AB  - Laboratorija za merenje radioaktivnosti Instituta za medicinu rada Srbije “Dr Dragomir Karajović” je prvobitnim merenjem koncentracije radona pomoću kanistera sa aktivnim ugljem, u privatnoj kući na Bežanijskoj Kosi u Beogradu, ustanovila povišenu koncentraciju u novom delu kuće. U cilju utvrđivanja razloga povišene koncentracije radona, nova merenja su organizovana u još tri navrata (etape), u različitim periodima, pokrivajući sva četiri godišnja doba. Rad predstavlja prikaz ovog slučaja u kom je pored pomenute laboratorije učestvovala i Laboratorija za nuklearnu i plazma fiziku Instituta “Vinča” uz kombinovanje većeg broja metoda: merenje koncentracije radona pomoću kanistera sa aktivnim ugljem, pomoću aktivnog uređaja – alfaspektrometra, određivanje koncentracije radona na osnovu ekshalacije radona iz poda prostorije i građjevinskog materijala, na osnovu merenja koncentracije radona u zemljištu, na osnovu gamaspektrometrijske analize zemljišta uzorkovanog iz dvorišta ispred kuće. Analizom dobijenih rezultata potvrđena su dosadašnja saznanja o dnevnim i sezonskim varijacijama koncentracije radona.
AB  - The Radioactivity Measurement Laboratory has initially measured the radon concentration, in a private house on Bežanijska Kosa in Belgrade, by activated charcoal canisters and established a high concentration in the new part of the house. In order to determine the reasons for the increased radon concentration, new measurements were organized three more times, in different periods, covering all four seasons. This paper presents a report of these measurements in which, the Nuclear And Plasma Physics Laboratory Of The "Vinca" Institute also participated with the combination of a larger number of methods: radon concentration measurement by activated charcoal canisters, radon concentration measurement by active device – alpha-spectrometer, determination of radon concentrations on the basis of radon exhalation rate from the floor of the room, from the building material, on the basis of the radon measurement from the soil, estimation of radon concentration on the basis of gamma spectrometry analysis of the soil sample, taken from the yard in front of the house. Analysis of the obtained results confirmed previous knowledge about seasonal and others variations in radon concentration.

AB  - In accordance with ISO/IC 17025:2017 testing laboratory shall have a procedure for monitoring the validity of results that includes regular participation in interlaboratory comparisons. Interlaboratory comparison RADON2021 was organized in the frame of the bilateral project between Serbia and Montenegro: “Measurement of the radon equilibrium factor in typical residential buildings in Serbia and Montenegro and harmonization of radon measurement techniques” in order to assess congruence of different measurement techniques, and then harmonize methods in case of inconsistencies. Harmonization is of particular importance to neighboring countries, in order to avoid inconsistencies in the classification of radon risk zones along border areas. Thus, six regional laboratories took part in the intercomparison – three from Belgrade and one from Novi Sad, Serbia; one from Podgorica, Montenegro; one from Banja Luka, Bosnia and Herzegovina. All laboratories participated in the indoor radon measurements, while 4 laboratories measured radon in the soil also. The measurement methods and detectors used by the laboratories were: • for air - EPA 402-R-92-004 – Indoor Radon and Radon Decay Product Measurement Devices Protocols, ch. 3.1. with RAD 7, RTM1688-2 and RadonEye; EPA 520/5-87-005 – 1987 EERF Standard Operating Procedures for Rn-222 Measurement Using Charcoal Canisters, ch. 3.4 using adsorption on charcoal canisters; ISO 11665- 4: Measurement of radioactivity in the environment – Air Radon 222: Part 4: Integrated measurement method for determining average activity concentration using passive sampling and delayed analysis with Electretes, and • for soil gas - ISO 11665-11:2016 Measurement of radioactivity in the environment — Air: radon-222 — Part 11: Test method for soil gas with sampling at depth by using active devices RTM1688-2 and RAD 7. The measurements were performed in real conditions where the radon concentration varied following a typical daily variation. Indoor radon concentrations were measured at four locations, while radon measurements in soil were performed at one location, all at the Vinča Institute site in the period from October 1 to October 8, 2021. The exposure period was consistent with a typical soil and indoor radon measurement protocols. The radon concentration in the soil was measured at depths of 20 cm and 80 cm. The robust mean and robust standard deviation were calculated as the mean of all measured radon concentrations (excluding outliers) and their standard deviation. Reference values of indoor radon covered the wide range of concentrations: (65 ± 9) Bq m-3 , (519 ± 80) Bq m-3 , (900 ± 160) Bq m-3 , (1980 ± 160) Bq m-3 , while in the soil reference values were (13350 ± 780) Bq m-3 and (26100 ± 2400) Bq m-3 at 20 cm and 80 cm depth, respectively. In order to assess whether there is a statistically significant difference between individual measurement results and the reference value, the Z - test was used as a criterion for success. If, for the calculated z value, |z| < 2 the result is satisfactory, if 2 < |z| < 3 the result is questionable, while for |z| > 3 result is not acceptable. All results of indoor radon measurements were satisfactory, except in the case of one measurement (for the lowest reference value) with electret, that was at the detection limit. Three laboratories had satisfactory results of radon concentration measurements in the soil, while the results of one laboratory were systematically lower, with z <-3, which indicated the need for additional analysis of the causes of systematic error and the possible need to change measurement protocols and/or re-calibration of used device.

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  - U radu su prikazani rezultati ispitivanja sadržaja radionuklida u mleku i mlečnim
proizvodima u sedam gradova u Srbiji u 2015. i 2016. godini. Merenja su vršena u
okviru monitoringa radioaktivnosti životnih namirnica na teritoriji Republike Srbije u
regionima Beograda, Niša, Subotice, Zaječara, Užica, Novog Sada i Vranja. Gamaspektrometrijskom metodom su određene koncentracije
40К,
137Cs i 7
Bе. Sadržaj 90Sr
određen je metodom merenja ukupne beta aktivnosti pomoću proporcionalnog niskofonskog gasnog brojača posle radiohemijske separacije 90Sr. Rezultati pokazuju niske
nivoe specifičnih aktivnosti veštačkih radionuklida 137Cs i 90Sr u uzorcima mleka i
mlečnih proizvoda i uglavnom su na nivou vrednosti <0,1 Bq/kg. Koncentracije
prirodnog 40К i kosmogenog 7
Bе su u granicama uobičajenih vrednosti za ovu vrstu
uzoraka.
AB  - This paper presents the results of the radionuclides content measurements in milk and
dairy products from seven cities in Serbia in the period 2015 - 2016. The measurements
were carried out in the framework of the radioactivity monitoring in foodstuffs within
the territory of the Republic of Serbia in the regions of Belgrade, Niš, Subotica,
Zaječar, Užice, Novi Sad and Vranje. The activity concentrations of 40K, 137C, and 7
Be
were determined by gamma spectrometric method. The content of 90Sr was determined
by measurement of total beta activity using a low-background, proportional gas counter
after radiochemical separation of 90Sr. The results show low activity levels of artificial
radionuclides 137Cs and 90Sr in milk and dairy products samples and are generally at
the level below 0.1 Bq/kg. The concentrations of natural 40K and cosmogenic 7Be are within the normal values for this type of samples.

okviru monitoringa radioaktivnosti životnih namirnica na teritoriji Republike Srbije u

dairy products from seven cities in Serbia in the period 2015 - 2016. The measurements
were carried out in the framework of the radioactivity monitoring in foodstuffs within
the territory of the Republic of Serbia in the regions of Belgrade, Niš, Subotica,
Zaječar, Užice, Novi Sad and Vranje. The activity concentrations of 40K, 137C, and 7
Be
were determined by gamma spectrometric method. The content of 90Sr was determined
by measurement of total beta activity using a low-background, proportional gas counter
after radiochemical separation of 90Sr. The results show low activity levels of artificial
radionuclides 137Cs and 90Sr in milk and dairy products samples and are generally at
the level below 0.1 Bq/kg. The concentrations of natural 40K and cosmogenic 7Be are within the normal values for this type of samples.",

AB  - Results and conclusions of interlaboratory comparison of indoor radon in 2015 in Serbia are presented. The participants were three accredited laboratories from Serbia: Serbian Institute of Occupational Health Dr Dragomir Karajovic, Laboratory for Radioactivity and Dose Measurements at the Faculty of Sciences, University of Novi Sad and Radiation and Environmental Protection Department, Vinca Institute of Nuclear Science. The laboratories make use of the same method for radon measurement, using charcoal canisters according to US Environmental Protection Agency (EPA) protocol 520/5-87-005. Calibration of detection efficiency was performed using EPA radium standard. Radon activity concentrations were determined on the basis of the intensity of short-living radon daughters, Bi-214 and Pb-214, gamma lines. The results of intercomparison were evaluated by using the u-test, which was calculated according to the International Atomic Energy Agency criteria. In this paper, not only limitations but also the advantages and possibilities of application of this method for measuring levels of human exposure to radon are discussed.

The participants were three accredited laboratories from Serbia: Serbian Institute of Occupational Health Dr Dragomir Karajovic, Laboratory for Radioactivity and Dose Measurements at the Faculty of Sciences, University of Novi Sad and Radiation and Environmental Protection Department, Vinca Institute of Nuclear Science. The laboratories make use of the same method for radon measurement, using charcoal canisters according to US Environmental Protection Agency (EPA) protocol 520/5-87-005. Calibration of detection efficiency was performed using EPA radium standard. Radon activity concentrations were determined on the basis of the intensity of short-living radon daughters, Bi-214 and Pb-214, gamma lines. The results of intercomparison were evaluated by using the u-test, which was calculated according to the International Atomic Energy Agency criteria. In this paper, not only limitations but also the advantages and possibilities of application of this method for measuring levels of human exposure to radon are discussed.",

AB  - Radon problem has a special attention in many countries in the world and the most of them have established national radon programmes. The radon issues in Serbia have not been approached in a systematic and organized way. Currently, there are many research groups and institutions working in radon field, and it is a good basis to integrate all these activities into a comprehensive national programme to define the strategic objectives and action plan for the next few years. Also, Serbia as a candidate for membership in the EU is obliged to harmonize its legislation, including the field of radiation protection in which the radon issues has an important role. In this report, a brief history of radon research, present status and plans for the future activity on radon issues in Serbia are presented. Regarding the long-term plans, the establishment and implementation of the Radon Action Plan with the primary goal of raising awareness about the harmful effects of public exposure to radon and implementing a set of measures for its reduction. In that sense, the synergy between the national, regional and local organizations responsible for public health and radiation protection must be achieved.

AB  - Laboratorija za ispitivanje radioaktivnosti, Instituta za medicinu rada Srbije”dr Dragomir Karajović”, preko 50 godina vrši kontinuirana merenja u okviru Programa monitoringa radioaktivnosti životne sredine Republike Srbije. U radu su prikazani rezultati merenja ukupne beta aktivnosti, kao i specifične aktivnosti 137Cs i 90Sr, različitih uzoraka iz životne sredine, u periodu 1985–2015. godine, koji obuhvata i černobilјski akcident, koji se dogodio u aprilu 1986. godine. Određivanje aktivnosti 137Cs, vršeno je gamaspektrometrijskom metodom pomoću HPGe-detektora efikasnosti 24% i 40%. Za određivanje aktivnosti 90Sr korišćena je radiohemijska metoda odvajanja 90Sr koja se zasniva na oksalatnom izdvajanju Ca i Sr, žarenju do oksida i korišćenju aluminijuma kao povlačivača za 90Y. Merenje aktivnosti 90Sr i ukupne beta aktivnosti vršeno je na: 1) antikoincidentnom alfa-beta brojaču “Countmaster” efikasnosti 24% i 2) automatskom niskofonskom alfa-beta proporcionalnom gasnom brojaču PIC-WPC-9550, efikasnosti 42%. Analizirani su reprezentativni uzorci zemlјišta, vazduha, padavina, vode za piće, kao i različitih vrsta prehrambenih proizvoda, sa lokacija predviđenih Programom monitoringa. Uzorci zemlјišta za ispitivanje sadržaja radionuklida uzimani su u Beogradu, Zaječaru, Nišu, Novom Sadu, Subotici, Vranju i Užicu. Uzorci vazduha za ispitivanje sadržaja radionuklida uzimani su u Beogradu (Karađorđev park i Zeleno brdo), Subotici i Nišu, neprekidno u toku 24 sata, svakog dana prosisavanjem najmanje 300 m3 vazduha kroz filter papir poznate efikasnosti, na visini od 1 m iznad tla. Uzorci čvrstih i tečnih padavina uzimani su u Beogradu (Karađorđev park i Zeleno brdo), Kragujevcu, Zaječaru, Zlatiboru, Nišu, Novom Sadu, i Subotici, svakodnevno u toku 24 sata na visini 1 m iznad tla. Uzorci vode za piće iz vodovoda uzimani su svakodnevno (Beograd, Kragujevac, Kraljevo, Niš, Novi Sad, Subotica, i Čačak). Uzorci životnih namirnica i mleka uzeti su sa lokacija u Beogradu, Subotici, Novom Sadu, Nišu, Užicu (Zlatibor), Zaječaru i Vranju. Sadržaj radionuklida u ljudskoj hrani ispitivan je na uzorcima mleka, mesa, hleba (pšeničnog, kukuruznog), dve vrste sezonskog voća i tri vrste sezonskog povrća. Uzorci ljudske hrane uzimaju se iz primarne proizvodnje i sadržaj radionuklida ispituje se prema dozrevanju vegetacije i uzgoju (za meso). Uzorci mleka uzimani su svakodnevno, a analizirani su zbirni mesečni uzorci. Institut je do 2011. godine radio kompletan monitoring u Republici Srbiji po programu koji je propisan zakonskom regulativom. Od 2011. godine uzorkovane su vode za piće, padavine, vazduh i zemlja na teritoriji opštine Beograd, a uzorci hrane su uzorkovani po programu monitoringa u Republici Srbiji. Rezultati su pokazali nagli porast radioaktivnosti u životnoj sredini u 1986. godini, neposredno posle černobilјskog akcidenta. Najveće prosečne godišnje vrednosti koncentracije radionuklida izmerene su 1986. i 1987. godine. Aktivnost radionuklida 137Cs u prehrambenim proizvodima bila je maksimalna u uzorcima žitarica i iznosila je 244,3 Bq/kg. Aktivnost radionuklida 90Sr bila je maksimalna u mlečnim proizvodima - 6,44 Bq/kg. U vodi za piće aktivnosti 137Cs i 90Sr bile su 0,054 i 0,072 Bq/l, respektivno. U 1986. godini, srednje godišnje vrednosti u padavinama, ukupne beta aktivnosti, specifične aktivnosti 90Sr i 137Cs iznosile su: 1078 Bq/m2, 8,59 Bq/m2 i 202 Bq/m2, respektivno. Srednja godišnja vrednost ukupne beta aktivnosti u vazduhu u 1986. godini je bila 468 mBq/m3. Najveće specifične aktivnosti 90Sr u zemlјištu izmerene su 1986. godine na dubini 0-5 cm - srednja godišnja vrednost iznosila je 3,5 Bq/kg. Najveće specifične aktivnosti 137Cs u zemlјištu Srbije izmerene su 1988. godine na dubini 0-5 cm - srednja godišnja vrednost iznosila je 128,7 Bq/kg. Najveće specifične aktivnosti 137Cs u zemlјištu izmerene su 1988 i 1989. godine na Zlatiboru gde su srednje godišnje vrednosti iznosile 229,8 Bq/kg i 324,8 Bq/kg, respektivno. U naredne tri godine usledio je brzi pad radioaktivnosti, da bi se do 1991. godine, u najvećem broju uzoraka, koncentracije ispitivanih radionuklida stabilizovale na prečernobilјske vrednosti, osim 137Cs koji se, zbog dugog vremena poluraspada (30,17 godina) i količina deponovanih kao posledica akcidenta, još uvek može naći u uzorcima zemlјišta.
AB  - Radioecology Department of the Serbian Institute of Occupational Health, "Dr Dragomir Karajović", is over 50 years engaged in continuous measurements of radioactivity, in the framework of the program of radioactivity monitoring in the environment of the Republic of Serbia. The paper presents the results of measurements of the total beta, 137Cs and 90Sr activity concentrations in different samples in the period 1985-2015, which includes the Chernobyl accident, that occurred in April 1986. Determination of 137Cs activity concentrations was carried out by gamma spectrometric method using HPGe-detectors having efficiencies of 24% and 40%. For the determination of 90Sr radiochemical separation technique was used. Measurement of 90Sr and total beta activity was carried out by: 1) anticoincidence alpha-beta counter "Countmaster" with the efficiency of 24% and 2) automatic low background, alpha/beta gas proportional counter PIC-WPC-9550, with 42% beta efficiency. Until 2011, complete radioactivity survey in the Republic of Serbia was carried out by our Institute, according to the official radioactivity monitoring program. Since 2011 samples of drinking water, precipitation, air and soil, were collected from the territory of Belgrade, and food samples were collected according to the monitoring program of Serbia. The results showed a sharp rise in the environmental radioactivity in 1986, shortly after the Chernobyl accident. The highest average annual value of radionuclide activity concentrations were measured in 1986 and 1987. The activity of the radionuclide 137Cs in food products was maximized in samples of cereals and amounted to 244,3 Bq/kg. The activity of the radionuclide 90Sr was maximized in dairy products 6,44 Bq/kg. In drinking water 137Cs and 90Sr were 0,054 Bq/l and 0,072 Bq/l, respectively. In 1986, mean annual values of total beta activity, activity concentrations of 90Sr and 137Cs, in precipitation were 1078 Bq/m2, 8,59 Bq/m2 and 202 Bq/m2, respectively. The average annual value of total beta activity in the air in 1986 was 468 MBq/m3. The highest activity concentrations of 90Sr in the soil were measured in 1986, annual average value was 3,5 Bq/kg. The largest activity concentration of 137Cs in the soil was measured in 1988, and average annual value was 128,7 Bq/kg. In the next three years, a rapid decline of radioactivity occurred, and so, by 1991, in the majority of tested samples, the radionuclide concentrations were stabilized at pre-Chernobyl values except for 137C which, due to the long half-life (30 years) and quantities deposited as a consequence of the accident, can still be found in the soil samples.
