AB  - The objective of this work was to assess absorbed doses in organs and tissues of a rabbit, following computed tomography (CT) examinations, using a dedicated 3D voxel model. Absorbed doses in relevant organs were calculated using the MCNP5 Monte Carlo software. Calculations were perfomed for two standard CT protocols, using tube voltages of 110 kVp and 130 kVp. Absorbed doses were calculated in 11 organs and tissues, i.e., skin, bones, brain, muscles, heart, lungs, liver, spleen, kidney, testicles, and fat tissue. The doses ranged from 15.3 to 28.3 mGy, and from 40.2 to 74.3 mGy, in the two investigated protocols. The organs that received the highest dose were bones and kidneys. In contrast, brain and spleen were organs that received the smallest doses. Doses in organs which are stretched along the body did not change significantly with distance. On the other hand, doses in organs which are localized in the body showed maximums and minimums. Using the voxel model, it is possible to calculate the dose distribution in the rabbit’s body after CT scans, and study the potential biological effects of CT doses in certain organs. The voxel model presented in this work can be used to calculated doses in all radiation experiments in which rabbits are used as experimental animals.

AB  - U radu je prikazano poređenje apsorbovanih doza u brahiterapijskim planovima i Monte Karlo simulacijama u brahiterapiji pacijentkinja sa karcinomom grlića materice. U Odeljenju za brahiterapiju u Kliničkom centru Kragujevac primenjuje se mikroSelektron za intrakavitarnu brahiterapiju u HDR režimu. Ovaj uređaj koristi minijaturni radioaktivni izvor 192Ir u obliku cilindra, aktivnih dimenzija 0,6 mm × 3,5 mm, i visoke početne aktivnosti od 370 GBq.Pre terapije, vrši se kompjutersko planiranje, koje predstavlja kompjutersku rekonstruk-ciju položaja vodiča izvora u pacijentu na osnovu dva radiografska snimka, i izodozno planiranje u odnosu na željene dozimetrijske tačke. Osnovni podaci planiranja su dnevna doza, koja iznosi 700 cGy i broj frakcija; dnevna doza se isporučuje se u tri frakcije jednom nedeljno. Monte Karlo simulacije su obavljene korišćenjem MCNP6 softvera verzije 2.0 kako bi se procenila raspodela doze u materici i kritičnim organima od rizika (bešika i debelo crevo). MCNP F6 tally (MeV/g) je izabran zbog lakog konvertovanja deponovane energije u apsorbovanu dozu. Za pripremu ulaznih datoteka koje simuliraju brahi-terapiju korišćeni su matematički ORNL i voksel fantomi. Upoređivanjem izmerenih i izračunatih vrednosti može se videti da su Monte Carlo tehnike moćno sredstvo za primenu u planiranju brahiterapije.
AB  - This paper presents the comparison of absorbed doses in brachytherapy plans and Monte Carlo simulation for brachytherapy treatment of a female patient with cervix carcinoma. At the Department of Brachytherapy at the Clinical Center Kragujevac, the microSelectron after loading deviceis used for intracavitary brachytherapy in the HDR regime. This device uses a miniature radioactive source 192Ir in the form of a cylinder, active dimensions of 0.6 mm × 3.5 mm, and a high initial activity of about 370 GBq. Before therapy, computer planning is performed, which represents a computer reconstruction of the position of the source guide in the patient based on two radiographic images, and isodose planning in relation to the desired dosimetry points. Essential planning data are the daily dose and number of fractions. In this case, the daily dose is 700 cGy and is delivered in three fractions once a week. This means that the duration of this brachytherapy treatment will be a total of three weeks. Monte Carlo simulations by using MCNP6 code version 2.0 were applied for brachytherapy treatment to estimate the dose distribution in uterus and several critical organs at risk (bladder and colon). The MCNP tally f6 (MeV/g) was chosen due to easy convert energy deposition toabsorbed dose. The computational ORNL and voxel phantoms were used to prepare input files which simulate brachytherapy.By comparing measured and calculated values, it can be seen that Monte Carlo techniques are a powerful tool for application in brachytherapy planning.

AB  - Radon je prirodni radioaktivni gas, čije je prisustvo zbog svojih  karakteristika nemoguće detektovati ljudskim čulima, već ga je neophodno meriti. Iako je otkriven na početku XX veka, kada su i izmerene visoke koncentracije radona u rudnicima srebra u Češkoj, tek je četiri decenije posle pretpostavljena veza izmeĎu visoke koncentracije radona i kancera pluća, da bi se desetak godina kasnije ukazalo na radonove potomke kao moguće uzročnike kancera. Brojne epidemiološke studije su pokazale da radon sa svojim potomcima predstavlja drugi uzročnik kancera pluća posle pušenja. Važnost ispitivanja radona i njegovih potomaka je odmah uočena i u Srbiji, tako da je već na prvom skupu, tada Jugoslovenskog društva za radiološku zaštitu, održanom 1963 godine, bilo nekoliko radova posvećenih merenju koncentracije radona u rudnicima i banjama čime se dominantno bavio Institut za medicinu rada, iz Beograda. U ovoj publikaciji data je kvalitativna analiza „radonskih― radova sa prethodnih 29 simpozijuma Društva za zaštitu od zračenja. Diskutovana je aktuelnost problematike sa godinama, pregled tema koje su se širile s godinama, kao i pregled korišćenih mernih tehnika i njihov razvoj.

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  - This paper presents indoor radon concentrations and specific activities of natural radionuclides measured in soils of Kosovo and Metohija. The measurements of radon concentration were performed during two consecutive 6-month periods in two rooms of 63 houses using CR-39 detectors. The annual radon concentration ranged from 30 to 810 Bq m(-3) with the average value of 128 Bq m(-3). Almost 15% of the houses had radon concentration higher than 200 Bq m(-3). The difference between radon concentrations measured in the two 6-month periods was analyzed, showing, as expected, a slightly higher radon concentration in the winter period than in the summer period. The variation between different rooms of the same houses was also analyzed, showing that 20% of the dwellings had a significantly higher radon concentration ( GT 100 Bq m(-3)) in one room compared to the other (the coefficient of variation ranged up to 96%). The specific activities of natural radionuclides in the nearby soil were determined by gamma spectrometry. The estimated average value (and standard deviation) of Ra-226, Th-232, and K-40 specific activities were 32 (13), 35 (16), and 582 (159) Bq kg(-1), respectively. The correlation between indoor Rn-222 and Ra-226 content in soil was investigated. Only a weak correlation was found (Spearmans rho = 0.220) indicating that other factors might affect diffusion and accumulation of radon indoors, as confirmed also by the high variability between the rooms of the same houses.

AB  - Koncentracija radona je merena u zatvorenim prostorijama 14 javnih vrtića na
teritoriji grada Kragujevca. Merenja su vršena korišćenjem pasivnih UFO detektora,
koji su nakon tromesečnog izlaganja elektrohemijski tretirani. Dobijene vrednosti se
kreću u intervalu (27-145) Bq m-3. Takođe je izvršena gamaspektrometrijska analiza
uzoraka zemlje prikupljene u dvorištima vrtića, pri čemu su određene specifične
aktivnosne koncentracije 226Ra, 232Th, 40K i 137Cs čije srednje vrednosti ± standardne
devijacije iznose (34,6 ± 5,7), (42,5 ± 6,3), (414 ± 91) i (44,7 ± 40,8) Bq kg-1, respektivno. Ispitana je korelacija između koncentracije radona u zatvorenim prostorijama i sadržaja 226Ra u okolnom zemljištu.

AB  - У овом раду одређени су коефицијенти трансфера у биокинетичком моделу за
90Y-DOTATOC неуроендокриних тумора. Неуроендокрини тумори (NETs) су
малигни тумори који најчешће захватају органе гастроинтестиналног тракта и
панкреас (GEP-NETs), мада се могу јавити и на другим ткивима, као што су
плућа и ређе на дојкама, тимусу и урогениталном систему. Када су ови тумори
добро диферентовани, терапија избора је пептидна радионуклидна терапија
(PRRT), која се базира на аналозима соматостатина обележеним снажним бета
емитером, као што је 90Y, чији је максимални домет у меким ткивима 11,3 mm,
што омогућава да се са великом вероватноћом уништи велики део туморског
ткива и заустави прогресија малигне болести.
Циљ овог рада је да се на основу доступних метода мерења дистрибуције
90Y-DOTATOC у органима људског тела и на основу решења математичког
модела одреде трансфер коефицијенти за критичне органе, као и за тумор, а на
основу којих је касније могуће извршити прорачун апсорбованих доза у тим
органима и туморском ткиву.
AB  - Transfer coefficients in biokinetic model for 90Y-DOTATOC therapy of
neuroendocrinetumour (NETs) were determined in this work. These tumours are usually
treatted by DOTATOC therapy where some peptide was labeled with 90Y, which is a
strong beta emiter. The range of beta particles in soft tissues is less than 11.3 mm which
enables destroying of tumour cells with large probabiliy. The objective of this work was
to develop biokinetic model for 90Y-DOTATOC and to analytically solve obtained
equations. As a result of this model, the system with 10 equaitions and 12 unknown
constants was obtained. Two additional equations sjould be found: first one was
obtained from the normalisation of system and the second one from measurements.

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  - After the atmospheric nuclear weapon tests and Chernobyl accident large amounts
of artificial radionuclides have been released to the environment. Due to its long
half-life and chemical analogy with potassium 137Cs is one of the most hazardous
artificial radionuclides. In this paper the 137Cs activity concentrations were
measured in soil samples collected from the territory of Kragujevac city.
Seventy-four samples of undisturbed soil were collected from non-agricultural
areas during 2013. The specific activities of 137Cs were measured by gamma
spectrometry using a HPGe semiconductor detector. The average value ± standard
deviation was (43.3 ± 31.5) Bq kg-1
. This result is in the range typical for Serbia
and it is in good agreement with the average values in towns of neighbouring
counties. Kolmogorov–Smirnov's normality test revealed normal distribution of
137Cs concentrations (p=0.056). From total number of soil samples the percentage
of samples with concentration less than 50 Bq kg-1 is 63.5%, between 50 and 100
Bq kg-1 is 31.1%, and above 100 Bq kg-1 is 5.4%. Radiological risk from 137Cs
was estimated through the annual effective dose and the mean value was 7.7 μSv.

AB  - The subject of research in this paper is the vertical distribution of the 137Cs in
undisturbed soil. The presence of the 137Cs in the soil is largely a result of the
Chernobyl’s accident, which occurred in 1986. Soil samples were taken in central
Serbia, in the surroundings of the city of Kragujevac during year 2001. Specific
activities of the 137Cs in soil samples were measured by gamma spectrometric
method using coaxial germanium detector HPGe. Fifteen years after the Chernobyl
accident the largest activity of the 137Cs is within 10 cm of the upper layer of the
soil. The obtained result shows that the migration of Cs in soil is a very slow
process.

AB  - International Commission on Radiological Protection (ICRP) has decreased the annual dose limit for the eye lens from 150 mSv down to 20 mSv for occupational exposures. The operational quantity Hp (3) has been defined for eye lens dosimetry, while cylindrical phantom approximating the shape of a head was suggested for calibration purposes. The aim of the work was to provide a set of conversion coefficients that could contribute to improving the overall quality of eye lens dose assessment. The work investigated the air kerma to Hp(3,iota)conversion coefficients, Hp(3,iota)/Ka (in Sv/Gy), based on Monte Carlo simulations for a standard beam qualities, different angulations and suitable cylindrical phantom. For incident angles iota from 0(o\) to 90(o)., the conversion coefficients Hp(3,iota)/Ka were in the range 0.44-0.88 for N-40, 0.72-1.06 for N-60, 0.91-1.63 for N-80, 1.08-1.52 for N-100, 1.22- 1.62 for N-120 and 0.14-1.56 for N-150 beam quality. The conversion factors Hp(3)/Ka provided in this work are related to standard beam qualities readily available in the calibration laboratories and are suitable for application in numerous workplace situations in medicine and industry.

AB  - The survey of natural radioactivity in Kosovo and Metohija involves 180 indoor Rn-220 measurements. They were performed either in living rooms or in bedrooms of 127 individual, rural type houses, using a passive method with application of CR-39 solid-state nuclear track detectors. Detectors were deployed at a distance of GT 10 cm from the walls. Values of all 180 measurements for 127 houses give an arithmetic mean (AM) of 132 Bq m(-3). The data for indoor thoron mapping arranged within 10 km x 10 km grid cells give an AM of 118 Bq m(-3) over AM grid cells. The distribution over individual data and the grid cells can be described as normal. About 19 % of the area of Kosovo and Metohija was covered by mapping. This study includes statistical analysis and discussion of factors, such as geogenic and seasonal, which possibly affect thoron concentration, as well as comparison with simultaneous radon measurements.

AB  - This paper deals with calculated effective doses that members of real population received from radon gas and its short lived progeny during air inhalation in their dwellings at field site Kalna in Eastern Serbia. There are two crucial parameters in effective dose calculation: Dose Conversion Factor (DCF) for particular subjects (including real gender, age and physical activity level) and indoor concentration of radon and its short lived progeny in field area. According to the results of indoor radon measurements in the area of former uranium mine, Kalna, the effective dose for this real population was estimated by using the dosimetric lung model, developed by authors according ICRP Publication 66. Authentic software was developed for determination of effective dose per unit inhaled activity of radon progeny, DCF expressed in unit [mSv/WLM]. The results, obtained according to ICRP 66 dosimeter lung model, were compared with results calculated according to ICRP Publication 65. The dosimetric results were, also, compared and discussed with epidemiological approach data, according to UNSCEAR.

AB  - Radon concentration measurements were performed in all 25 primary schools in Banja Luka city, the capital of Republic of Srpska, during 2011 and 2012, using both active RAD7 continual radon measuring instruments and CR-39 passive (commercially known as Gamma) detectors. The two complimentary methods were employed not only to obtain annual averages, but also to study the dynamics of radon concentration changes during the week. For each school, average and temporal variations of radon concentrations were analysed, taking into consideration local geology, building materials and meteorological conditions. The influence of forced ventilation, caused by frequent opening of doors and windows during working hours, with typical dawn and weekend peaks is evident in most but not all schools. Elevated levels of radon concentration ( GT 400 Bq m(-3)) were found in a few schools using both methods. Although high correlation factor of 0.8 between passive and active methods was found, still short-time (one-week) measurements cannot be used for annual estimation of radon activity but only as a screening one. Thus, the conclusion concerns only long time measurements as valid indicator of annual radon activity.

AB  - Some previous studies on radon concentration in dwellings of some areas of Kosovo and Metohija have revealed a high average radon concentration, even though the detectors were exposed for three months only. In order to better design a larger study in this region, the annual measurements in 25 houses were carried out as a pilot study. For each house, CR-39-based passive devices were exposed in two rooms for the two consecutive six-month periods to account for seasonal variations of radon concentration. Furthermore, in order to correlate the indoor radon with radium in nearby soil and to improve the knowledge of the natural radioactivity in the region, soil samples near each house were collected and Ra-226, Th-232, K-40 activity concentration were measured. The indoor radon concentration resulted quite high from the average (163 Bq/m(3)) and generally it did not differ considerably between the two rooms and the two six-month periods. The natural radionuclides in soil resulted to be distributed quite uniformly. Moreover, the correlation between the(226)Ra content in soil and radon concentration in dwellings resulted to be low (R-2 = 0.26). The annual effective dose from radon and its short-lived progeny (5.5 mSv, in average) was calculated by using the last ICRP dose conversion factors. In comparison, the contribution to the annual effective dose of outdoor gamma exposure from natural radionuclides in soil is nearly negligible (66 mu Sv). In conclusion, the observed high radon levels are only partially correlated with radium in soil; moreover, a good estimate of the annual average of radon concentration can be obtained from a six-month measurement with a proper choice of exposure period, which could be useful when designing large surveys.

AB  - Metal oxide semiconductor (MOS) capacitors were fabricated with nitrided and non-nitrided sputtered oxides. The MOS structures were exposed to 2 Mrad gamma-ray dose and stored in a dry ambient for one year. Post-irradiation stability of MOS capacitors was investigated by applying Fowler-Nordheim constant current stress and monitoring the positive charge, border traps and interface states generation. It was found that nitridation increased the resistance of sputtered oxides to various defects generation under irradiation, electrical and combined radiation-electrical stress. The improved stability is explained in part by compensation of oxygen vacancy defects and Pb centers by nitrogen. (C) 2012 Elsevier B.V. All rights reserved.

AB  - Since 1996/97, indoor radon has been measured in scattered locations around Kosovo. In the most recent campaign, apart from radon, thoron and Rn and Tn progenies have also been measured. The current survey involves 48 houses, in which different detectors have been deployed side-by-side in one room, in order to measure indoor radon and thoron gas with RADUET devices based on CR-39 detectors (analysed by Japanese collaborators) and with direct thoron and radon progeny sensor (DTPS and DRPS) devices based on LR-115 detectors (analysed by collaborators from India). Estimated arithmetic mean values of concentrations in 48 houses are 122 Bq m(-3) for radon and 136 Bq m(-3) for thoron. Those for equilibrium equivalent radon concentration and equilibrium equivalent thoron concentration based on measurements in 48 houses are 40 and 2.1 Bq m(-3), respectively. The arithmetic mean value of the equilibrium factor is estimated to be 0.50 +/- 0.23 for radon and 0.037 +/- 0.041 for thoron. The preliminary results of these measurements are reported, particularly regarding DTPS and DRPS being set up in real field conditions for the first time in the Balkan region. The results are to be understood under the caveat of open questions related to measurement protocols which yield reproducible and representative results, and to quality assurance of Tn and Rn/Tn progeny measurements in general, some of which are discussed.
