AB  - The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows with tighter windows, which leads to a decrease in air exchange rate and consequently an increase in indoor radon concentration. In case of low exchange rates, dose caused by inhalation of radon and its progeny can exceed external dose originating from the radium content in the surrounding building material. In this paper, surface exhalation rates of radon ( 222 Rn) and thoron ( 220 Rn) from typical building materials used for construction and interior decoration of houses in Serbia were investigated. Surface exhalation rate measurements were performed using the closed-chamber method, while concentrations of radon and thoron in the chamber were continuously measured using an active device, RTM1688-2, produced by SARAD® GmbH. Finally, the impact of the replacement of windows on the indoor radon concentration was estimated.

AB  - Open-faced charcoal canisters have been used for radon measurements for over 40 years. This method is sensitive to temperature, changing radon concentrations, humidity and other parameters, but a comprehensive study dealing with the influence quantities and measurement uncertainty was not available in literature. In this paper, all the identified influence quantities are discussed in detail, uncertainty budget is developed, good practice and bad practice examples are introduced and new recommendations are proposed to optimize the method and reduce uncertainty.

AB  - Lifetimes of low-lying states in 73Ga and 70,72,74Zn were measured using the Recoil Distance Doppler Shift (RDDS) method. These nuclei were produced in deep-inelastic reactions in inverse kinematics with a 208Pb beam impinging on a 76Ge target. Prompt γ rays were detected using the AGATA tracking array coupled to the VAMOS++ spectrometer. Lifetime of the 5/2- state in 73Ga, measured for the first time, provides additional evidence for the existence of a 1/2-, 3/2- ground-state doublet. The lifetimes of the 4+ states in 70,72,74Zn were remeasured in an attempt to understand the discrepancies observed between earlier measurements. Our results are in agreement with those of previous plunger experiments.

AB  - Specific activity of 137Cs, 40K, and 210Pb radionuclides in fifteen selected medicinal herbs from three locations in Central Serbia (two mountains, Kopaonik and Zlatar, and a valley, Sokobanja) was measured using two semiconductor HPGe spectrometer systems. The obtained values are in intervals (<0.3 ÷ 9.7) Bq/kg, (<0.2 ÷ 24.7) Bq/kg, and (<0.2 ÷ 5.7) Bq/kg for 137Cs; in intervals (125 ÷ 1100) Bq/kg, (104 ÷ 872) Bq/kg, and (103 ÷ 954) Bq/kg for 40K, and in intervals (3.6 ÷ 49.0) Bq/kg, (3.9 ÷ 57.9) Bq/kg, and (2.8 ÷ 103) Bq/kg for 210Pb, for herbs from Kopaonik, Sokobanja and Zlatar, respectively. The highest activity measured in individual herbs was: 24.7 Bq/kg for 137Cs (Sokobanja valley), 1100 Bq/kg for 40K (Mt. Kopaonik) and 103 Bq/kg for 210Pb (Mt. Zlatar). The corresponding individual annual effective doses due to ingestion calculated from the measured activity concentrations, of the radionuclides are: in intervals (<1.7 ÷ 82.9) nSv, (<1.4 ÷ 211) nSv, and (<1.1 ÷ 48.7) nSv for 137Cs; in intervals (0.76 ÷ 4.5) μSv, (0.64 ÷ 4.4) μSv, and (0.63 ÷ 4.9) μSv for 40K, and in intervals (1.1 ÷ 18.2) μSv, (1.3 ÷ 21.6) μSv, (0.9 ÷ 38.3) μSv for 210Pb, respectively. The specific activity concentration values of 137Cs and 40K obtained for the investigated herbs are similar to the literature data, while no information was found in literature about specific activity concentration of 210Pb. The all values obtained for individual annual effective dose due to ingestion are less than 100 μSv, which means that the daily use of 200 mL of herbal infusion during a year made from the investigated herbs does not represent a radiological risk for health. However, a high individual annual effective dose of ingestion of 210Pb obtained for some herbs indicate that their consumption in larger amounts 2–3 cups of infusion daily over a year could make the dose to exceed the recommended level, and points to necessity for extensive investigation of 210Pb activity concentration worldwide. © 2019 Elsevier B.V.

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  - The paper deals with the analysis of the annual indoor radon concentrations variations due to different geological parameters of Sjenica community, Western Serbia. The measured 222Rn concentrations were ranging from 10 to 1130 Bq/m3. In 14% of the buildings, the radon action level of 300 Bq/m3 is exceeded, indicating that Sjenica community could be characterized as a radon priority area. Each of 35 measuring location was georeferenced and corresponding lithostratigraphic units and geological period was assigned. Data were analyzed using the multiple linear regression (MLR) method and two predictive models were developed. The MLR model generated by the geological periods explained 17% of the radon variability while, the better one, was the lithostratigraphic MLR model, which explained 52% of the radon variability. Analysis has shown that lithostratigraphic units are important parameters in the prediction of radon levels. © 2019 Carpathian Journal of Earth and Environmental Sciences.

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  - The coincidence summing effect plays an important role in HPGe spectrometry, especially at low source-detector distances, due to a large solid angle; therefore, the calculation of correction factors is necessary. The aim of the research described in this paper was to compare values of correction factors for a 22Na point source obtained using the GESPECOR software package (Monte-Carlo method) and experimentally obtained values. Measurements were performed using a semiconductor HPGe spectrometer and the point source axially positioned at nine different distances from the detector end-cap. For the purpose of determining correction factors, a system of equations was formed, which, besides nuclear data as the input parameters, uses the experimentally obtained values of the total count in the entire spectrum, as well as the counts in the full energy peaks. The system of equations was solved for each particular case and correction factors were determined. By comparing the results obtained using the experimental and Monte-Carlo method, it was found that the correction factors for the 22Na point source have discrepancies less than 3%. The significance of these discrepancies was also verified from a statistical point of view using a Student's t-test. © 2019 RAD Association. All rights reserved.

Dobijene  vrednosti  za  efektivnu  dozu ingestije slične su vrednostima objavljenim u drugim studijama i manje su od 100 μSv, što  upućuje  na  zaključak  da  svakodnevna  upotreba  čajeva  od  analiziranih  lekovitih biljaka sa područja Majdanpeka ne predstavlja značajan radiološki rizik po zdravlje.
AB  - Medicinal plants have a long history in traditional medicine worldwide. However, their use,  as  well  as  the  use  of  plant  products,  must  be  controlled  in  order  to  avoid  the occurrence  of  undesirable  effects  on  human  health.  Specific  activities  of  radionuclides 40K, 137Cs  and 210Pb  in  samples  of  medicinal  plants  were  measured  using  a  semi-conductor HPGe spectrometer system. The average annual effective dose for adults due to  daily  ingestion  of  200  ml  herbal  infusion  prepared  from  medicinal  plants  is determined. In this paper a radiological analysis of 7 selected medicinal plants from the area of Majdanpekis presented. The values obtained for an  effective dose of ingestion are similar to the values published in other studies and are less than 100 μSv, suggesting that  the  daily  use  of   herbal  infusions  from  analyzed  medicinal  plants  from  the Majdanpek area does not represent a significant radiological health risk

AB  - Radon je prirodni radioaktivni gas, čije je prisustvo zbog svojih  karakteristika nemoguće detektovati ljudskim čulima, već ga je neophodno meriti. Iako je otkriven na početku XX veka, kada su i izmerene visoke koncentracije radona u rudnicima srebra u Češkoj, tek je četiri decenije posle pretpostavljena veza izmeĎu visoke koncentracije radona i kancera pluća, da bi se desetak godina kasnije ukazalo na radonove potomke kao moguće uzročnike kancera. Brojne epidemiološke studije su pokazale da radon sa svojim potomcima predstavlja drugi uzročnik kancera pluća posle pušenja. Važnost ispitivanja radona i njegovih potomaka je odmah uočena i u Srbiji, tako da je već na prvom skupu, tada Jugoslovenskog društva za radiološku zaštitu, održanom 1963 godine, bilo nekoliko radova posvećenih merenju koncentracije radona u rudnicima i banjama čime se dominantno bavio Institut za medicinu rada, iz Beograda.

AB  - Radon is natural radioactive gas. It is colourless, tasteless, odourless and therefore it cannot be detected by human senses, but should be measured. It was discovered at the beginning of XX century. At that time, high radon concentrations were measured in the Bohemian silver mines. However it took four decades before a connection between high radon concentration and lung cancer was assumed and one decade more to link radon progeny as a possible cause of lung cancer. Numerous epidemiological studies have shown that radon with its progeny represents second cause of lung cancer after smoking. The importance of investigation of radon and its progeny was acknowledged at the very beginning of Symposiums of Yugoslav society of radiation protection. Thus, already at the first Symposium, held in 1963, there were already several papers published regarding radon concentration measurements in mines and spas. In the first few proceeding of the Symposium the main contribution was from Serbian Institute of Occupational Health. In this publication, an overview of research on radon, published in previous 29 Proceedings of symposiums of Radiation Protection Society, was given. Evolution of actuality of different radon topics was discussed and overview of used measurement techniques was given. Finally, it was estimated in which directions development of radon topics might go.

AB  - Evropski savet je doneo direktivu 2013/59/EURATOM (EU-BSS) po kojoj se nalaže državama članicama EU da imaju ustanovljen radonski akcioni plan, što između ostalog  podrazumeva  i  identifikaciju  radonskih  prioritetnih  zona  (Radon  priority areas), odnosno zona sa različitim nivoom "prioriteta". S obzirom da je neizvodljivo vršiti merenja radona u svakoj kući, potrebno je dizajnirati prospekciju radona kako bi se dobila reprezentativna procena srednje godišnje koncentracije radona u zatvorenim prostorijama na određenoj teritoriji. Nije bitan samo reprezentativan izbor kuća, nego je i nesigurnost merenja i procene srednje godišnje koncentracije potrebno držati što je niže moguće. Nesigurnostn klasifikacije zone određenog prioriteta u nekoj oblasti je stoga kombinacija nesigurnosti pojedinačnog merenja i ekstrapolacije tog merenja na celu oblast. U ovom radu ćemo pokušati da nabrojimo i procenimo izvore nesigurnosti pri klasifikaciji i damo preporuke u cilju smanjenja stepena nesigurnosti. Ovaj rad je urađen u sklopu MetroRadon projekta.
AB  - The EC has laid down directive 2013/59/EURATOM which represents basic safety standards regarding the radon protection of the European citizens. Within the BSS they oblige countries to establish radon action plans which include identification of Radon Priority Areas (RPA). Since it is not feasible to perform indoor radon measurements in each dwelling, it is necessary to carefully design indoor radon survey in order to get representative estimation of annual average indoor radon concentration of the certain territory. It is not sufficient only to have representative selection of dwellings, but it is important  to  keep  uncertainty  of  measurement  and  estimation  of  annual  radon concentration as low as possible. Uncertainty of classification of radon zones is therefore combination of uncertainties coming from a single measurement uncertainty and uncertainty of extrapolation of single or group of measurements to the whole region. In this contribution, we will try to estimate sources of classification uncertainties and to give recommendation in order to reduce level of uncertainty. The research presented in this paper was realized within 16ENV04 MetroRADON project. This project  has  received  funding  from  the  EMPIR  programme  co-financed  by  the Participating States and from the European Union‘s Horizon 2020 research and innovation programme.

Nije bitan samo reprezentativan izbor kuća, nego je i nesigurnost merenja i procene srednje godišnje koncentracije potrebno držati što je niže moguće. Nesigurnostn klasifikacije zone određenog prioriteta u nekoj oblasti je stoga kombinacija nesigurnosti pojedinačnog merenja i ekstrapolacije tog merenja na celu oblast. U ovom radu ćemo pokušati da nabrojimo i procenimo izvore nesigurnosti pri klasifikaciji i damo preporuke u cilju smanjenja stepena nesigurnosti. Ovaj rad je urađen u sklopu MetroRadon projekta., The EC has laid down directive 2013/59/EURATOM which represents basic safety standards regarding the radon protection of the European citizens. Within the BSS they oblige countries to establish radon action plans which include identification of Radon Priority Areas (RPA). Since it is not feasible to perform indoor radon measurements in each dwelling, it is necessary to carefully design indoor radon survey in order to get representative estimation of annual average indoor radon concentration of the certain territory. It is not sufficient only to have representative selection of dwellings, but it is important  to  keep  uncertainty  of  measurement  and  estimation  of  annual  radon concentration as low as possible. Uncertainty of classification of radon zones is therefore combination of uncertainties coming from a single measurement uncertainty and uncertainty of extrapolation of single or group of measurements to the whole region. In this contribution, we will try to estimate sources of classification uncertainties and to give recommendation in order to reduce level of uncertainty. The research presented in this paper was realized within 16ENV04 MetroRADON project. This project  has  received  funding  from  the  EMPIR  programme  co-financed  by  the Participating States and from the European Union‘s Horizon 2020 research and innovation programme.",

AB  - Center for permanent education (CPE) of the "Vinča" Institute of nuclear sciences is a unique educational institution in Serbia. The main objective of the CPE is an additional and complementary education of various profiles of specialists who use radioactive isotopes and sources of ionizing radiation in their everyday work. The CPE aims to improve the quality of its services and strives to continuously follow and introduce modern and new methods of education. The increasing development of information technologies has influenced the development of methods and techniques in the education itself. The latest trend in education is to replace the real laboratories with the virtual ones. The employees of the Center for Permanent Education have, therefore, decided to enrich the CPE courses with virtual software applications. Their use explains the basic concepts of ionizing radiation protection and safety in a simple, easy and fun way. In this paper, we describe some of the virtual software applications that are used in the laboratory curriculum of the CPE courses aimed at furthering education of professionals who work with radioactive sources and generators of ionizing radiation.

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  - Calorimeters for particle physics experiments with integration time of a few ns will substantially improve the capability of the experiment to resolve event pileup and to reject backgrounds. In this paper the time development of hadronic showers induced by 30 and 60 GeV positive pions and 120 GeV protons is studied using Monte Carlo simulation and beam tests with a prototype of a sampling steel-scintillator hadronic calorimeter. In the beam tests, scintillator signals induced by hadronic showers in steel are sampled with a period of 0.2 ns and precisely time-aligned in order to study the average signal waveform at various locations with respect to the beam particle impact. Simulations of the same setup are performed using the MARS15 code. Both simulation and test beam results suggest that energy deposition in steel calorimeters develop over a time shorter than 2 ns providing opportunity for ultra-fast calorimetry. Simulation results for an ``ideal{''} calorimeter consisting exclusively of bulk tungsten or copper are presented to establish the lower limit of the signal integration window.

AB  - With an increase in the awareness of the need to save energy, residents tend to live in dwellings with increasingly tight windows and doors, thus reducing the ventilation rate of indoor air which leads to an increased accumulation of radon indoors. Having in mind that a dose from an exposure to inhaled radon and its progenies can be higher than a dose received from radium in building materials, it is suggested that radon exhalation measurements should receive due attention. In this contribution, the authors compare results gathered using a few methods for radon exhalation measurement and discuss its merits and demerits.

AB  - U radu je merena ekshalacija radona iz bigra iz Niške Banje poznatom po povišenoj
koncentraciji 226Ra. Bigar zbog svoje velike poroznosti i visoke koncentracije radijuma
je idealan materijal za testiranje parametara od kojih zavisi brzina ekshalacije. U radu
je razmatrana zavisnost ekshalacije u odnosu na vlažnost kao i na sprašenost uzorka.
Brzina ekshalacije je merena metodom zatvorene komore, a sama koncentracija radona
aktivnim uređajem. Dobijeni rezultati ukazuju da brzina ekshalacije raste sa povećanjem vlažnosti uzorka i smanjenjem veličine zrna.
AB  - In this contribution, radon exhalation rate from travertine originating from Niška
Banja, Serbia was measured. This particular travertine, with a high 226Ra concentration
and high porosity, is ideal for testing various parameters that can influence radon
exhalation rate. The radon exhalation rate was investigated for different sizes of grains.
Grain sizes were dived into 4 groups: 1) 2.1 - 1.6 mm, 2.) 1.6 - 1.2 mm, 3.) 1.2 - 0.7 mm
i 4.) < 0.7 mm. Influence of the humidity on radon exhalation rate was also
investigated. Samples with the smallest grain size were exposed to 3 different levels of
humidity (dry sample, and two samples in which water content was around 10% and
20% of the mass of dry sample. An accumulation chamber method with an active device
RTM1688-2 was used to estimate radon exhalation rate from continuous measurement
of radon in the chamber. Obtained results indicate that radon exhalation rate is
increasing with an increase of humidity of the sample and with an decrease of grain
size.

AB  - Laundry detergents are chemicals widely used in everyday life, and in numerous industry branches. In order to perceive the radiological aspect of environmental pollution by wastewater, the analysis of laundry detergents available on the Serbian market was undertaken. Laundry detergent samples were measured by means of gamma spectrometry and the results are presented in this paper. Analysis of the obtained activity concentrations showed that laundry detergents in Serbia mostly fulfill the international recommendation and requirements regarding the phosphate content. Besides that, the content of the detected radionuclides in laundry detergent samples indicates the minor radiological risk to the environment via wastewaters.

AB  - The half-life of Ne-19 was measured using a real-time digital multiparametric acquisition system, providing an accurate time stamp and relevant information on the detector signals for each decay event. An exhaustive offline analysis of the data gave unique access to experimental effects potentially biasing the measurement. After establishing the influence factors impacting the measurement such as after-pulses, pile-up, gain, and baseline fluctuations, their effects were accurately estimated and the event selection optimized. The resulting half-life, 17.2569 +/- 0.0019((stat)) +/- 0.0009((syst)) s, is the most precise up to now for Ne-19. It is found to be in agreement with two recent precise measurements and not consistent with the most recent one [L.J. Broussard et al., Phys. Rev. Lett. 112, 212301 (2014)] by 3.0 standard deviations. The full potential of the technique for nuclei with half-lives of a few seconds is discussed.

AB  - In this paper we investigated the effects of Fe-doping of the anatase TiO2 (1 0 1) surface on the crystal structure, electronic and optical properties, and impurity formation energy by means of density functional theory (DFT). The calculations were performed by the SIESTA DFT code and were carried out by using Troullier-Martins pseudopotentials for the 12-electron valence configuration (3s(2)3p(6)3d(2)4s(2)) of Ti atom, 6-electron valence configuration (2s(2)p(4)) of O atom and 8-electron valence configuration (3d(6)4s(2)) of Fe atom. We used a double- zeta basis set including polarization functions. All calculations were spin-polarized. The mechanism of narrowing the band gap and increasing the photocatalytic activity in the visible light region, of the doped TiO2 is discussed by investigating the density of state. The band gap decreases as the concentration of the dopant increases. The Partial Density of States (PDOS) is not the same in the case of spin-up state or spin-down state. Enhanced optical absorption, for light polarized in the z direction (parallel to the surface normal) is clearly observed for Fe doped as compared to the pure anatase TiO2 and the optical absorption is found to increase with the increase in the Fe concentration. The DFT results indicate that the source of the increasing photocatalytic activity in the visible light region of the Fe doped material is due to the introduction of additional electronic states within the band gap. Since the Fe atoms are more stable in Ti substitutional lattice positions for the entire range of Fermi energy E-F over the band gap, only this substitutional position is considered. We hope that our results will highlight a route to improved electronic and optical properties of anatase TiO2 for industrial applications. (C) 2017 Elsevier B.V. All rights reserved.
