AB  - Renewable energy resources are of great interest for prevention and mitigation of the climate change effects. Here is presented a study on the utilization of green energy fuels derived from available resources as prevent for diminishing potential environmental pollution levels influencing this change. The atmospheric particulate matter composition, also recognized as hazardous and most responsible for human health and premature deaths would be adequate parameter to be followed in these terms. A biomass burning contribution to the aerosol fraction with particles less than 2.5 μmin diameter (PM2.5) was assessed in the Belgrade residential area. Daily PM2.5 aerosol samples collected on membrane Teflon filters over four seasons were analyzed by PIXE (proton induced X-ray emission) nuclear analytical technique and multi-wavelength (405-1050 nm) light attenuation measurements. Results have indicated presence of several biomass and biofuel related tracer elements like Ni, V, Cu, Zn, Ti, Mn, and Cr and significant contents of Pb and Cd, proving that it may be used for detection of their presence in the mix of energy related emissions. Black carbon concentration was also a good indicator candidate as its values have shown strong seasonality, although for more sophisticated recognition of specific species, additional analysis would be necessary. Receptor modeling using positive matrix factorization (EPA PMF 5.0) revealed about 40% of PM2.5 mass belonging to the biomass-related emission sources coming from the energy production sector. Besides the black carbon measured at wavelengths up to 600nm, K was recognized as a main tracer for biomass sources like wood and biofuels. A V/Ni ratio, characteristic for heavy oil burning, was noticed in all seasons indicating contribution of industrial emission sources during the summer in addition to its appearance in the heating season. Nevertheless, recently encouraged use of the individual biofuels such as biochar, bio-oil, methanol, and crude glycerol, could not be distinguished by applied methodology from the mixed ones. Use of HP Ge spectrometry for 210Pb/Pb ratio and K concentrations determination should be considered in specific cases only, due to differences in sampling periods and sample preparation procedures for radionuclides and PM2.5 elemental analysis. Obtained results support the use of nuclear analytical techniques for analysis as well as development of new tools and techniques for simple and efficient control of biofuel combustion products in emission exhausts, having in mind the intention of their more frequent application in everyday life in urban areas.

AB  - The health effects attributed to exposure to ambient PM2.5 concentrationsabove 10 μg/m3by using the AirQ+ modeling software were assessed. Thehourly concentrations of PM2.5 were collected from 13 air pollutionmonitoring stations in the Belgrade district during Jun and July 2021.,which were further used as input data for the AirQ+software. The averageconcentration of PM2.5 for two-month monitoring from all sampling sites inthe city was 14.8 μg/m3, the maximum daily concentration was 55.7 μg/m3,while the maximum concentration per hour was 365 μg/m3. The spatialdistribution of concentrations was mapped using geostatistical interpolation,revealing hotspots within the city centre and industrial area of the district.The burden of disease, such as stroke, ischemic heart disease (IHD), chronicobstructive pulmonary disease (COPD) and lung cancer (LC), due to theambient PM2.5 pollution was evaluated according to the WHO methodologyfor health risk assessment of air pollution. The model used for thisassessment is based on the attributable proportion defined as the section ofthe health effect related to exposure to air pollution in an at-risk population.The estimated attributable proportion was 19.4% for stroke, 27.2% for IHD,15.3% for COPD and 9.0% for LC. The estimated number of attributablecases per 100,000 population at risk, due to PM2.5 air pollution, for stroke,IHD, COPD, and LC, was 28, 34, 15, and 8, respectively.

AB  - In recent years, due to economic and political instability around the world, there has been growing concern over the possible infiltration of counterfeit, fraudulent and suspect items (CFSIs) into the nuclear supply chain. CFSIs do not undergo the same rigorous quality assurance procedures as legitimate items, and deviate from prescribed specifications. Within the nuclear supply chain, CFSIs can diminish the integrity of equipment, systems, structures, components or devices that contribute to nuclear safety and/or nuclear security. The inadvertent introduction or malicious insertion of CFSIs within the nuclear supply chain could lead to the occurrence of a nuclear security event. Prevention and risk assessment are essential in containing the security consequences of illicit trade, and technology could play a central role in monitoring – with the aim of reducing the resources available to politically motivated and terrorist actors. Therefore, it is necessary to develop measures to mitigate the nuclear security implications of CFSIs that have infiltrated the nuclear supply chain, or prevent their introduction altogether. Quality Assurance requirements for each supplier category and the quality classification of the procured item or service should be part of CFSI Program as an integral part of the Integrated Management System and Quality Assurance Program. It is of great importance to make comprehensive review of existing international legislations and regulations which refers to CSFIs and to look into procurement process in the light of nuclear security implications of CFSIs.

AB  - The sources of different pollutants contributing to ambient PM2.5 in the Banja Luka (Bosnia and Herzegovina) suburban area were estimated. From January 2016 to March 2017, a total of 140 daily PM2.5 filter samples were collected and analyzed by complementary nondestructive analytical techniques. Concentrations of Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, and Pb were determined by energy dispersive X-ray fluorescence technique while black carbon concentration was estimated using multi-wavelength absorption optical measurements. Evaluation of the emission sources was performed based on the obtained PM2.5 composition data using positive matrix factorization model. The results indicate five main groups of sources contributing to the annual mean PM2.5 concentration (38.7 µg/m3): secondary sulfur/coal combustion 35.4% (11.8 µg/m3), biomass combustion 26.1. % (9.2 µg/m3), road salts/heavy oil 21.2% (7.5 µg/m3), soil dust 1.1% (0.4 µg/m3) and traffic emissions less than 0.05%. Black carbon originating from diesel fuel and biomass burning was differentiated by applied optical technique and included into PMF analysis. The approach and results of the field study are unique and significant contribution to the air quality management in this area.Copyright © 2022 American Association for Aerosol Research

AB  - Mountain ecosystems are going through changes due to numerous physical-chemical processes in the environment rather than the anthropogenic activities. Primordial radioactivity of rock and soil material migrates and fractionates in other environmental sections like waters, air and biota. Having a feature to accumulate different minerals and trace element present in soil and three substrates, fungi indicates their composition and related processes. The aim of this study is uptake of radionuclides by fungi in the schist soil of the Stara Planina, mountain famous for biodiversity as well as for enhanced natural radioactivity areas. Samples of various fungi species (stipes and cups) and their soil substrates have been collected in summer season 2019. Collected soil samples are pedologically characterized and analysed by gamma-spectrometry (HP Ge) after the secular radioactive equilibrium had been reached. Soil characterization has shown the share of coarse fragments, sand, silt and clay in the schist (shale) structure while pH value was 4.80-5.33 and organic carbon content 3.10%. The content of significant natural radionuclides 40K, 226Ra, 232Th, 238U and manmade 137Cs was (in Bq/kg) was 500±30, 27±2, 26±2, 32±4, 1.6±0.2 respectively. Dried fungi samples were analysed by gamma spectrometry showing the natural radionuclide content in wide range of values. Obtained results indicate dependence of the radionuclides uptake from the substrate on their abundance in schist soil type as well as the fungus specie physiology. Slight difference was observed in results between content in species with different types of nutrient uptake (mycorrhizal and saprobic). The 137Cs content varied from 2-20 Bq/kg. Further knowledge on the local population habits in use of edible fungi species would enable dose assessment for the representatives of the public and contribute to a further research on the Stara Planina mountain ecosystem.

AB  - Light Absorbing Carbon (LAC) or Black carbon (BC) is one of the most important components of fine particulate matter (PM2.5), which is formed through the incomplete combustion of fossil fuels, biofuels and biomass. Based on a number of studies, it has been shown that carbonaceous particles significantly affect air quality/environment and they are an important factor in the carbon cycle and climate change. BC, as one of the constituents of carbonaceous respirable particles, has the property of absorbing light and leads to an increase in the annual average air temperature. Therefore, its quantitative analysis and differentiation for determination of potential radiative effects is extremely important. The BC concentration is usually determined by using thermal or optical methods. In this paper, the results of the application of multiwavelength optical technique for BC estimation which is based on measuring the intensity of absorption/transmission of light through samples of deposited aerosols on PTFE filters, are presented. Sample collection was conducted at Belgrade suburban background site, in heating and nonheating seasons, using low-volume air samplers. In order to estimate the BC concentration of different particle diameters, measurements were performed by using the MABI ANSTO instrument, with LEDs that emit light at seven different wavelengths: 405 nm, 465 nm, 525 nm, 639 nm, 870 nm, 940 nm and 1050nm. The measurement procedure is started by determination of the value of light transmission I0 through an unexposed or blank filter at different wavelengths. After sampling, the estimation of light transmission I through the exposed filters was performed. Before estimation of BC concentration, the light-absorbing coefficient (babs) at each wavelength was determined separately. More intense variations in the values of babs were observed, which most likely occur due to the change in the nature of the pollution sources at the sampling site. The accuracy of the BC concentration depends on the value of the mass absorption coefficient (ε) estimated experimentally and whose values are compared with the predefined manufacturer values. BC generated by combustion at lower temperatures is better absorbed at shorter wavelengths. On the other hand, BC generated through high-temperature processes is better absorbed in the infrared region of the electromagnetic spectrum. Therefore, the differences of BC concentrations at two boundary wavelengths: 405 nm and 1050 nm were analyzed. Finally, seasonal BC variations were observed, with increased values in the winter and autumn periods compared to the summer period.

AB  - Besides the evident harmful impact to human health, black carbon (BC) is considered as second important contributor to climate change due to its sunlight absorption and warming effects. It is a major component of fine atmospheric particulate matter emitted during the incomplete combustion of fossil fuels and biomass burning emissions from both natural and anthropogenic sources. Atmospheric carbon was recognized in forms of soot, black carbon, elemental carbon, inorganic carbon, organic carbon, brown carbon, etc, depending on the origin and absorption characteristics. Measurement methodologies for BC analysis in aerosol samples are mostly based on optical and thermal properties of carbon species. Here are presented results of the application of the optical analytical technique which relies on the multi-wavelenght light attenuation by black carbon component of fine particulate matter deposited on filter media. For that purpose, standard polytetrafluoroethylene (PTFE), quartz and carbon nanotube filters with different qualitative features and pore diameters were exposed to fine aerosol fraction at urban background monitoring site in heating and non heating seasons, using low-volume air samplers with 2.3 m3/h air flow. A multi wavelength absorption black carbon instrument (MABI) with 405 nm, 465 nm, 525 nm, 639 nm, 870 nm, 940 nm and 1050 nm LEDs was used for blank and exposed filters analysis and black carbon evaluation. Differences in obtained BC values are discussed in relation to various absorption potential of different filter media, taking into account absorption coefficients dependence on the wavelength and density. Main advantage of this method is simplicity and complementarity with nondestructive nuclear analytical techniques (EDXRF, PIXE) for elemental analysis of fine aerosol fraction on specific filter media. Differentiation between black carbon coming from fossil fuels combustion and from biomass burning sources would be additional information valuable for source apportionment analysis using positive matrix factorization and reliable discussion of air pollution observed at selected receptor site.

AB  - Positive matrix factorization (PMF) is a dimension reduction method used to model the covariance structures of observable variables in order to impel a smaller number of latent nonnegative factors. It resolves receptor modeling problem, which is based on the chemical mass balance equation (CMB) and may discover hidden patterns in the environmental data, where each extracted factor is accompanied by an actual source of emission. In this paper, PMF source apportionment analyses of fine aerosol fraction (PM2.5 mode) at Belgrade suburban background site, in 2016/17 year, have been performed by processing a data set of 130 PM2.5 mass concentrations and twenty-one elemental concentrations and soot concentrations in each PM2.5 sample (mode). The PM2.5 mass concentrations in collected samples have been determined following SRPS EN 12341:201 procedure, elemental concentrations were obtained by PIXE alanytical technique in the frame of the regional IAEA project, in the Institute of Nuclear Research, Hungarian Academy of Sciences, and soot concentrations were analyzed by smoke stain reflectometry in accordance with ISO 9835:1993 (E). The EPA PMF program ver 5.0, was used to solve the PMF model. Since the determination of an optimal PMF solution is a strongly heuristic procedure, there is a necessity of finding a more quantitative ways to reduce the arbitrariness of this technique. In order to reduce the range of possible solutions, we have analyzed how the values of model parameters changes as a function of the number of factors. PMF modeling was performed in a robust mode. For the purpose of finding the best fit solution wich minimize the object function Q, we varied the number of factors in the range from 4 to 8. Additionally, influence of rotations are also analyzed in iterative steps by varying FPEAK function in the range -1 to +1 with an increment of 0.5. Obtained results indicated significant role of Q/Qexp ratio analysis for optimal solution choice. In optimization process, number of factors with Q/Qexp ratio less than 1, were rejected as a possible solutions. This paper shows that optimization procedure should include examination of rotational matrix in which the rotational degree of freedom of solution is considered. Solutions with a steep change in their rotational degree of freedom were rejected. Finally, the additional improvement can be done by optimizing the parameters representing the scaled mean value (IM) and the scaled standard deviation (IS) of the each individual column in scaled residual matrix.

AB  - A significant proportion of homes and apartments in Serbia are still reliant on central heating systems during winter months, with about fifty heating plants in operation. Common fuels used in these plants primarily include fossil fuels such as coal, fuel oil, and natural gas. Some of these fuels have a high sulfur content, leading to an increased concentration of sulfur dioxide and particulate matter in the atmosphere (Todorović et al, 2020; Todorović et al, 2021). This study compares and evaluates the environmental impact of the two heating boilers at the Valjevo city (Serbia) heating plant. The AERMOD air dispersion model was used for estimating the concentrations of the various pollutants (Kakosimos et al, 2011; Mokhtar et al, 2014; Shaikh et al, 2020). Onsite emission data were gathered separately for the two heating boilers at the facility fuelled by natural gas and fuel oil, respectively. A combination of topographical and historical meteorological data were used to set up a receptor grid that was exposed to the gas emission in a radius of 10 km. The environmental impact from the fuel oil boiler was shown to be significantly higher than that caused by the natural gas-fuelled boiler. The resulting distribution of pollutant gases and particles showed that the concentration gradient is less inclined towards the city centre and instead spreads eastwards into the surrounding villages. The data were used to evaluate carcinogenic and non-carcinogenic health risks. It was found that the health risk was acceptable for different averaging periods. However, further study is still required in order to properly assess the cumulative health risk generated by other surrounding industries.

abstract = "A significant proportion of homes and apartments in Serbia are still reliant on central heating systems during winter months, with about fifty heating plants in operation. Common fuels used in these plants primarily include fossil fuels such as coal, fuel oil, and natural gas. Some of these fuels have a high sulfur content, leading to an increased concentration of sulfur dioxide and particulate matter in the atmosphere (Todorović et al, 2020; Todorović et al, 2021). This study compares and evaluates the environmental impact of the two heating boilers at the Valjevo city (Serbia) heating plant. The AERMOD air dispersion model was used for estimating the concentrations of the various pollutants (Kakosimos et al, 2011; Mokhtar et al, 2014; Shaikh et al, 2020). Onsite emission data were gathered separately for the two heating boilers at the facility fuelled by natural gas and fuel oil, respectively. A combination of topographical and historical meteorological data were used to set up a receptor grid that was exposed to the gas emission in a radius of 10 km. The environmental impact from the fuel oil boiler was shown to be significantly higher than that caused by the natural gas-fuelled boiler. The resulting distribution of pollutant gases and particles showed that the concentration gradient is less inclined towards the city centre and instead spreads eastwards into the surrounding villages. The data were used to evaluate carcinogenic and non-carcinogenic health risks. It was found that the health risk was acceptable for different averaging periods. However, further study is still required in order to properly assess the cumulative health risk generated by other surrounding industries.",

AB  - Adverse health effects of ionizing radiation raise a concern related to the inhalable radionuclides in the ambient air, but the additional risk comes from the coarse, fine and ultrafine atmospheric particulate matter with complex predominantly non-radioactive trace elements. Assessment of these two pollutant categories usually includes different approaches and research methodologies although both obey to similar processes and influences in the atmospheric environment. Physical-chemical characteristics and correlations of Pb-210, Be-7 and Cs-137 activity concentrations in total suspended particles and selected trace elements concentrations in the fine fraction (PM2.5) of atmospheric particulate matter, observed at the suburban monitoring station have been a subject of this study. Radionuclides data, reported in the national annual radioactivity monitoring reports, had been obtained by gamma spectrometry analysis (HPGe) of monthly composite samples, collected on daily basis, using cellulose filters and high-volume sampler (air flow about 50m3/h). Fine particulate aerosol fraction within our research had been sampled by European reference low-volume sampler (2.3 m3/h) with nozzles passing the particles with aerodynamic diameter less than 2.5 µm onto preconditioned PTFE filters. In this case daily aerosol samples were analyzed by non-destructive nuclear analytical technique to obtain simultaneously concentrations of trace elements. The statistics of radionuclides and trace elements concentrations was done and correlations and mid-term trends have been analyzed and discussed based on the knowledge on the radionuclides origin in the atmosphere, nuclear data, meteorological and precipitation data at the sampling site. Results have shown various correlations between the cosmogenic Be-7 and naturally occurring Pb-210 (Rn-222 descendant, from U-238 radioactive series) with Al, Si, Fe, Pb, Ca, elements pointed as tracers of soil-related factor in source apportionment receptor analysis (EPA PMF). Although the observed correlations and meteorological parameters have shown a dominantly natural origin of these elements, the industrial emissions might still contribute in some extent. Differences between elemental lead and radionuclide Pb-210 concentration allow us to distinguish shares coming from local soil and from the antropogenic activities in the investigated environments. This study has shown a capacity of naturally occurring radionuclides to be the tracers of processes in lower layers of atmosphere or the indicators of pollution origin, especially in boundary urban areas.

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  - The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/ cement ratio, the amount of waste, and the porosity of such a structure. Implementing the standard leaching method by Hespe the possibility of comparing different authors’ results was achieved. Diffusion and semi-empirical model were used to investigate the transport phenomenon in order to predict the leaching level for a long period of time. Leaching of Co2+ and Cs+ ions under dynamic conditions immobilized in the cement matrix dynamic conditions decreases with the increase of the sludge content, regarding porosity increase. The effects of the diffusion and surface washing are equalized, and the contribution ofthe matrix dissolution to the Cs + and Co2+ transport in the cement porous media increases, on average, for one order of magnitude. The semi-empirical model gives a better approximation for Co2+ and Cs+ leaching process for the duration ofthe experiment while both models significantly approximate leaching results in dynamic conditions. © 2019, Vinca Inst Nuclear Sci.

abstract = "The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/ cement ratio, the amount of waste, and the porosity of such a structure. Implementing the standard leaching method by Hespe the possibility of comparing different authors’ results was achieved. Diffusion and semi-empirical model were used to investigate the transport phenomenon in order to predict the leaching level for a long period of time. Leaching of Co2+ and Cs+ ions under dynamic conditions immobilized in the cement matrix dynamic conditions decreases with the increase of the sludge content, regarding porosity increase. The effects of the diffusion and surface washing are equalized, and the contribution ofthe matrix dissolution to the Cs + and Co2+ transport in the cement porous media increases, on average, for one order of magnitude. The semi-empirical model gives a better approximation for Co2+ and Cs+ leaching process for the duration ofthe experiment while both models significantly approximate leaching results in dynamic conditions. © 2019, Vinca Inst Nuclear Sci.

AB  - In 2018, Laboratory for Environment and Radiation Protection took part in the proficiency test "REM 2018 radon-in-water proficiency test". The task of this proficiency test was to determine the concentration of radon in the water sample. This sample  was  measured  by  gamma  spectrometry  on  HPGe  detector.  Firstly,  the measurement was performed on the native sample, without opening the bottle in which the sample was delivered. After that, the sample was placed into Marinelli beaker and measured again on the same detector. To calculate the activity concentration of radon in the  sample,  the  calibration  was  performed  using QA/QC  sample  from  the IAEA-TEL-2018-03 proficiency test andthe efficiency transfer was performed using EFFTRAN software. Comparison of the obtained results with the reference value, provided in the preliminary report of the proficiency test, showed that there is a significant influence of the measurement geometry and the calculation approach. In thispaper, the results of both approaches to the measurement and calculation will be presented and the trueness and precision of the results will be analyzed and commented.

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  - Merna nesigurnost rezultata merenja predstavlja pokazatelj kvaliteta izvršenog merenja. U laboratorijama za ispitivanje najčešće se prikazuje kombinovana merna nesigurnost na nivou poverenja 95% (k=2). U slučaju kada laboratorijskoj analizi prethodi postupak uzorkovanja, budžet nesigurnosti rezultata merenjatreba (prema ISO17025:2017), da obuhvata i nesigurnost koja potiče usled postupka uzorkovanja. U ovom radu je opisan postupak procene nesigurnosti rezultata merenja usled uzorkovanja.
AB  - The uncertainty of the measurement results is an indicator of the quality of the performed measurement. In the testing laboratories, the combined measurement uncertainty is usually given at the level of confidence of 95% (k = 2). If the laboratory analysis is preceded by a sampling procedure, the uncertainty budget of the measurement results should (according to ISO17025: 2017) include the uncertainty arising from the sampling procedure.

U laboratorijama za ispitivanje najčešće se prikazuje kombinovana merna nesigurnost na nivou poverenja 95% (k=2). U slučaju kada laboratorijskoj analizi prethodi postupak uzorkovanja, budžet nesigurnosti rezultata merenjatreba (prema ISO17025:2017), da obuhvata i nesigurnost koja potiče usled postupka uzorkovanja. U ovom radu je opisan postupak procene nesigurnosti rezultata merenja usled uzorkovanja., The uncertainty of the measurement results is an indicator of the quality of the performed measurement. In the testing laboratories, the combined measurement uncertainty is usually given at the level of confidence of 95% (k = 2). If the laboratory analysis is preceded by a sampling procedure, the uncertainty budget of the measurement results should (according to ISO17025: 2017) include the uncertainty arising from the sampling procedure. This paper describes the procedure for estimating the uncertainty of the results of measurement due to sampling.",

AB  - During the construction of nuclear facilities, radiotherapy centers, hospitals with radiological diagnostic facilities, and radioactive waste storage facilities, complex requirements for protection against ionizing radiation have been set up. In its basic principles, modern approaches in the design of radiation protection procedures were derived from empirical conclusions that were obtained by solving practical problems encountered by nuclear engineers and physicists. In the radiation protection projections, as well as in the formation of different technical and technological procedures in the radiation environment, one of the most important characteristics is the build-up factor of the material used. Based on experimental and theoretical research, empirical formulas for calculating the build-up factors are used to solve practical problems in radiation protection. With the development of information and computer technologies for calculating the build-up factor, other numerical methods are also used, of which a very attractive and efficient Monte Carlo calculation method is used. In this paper, the calculations with the empirical approximate formulas by Taylor and Berger, as well as the results obtained by using the software based on the Monte Carlo method, were used to determine the build-up of the factors in the protection of gamma and X radiation for several selected materials (lead, water, iron, etc.). By comparing the results obtained with the empirical approximations and Monte Carlo calculations, certain conclusions have been drawn that direct us to new critical considerations about the usefulness of using the chosen method of calculation for the build-up factor of materials found in modern technological processes using sources of gamma and X radiation.

The  following  radiological parameters are presented in this study: soil-crop transfer factor, nuber of strontium units, discrimination  coefficient  and K-parameter.  These  parameters  are  calculated  based  on the specific activity of 90Sr and total Ca concentration in soil and crop. The results of the parameter calculation indicated that for the most part, 90Sr is acumulated in the root of the  crop,  which  confirmes  that  the  main  path  of  the  acumulation  is  the  resuspension from  soil; 90Sr  acumulation  rate,  in  comparison  to  total  Ca  in  soil,  depends  on  the  soil and crop type as well as the total Ca concentration in soil.

AB  - Berilijum-7 (7Be)je radioaktivni berilijumov izotop koji nastaje u interakcijama kosmič-kog zračenja sa atomima atmosfere. Intenzitet kosmičkog zračenja usled nehomogenosti magnetnog polja Zemlje, ispoljava prostornu distribuciju, dok je vremenska distribucija posledica vremenski promenljivog magnetnog polja Sunca. Cilj ovog istraţivanja je da se  izvrši  analiza  uticaja  vremenske  promene  intenziteta  kosmičkog  zračenja  na koncentraciju7Be  u  kompozitnim  mesečnim  uzorcima  ukupnog  (suvog  i  mokrog) depozita. Uzorci depozita su sakupljani u Institutu za nuklearne nauke "Vinča", a sva merenja  koncentracije 7Be su uraĎena u Laboratoriji za zaštitu od zračenja i zaštitu ţivotne sredine. Rezultati merenja uzoraka prikupljenih u periodu od 1994. do 2016. su korelirani sa mesečnim podacima o intenzitetu kosmičkog zračenja iz istog perioda, preuzetim  sa  sajta  stanice "Apatity", Polarnog geofizičkog instituta, Ruske akademije nauka.  Ova  stanica  poseduje  neutronski  monitor  "Standard  18-NM-64"  lociran  na nadmorskoj  visini  od  181  m  sa  geografskim  koordinatama  od  N:67,57°  i  E:33,39°. TakoĎe, rezultati merenja oba posmatrana parametra su grupisani po godinama i mese-cima u godini, a zatim su odreĎeni njihovi godišnji i mesečni indeksi. Nakon toga, za ispitane  parametre  su  meĎusobno  korelirani  kako  godišnji,  tako  i  njihovi  mesečni indeksi. Dobijeni rezultati ukazuju da fluktuacije kosmičkog zračenja utiču samo na varijacije  godišnjih  indeksa  koncentracije7Be   u   ukupnom   depozitu.   Koeficijent determinacije godišnjih indeksa posmatranih parametara govori da se modulisanošću kosmičkog zračenja moţe objasniti 33% varijacije godišnjih vrednosti koncentracije 7Be u depozitu.
AB  - Beryllium-7 (7Be) is a radioactive beryllium isotope that is produced in the interaction of cosmic radiation with atmospheric atoms. Due to the heterogenous of the Earth's magnetic  field,  the  intensity  of  cosmic  radiation  exhibits  spatial  distribution,  while  the time  distribution  is  a  consequence  of  the  time-varying  magnetic  field  of  the  Sun.  The aim  of thisresearch  is  to  analyzethe  influence  of  the  intensity  of  cosmic  radiation  on the 7Be concentration in samples of the total (dry and wet) deposit. The deposit samples were  collected  at  the  Vinţa  Institute  of  Nuclear  Sciences,  and  all 7Be  concentration measurements  were  performedin  the  Department  of  Radiation  and  Environmental Protection.  The  results  of  the  measurements  were  collected  in  the  period  from  1994  to 2016 and they were correlated with the monthly neutron monitor data of the "Apatity",the Polar Geophysical Institute, the Russian Academy of Sciences. This station has the neutron  monitor  "Standard  18-NM-64"  located  at  the  altitude  of  181  m  with  geogra-phical coordinates of N:  67.57° and E: 33.39°. Also, the results of the measurement of both  observed  parameters  are  grouped  by  years  and  months  of  the  year,  and  then  their annual and monthly indices were determined. After that, the annual as well as monthly indices  of  the  observed  parameters  were  correlated.  The  obtained  results  indicate  that the fluctuations in the galactic part of cosmic radiation affect the variation of the annual 7Be  concentration  index  in  the  deposit.  The  coefficient  of  determining  the  annual indices  of  the  observed  parameters  shows  that  the  modulation  of  cosmic  radiation  can explain  33%  of  the  variation of  the  annual  values of the concentration of 7Be in the deposit.
