AB  - Jedan od značajnih načina kontrole rada termoelektrana (TE) na ugalj je kontinuirano praćenje vrednosti koncentracija aktivnosti radionuklida prirodnog porekla sadržanih prvenstveno u uglju, a potom i uzorcima pepela i šljake kao glavnim produkatima sagorevanja uglja koje je zbog svoje obilne proizvodnje neophodno odlagati na deponije otpada. Koncentracije aktivnosti prirodnih radionuklida 238U, 235U, 226Ra, 210Pb, 232Th i 40K, koje bi u životnoj sredini potencijalno mogle biti preraspodeljene kao posledica rada TE, podležu redovnoj kontroli u uzorcima uglja, šljake, elektrofilterskog pepela, kao i u uzorcima sakupljenim sa deponija pepela, na aktivnoj i pasivnoj kaseti, i zemljištu uzorkovanom na manjoj i većoj udaljenosti od TE. Predmet ovoga rada je analiza rezultata višegodišnjih merenja obavljenih u periodu od 2010. do 2022. godine. Godišnje vrednosti koncentracija aktivnosti izmerene za svaki ispitivani radionuklid i svaku od sedam vrsta uzoraka posmatrane su kao hronološki nizovi podataka koji čine diskretne vremenske serije za koje su rezultati statističke analize ukazivali da se mogu opisati kao procesi tzv. belog šuma.
AB  - One of the most important means of controlling the operation of coal-fired power plant (CFPP) is the continuous monitoring of naturally occurring activity concentrations of radionuclides contained primarily in coal and, consequently, in ash and slag samples, the main coal combustion products that must be disposed of in landfills due to their high production. The activity concentrations of the naturally occurring radionuclides 238U, 235U, 226Ra, 210Pb, 232Th, and 40K, which could potentially be released into the environment as a result of the CFPP operation, are regularly monitored in the samples of coal, slag, and fly ash, as well as in the samples of ash piles on the active and passive cassettes and in the soil sampled at lesser and greater distances from the CFPP. The aim of this work is to analyse the results of the multi-year activity concentration measurements carried out in the period from 2010 to 2022. The annual activity concentration values measured for each studied radionuclide and each of the seven sample types were observed as a chronological sequence of data forming discrete time series, which, according to the results of statistical analysis, may be described as white noise processes.

AB  - In accordance with ISO/IEC 17025:2017, the testing laboratory needs to verify its ability to properly perform methods. For radiological testing, the sampling does not affect the results directly, but it has to ensure that sample adequately represents the tested material. To verify the procedure, a sampling of red mud and bauxite ore was conducted. All samples were measured in identical geometry by HPGe spectrometer. The counting rates per unit mass in the recorded spectra were compared. For each measurement series, the mean and standard deviations of respected peaks were calculated, as well as average and standard deviation of all series. The obtained results of each individual series were considered satisfactory, i.e. sampling procedure ensures the representativeness of the bulk material, if it is within ± two standard deviations of the average of the mean values.

AB  - The operation of coal fired power plants greatly influences the surrounding environment, especially water and soil, due to large amounts of combustion waste products released. Besides the quality of soil and water from the aspect of chemical and structural composition (release of heavy metals, ash and slag deposition on soil) it is of at most importance to maintain a strict control from the radiological safety point of view. All coal types contain certain amount of naturally occurring radionuclides, which depends on the composition of the rock and soil adjacent to the place of the coal excavation. These radionuclides are concentrated in the process of coal combustion, thus leading to potentially high levels of radioactivity in the ash and slag. These by – products are released into the environment and can increase the radiation burden on the environment, change the composition of the soil and bodies of water in the vicinity, thus potentially influencing the health of the general population. In this paper, the radiological analysis of soil and water samples taken from the vicinity of different coal fired power plants in Serbia in the period of 2019-2021. will be presented. Measurements are performed in the Radiation and Environmental Protection Department of Institute of Nuclear Sciences Vinča within the framework of regular environment monitoring of the power plants.

AB  - Radiostrontium is released to the environment during the testing and use of nuclear weapons mainly in the fifties and sixties of XX century, in addition to nuclear power plant accidents (to some extent in 1986 owing to the Chernobyl accident) and the nuclear fuel reprocessing industry. Strontium is a chemical analogue of calcium (both are earth-alkaline metals) and accordingly when entering a human or animal body, it behaves similar to calcium. A large portion of the strontium will accumulate in bone and teeth and then is included in the metabolism along with Ca, and like calcium, it transfers to milk. Since the strontium uptake by the human body from milk is an important pathway for radiostrontium incorporation, milk and dairy products are good indicators of strontium-90 (Sr-90) content in human diet. Based on the mentioned, the knowledge about Sr-90 content in milk and dairy products is of extreme importance to prevent and control contamination of the food chain. The present study was conducted in order to radiologically control for Sr-90 content in raw milk and some dairy products samples composed of representative locally purchased milk. The analyses are performed using radiochemical analytical oxalate precipitation method, whereby interfering radionuclides are removed by precipitation scavenging. Yttrium-90 (Y-90) is generated from the beta decay of Sr-90. After the ingrowth Y-90 is separated and equilibrium is established, the samples are measured by gas flow proportional counter. The results of investigation showed that Sr-90 activity concentration in many investigated samples was at a lower level than minimum detectable activity (MDA) of the method.

abstract = "Radiostrontium is released to the environment during the testing and use of nuclear weapons mainly in the fifties and sixties of XX century, in addition to nuclear power plant accidents (to some extent in 1986 owing to the Chernobyl accident) and the nuclear fuel reprocessing industry. Strontium is a chemical analogue of calcium (both are earth-alkaline metals) and accordingly when entering a human or animal body, it behaves similar to calcium. A large portion of the strontium will accumulate in bone and teeth and then is included in the metabolism along with Ca, and like calcium, it transfers to milk. Since the strontium uptake by the human body from milk is an important pathway for radiostrontium incorporation, milk and dairy products are good indicators of strontium-90 (Sr-90) content in human diet. Based on the mentioned, the knowledge about Sr-90 content in milk and dairy products is of extreme importance to prevent and control contamination of the food chain. The present study was conducted in order to radiologically control for Sr-90 content in raw milk and some dairy products samples composed of representative locally purchased milk. The analyses are performed using radiochemical analytical oxalate precipitation method, whereby interfering radionuclides are removed by precipitation scavenging. Yttrium-90 (Y-90) is generated from the beta decay of Sr-90. After the ingrowth Y-90 is separated and equilibrium is established, the samples are measured by gas flow proportional counter. The results of investigation showed that Sr-90 activity concentration in many investigated samples was at a lower level than minimum detectable activity (MDA) of the method.",

AB  - In accordance with ISO/IEC 17025:2017 - General requirements for the competence of testing and calibration laboratories, the laboratory needs to verify its ability to properly perform methods before introducing them, by ensuring it can achieve the required performance (article 7.2.1.5). Also, if a laboratory carries out a sampling of a material, it needs to have a sampling plan and method established (article 7.3.1). In laboratories dealing with radionuclide content testing, the sampling does not affect the testing results directly, but the sampling procedure has to ensure that the taken and later measured sample adequately represents the tested material. In order to verify the sampling procedure for the needs of radiological tests, a sampling of red mud (13 samples) and bauxite ore (6 samples) was conducted in the aluminum factory “Alumina ltd”, Zvornik, Bosnia and Herzegovina in June 2021. In accordance with the established sampling procedure, GPS coordinate and ambient dose rate were recorded for each sample. Samples were prepared in accordance with IAEA, TRS 295 (1989), placed into identical PVC cylindrical boxes and measured by HPGe gamma spectrometer. Spectra of bauxite and red mud were recorded in 10 consecutive measurements for 21000 s and 6000 s, respectively, in order to achieve good statistic. For the purpose of sampling procedure verification, the counting rates per unit mass in the recorded spectra were compared. For each measurements series, the total counts in the spectrum as well as individual energies mean value and standard deviations were calculated. After the measurements were completed, the average of the each individual series mean values and the associated/corresponding standard deviation were calculated. The measurement result of each individual series is considered satisfactory if, taking into account the calculated standard deviation, it is within +/- two standard deviations of the average of the mean values. The obtained results verified the sampling procedure, i.e. it was shown that the applied sampling procedure ensures the representativeness of the bulk material

Due to this and due to the nature of the measurement itself, quality control of these instruments is readily performed, at least 2 times per year. The control is performed using a 60Co closed point source with the original protective lead casing and an absorber placed over it in order to mimic the real measurement dose levels. Mean value of the ratio of the first 10 consecutive measurements and the activity of the source on the day of the measurement is declared as a baseline value, while the standard deviation of these 10 values was used to establish the limits of acceptance.

AB  - Thermal power plants, as potential pollutants that have a great impact on the environment, have, among other things, the obligation to conduct regular control of radioactivity in the living and working environment. Radionuclides that are naturally present in coal used to produce electricity are concentrated in combustion products (ash, slag, wastewater, etc.). As these products are disposed of in the environment, it is necessary to regularly perform measurements to control the presence of natural radionuclides in samples from the environment near thermal power plants. This paper will present the results of testing the content of natural radionuclides in the soil sampled at several locations in the vicinity of TPP "Nikola Tesla" A and TPP "Kolubara" in the period from 2016-2020 years. The measurements were performed in the Laboratory for Radiation Protection and Environmental Protection of the Vinca Institute of Nuclear Sciences, using the standard gamma spectrometry method after adequate sample preparation. The sampling locations were selected to cover the immediate surroundings of the thermal power plant, where the possible impact of the thermal power plant operation would be most noticeable. Also, sampling was performed at locations that are far from the thermal power plant itself, most often in populated areas, in order to ensure knowledge of the local natural level of radionuclide content in the soil. The measured concentrations of natural radionuclide activity in the soil were monitored over a number of years and a comparison was made between samples taken nearby and those taken away from the thermal power plant, as well as soil samples from other parts of Serbia and literature data. In that way, optimal monitoring of the impact of the thermal power plant operation on the environment is provided.

AB  - Tritium concentrations in water samples were analyzed. The aim is to compare methods: standard method (direct method): according to ASTM D 4107-08 and validated method: which applies electrolytic enrichment. Low level tritium concentration in natural waters required measurement after enrichment. One set of samples, which contain 16 samples including spike water were enrichment and compared with 4 samples measured by direct method. For this analysis liquid scintillation spectrometer was using. In general, analysis with enrichment is more applicable for samples with low activity. Also, validated method with enrichment reduced minimum detectable concentration.

AB  - Gamma spectrometry is widely used method of choice for measurement of environmental samples conducted during monitoring of the environment and contamination control, as well as measurement of radionuclide content in various materials. However, one of the main challenges in this method of spectrometry is the determination of detection efficiency for different energies, different source-detector geometries and different composition of samples. This task is defined as an efficiency calibration of the detector. When using a commercial calibration sources is not possible, or the available sources are not adequate, the optimization of the efficiency calibration has to be performed. In this paper, the results of the optimization of efficiency calibration for the atypical geometry and composition of the simulated aerosol samples, measured within the Proficiency tests organized by International Atomic Energy Agency (IAEA), performed using EFFTRAN efficiency transfer software, will be presented and discussed.

AB  - Aerosol sampling and monitoring of naturally occurring and artificial radionuclides is readily performed within the frame of Environmental radioactivity monitoring in the Republic of Serbia. It provides information important for the preservation of the public health and the environment from the harmful effects of ionizing radiation. This type of monitoring has been performed in Institute of Nuclear Sciences Vinča for more than 30 years now. The radionuclides that are measured are: naturally occurring 210Pb, artificial radionuclide 137Cs and cosmogenic radionuclide 7 Be. Particle reactive radionuclides such as 210Pb and 7 Be have been used as atmospheric tracers for studying environmental processes such as cloud scavenging and precipitation [1], aerosol transit and residence times in the troposphere [2], and aerosol deposition velocities [3]. The fission product 137Cs is an indicator of anthropogenic pollution caused by nuclear weapon atmospheric tests and nuclear power plant accidents. Seasonal variation in 137Cs in air is an indicator of the stratosphere-troposphere exchange processes [4]. In most aerosol samples in later years, the activity concentration of 137Cs is below the minimal detectable activity and therefore it was not taken into the consideration in this paper. The activity concentration of 7 Be is dependent on the movements of large air masses and vertical mixing in the atmosphere and also was not discussed in this paper. In this paper, the activity concentration of 210Pb in aerosol samples, obtained over the period from 2014. to 2020., was discussed. Sampling is performed using constant air flow pumps and Whatman filter papers on 6 measuring stations distributed in various parts of the country. Three stations are in urban areas of cities of Belgrade, Vranje and Zaječar and other three are in rural areas (Palić and Zlatibor) or removed from the urban part of the city (Meteorological station in Vinča). The monthly composite sample from each sampling station was ashed at the temperature below 400o C. After ashing, the residue aerosol is measured on HPGe detectors using a standard gamma spectroscopy method [5]. The results for 210Pb are of the order of magnitude of 10-4 to 10-3 Bq/m3 . The activity concentration in all investigated samples shows temporal dependence with the maxima in the winter months and minima observed during the spring and summer. Also, the comparison between the results obtained from the rural and urban locations was performed in order to investigate the influence of the air pollution present in the urban areas on the activity concentration of 210Pb. The values, obtained at stations located in rural parts, ranged from (0.056 – 3.3) mBq/m3 , while for stations located in urban areas the range was from (0.125 – 2.9) mBq/m3 . It can be seen that from all the data that the activity concentration of 210Pb was lower in rural areas. Two outliers were observed at Palic station, located in the plane and along the path of the prevailing south – east wind, possibly bringing aerosols from Deliblatska pescara (Deliblato Sands) [6].

AB  - U ovom radu su predstavljeni rezultati merenja jačine ambijentalnog ekvivalenta doze gama zračenja, izvršenih u toku redovnog monitoringa TE „Kostolac“, koje sprovodi Laboratorija za zaštitu od zračenja i zaštitu životne okoline, Instituta za nuklearne nauke “Vinča“. Jačina ambijentalnog ekvivalenta doze je merena u vazduhu na 1m iznad tla na određenim tačkama unutar lokaliteta termoelektrane i na deponijama pepela i šljake, istovremeno sa uzorkovanjem na istim lokacijama, korišćenjem dozimetra sa scintilacionom sondom. Takođe, tokom godina u kojima je vršen monitoring, vršena su i kontinualna merenja ambijentalnog ekvivalenta doze na lokacijama u naseljima u okolini TE „Kostolac“, korišćenjem termoluminescentnih (TLD) dozimetara. Analiziranjem dobijenih vrednosti tokom dužeg perioda kontinualnog i pojedinačnih merenja, dolazi se do zaključka o uticaju rada termoelektrane na životnu i radnu okolinu.
AB  - This paper presents the results of measurements of the ambient dose equivalent rate of the gamma radiation performed within the regular monitoring of the coal-fired power plant „Kostolac“, performed by the Radiation and Environmental Protection Department of „Vinča“ Institute of Nuclear Sciences. Ambient dose equivalent rate is measured in the air, at 1 m height above the ground at defined sites within the territory of the power plant and the ash and slag disposal dumps, at the moment of sampling at these sites, using a dosimeter with a scintillation probe. Also, during the yearsin which the monitoring was performed, continuous measurements of the ambient dose equivalent on the location of settlements in the vicinity of the power plant were conducted, using termo luminescent dosimeters (TLD). The comparison of the long term measurements and measurements performed on the sampling sites, a conclusion about the influence of power plant on the living and working environment can be reached

AB  - U ovom radu su predstavljeni rezultati poređenja sadržaja prirodnih radionuklida u različitim uzorcima elektrofilterskog pepela, pepela sa deponija i šljake. Poređenje je izvršeno između rezultata dobijenih u redovnoj kontroli radioaktivnosti u radnoj i životnoj okolini TE „Kostolac“, TE „Kolubara“i TE „Nikola Tesla A“, koje sprovodi Laboratorija za zaštitu od zračenja i zaštitu životne okoline, Instituta za nuklearne nauke “Vinča“. Na osnovu merenja koncentracije prirodnih radionuklida u uzorcima elektrofilterskog pepela, pepela sa deponija i šljake, kao i na osnovu određenog odnosa između dobijenih vrednosti u uzorcima iz različitih termoelektrana, možemo da zaključimo da je ovaj otpadni materijal iz TE “Kostolac” izuzetno povoljan kao sirovina koja bi se koristila za proizvodnju građevinskog materijala i da daje približno dvostruko manji uticaj na gama indeks konačnog proizvoda u odnosu na otpadni material iz drugih termoelektrana.
AB  - This paper presents the results of the comparison between the naturally occurring radionuclide content in different samples of fly ash, ash and slag. The comparison was conducted between the results obtained within the regular control of radioactivity in working and living environment of TE „Kostolac“, TE „Kolubara“ and TE „Nikola Tesla A“, which is performed by the Radiation and Environmental Protection Department of „Vinča“ Institute of Nuclear Sciences. Based on the activity concentration measurement in samples of fly ash, ash from the ash disposal dumps and slag, as well as based on the calclulated ratio between the values obtained for different coal fired powerplants, it can be concluded that this waste material from TE “Kostolac” is promising material as an additive in building material production and that it gives approximately twice as low contribution to the gamma index as those obtained from other two powerplants.

AB  - Istraživanja obuhvaćena ovom studijom predstavljaju prikaz efekata svojstava tla različitih poljoprivrednih koncepata na migraciju antropogenih radionuklida, 90Sr i 137Cs. Za potrebe ovog rada, izvršeno je uzorkovanje obradivog zemljišta na dve dubine na teritoriji grada Beograda tokom 2014. godine. U uzorcima zemljišta su određene fizičko−hemijske osobine i specifične aktivnosti ispitanih radionuklida. Radiohemijska analitička metoda je primenjena za određivanje sadržaja 90Sr, dok je specifična aktivnost 137Cs određena primenom gamaspektrometrijske metode. Ispitivanje efekata svojstava analiziranih uzoraka obradivog zemljišta na migraciju 90Sr i 137Cs, izvršeno je statističkim metodama analize. Primenom linearne korelacione analize utvrđeni su dominantni fizičko−hemijski parametri koji utiču na migraciju 90Sr i 137Cs u poljoprivrednom zemljištu.
AB  - The research included by this study presents the effects of soil properties of different agricultural concepts to the migration of anthropogenic radionuclides, 90Sr and 137Cs. For the purposes of this paper, sampling of agricultural soil at two depths on the territory of the city of Belgrade during 2014 was performed. The physico−chemical properties of investigated soil, as well as the specific activities of the mentioned radionuclides were determined. The radiochemical analytical method was used to determine the 90Sr content, while the specific activity of 137Cs was determined using the gamma spectrometric method. Examination of the effects of soil properties on the migration of anthropogenic radionuclides 90Sr and 137Cs, based on the analyzed soil samples, was performed by statistical methods of analysis. By applying linear correlation analysis, the dominant physico−chemical parameters that affect the migration of 90Sr and 137Cs in agricultural soil were determined.

AB  - Rezultati merenja radioaktivnosti zemljišta, mulja i vode u procesu iskopavanja bunara do maksimalne dubine od 13,5 m u selu Poganovu, u opštini Dimitrovgrad, prikazani su u ovom radu. Uzorci mulja i zemljišta, analizirani su spektrometrijom gama emitera i određivanjem sadržaja 90Sr. U slučaju uzorka vode, određena je ukupna alfa i ukupna beta aktivnost, i koncentracija radionuklida gama emitera. Pored navedenih uzoraka, sa iste lokacije su mereni i uzorci mahovina i lišajeva. Osim u uzorku mahovine i zemljišta sa dubine 0-10 cm u kojima je detektovano prisustvo 137Cs u veoma niskim koncentracijama za ovu vrstu uzoraka, ni u jednom uzorku nije detektovano prisustvo proizvedenih radionuklida, 137Cs i 90Sr. U slučaju prirodnih radionuklida, dobijene vrednosti koncentracija, karakteristične su za ovakve vrste uzoraka i ne razlikuju se u odnosu na druge lokacije na našim prostorima. Svi rezultati merenja ukazuju na to da se ova lokacija može koristiti kao nulta tačka monitoringa radioaktivnosti na našim prostorima.
AB  - The results of radioactivity measurements in the soil, sludge and water samples in the process of finding water and digging wells to a maximum depth of 13.5 m, in the village of Poganovo, in the municipality of Dimitrovgrad, are presented in this paper. Sludge and soil samples were analyzed by gamma-ray spectrometry and 90Sr measurements. In the case of water samples, gross alpha and gross beta activity, as well as content of radionuclides gamma emitter were determined. In addition, samples of mosses and lichens from the same location were also measured. Presence of the artificial radionuclides 90Sr and 137Cs were not detected in measured samples, with an exception of the sample of moss and soil from a depth of 0-10 cm, where 137Cs was detected in very low concentrations for this type of samples. In the case of natural radionuclides, the obtained values of concentrations are characteristic of these types of samples and do not differ from other locations in our area. All measurement results indicate that this location can be used as a zero point for monitoring radioactivity in our area.

abstract = "Rezultati merenja radioaktivnosti zemljišta, mulja i vode u procesu iskopavanja bunara do maksimalne dubine od 13,5 m u selu Poganovu, u opštini Dimitrovgrad, prikazani su u ovom radu. Uzorci mulja i zemljišta, analizirani su spektrometrijom gama emitera i određivanjem sadržaja 90Sr. U slučaju uzorka vode, određena je ukupna alfa i ukupna beta aktivnost, i koncentracija radionuklida gama emitera. Pored navedenih uzoraka, sa iste lokacije su mereni i uzorci mahovina i lišajeva. Osim u uzorku mahovine i zemljišta sa dubine 0-10 cm u kojima je detektovano prisustvo 137Cs u veoma niskim koncentracijama za ovu vrstu uzoraka, ni u jednom uzorku nije detektovano prisustvo proizvedenih radionuklida, 137Cs i 90Sr. U slučaju prirodnih radionuklida, dobijene vrednosti koncentracija, karakteristične su za ovakve vrste uzoraka i ne razlikuju se u odnosu na druge lokacije na našim prostorima. Svi rezultati merenja ukazuju na to da se ova lokacija može koristiti kao nulta tačka monitoringa radioaktivnosti na našim prostorima., The results of radioactivity measurements in the soil, sludge and water samples in the process of finding water and digging wells to a maximum depth of 13.5 m, in the village of Poganovo, in the municipality of Dimitrovgrad, are presented in this paper. Sludge and soil samples were analyzed by gamma-ray spectrometry and 90Sr measurements.

AB  - According to the current legislation in the Republic of Serbia, the radiological control of waste materials is performed at border crossings, as well as when there is an intention to dispose these materials in the environment. The gamma ray spectrometry is commonly used for determination of radionuclide content in waste materials. These measurements imply adequate sample preparation in order to achieve the desired measurement geometry for which the efficiency of the gamma spectrometer has been calibrated. Satisfactory homogeneity is often not possible to achieve in the sample preparation process. Also, the matrix of the measured material in most cases does not correspond to the matrix of the standard used for efficiency calibration of the spectrometer. For these reasons, it is necessary to make certain corrections to the measurement results (efficiency transfer, for example), as well as to expand the measurement uncertainty budget. The paper presents in detail the procedure for assessing the contribution of inhomogeneity of the sample to the measurement uncertainty, as well as the contribution that the efficiency transfer and coincidence summing corrections introduce to the measurement uncertainty budget.

Activity concentrations of 40K, 137Cs, and 210Pb in different deciduous and evergreen trees in the region are investigated. For all the investigated isotopes, there is a tendency that, on average, the lowest activity concentrations were found in tree stems, then in leaves, while the highest ones were in the soil. Statistical analysis did not show any differences between activity concentrations of leaves and needles, showing that both leaves and needles could be equally well used as a biomonitors.
