čajevima određena je standardnom metodom spektrometrije
gama zračenja na poluprovodničkim detektorima. Rezultati pokazuju da je černobiljski
radiocezijum i dalje prisutan u životnoj sredini. U svim karikama lanca ishrane: zemljište
– biljke – proizvodi životinjskog porekla, tokom 2000–2007. godine na Tari i Maljenu,
detektovan je radiocezijum, a najviši stepen kontaminacije nađen je u uzorcima sa
područja Maljena. Međutim, u uzorcima sa Kopaonika koji su prikupljeni 2013. godine,
radiocezijum nije detektovan u mleku, siru niti u mesu. Razlike u nivou kontaminacije
zemljišta na ispitivanim lokacijama posledica su razlika u količini padavina posle
černobiljskog akcidenta, nadmorske visine, karakteristika reljefa, sastava zemljišta i vrste
biljaka. Najviša specifična aktivnost 137Cs u lekovitom bilju sakupljenom tokom
2011–2012. godine u planinskim područjima, izmerena je u vrsti V. myrtillus
AB  - To investigate content of 137Cs and its migration through the food chain in mountainous
regions in Serbia, environmental samples were collected over 1987–2013. Specific
activity of 137Cs in samples of the soil, grass, hay, milk, dairy products, meat and herbal
tea plants was determined by standard gamma spectroscopy on semiconductor detectors.
Samples from the mountains of Kopaonik, Tara, Maljen and Zlatibor were analysed. The
results imply that the Chernobyl radioceasium is still present in the environment.
Radioceasium was detected in all parts of the food chain, from the soil, through plants to
animal products, in Tara and Maljen over 2000–2007. A higher level of contamination
was found in the samples from Maljen. However, 137Cs was not detected in the milk,
cheese and meat samples that were collected from Kopaonik during 2013. Differences in
the soil contamination noted across the investigated locations are a result of a number of
factors, including the amount of precipitation after the Chernobyl nuclear accident,
altitude, type of relief, soil and plants. The highest 137Cs specific activity in herbal tea
plants that were collected over 2011–2012, is measured in V. mirtillus.
