AB  - This review paper discusses the content of natural ( 40K, 238U, 226Ra, and 232Th) and artificial (137Cs) radionuclides in the soil of the mountains of Maljen, Tara and Kopaonik in the Republic of Serbia over 2002-2015. 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.

Uzorci zemljišta prikupljeni su u periodu od 2002. do 2015. godine na različitim nadmorskim visinama. Na osnovu sadržaja radionuklida u zemljištu odredili smo parametre radijacionog rizika: radijum ekvivalentnu aktivnost, jačinu doze, godišnju efektivnu dozu spoljašnjeg zračenja, indeks spoljašnjeg hazarda, godišnju gonadnu dozu i faktor rizika pojave kancera na području planinskih regiona Republike Srbije, i potom ih uporedili sa ranije objavljenim rezultatima za pojedine regione Republike Srbije.

AB  - Designated as the most harmful for health, PM2.5 aerosol fraction was a subject of our study. It was collected for all four seasons during 2014/15 in the suburban area of Belgrade (Serbia) and analysed for Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, As, Ba and Pb elements and for NH4+, NO3− and SO42− ions by particle-induced X-ray emission and ion chromatography techniques, respectively. Obtained concentrations have been treated by a combination of several receptor-oriented models to reveal source contributions to the suburban PM2.5 at different spatial scales. Applied positive matrix factorization analysis indicated five main groups of emission sources: biomass burning (14.5%), traffic (3.9%), regional combustion/secondary sulphates (28.8%), local combustion/secondary nitrates (29.7%) and soil (5.4%). Local heating units had been pointed out as dominant contributors by long-range transport and ground-wind circulation analyses. Air masses circulating over the Balkan Peninsula denoted regional emissions as responsible for the high concentrations of secondary sulphates. Local and long-range transport analyses combined suggested that the BB and the LC/NO3 originated from the wider urban area. Several Saharan dust episodes were detected as well. Presented results might be a basis for the development of air pollution mitigation strategies in the continental Balkan area, considered one of the most polluted and under-investigated European regions.

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  - Intensive use of pesticides requires innovative approaches for their removal from the environment. Here we report the method for degradation of dimethoate in water using non-thermal plasma needle and analyze kinetics of dimethoate removal and possible degradation pathways. The effects of dimethoate initial concentration, plasma treatment time, Argon flow rate and the presence of radical promoters on the effectiveness of proposed method are evaluated. With argon flow rate of 0.5 slm (standard litres per minute) 1 × 10−4 M dimethoate can be removed within 30 min of treatment. Using UPLC analysis it was confirmed that one of the decomposition products is dimethoate oxo-analogue omethoate, which is in fact more toxic than dimethoate. However, the overall toxicity of contaminated water was reduced upon the treatment. The addition of H2O2 as a free radical promoter enhances dimethoate removal, while K2S2O8 results with selective conversion to omethoate. Using mass spectrometry in combination with the theoretical calculations, possible degradation pathways were proposed. The feasibility of the proposed method for dimethoate degradation in real water samples is confirmed. The proposed method is demonstrated as a highly effective approach for dimethoate removal without significant accumulation of undesirable toxic products and secondary waste. © 2019 Elsevier Ltd

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  - The subject of this study was a mid-term evaluation of cardiovascular, respiratory and total non-accidental mortalities attributed to exposure to PM 10 , O 3 , NO 2 and SO 2 in the cities of Belgrade, Novi Sad and Nis, representing about 25% of the population of Serbia. The analysis was performed using AirQ+ modelling, by linking annual baseline mortality rates and daily pollutant exposure levels in 2011–2015 based on the cause-specific concentration–response functions. Estimated shares of annual mortality attributed to these pollutants, thanks to harmonizing of assessment methodologies, may stand next to and be compared with results obtained in previously conducted studies. The obtained premature deaths estimated within 95% confidence interval (in parentheses) and attributed to PM 10 , O 3 , NO 2 and SO 2 exposure were 2013 (1344–2677), 1411 (685–2086), 831 (555–1107) and 443 (333–530), respectively. Total non-accidental mortalities due to O 3 and NO 2 exposure were in the range of findings for other regions, while mortalities attributed to PM 10 were higher. It was also found that cardiovascular mortality caused by these four pollutants was higher than respiratory mortality. Based on our results, efficient implementation of abatement strategies that would reduce PM 10 , O 3 and SO 2 concentrations to daily air quality limit values set by the World Health Organization could respectively prevent, in the three cities together, about 233 (156–310), 40 (19–59) and 71 (53–85) premature deaths per year. © 2019, Islamic Azad University (IAU).

The obtained premature deaths estimated within 95% confidence interval (in parentheses) and attributed to PM 10 , O 3 , NO 2 and SO 2 exposure were 2013 (1344–2677), 1411 (685–2086), 831 (555–1107) and 443 (333–530), respectively. Total non-accidental mortalities due to O 3 and NO 2 exposure were in the range of findings for other regions, while mortalities attributed to PM 10 were higher. It was also found that cardiovascular mortality caused by these four pollutants was higher than respiratory mortality. Based on our results, efficient implementation of abatement strategies that would reduce PM 10 , O 3 and SO 2 concentrations to daily air quality limit values set by the World Health Organization could respectively prevent, in the three cities together, about 233 (156–310), 40 (19–59) and 71 (53–85) premature deaths per year. © 2019, Islamic Azad University (IAU).",

AB  - This study of environmental radioactivity was carried out in the soils of an urban area. Naturally occurring gamma-emitting radionuclides and man-made137Cs were found in the soil profiles collected from four parks in the central Belgrade city area and the soil layer was examined every 10 cm and to a depth of 50 cm. Radioisotope activity concentrations (Bq kg−1) in the samples of urban soil using the gamma-ray spectrometry method were in the range of 14–46 for238U, 33–50 for226Ra, 29–63 for210Pb, 1.2–3.4 for235U, 28–50 for232Th, 424–576 for40K and 0.7–35.8 for137Cs. Some of the basic physicochemical soil properties (pH, organic matter content, calcium-carbonate content, particle size distribution) were determined to investigate the impact on the vertical distribution of radionuclides. The results of this investigation showed that variations of activity concentration ratios of radionuclides that belong to the same (238U/226Ra) or different radioactive series (232Th/226Ra;235U/238U), including210Pb/137Cs ratios could well be explained by the properties of the soil. Alkaline pH reaction, the accumulation of organic matter in the uppermost and of carbonates in the deepest layers of urban soil had an effect on238U/226Ra, and210Pb/137Cs activity concentration ratio values, while232Th/226Ra and partially235U/238U ratios were associated with the particle sizes vertical distribution. A study of radionuclides in the samples of leaves of two deciduous tree species common for these parks was also conducted and210Pb and40K were found concentrated in leaves rather than other investigated radionuclides.

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.

detector in order to establish the spatial distribution of radionuclides. Special attention
was paid to 7Be. It is obtained that the distribution of atmospheric deposition of 7Be is

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.

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.

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.

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  - Izlaganje sunčevom ultravioletnom (UV) zračenju analizirano je za dve grupe skijaša:
jedna grupa merila je izlaganje tokom 1-7. januara 2017. na skijalištu Stara Planina,
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

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.

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

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.

AB  - Usled padavina koje su usledile nakon Černobilskog akcidenta 1986. godine, proizvedeni
radionuklid 137Cs je deponovan u zemljištu. S obzirom na njegovo dovoljno dugo vreme
poluraspada (30,05 godina), posebno je važna radiološka zaštita kultivisanog (obradivog)
zemljišta jer se postavlja pitanje da li se ovaj radionuklid zadržava u površinskim
slojevima zemljišta, da li biva usvojen od strane biljaka ili se spušta u dublje slojeve
zemljišta. U ovom radu prikazani su rezultati merenja specifične aktivnosti 137Cs metodom
gama-spektrometrije u zemljištu 15 godina starog voćnjaka pod zasadom breskvi.
Priprema zemljišta za sadnju bresaka izvršena je rigolovanjem, posle čega je usledila 12
godina duga nega voćnjaka, a zatim uzorkovanje zemljišta je izvršeno tri godine nakon
prestanka svih poljoprivrednih tretmana. U radu je prikazan pregled rezultata analize
uticaja dugogodišnje kultivacije (obrađivanja) zemljišta na preraspodelu 137Cs duž profila
dubine 0-80 cm. Linearna i višestruka regresiona analiza primenjene su da bi se procenilo
u kojoj meri su nivoi radioizotopa cezijuma povezani sa: nivoima izotopa kalijuma 40K
detektovanim u zemljištu; zatim, osnovnim osobinama koje karakterišu zemljište (pH,
sadržaj humusa, sadržaj karbonata, granulometrijski sastav, sadržaj higroskopske vlage);
mineralnim sastavom glinovite frakcije zemljišta i dostupnim sadržajima mikroelemenata
(Zn, Cu, Mn, Fe). Obrasci distribucije 137Cs sa dubinom ukazivali su da je cezijum bio
mehanički prenesen iz površinskih ka nižim slojevima zemljišta tokom kultivacije.
Rezultati analiza su pokazali da na zatečenu distribuciju izotopa cezijuma sa dubinom
glavni uticaj imaju varijacije sadržaja humusa i minerala glinovite frakcije zemljišta,
vermikulita, ilita i smektita.
AB  - Due to the fallout followed by Chernobyl accident in 1986 anthropogenic
radionuclide 137Cs was deposited in the soil. Given long half-life of 137Cs (30.05
years), cultivated soils in particular are subject of radiological protection because
the question is whether this radionuclide would be retained in the surface layers of
the soil, adopted by plants or transferred to the deeper soil layers. This paper
presents an overview of the results of 137Cs specific activity measurements by
gamma-spectrometry method in cultivated anthrosol soil of a 15-year old peach
tree plantation at the experimental field “Radmilovac”. Preparing the land for
planting peach trees deep ploughing was conducted followed by 12-year-long
cultivation, and soil sampling was carried out three years after the termination of all
agricultural treatments. Overview of the analyzes of the long-term cultivation
impact on 137Cs redistribution in the soil along the 0-80 cm profile depth is
presented. Linear and multiple regression analysis was applied to assess to what
extent the levels of cesium radioisotopes are associated with a) levels of potassium
isotope 40K detected in the soil; b) the basic features that characterize the soil (pH,
humus content, carbonate content, grain size distribution, moisture content of
hygroscopic); c) mineral composition of the clay fraction of soil and d) available
DTPA-extracted microelements Zn, Cu, Mn and Fe. Patterns of 137Cs distribution
with depth indicated that radiocesium was mechanically transferred from the
surface to the lower layers of soil during the cultivation. The results of the
statistical analysis showed that on radiocesium variations with depth a major
impact had the contents of humus and the main minerals of the clay fraction of soil
– vermiculite, illite, and smectite.

abstract = "Usled padavina koje su usledile nakon Černobilskog akcidenta 1986. godine, proizvedeni
radionuklid 137Cs je deponovan u zemljištu. S obzirom na njegovo dovoljno dugo vreme
poluraspada (30,05 godina), posebno je važna radiološka zaštita kultivisanog (obradivog)
zemljišta jer se postavlja pitanje da li se ovaj radionuklid zadržava u površinskim
slojevima zemljišta, da li biva usvojen od strane biljaka ili se spušta u dublje slojeve
zemljišta. U ovom radu prikazani su rezultati merenja specifične aktivnosti 137Cs metodom
gama-spektrometrije u zemljištu 15 godina starog voćnjaka pod zasadom breskvi.
Priprema zemljišta za sadnju bresaka izvršena je rigolovanjem, posle čega je usledila 12
godina duga nega voćnjaka, a zatim uzorkovanje zemljišta je izvršeno tri godine nakon
prestanka svih poljoprivrednih tretmana. U radu je prikazan pregled rezultata analize
uticaja dugogodišnje kultivacije (obrađivanja) zemljišta na preraspodelu 137Cs duž profila
dubine 0-80 cm. Linearna i višestruka regresiona analiza primenjene su da bi se procenilo
u kojoj meri su nivoi radioizotopa cezijuma povezani sa: nivoima izotopa kalijuma 40K
detektovanim u zemljištu; zatim, osnovnim osobinama koje karakterišu zemljište (pH,
sadržaj humusa, sadržaj karbonata, granulometrijski sastav, sadržaj higroskopske vlage);
mineralnim sastavom glinovite frakcije zemljišta i dostupnim sadržajima mikroelemenata
(Zn, Cu, Mn, Fe). Obrasci distribucije 137Cs sa dubinom ukazivali su da je cezijum bio
mehanički prenesen iz površinskih ka nižim slojevima zemljišta tokom kultivacije.
Rezultati analiza su pokazali da na zatečenu distribuciju izotopa cezijuma sa dubinom
glavni uticaj imaju varijacije sadržaja humusa i minerala glinovite frakcije zemljišta,
vermikulita, ilita i smektita., Due to the fallout followed by Chernobyl accident in 1986 anthropogenic
radionuclide 137Cs was deposited in the soil. Given long half-life of 137Cs (30.05
years), cultivated soils in particular are subject of radiological protection because
the question is whether this radionuclide would be retained in the surface layers of
the soil, adopted by plants or transferred to the deeper soil layers. This paper
presents an overview of the results of 137Cs specific activity measurements by
gamma-spectrometry method in cultivated anthrosol soil of a 15-year old peach
tree plantation at the experimental field “Radmilovac”. Preparing the land for
planting peach trees deep ploughing was conducted followed by 12-year-long
cultivation, and soil sampling was carried out three years after the termination of all
agricultural treatments. Overview of the analyzes of the long-term cultivation
impact on 137Cs redistribution in the soil along the 0-80 cm profile depth is
presented. Linear and multiple regression analysis was applied to assess to what
extent the levels of cesium radioisotopes are associated with a) levels of potassium
isotope 40K detected in the soil; b) the basic features that characterize the soil (pH,
humus content, carbonate content, grain size distribution, moisture content of
hygroscopic); c) mineral composition of the clay fraction of soil and d) available
DTPA-extracted microelements Zn, Cu, Mn and Fe. Patterns of 137Cs distribution
with depth indicated that radiocesium was mechanically transferred from the
surface to the lower layers of soil during the cultivation. The results of the
statistical analysis showed that on radiocesium variations with depth a major
impact had the contents of humus and the main minerals of the clay fraction of soil
– vermiculite, illite, and smectite.",

AB  - The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent from the production of tetramethylthiuram monosulfide (TMTS), and alkyl amine, are presented in this work., Thioureas synthesis was developed in two ways: Method I-reaction of the thiocyanate and alkylamine in the presence of hydrochloric acid; Method II-reaction of the thiocyanate with benzoyl chloride following by amine addition in the first step, and base hydrolysis in the second step. The structure of the synthesized compounds was confirmed by IR, H-1- and C-13-NMR and MS instrumental methods, and purity was determined by high-performance liquid chromatography method. It is shown that the proposed methods offer a high degree of conversion and purity of product, absence of by-products and technological applicability at industrial scale. Considering the importance of the tetramethylthiuram disulfide (TMTD) and TMTS as vulcanization accelerators as well as thiourea as the pharmacologically active compounds, it can be said that application of the optimized methods of thiourea synthesis will provide significant improvement in sustainable development and implementation of eco-friendly production technology.

AB  - Dependence of the lead-210 activity concentration in surface air on meteorological variables and teleconnection indices is investigated using multivariate analysis, which gives the Boosted Decision Trees method as the most suitable for variable analysis. A mapped functional behaviour of the lead-210 activity concentration is further obtained, and used to test predictability of lead-210 in surface air. The results show an agreement between the predicted and measured values. The temporal evolution of the measured activities is satisfactorily matched by the prediction. The largest qualitative differences are obtained for winter months.

AB  - Leaves of linden (Tilia tomentosa L. and Tilia cordata Mill.) and horse chestnut (Aesculus hippocastanum L.) were analysed as biomonitors of radionuclides in urban air. Samples of soils, leaves and aerosols were collected in Belgrade, Serbia. Activities of Cs-137, K-40, Pb-210 and Be-7 in the samples were measured on an HPGe detector by standard gamma spectrometry. Soil-to-leaves transfer factors were calculated. Students t test and linear Pearson correlation coefficients were used for statistical analysis. Differences in local conditions at the sampling sites were not significant, and the mechanisms of the radionuclides accumulation in both plant species are similar. Ceasium-137 was detected in some of the leaf samples only. Transfer factors for Cs-137 and K-40 were (0.03-0.08) and 1.3, respectively. The concentrations of Pb-210 and Be-7 in leaves were higher in autumn than in spring, and there were some similarities in their seasonal patterns in leaves and in air. Weak to medium correlation was obtained for the Pb-210 and Be-7 activities in leaves and aerosols. Large positive correlation was obtained for the Pb-210 activities in linden leaves and the mean activity in aerosols for the preceding months. Different primary modes of radionuclides accumulation in leaves were observed. Since large positive correlation was obtained for the Pb-210 activity in linden leaves and the mean in aerosols for the preceding months, mature linden leaves could be used as biomonitors of recent Pb-210 activity in air.

AB  - Activities of Be-7 and Pb-210 were monitored in surface air in Belgrade, Serbia, from 2004 to 2012. The measurements were taken from two locations, in an open field of a city suburb and in the central city area. The activities were determined on HPGe detectors by standard gamma spectrometry. The Be-7 activity shows a pronounced seasonal pattern, with the maximum in spring-summer and minimum in winter, while the Pb-210 activity exhibits two maxima, in autumn and late winter. The mean monthly concentrations measured at both sites are below 9 mBq/m(3) and 1.3 mBq/m(3) for Be-7 and Pb-210, respectively. The obtained correlation of the Be-7 activity with the number of sun-spots is not statistically significant. Relations of the radionuclides activities with climate variables (precipitation, temperature, relative humidity, cloud cover, sunshine hours, and atmospheric pressure) are also investigated, but the only significant correlations are found for the Be-7 activity with temperature and sunshine hours, and the Pb-210 activity with atmospheric pressure. The maximum Be-7 and Pb-210 activities corresponding to binned total monthly precipitation data imply different modes of the radionuclide scavenging from the atmosphere. During dry periods, accumulation of the radionuclides in the atmosphere leads to their increased activities, but no correlation was found between the activities and the number of consecutive dry days.

AB  - Purpose: This study was undertaken to explore the effects of the jaws and the MLC openings on the neutron dose equivalent (DE) at the maze door and neutron flux at the patient plane. Methods: The neutron dose equivalent was measured at the maze entrance door of a 15 MV therapy linear accelerator room. All measurements were performed using various field sizes up to 40 cm x 40 cm. Activation detectors constructed from natural Indium (In) were exposed at Cd envelope to neutrons in order to estimate relative changes of epithermal neutron fluences in the patient plane. Results: Our study showed that the dose equivalent at the maze door is at the highest when the jaw are closed and that maximal jaws opening reduces the DE by more than 20%. The neutron dose equivalent at the maze door measured for radiation fields defined by jaws do not differ significantly from the DE measured when MLC determines the same size radiation field. The epithermal capture reaction rate measured using different jaw openings differs by approximately 10%. When an MLC leaf is inserted into a fixed geometry for one opening of the jaws, an increase of the epithermal neutron capture reaction rate in Indium activation detectors was observed. Conclusions: There is no significant difference in the neutron DE when MLC defines radiation field instead of jaws. This leads to the conclusion that the overall number of neutrons remains similar and it does not depend on how primary photon beam was stopped-by the jaws or the MLC. An increase of the fast neutron capture reaction rate when MLC leaves are inserted probably originates from the neutron scattering. (C) 2012 American Association of Physicists in Medicine.
