AB  - The estimation of the radioactivity levels of materials utilized in construction sectors is crucial in the assessment of possible radiological hazards to human health. In the paper, the results of gamma spectroscopy study of 211 zircon, 425 sand, 781 lime, 348 perlite, 2692 cement, 232 calplex, 968 gypsum, 2741 granite and 21 coal fly ash samples gathered from different countries and imported in Serbia in period 2006-2016 were presented. In order to assess the radiological impact from the investigated samples, the activity concentration index I-RP112 for all samples was ascertained. This research yields insight into the radioactive content in a variety of building materials of different origin. The obtained results were discussed on the basis of relevant national and international legislation and guidance and compared with the corresponding results in the literature.

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
pokazuju dobro slaganje sa nedavnim ispitivanjem emanacije radona iz zemljišta na

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

mehaničkog sastava zemljišta i sadržaja humusa i pristupačnog fosfora i kalijuma.

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
Bq/kg), 226Ra (44.7 Bq/kg), 232Th (55.5 Bq/kg) and 137Cs (29 Bq/kg) at 30 cm depth

AB  - The main aim of this paper was to compare different methods of preparing water samples for tritium analysis by ultra-low-level background liquid scintillation counter, Quantulus 1220. 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  - This work presents the first estimate of the radioactivity and sediment deposition rate of the Drenova reservoir. The radioactivity and sedimentation rate were computed applying the Pb-210 and Cs-137 methods. Samples of Pb-210 and Cs-137 were taken from four boreholes drilled in the Drenova reservoir in June 2010. Vertical distribution of the natural and artificial radionuclides in four boreholes was examined using a gamma spectrometry measurement with HpGe detectors, Gamma X type (10 keV-3 MeV). Activities ranging from 122-8 Bq/kg were found for Pb-210, and from 140-0.8 Bq/kg for Cs-137. The sedimentation rate in the Drenova reservoir varied from 1.96 to 2.90 cm per year for unsupported Pb-210 and 0.47 to 5.33 cm per year for Cs-137.

AB  - This article reflects a partial resume of research in applied nuclear physics performed in our country during the last 50 years. As the first example we can quote the successes of B. Lalovic and V. Ajdacic in developing and applying new instrumentation for nuclear measurements. V. Ajdacic developed the long pipe method for the absolute measurement of neutron flux in power reactors. Together with B. Lalovic, he managed, among the first few people in the world, to produce semiconductor Ge(Li) spectrometers. Practically all of the measuring equipment currently being used by the Novi Sad nuclear physics group has been purchased with funds obtained for radioecological investigations, so that actually the applied nuclear spectroscopy kept alive the experimental work. Background reduction, sensitivity increase, detection efficiency calibration and development of coincidence techniques are research directions through which this group tries to measure as low as possible radionuclide concentrations, as well as the probability of exotic rare nuclear processes. Very strong radiation sources in Vinca have been used for some decades for sterilization of food and medical equipment. Hyperfine interactions of nuclei with the electric and magnetic fields of their crystal environment give extensive possibilities to investigate phenomena in solid-state physics and new materials. The highly advanced techniques of perturbed angular correlations and Mossbauer spectroscopy were adopted here as bridges between nuclear and condensed matter physics. The bridges are partly destroyed, partly still standing, but almost nobody passes them.

The depth of the laboratory is 12 m, equivalent to 30 m of water with an area of 45 m(2). The whole of the laboratory is hermetically lined with 1 mm Al foil and is ventilated with filtered air. Radon concentrations were measured with the CR-39 detector as well as via the gamma-ray spectroscopic measurements. The radon concentrations in the air were achieved to 20 Bqm(-3) and reduction of secondary and tertiary cosmic-ray fluxes is five times when ventilation, filtering and sealing was applied.

Both the slow and the fast anticoincidence gating modes were tested, the slow mode being found better suited for general low-level spectroscopy applications. In long runs the stability of the system in this mode is satisfactory. The anticoincidence action of the NaI(Tl) shield lowers the integral background of the iron shielded HPGe detector in the energy range from 30 keV to 2 MeV by a factor of 6.5, and suppresses the continuum above 150 keV by a factor larger than 10.

AB  - The gamma spectrum of Cs-137 was measured by means of a low-level shielded and Compton-suppressed HpGe spectrometer. The gamma line with the energy 283.4 keV and absolute intensity of 5.3(14)X10(-6) was found. It was concluded that the 283.4 keV intermediate level in Ba-137 [seen earlier in (n,ngamma) measurements] is populated in the beta decay of Cs-137 with the comparative half-life of log ft=15.3(3).
