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. Konačno, data je procena daljeg razvoja problematike radona.
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  - 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  - U ovom radu su odredjeni transfer faktori 137Cs iz tla u biljke koje se koriste u
tradicionalnoj medicini na teritoriji centralne Srbije. Transfer faktori (TF) su
računati kao odnos aktivnosti suvog biljnog uzorka i aktivnosti suvog uzorka
zemlje. Specifične aktivnosti 137Cs u uzorcima su merene gama spektrometrijskom
metodom koristeći koaksijalni germanijumski detektor. Absalom model je
primenjen za teorijsko predviđanje količine 137Cs koja prelazi u biljke na osnovu
određenih karakteristika tla: pH vrednost, sadržaj kalijuma, humusa i gline.
Vrednosti transfer faktora dobijene pomoću Absalom modela su u opsegu od 0,011
do 0,307, gde je srednja vrednost 0,071. Eksperimentalno određena srednja
vrednost je 0,069, pri čemu je uočeno dobro slaganje sa teorijski predviđenom
vrednošću. Prisustvo 137Cs u biljkama je u najvećoj meri posledica akcidenta u
Černobilju, pri čemu se sadašnje izračunate vrednosti transfer faktora mogu
koristiti za eventualnu procenu koncentracije aktivnosti 137Cs u lekovitim biljkama
u vreme akcidenta u Černobilju.
AB  - Transfer factors 137Cs from soil to plants used in traditional medicine were
determined. The transfer factors (TF) were calculated as Bq kg-1 of dry plant per
Bq kg-1 of dry soil. Mass activity concentrations of 137Cs in soil and plant samples
were measured with high purity germanium detector (HPGe). The Absalom
model was used for determination of the amount of 137Cs transferred from soil to
plant based on soil characteristics such as pH, exchangeable potassium, humus
and clay contents. The estimated transfer factors were in the range from 0.011 to
0.307 with an arithmetic mean of 0.071, median of 0.050, geometric mean of
0.053 and GSD of 2.08. This value agreed well with that calculated from the
measurements of 0.069.

vrednošću. Prisustvo 137Cs u biljkama je u najvećoj meri posledica akcidenta u
Černobilju, pri čemu se sadašnje izračunate vrednosti transfer faktora mogu
koristiti za eventualnu procenu koncentracije aktivnosti 137Cs u lekovitim biljkama
u vreme akcidenta u Černobilju., Transfer factors 137Cs from soil to plants used in traditional medicine were
determined. The transfer factors (TF) were calculated as Bq kg-1 of dry plant per
Bq kg-1 of dry soil. Mass activity concentrations of 137Cs in soil and plant samples
were measured with high purity germanium detector (HPGe). The Absalom
model was used for determination of the amount of 137Cs transferred from soil to
plant based on soil characteristics such as pH, exchangeable potassium, humus
and clay contents. The estimated transfer factors were in the range from 0.011 to
0.307 with an arithmetic mean of 0.071, median of 0.050, geometric mean of
0.053 and GSD of 2.08. This value agreed well with that calculated from the
measurements of 0.069.",

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  - 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  - As optical fibres are used ever more extensively in space applications, nuclear industry, medicine and high-energy physics experiments, it has become essential to investigate the influence of ionizing radiation on their characteristics. In this work, the radiation-induced attenuation at 530 nm is investigated experimentally in step-index multimode polymethyl-methacrylate plastic optical fibres exposed to low dose-rate gamma radiation. Cumulative doses ranged from 50 Gy to 500 Gy. The radiation induced attenuation has been empirically found to obey the power law RIA = aD(b), where D is the total radiation dose and a and b are the constants determined by fitting.

AB  - In this work, we present the experimental study of the radiation-induced attenuation in step-index polymethyl-methacrylate based plastic optical fibre by exposure to low dose rate ionizing radiation. The low dose exposure has been found to induce significant permanent attenuation in plastic optical fibres. Based on the experimental results, the formula between radiation-induced attenuation and radiation dose is obtained accordingly. The recovery properties of plastic optical fibre also were investigated. The fibre begins to recover immediately after irradiation, but it does not fully recover, i.e. the irradiation leads to permanent damage of polymer. (C) 2012 Elsevier Ltd. 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.
