AB  - Natural radionuclides are omnipresent in the environment. However, our environment is also contaminated with anthropogenic radionuclides that appear as a consequence of human activities. One of the main sources of increased radioactive contamination in environment was nuclear accident in Chernobyl in 1986. Medicinal herbs have long history of worldwide consumption in traditional medicine. Therefore, it is necessary to control the usage of medicinal herbs and their products, from radiological point of view, as well. In that way, unwanted radiological effects on human health can be avoided. The paper deals with radiological analysis of 7 selected medicinal herbs: (Thymus serpyllum L., Breckland thyme; Hypericum perforatum L., St. John's wort; Rosa canina L., Dog-rose; Mentha sp., mint; Melissa officinalis L., Lemon balm; Tilia tomentosa L., Silver Linden; Achillea millefolium, Yarrow) from the region of Fruška Gora, Republic of Serbia. Specific activities of 137Cs, 40K and 210Pb in medicinal herbs samples are determined by using HPGe gamma-ray spectrometer system. From obtained specific activities individual annual effective doses due to daily ingestion of 200 ml infusion of medicinal herbs were deduced. Obtained specific activities are in intervals: <1.4 Bq/kg, (303 – 1073) Bq/kg and (3.58 – 35.6) Bq/kg, for137Cs, 40K and 210Pb, respectively. Deduced individual annual effective doses due to ingestion are similar to the literature data and are smaller than the recommended limit of 100 μSv, defined in Article 8 of the Regulation on limits of radionuclide content in drinking water, foodstuffs, feeding stuffs, drugs, items of general use, building materials and other goods to be placed on the market (Official Gazette of the Republic of Serbia, 2018). Therefore, a daily use of 200 mL of herbal infusion during a year made from the investigated medicinal herbs does not pose a significant radiological health risk for consumers.

AB  - Ugalj kao fosilno gorivo sadrži brojne prirodne radioaktivne izotope koji pripadaju uranovom i torijumovom nizu, kao i 40K. Najviše se koristi u industriji, kao i u proizvodnji energije. Problem u vezi sa proizvodnjom energije iz uglja je takozvani „energetski otpad“, kao što su pepeo i šljaka, koji predstavljaju nesagorivi i nesagoreli ostatak pri sagorevanja uglja.

Da bi se utvrdio potencijalni uticaj „energetskog otpada“ na životnu sredinu, uzorci uglja, pepela i šljake iz termoelektrana „Nikola Tesla“ i „Kolubara“ mereni su poluprovodničkim HPGe spektrometrom u Laboratoriji za nuklearnu i plazmu fiziku Instituta „Vinča“. Kao rezultat ovih merenja, dobijene su koncentracije prirodnih radionuklida i veštačkog radionuklida 137Cs kao, što je prikazano u ranije objavljenim radovima. Prikazani rezultati su u saglasnosti sa istraživanjima sprovedenim širom sveta.   Da bi se obezbedila tačnost i preciznost (pouzdanost) dobijenih rezultata merenja, u okviru Laboratorije uspostavljen je program kontrole kvaliteta (QC) i osiguranja kvaliteta (QA). Interna kontrola obuhvata proveru karakteristika poluprovodničkog HPGe spektrometra koji se koristi za merenje svih analiziranih uzoraka. Tačkasti izvori 60Co i 137Cs se koriste kao kontrolni izvori za proveru položaja pika, ukupne površine ispod pika, FWHM (puna širina na polovini maksimuma pika), FWTM (puna širina na desetini maksimuma pika) i odnos FWHM/FWTM. Pored navedenih karakteristika, redovno se kontroliše i ukupni odbroj prirodnog fona. Svaka od navedenih karakteristika može ukazati na neku nepravilnost u radu detektorskog sistema.

The problems associated with the production of energy from coal is the so-called “energy waste”, such as ash and slag, which are incombustible and unburnt residue from combustion of coal. If ash and slag are released into the environment an increase and/or redistribution of natural radio-nuclide content can occur. To determine the potential impact of “energy waste” on the environment, samples of coal, ash, and slag from thermal power plant "Nikola Tesla" and "Kolubara" were meas-ured with a semiconductor HPGe spectrometer. Results of activity concentration of natural radionu-clides and artificial 137Cs in coal, slag and ash are presented in few previously published papers and obtained values are in accordance with similar worldwide investigations. o ensure the accuracy and precision (reliability) ofthe obtained measurement results, quality control (QC) and quality assurance (QA) program were established. Internal control includes check-ing of the characteristics of HPGe spectrometer used for measurement of all analysed samples. Point sources of 60Co and 137Cs are used as control sources for checking following characteristics: peak positions, net peak area, FWHMs (Full Width at Half Maximum), FWTMs (Full Width at Tenth Max-imum) and FWHM/FWTM ratios. In addition to the mentioned characteristics, the counting of back-ground is also regularly controlled. Each of the mentioned characteristics may indicate some irreg-ularity in the operation of the detector system and thus could influence reliability of performed activ-ity concentration measurements.The paper presents the control charts of the examined characteristics of the HPGe spectrometer used for measurements of coal, ash and slag samples. The obtained control charts indicate the long-term stability of the spectrometer and hence confirm accuracy and precision of measurement results.

AB  - Fourteen samples of nine different species were collected in the region of Fruška gora, the suburban areas of Belgrade, and the vicinity of Vlasina Lake (Serbia) have been analyzed from the radiological point of view. Specific activities of radionuclides 210Pb, 137Cs, and 40K were measured using a semiconductor HPGe spectrometer system in these wild mushroom samples. The activity concentrations of all measured dried wild mushrooms are for 210Pb: between 2.05 Bq/kg and 9.74 Bq/kg; for 137Cs: between < 0.2 Bq/kg and 19.3 Bq/kg; for 40K between 704 Bq/kg and 2530 Bq/kg. The total individual annual effective doses due to ingestion of 210Pb, 137Cs, and 40K radionuclides within a 0.5 kg dry mass of the wild mushrooms is between 3.99 µSv and 10.81 µSv, and are much lower than the recommended level for the public (1 mSv/y).

AB  - U bogatoj flori Srbije uspeva veliki broj vrsta lekovitog bilja čiji se sastojci koriste u farmaceutskoj industriji i medicini, kako zvaničnoj tako i narodnoj. Pored toga lekovito bilje se u velikoj meri koristi u svakodnevnoj upotrebi kao neka vrsta napitka. Prirodni radionuklidi (radionuklidi uranovog i torijumovog niza kao i K-40) sastavni su deo naše životne sredine, a kao posledicu nuklearnih akcidenata imamo i prisustvo antropogenih radionuklida, pre svega Cs-137. Masovna upotreba lekovitog bilja predstavlja radijaciono opterećenje za široku populaciju, pa je zbog toga neophodan redovan monitoring. U ovom radu analizirano je 9 vrsta lekovitog bilja sa područja Gučeva (Zapadna Srbija). Specifične aktivnosti prirodnih radionuklida Pb-210 i K-40, kao i Cs-137 određene su merenjem svih uzoraka na poluprovodničkom HPGe spektrometru. Izračunate su godišnje efektivne doze usled ingestije za svaki izmereni radionuklid, i za dve starosne kategorije (uzrast od jedne godine i odrasla osoba). Svi proračuni su zasnovani na pretpostavci da se dnevno pije 200 ml čaja priprepremljenog korišćenjem određene lekovite biljake. Dobijene vrednosti za efektivnu dozu ingestije upućuju na zaključak da svakodnevna upotreba čajeva od lekovitih biljaka sa analiziranog područja ne predstavlja značajan radiološki rizik po zdravlje odrasle osobe, ali je neophodan oprez i obazrivost kada su u pitanju deca.

Natural radionuclides (radionuclides of the uranium and thorium series as well as K-40) are an integral part of our environment, and as a consequence of nuclear accidents we also have the presence of anthropogenic radionuclides, primarily Cs-137. The significant use of medicinal plants represent a radiological burden for the general population, so the regular monitoring is needed. In this work, 9 types of medicinal plants from the area of Gučevo (Western Serbia) were analysed. The specific activities of natural radionuclides 210-Pb i 40-K as well as Cs-137 were determined using a semiconductor HPGe spectrometer. Annual effective dose due to ingestion were calculated for each measured radionuclide, and for two age categories (one year old and adult). All calculations are based on the assumption daily consumption of 200 ml of herbal tea. The obtained values for the annual effective dose due to ingestion point to the conclusion that the daily use of medicinal plant teas from the analyzed area does not represent a significant radiological risk for the health of adults, but caution and prudence are necessary when it is about children.

abstract = "U bogatoj flori Srbije uspeva veliki broj vrsta lekovitog bilja čiji se sastojci koriste u farmaceutskoj industriji i medicini, kako zvaničnoj tako i narodnoj. Pored toga lekovito bilje se u velikoj meri koristi u svakodnevnoj upotrebi kao neka vrsta napitka. Prirodni radionuklidi (radionuklidi uranovog i torijumovog niza kao i K-40) sastavni su deo naše životne sredine, a kao posledicu nuklearnih akcidenata imamo i prisustvo antropogenih radionuklida, pre svega Cs-137. Masovna upotreba lekovitog bilja predstavlja radijaciono opterećenje za široku populaciju, pa je zbog toga neophodan redovan monitoring. U ovom radu analizirano je 9 vrsta lekovitog bilja sa područja Gučeva (Zapadna Srbija). Specifične aktivnosti prirodnih radionuklida Pb-210 i K-40, kao i Cs-137 određene su merenjem svih uzoraka na poluprovodničkom HPGe spektrometru. Izračunate su godišnje efektivne doze usled ingestije za svaki izmereni radionuklid, i za dve starosne kategorije (uzrast od jedne godine i odrasla osoba). Svi proračuni su zasnovani na pretpostavci da se dnevno pije 200 ml čaja priprepremljenog korišćenjem određene lekovite biljake. Dobijene vrednosti za efektivnu dozu ingestije upućuju na zaključak da svakodnevna upotreba čajeva od lekovitih biljaka sa analiziranog područja ne predstavlja značajan radiološki rizik po zdravlje odrasle osobe, ali je neophodan oprez i obazrivost kada su u pitanju deca., In the rich flora of Serbia, there are a large number of medicinal plants types used in the pharmaceutical industry and medicine.

The paper presents the results of a three-and-a-half-year analysis of the gamma spectrometric system measurements in the Laboratory for Nuclear and Plasma Physics of the INN "Vinča". Measurements were made once a week and point sources Co-60 and Cs-137 were used as control sources. In addition to monitoring the count below the peak, the position of the peak, the full width at half maximum (FWHM), the full width at tenth maximum (FWTM), as well as their mutual ratio (FWTM/FWHM), the count in the background was also monitored. The results show that the gamma spectrometric system has satisfactory stability over a long period of time.

AB  - In order to compare alpha-particle and gamma-ray spectrometry, the activity concentrations of 235U, 238U and 226Ra in samples of coal, slag and fly-ash from the thermal power plant “Nikola Tesla A”, Serbia, were determined by these two methods. Methods were compared and discussed from the point of view of its precision, difficulty to apply and complexity. Gamma-ray spectrometry was performed with HPGe (High Purity Germanium) spectrometer, while alpha activity was measured by PIPS (Passivated Implanted Planar Silicon) detector. For the alpha-particle spectrometry, the chemical procedures applied were chromatographic resin extraction for uranium isotopes and micro-coprecipitation for 226Ra. Thin alpha sources were prepared by electrodeposition and filtration through polypropylene membrane filter for uranium determination, while filtration technique was performed for radium sources. For the evaluation of the statistical difference between individual measurement results obtained by application of two methods Z - test was used. In order to evaluate the difference between two methods used, paired samples t-test and F-test were applied. Results show that there is no statistical difference between two methods used and that gamma-ray spectrometry is a valid alternative to time consuming alpha spectrometry.

AB  - This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration of radionuclides and radon exhalation rate. The obtained radon mass exhalation rate ranges from (5.3 ± 3.1) mBqkg–1s–1 to (70.3 ± 9.4) mBqkg –1s–1 and was highest for lignite type of coal. It is estimated that coal stored in the basement could contribute up to 50 Bqm–3 of indoor radon concentration at the ground level. Activity concentrations of 226Ra, 232Th, 40K, 238U, 235U, and 210Pb in analysed coal samples agree with previously reported concentrations of coal used in Serbia. The values of radium equivalent concentration and external hazard index indicate that the used coal does not represent a significant radiation hazard.

AB  - Gamma ray spectrometry with high purity germanium (HPGe) detector is one of the most widely used methods for environmental samples measurements. It is basically a non-destructive method and usually there is no need for the extensive sample preparation. True coincidence summing effect has a significant effect in gamma ray spectrometry analysis, especially in low source-to-detector geometry. Many authors have paid attention to this problem mainly by analyzing and determining coincidence summing correction factors for artificial radionuclides. However, the effect of true coincidence summing can significantly affect the result obtained by gamma ray spectrometry of environmental samples. Therefore, special attention should be paid to the determination of correction factors for coincidence summing of radionuclides from natural series (uranium, thorium and actinium series). Coincidence summing correction factors can be determined in several manners. Application of appropriate software packages is one of the most common. Software packages EFFTRAN and GESPECOR are among the most used ones. These software are based on Monte Carlo simulation. EFFTRAN is efficiency transfer code with semiempirical approach, whereas GESPECOR is dedicated code specifically tailored to solve most of the problems concerning gamma spectrometric measurements. The values of the correction factors depend on the detector geometry as well as the relevant data related to analyzed sample. The geometry of the detector implies the parameters of the detector itself (crystal dimensions, thickness of the dead layer, the thickness of the detector window). On the other hand, the relevant data related to analyzed sample includes dimensions of the container in which the sample is packed, sample density, chemical composition. The aim of this work is to compare coincidence summing factors obtained by using EFFTRAN and GESPEOR software in the case of p-type semiconductor HPGe detector with 30 % relative efficiency. All coincidence summing correction factors were calculated for soil sample in the cylindrical geometry and for radionuclides which are usually analyzed for environmental samples: • for the uranium series: 214Pb for energies 295.22 keV and 351.93 keV; 214Bi for energies 609.32 keV, 1120.29 keV and 1764.54 keV;234mPa for energies 766.36 keV and 1001.03 keV. • for the thorium series: 212Pb for energies 238.63 keV and 300.09 keV; 208Tl for energy 583.19 keV; 212Bi for energy 727.33 keV; 228Ac for energies 911.2 keV and 968.97 keV. • for the actinium series: 235U for energies 143.76 keV, 163.33 keV, 185.71 keV and 205.31 keV. The obtained values of the correction factors for coincidence summing showed a good agreement between these two software packages. Mutual deviations between correction factors calculated by using EFFTRAN and GESPECOR software were within ± 3 %.

abstract = "Gamma ray spectrometry with high purity germanium (HPGe) detector is one of the most widely used methods for environmental samples measurements. It is basically a non-destructive method and usually there is no need for the extensive sample preparation. True coincidence summing effect has a significant effect in gamma ray spectrometry analysis, especially in low source-to-detector geometry. Many authors have paid attention to this problem mainly by analyzing and determining coincidence summing correction factors for artificial radionuclides. However, the effect of true coincidence summing can significantly affect the result obtained by gamma ray spectrometry of environmental samples. Therefore, special attention should be paid to the determination of correction factors for coincidence summing of radionuclides from natural series (uranium, thorium and actinium series).

AB  - Da bi se postigla tačnost i preciznost dobijenih rezultata pri gamaspektrometrijskom merenju uzoraka iz životne sredine neophodno je obezbediti odgovarajuće kalibracione standarde. Imajući u vidu da i sami standardi vremenom gube na kvalitetu zbog degradacije matriksa, od izuzetne je važnosti praćenje stabilnosti standarda koji se koriste. U ovom radu prikazani su rezultati ispitivanja karakteristika krivih efikasnosti u odnosu na starenje matriksa. Napravljeni su radni kalibracioni standardi sa tri različita matriksa (aktivni ugalj, zemlja i pesak), upakovani u cilindričnu geometriju kutijice od 120 ml i 250 ml i mereni na poluprovodničkom HPGe detektoru. Isti standardi ponovo su mereni nakon četiri godine u kontakt geometriji u odnosu na detektor i izvrnuto sa poklopcem kutijice ka detektoru. Analiza dobijenih rezultata pokazala je odstupanja u vrednostima efikasnosti, što ukazuje na degradaciju svih standarda u smislu narušavanja njihove homogenosti. Takvi standardi se ne mogu smatrati pouzdanim za korišćenje.
AB  - The gammaspectrometric measurement of the environmental samples requires the use of appropriate calibration standards in order to achieve the accuracy and precision of the obtained results. Taking into account that the standards lose their quality over time due to the degradation of the matrix, it is extremely important to keep tracking their stability. Comprehensive reconsideration on efficiency curves with respect to the ageing of calibration standards is presented in this paper. Spiked laboratory standards of different matrices (active coal, soil and sand) were prepared in two measurement geometries, PVC cylindrical 120 ml and 250 ml boxes. The same standards were measured after four years in contact geometry on the detector and upside down (box cover towards the detector). The analysis of the obtained results showed discrepancies in efficiency values and it indicates that the homogeneity of standards is disturbed. Such standards are not reliable for use.

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.
