AB  - Most studies focused on thoron have shown that indoor thoron originates mainly from building materials and that thoron concentrations exponentially decrease with a distance from a wall surface. On the contrary, due to longer half-lives of thoron progenies, 212 Pb and 212 Bi, which are mainly responsible for the bronchial dose, it is expected that their spatial distribution is homogeneous. Therefore, direct measurements of thoron progeny concentrations or direct thoron measurement and determination of thoron equilibrium factor are necessary for accurate dose assessment. In this paper, we have optimized and validated a reliable and inexpensive method for direct measurement of thoron progenies concentrations based on an air filtration followed by gamma spectrometry measurements. With simultaneous measurements of indoor thoron by the RAD7 active device, the equilibrium factor for thoron in 15 different investigated dwellings was estimated. Obtained results for the equilibrium equivalent thoron concentrations in the range from 0.277 Bq/m 3 to 11.34 Bq/m 3 and thoron equilibrium factor in the range from 0.0047 to 0.098 with arithmetic mean value of 0.034 are in good agreement with already published results. © 2019 Elsevier Ltd

AB  - Nedavne  studije  koje  se  bave  problemom  torona  pokazuju  da  toron  u  vazduhu zatvorenih prostorija dominantno potiče od upotrebljenih građevinskih materijala za izradu i pokrivanje zidova i podova i da koncentracija torona eksponencijalno opada sa rastojanjem od površine zidova. Međutim, usled dužeg perioda poluraspada, toronovi potomci 212Pb i 212Bi imaju homogenu prostornu distribuciju i mogu značajno doprineti bronhijalnoj dozi. U ovom radu je razvijena metoda direktnog određivanja koncentracije toronovih potomaka u vazduhu koja se zasniva na gama-spektrometrijskim merenjima filter papira uz detaljnu analizu i optimizaciju vremena usisavanja, hlađenja i merenja na HPGe detektorskim sistemima. Metoda je validovana kroz uporedna merenja sa aktivnim monitorom koji se najčešće koristi za merenje ravnotežne ekvivalentne koncentracije torona. Ovakav način ispitivanja toronske ravnoteže će doprineti preciznom određivanju doze koju primi stanovništvo od inhalacije torona i potomaka, naročito zbog poznate problematike mogućnosti merenja torona kao kratkoživećeg radionuklida. Rezultati preliminarnog istraživanja problema torona u petnaest odabranih kuća pokazuju da su procenjene doze od udisanja torona uporedive sa dozama koje stanovništvo primi od udisanja radona i da toron mora biti obuhvaćen u budućim monitorinzima radona.

AB  - Monitoring of environmental samples, drinking and surface waters, is continuously
carried out, demanding development of methods that are both reliable and accurate on
one side, but as simple and fast as possible, on the other. Screening tests such as gross
alpha/beta activity measurements in water samples are one liquid scintillation counting
(LSC) technique widely used as an efficient tool for radiological assesment and
estimation whether water sample needs further analysis or not. In this paper,
establishment of rapid gross alpha/beta screening technique in waters has been
presented, which assumes modification of conventional ASTM D 7283-06 method, since
samples were directly mixed with liquid scintillation cocktail, without any sample
pretreatment. Method’s optimization involved sample-to-cocktail ratio determination
based on the achieved detection limit and sample’s quench level. Optimal value of Pulse
Shape Analysis (PSA) discriminator that considerably improves performance of LSC
technique through alpha/beta spectra separation during radiological quality
measurements of drinking waters has also been investigated. Results of calibration
experiments and method’s validity measurements on spiked samples with 241Am and
90Sr/90Y aqueous standards are presented. Achieved detection limits for 300 minutes
of counting are MDAα=0.294(11) Bq l-1 and MDAβ=0.405(5) Bq l-1, in alpha and beta
window, respectively. Direct alpha/beta method provides deviations up to 40% from
reference values, but it offers advantages over conventional alpha/beta measurements,
it is ultra fast, simple and inexpensive test for efficient screening of water samples.
AB  - Rutinski monitoring pijaćih i površinskih voda sprovodi se kontinuirano i nameće
potrebu za razvojem metoda koje su, s jedne strane, pouzdane i tačne, ali istovremeno,
jednostavne i brze. Screening testovi radi procene ukupne alfa/beta aktivnosti u
uzorcima voda, jedna su od često primenjenih tehnika tečne scintilacione
spektroskopije, kojima se efikasno može utvrditi da li uzorak zahteva dalju radiološku
analizu ili ne. U radu je predstavljena optimizacija brze direktne metode za ispitivanje
ukupne alfa/beta aktivnosti u vodama, uz prikaz i diskusiju postignutih granica
detekcije. Ova metoda je modifikacija standardne test metode ASTM D 7283-06 za
ispitivanje ukupne alfa i beta aktivnosti i podrazumeva direktno mešanje uzorka vode sa
scintilacionim koktelom. Na taj način, uzorak je spreman za merenje bez prethodne
pripreme koja, prema standardnim metodama, obično podrazumeva duge procedure
poput uparavanja do suvog ostatka. Optimizacija metode sastoji se u određivanju
optimalnog odnosa uzorak: scintilacioni koktel na osnovu granica detekcije (MDA) u
alfa i beta kanalima, kao i nivoa prigušenja u uzorcima, uzimajući u obzir i maksimalni
kapacitet određenog koktela. Podešena je vrednost PSA (Pulse Shape Analysis)
diskriminatora u cilju optimalne separacije alfa i beta spektara i redukcije pozadinskih
efekata. Kalibracija i validacija metode je izvršena standardnim referentnim materijalima, rastvorima 241Am i 90Sr/90Y. Utvrđeno je da za 300 minuta merenja tečnim
scintilacionim brojačem, mogu se izmeriti koncentracije aktivnosti koje premašuju
vrednosti MDAα=0,294(11) Bq l-1 i MDAβ=0,405(5) Bq l-1 u alfa i beta kanalima,
respektivno. Rezultati validacije metode pokazuju da maksimalna relativna odstupanja
mogu iznositi do 40%, što je prihvatljivo, uzimajući u obzir da metod nije predviđen za
precizno merenje koncentracija aktivnosti pojedinih radionuklida, već za celokupnu
procenu radiološke bezbednosti uzoraka voda.

vrednosti MDAα=0,294(11) Bq l-1 i MDAβ=0,405(5) Bq l-1 u alfa i beta kanalima,
respektivno. Rezultati validacije metode pokazuju da maksimalna relativna odstupanja
mogu iznositi do 40%, što je prihvatljivo, uzimajući u obzir da metod nije predviđen za
precizno merenje koncentracija aktivnosti pojedinih radionuklida, već za celokupnu
procenu radiološke bezbednosti uzoraka voda.",

AB  - Radon 222Rn is formed as a product of decomposition of 226Ra, it is radioactive isotope
that is soluble in water and represents one of the most common natural sources of
radiation. Monitoring of 222Rn in drinking water is important to continuously implement
due to hydrogeological studies and also radiological risk assessment. There are
different methods of measuring radon in water. Alpha spectrometric methods are the
most commonly used, especially RAD7 as a portable alpha spectrometer that allows on
field measurements. Liquid scintillation spectrometry (LSC) is often preferred as a
technique of measuring 222Rn in water samples. The method itself is carried out by
mixing water samples with an organic scintillation cocktail. The cocktail causes the
radon diffusion from the aqueous solution to the organic phase because radon has a
higher affinity for the organic phase, thus preventing the emission of radon from the
water. In addition to the before mentioned methods, a gamma spectrometric method
that uses the secular radioactive equilibrium of radon and its daughter products gave us
satisfactory results. In this paper, the advantages and disadvantages of four different
methods of measuring radon in water will be shown: two LSC methods (monophase and
two-phase), RAD7 and gamma spectrometric method. All three methods have very low
minimal detectable activity (MDA) values, lower than 1 Bq l-1. In addition to the
different measurement techniques, a comparison of two methods for sampling of water
will be presented also on few examples.

AB  - Geogeni radonski potencijal koji izdvaja radon u podzemnim slojevima kao dominantan
uzrok akumulacije radona u zatvorenim prostorijama i koji je nezavisan od ljudskog
uticaja i vremenski konstantan u geološkim okvirima predstavlja glavni alat za
iznalaženje radonom ugroženih područja. U nedostatku podataka za permeabilnost
zemljišta za radon i malog broja merenja radona u zemljištu, upotrebljena je
multivarijantna analiza velikog broja raspoloživih geohemijskih podataka, merenja
radioaktivnosti zemljišta i koncentracija aktivnosti radona u zatvorenim prostorijama
datih lokacija na području Vojvodine. Nekoliko uporedivih metoda iz ROOT okvira za
analize softverskog paketa TMVA je korišćeno za analizu zavisnosti koncentracije
radona u zatvorenom od mnoštva ulaznih varijabli. BDTG kao najpodobnija metoda je
pokazala da su varijable sa najvećim uticajem na koncentraciju radona u zatvorenim
prostorijama pored sadržaja ukupnog azota, koncentracije aktivnosti radionuklida u
zemljištu na profilu dubine od 30 cm i sadržaj humusa i gline. Dobijeni rezultati

AB  - The most dominant source of indoor radon is the underlying soil, so the enhanced levels
of radon are usually expected in mountain regions and geology units with high radium
and uranium content in surface soils. Laboratory for radioactivity and dose
measurement, Faculty of Sciences, University of Novi Sad has rich databases of natural
radionuclides concentrations in Vojvodina soil and also of indoor radon concentrations
for the region of Vojvodina, Northern Province of Serbia. In this paper, we present the
results of correlative and multivariate analysis of these results and geochemical
characteristics of soil in order to estimate the geogenic radon potential. The correlative
and multivariate analysis were done using Toolkit for Multivariate Analysis software
package TMVA package, which uses several comparable multivariate methods for our
analysis. The evaluation ranking results based on the best signal efficiency and purity,
show that the Boosted Decision Trees (BDT) and Multi Layer Preceptor (MLP), based
on Artificial Neural Network (ANN), are multivariate methods which give the best
results in the analysis. The BDTG multivariate method shows that variables with the
highest importance are radio-nuclides activity on 30 cm depth. Moreover, the
multivariate regression methods give a good approximation of radon activity using full
set of input variables

AB  - In this paper, we performed, for the first time, detailed study of Vojvodina’s soil in
order to explore possible correlations of soil geochemical characteristics and
radionuclide activity concentrations. The aim of this study is to analyze the content of
natural radioisotopes 238U, 226Ra, 232Th and 40K, as well as artificial radioisotope 137Cs
in all soil types originated from the same parent material – loess. The sampling
locations were selected so that they are proportionately represented all
geomorphological units: two mountains, four loess plateaus, three loess terraces, four
alluvial plains, two sandstone terrains. The process of genesis of soil and cultivation
mode plays a dominant role on the characteristics of the soil. However intensive
agricultural production and the use of high mineral fertilizers have caused that the
same type of soil contains different concentrations of available phosphorus and
radionuclides. Comparison of activity concentrations between different types of soil
confirmed that the presence of clay mostly contributes to radionuclides content in the
soil. The main conclusion is that measured maximal activity concentrations for 238U (87

AB  - Results and conclusions of interlaboratory comparison of indoor radon in 2015 in Serbia are presented. The participants were three accredited laboratories from Serbia: Serbian Institute of Occupational Health Dr Dragomir Karajovic, Laboratory for Radioactivity and Dose Measurements at the Faculty of Sciences, University of Novi Sad and Radiation and Environmental Protection Department, Vinca Institute of Nuclear Science. The laboratories make use of the same method for radon measurement, using charcoal canisters according to US Environmental Protection Agency (EPA) protocol 520/5-87-005.

AB  - Thoron gas and its progeny behave quite differently in room environments, owing to the difference in their half-lives; therefore, it is important to measure simultaneously gas and progeny concentrations to estimate the time-integrated equilibrium factor. Furthermore, thoron concentration strongly depends on the distance from the source, i.e. generally walls in indoor environments. In the present work, therefore, the measurements of both thoron and radon gas and their progeny concentrations were consistently carried out close to the walls, in 43 dwellings located in the Sokobanja municipality, Serbia. Three different types of instruments have been used in the present survey to measure the time-integrated thoron and radon gas and their progeny concentrations simultaneously. The equilibrium factor for thoron measured close to the wall, F-Tn(W), ranged from 0.001 to 0.077 with a geometric mean (GM) [geometric standard deviation (GSD)] of 0.006 (2.2), whereas the equilibrium factor for radon, F-Rn,F- ranged from 0.06 to 0.95 with a GM (GSD) of 0.23 (2.0).

AB  - In order to optimize the design of a national survey aimed to evaluate radon exposure of children in schools in Serbia, a pilot study was carried out in all the 334 primary schools of 13 municipalities of Southern Serbia. Based on data from passive measurements, rooms with annual radon concentration GT 300Bq/m(3) were found in 5% of schools. The mean annual radon concentration weighted with the number of pupils is 73Bq/m(3), 39% lower than the unweighted 119Bq/m(3) average concentration. The actual average concentration when children are in classrooms could be substantially lower. Variability between schools (CV=65%), between floors (CV=24%) and between rooms at the same floor (CV=21%) was analyzed. The impact of school location, floor, and room usage on radon concentration was also assessed (with similar results) by univariate and multivariate analyses. On average, radon concentration in schools within towns is a factor of 0.60 lower than in villages and at higher floors is a factor of 0.68 lower than ground floor. Results can be useful for other countries with similar soil and building characteristics.

AB  - Between 2008 and 2011 a survey of radon (Rn-222) was performed in schools of several districts of Southern Serbia. Some results have been published previously (Zunic et al., 2010; Carpentieri et al., 2011; Zunic et al., 2013). This article concentrates on the geographical distribution of the measured Rn concentrations. Applying geostatistical methods we generate school radon maps of expected concentrations and of estimated probabilities that a concentration threshold is exceeded. The resulting maps show a clearly structured spatial pattern which appears related to the geological background. In particular in areas with vulcanite and granitoid rocks, elevated radon (Rn) concentrations can be expected. The school radon map can therefore be considered as proxy to a map of the geogenic radon potential, and allows identification of radon-prone areas, i.e. areas in which higher Rn radon concentrations can be expected for natural reasons. It must be stressed that the radon hazard, or potential risk, estimated this way, has to be distinguished from the actual radon risk, which is a function of exposure. This in turn may require (depending on the target variable which is supposed to measure risk) considering demographic and sociological reality, i.e. population density, distribution of building styles and living habits.

AB  - The purpose of this work is to evaluate the radiation exposure to nuclear medicine (NM) staff in the two positron emission tomography-computed tomography centres in Serbia and to investigate the possibilities for dose reduction. Dose levels in terms of H-p(10) for whole body and H-p(0.07) for hands of NM staff were assessed using thermoluminescence and electronic personal dosemeters. The assessed doses per procedure in terms of H-p(10) were 4.2-7 and 5-6 mu Sv, in two centres, respectively, whereas the extremity doses in terms of H-p(0.07) in one of the centres was 34-126 mu Sv procedure(-1). The whole-body doses per unit activity were 17-19 and 21-26 mu Sv GBq(-1) in two centres, respectively, and the normalised finger dose in one centre was 170-680 mu Sv GBq(-1). The maximal estimated annual whole-body doses in two centres were 3.4 and 2.0 mSv, while the corresponding extremity dose in the later one was 45 mSv. Improvements as introduction of automatic dispensing system and injection and optimisation of working practice resulted in dose reduction ranging from 12 up to 67%.

Three methods of sample preparation for low-level tritium measurement have been implemented in the Nuclear Physics Laboratory in Novi Sad: electrolytic enrichment, direct method without electrolytic enrichment and sample Oxidizer 307 method. The examined fresh water samples were rainfall collected during 6 months and water from a stream in the Vinca nuclear research center collected over 3 months. The obtained results using these three methods showed satisfying agreement. The appropriate measuring time by LSC for each sample prepared according to different methods has been determined.

AB  - Gross alpha and beta activities, H-3, Ra-226, Th-232 and K-40 activities were measured in bottled mineral water produced in Serbia in order to assess its radiological quality. In 11 samples of tap water and in 1 sample of spring waters gross alpha and beta activity were determined. The natural activity concentration of alpha and beta emitting radionuclides are within the range recommended by World Health Organization. The tritium concentration in bottled mineral waters ranged from 0.023 +/- 0.012 to 0.046 +/- 0.006 Bq l(-1). The activity of Ra-226, Th-232 and K-40 were below the minimum detectable activity. In order to evaluate the annual effective dose for different classes of age, a conservative dosimetric calculation was carried out. (C) 2012 Elsevier Ltd. All rights reserved.

AB  - We investigated the biochemical and ultrastructural changes in the liver of the freshwater fish, European perch (Perca fluviatilis), in response to Aphanizomenon flos-aquae bloom in the Gruza Reservoir, Serbia. The activities of total manganese- and copper zinc-containing superoxide dismutase (Tot SOD, Mn-SOD, Cu/Zn-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and biotransformation phase II enzyme glutathione-S-transferase (GST), as well as concentrations of total glutathione (GSH) and sulfhydryl (-SH) groups were examined before and during the bloom period. Mn-SOD activity was significantly higher, while the activities of Cu/Zn-SOD, CAT and GSH-Px and the concentration of the -SH groups were significantly lower during the bloom. The ultrastructure of the liver revealed necrotic and apoptotic damage to the hepatocytes during the bloom period. Our work represents the first study to report the influences of an Aphanizomenon flos-aquae bloom in the Gruza Reservoir on antioxidant biomarkers and on histopathological alterations in the liver of the freshwater fish European perch (Perca fluviatilis).
