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  - In recent years, computed tomography (CT) has become very common in veterinary medicine. It is well known that testicles are organs with high radiosensitivity and their function can be impaired even after exposure to low radiation doses. In this work, we calculated the absorbed radiation doses after CT was performed with different voltage/current levels and correlated it with the activity of antioxidant enzymes in rabbit testicles. Two hours after CT, the activities of catalase (CAT) and glutathione peroxidase (GSH-Px) were increased in the testicles of animals that received an absorbed dose of 29.2 mGy. The same changes, along with elevated glutathione reductase (GR) activity, were observed after 7 days in animals that received the highest absorbed dose (46.3 mGy). It would appear that absorbed doses above 27.8 mGy provoked the antioxidant reaction but the time scale of the reaction was dose-dependent. Examination of the obtained results revealed that the main denominator of CT influence was a higher current. Our results suggest that CT influences the antioxidant status in rabbit testicles. The changes in antioxidant enzyme activities were dose- and time-dependent and influenced by the applied current. © 2018 by the Serbian Biological Society.

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  - 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.

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  - 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.
