AB  - Measurement of radon (222Rn) concentration using charcoal filters according to the EPA 520/5-87-005 method is performed in Radiation and Environment Protection Department of Vinča Institute for Nuclear Sciences on NaI scintillation detectors. Concentration of radon adsorbed on active charcoal is determined indirectly, by gamma spectrometry of its daughter products via their gamma peaks at 295 keV, 352 keV (214Pb) and 609 keV (214Bi). In order to assure the reliability of the measurement results, and in accordance with Standard ISO 17025/17 quality control and quality assurance (QA/QC) procedures needs to be applied. Related activities ought to be planned, described in the quality control documentation, performed in a systematic manner, recorded and reviewed. First, the energy and efficiency calibration of the detection system needs to be performed in a proper manner. The NaI scintillation spectrometer is internally calibrated using the certified radioactive 226Ra standard in charcoal matrix and in the geometry identical to the measurement geometry, produced by Czech Metrology Institute and traceable to Bureau International des Poids et Mesures (BIPM). As defined in laboratory’s procedures a regular quality control of the NaI scintillation detector is performed once a week. Quality control activities include the background measurement and measurement of adequate reference material. Gross background count rate in the energy region of interest is used to verify that the detector and shield have not been contaminated and that there is no significant variation of the background. Reference material used is the soil sample with known content of 226Ra. Gross count rate in the reference material spectrum is used to check the energy and efficiency calibration. These values are recorded and verified if they are within the acceptance limits. Obtained results, together with acceptance limits, for a certain period (one year usually) is graphically presented in the control charts. The acceptance limits for background count rate and reference material gross count rate in the energy region of interest are defined according to the statistical analysis of the data from previous QC period. The mean and standard deviation is calculated and the acceptance limits are set to be ±2σ and ±3σ. QC measurement results falling between ±2σ are considered to be satisfactory, while those falling inside ±3σ are warning. QC measurement results exceeding ±3σ indicate that there is a problem with the measurement system and that analysis of causes and design and application of corrective measures are needed. Analysing the control charts for the previous QC period (year 2022) showed that the controlled parameters were within the defined limits of acceptance. Occasional discrepancies, mainly due to background variation, were minor and were addressed immediately. Background variation was treated simply by repeated measurements after additional ventilation of the measurement laboratory

Hp(3), are not regularly used at the workplaces in Serbia, even though the individual monitoring method is
accredited and available at the dosimetry service. Type testing of Hp(3) dosemeters based on LiF: Mg,Ti, placed in
modified ring holders was done following the changes in ISO 4037:2019 and IEC 62387:2020. The type testing
was done by varying radiation-based influence quantities: photon energies ranging from 33.3 keV up to 1.25
MeV, angle of incidence values of 0◦, 45◦, 60◦, 75◦, dose range from 0.05 mSv to 10 Sv. The results show that the
passive dosimetry monitoring system satisfies IEC 62387:2020 requirements in the mandatory range of influence
quantities, except for the lowest tested energy of 33 keV, when incident radiation angle is ±60◦ and higher.

AB  - Accuracy of measurement in individual dosimetry monitoring service is achieved by performing calibration of dosemeters, ensuring that the measured values are traceable to the primary standard for the quantity of interest. Even though a dosemeter can exhibit remarkable performance in the reference calibration radiation field (e.g. 137Cs), its performance can greatly differ under certain conditions. Effects of different influence quantities need to be examined to ensure that the dosemeters are reliable for use in a specific ionizing radiation practice. The most significant radiation characteristic influence quantities are the radiation energy, angle of incidence and dose (rate). International standards issued by IEC and ISO define radiation conditions and procedures for dosemeter type testing under effects of different radiation, environmental and mechanical influence quantities. Dosemeter performance is expressed in terms of relative response and is evaluated by comparing with defined limits of variation, taking into account the measurement uncertainty, according to [IEC 62387:2020, IEC, 2020]. A passive dosimetry system based on LiF:Mg,Ti thermoluminescent dosemeters (TLD) was tested for the effects of photon energy and angle of incidence in two dosemeter orientations, horizontal (up/down) and vertical (left/right), for the measurement of personal dose equivalent (Hp(10) and Hp(0.07)). The dosemeters were read out on the Harshaw TLD™ Model 6600 Plus Automated Reader (Thermo Fisher Scientific, USA), calibrated in 137Cs reference field. Low-energy X-ray reference field N-40, established according to ISO 4037-1:2019 [ISO 4037, ISO, 2019] and ±45°, ±60° angles of incidence were used to examine the passive dosimetry system performance. Limits of variation from -29 % to +67 %, defined in [IEC 62387:2020, IEC, 2020] for energy and angular relative response, were used for performance evaluation. The overresponses for Hp(10) for 45° and 60° were (51 – 62) % and (76 – 88) %, respectively. The results for Hp(0.07) for 45° and 60° were (66 – 69) % and (79 – 95) %, respectively. Thus, for both quantities it was observed that the criteria are met for the angle of ±45°, while for ±60° neither comply with the standard, for both dosemeter orientations, when uncertainties are taken into account. This shows that tested TLD system has high overresponse in low energy photon fields when larger angle of incidence values is encountered. The response could be improved if dosemeters are calibrated using appropriate reference calibration field or if different dosemeter holder is employed.

AB  - Ionization chambers and solid state detectors incorporated into multimeters are often used for quality control in different modalities of medical imaging and diagnostic radiology. The equipment to be used in the routine QC procedures needs to be calibrated under well-known radiation conditions (known as radiation qualities) defined by the international standards. International standards IEC 61267:2005 [IEC 62167, IEC 2005] and IAEA TRS 457:2007 [IAEA TRS 457, IAEA 2007] cover general radiography and fluoroscopy radiation qualities (abbreviated as RQR and RQA series, in the voltage range from 40 kV to 150 kV), and computerized tomography radiation qualities (abbreviated as RQT series, in the voltage range from 100 kV to 150 kV), among other. In the field of mammography reference radiation fields are defined for molybdenum anode/filtration combination (Mo/Mo, abbreviated as RQR-M series, in the voltage range from 25 kV to 35 kV). Since Mo/Mo mammography units are widespread and available at hospitals they have been included in the standard [IEC 62167, IEC 2005]. Even so, Secondary Standard Dosimetry Laboratories (SSDLs) that are performing calibrations of QC dosimeters for end-users, rarely have availability of such anode/filtration combination under reference laboratory conditions. SSDLs most often employ X-ray generators with W/Al combinations. Additionally, nowadays many different combinations of anode/filtration are present in mammography units of different manufacturers that are commonly used in the hospitals. Multimeters are often sensitive to spectral changes caused by different anode/filter combination, so it is doubtful that the traceability established for one anode/filter combination can be used to measure doses for another combination. Measurements with different solid state detectors were performed under laboratory conditions with W/Al radiation qualities established in the SSDL. In the future, research will be expanded to clinical conditions in radiation fields produced by mammography units which employ Mo/Mo, Mo/Rh, Rh/Rh, W/Rh and W/Ag. Dosimeter response will be evaluated based on the dependency of 1st HVL which is correlated to radiation output of the X-ray generator (the incident photon spectra).

AB  - Thermoluminescent dosimetry is a widely used passive dosimetry method for estimating protection quantities i.e. the effective or equivalent dose. When the thermoluminescent dosemeters (TLD) are irradiated, they store the dose information through the processes of ionisation and subsequent trapping of charge carriers. The charge carriers in TLD crystalline material move from the ground state to the higher energy states (trapping centres) that are partially stable at room temperature. By heating the material, charge carriers leave the metastable energy states and recombine at recombination centres, emitting light (glow). The heating procedure gives rise to a glow curve (GC) – the light intensity as a function of temperature and time. By calibrating the TLD reader, the area under the GC is converted to a dose value (e.g., personal dose equivalent, Hp(10)). The shape of the GC depends on the time-temperature profile (TTP) defined for each TLD material separately and may be regular or possess some anomalies. Inspecting the GC shape, as one of quality control measures, is usually conducted qualitatively and performed by trained TLD service staff. Hence, this paper presents the implementation of the machine learning Time Series Forest (TSF) method for the classification of anomalous GCs of LiF:Mg,Ti based TLD. TSF is a tree – ensemble method that combines entropy gain and distance measure for evaluating splits. This method shows significant computational efficiency compared to the well – known one – nearest – neighbour classifier. The dataset used for the TSF method consists of 201 normalized GCs exported by the software supplied with Harshaw 6600 Plus Automated Reader – WinREMS. The dataset is labelled into five different classes: (1) regular shape, (2) spikes at random positions, (3) TLD signal in the low – temperature region, (4) TLD signal in the high – temperature region, and (5) shift of the entire GC to higher temperatures. A random split of the dataset into training and testing in a 70/30 training/test ratio was performed, while the 10 – fold cross – validation was used for the hyperparameter tuning. The results showed that the TSF method can classify four different anomalies for GC with an accuracy of 96% and a macro average F1 score of 96%.

abstract = "Thermoluminescent dosimetry is a widely used passive dosimetry method for estimating protection quantities i.e. the effective or equivalent dose. When the thermoluminescent dosemeters (TLD) are irradiated, they store the dose information through the processes of ionisation and subsequent trapping of charge carriers. The charge carriers in TLD crystalline material move from the ground state to the higher energy states (trapping centres) that are partially stable at room temperature. By heating the material, charge carriers leave the metastable energy states and recombine at recombination centres, emitting light (glow). The heating procedure gives rise to a glow curve (GC) – the light intensity as a function of temperature and time. By calibrating the TLD reader, the area under the GC is converted to a dose value (e.g., personal dose equivalent, Hp(10)). The shape of the GC depends on the time-temperature profile (TTP) defined for each TLD material separately and may be regular or possess some anomalies. Inspecting the GC shape, as one of quality control measures, is usually conducted qualitatively and performed by trained TLD service staff. Hence, this paper presents the implementation of the machine learning Time Series Forest (TSF) method for the classification of anomalous GCs of LiF:Mg,Ti based TLD. TSF is a tree – ensemble method that combines entropy gain and distance measure for evaluating splits. This method shows significant computational efficiency compared to the well – known one – nearest – neighbour classifier. The dataset used for the TSF method consists of 201 normalized GCs exported by the software supplied with Harshaw 6600 Plus Automated Reader – WinREMS. The dataset is labelled into five different classes: (1) regular shape, (2) spikes at random positions, (3) TLD signal in the low – temperature region, (4) TLD signal in the high – temperature region, and (5) shift of the entire GC to higher temperatures. A random split of the dataset into training and testing in a 70/30 training/test ratio was performed, while the 10 – fold cross – validation was used for the hyperparameter tuning. The results showed that the TSF method can classify four different anomalies for GC with an accuracy of 96% and a macro average F1 score of 96%. According to the obtained results, it is possible to conclude that the TSF is a promising candidate method that could be implemented as a new software package for automated GC quality control within the TLD service",

AB  - Clinical mammography units utilize compression paddle for breast compression during exposure. When compression paddle is released, it returns to a default position which varies between different mammography units. This default position is commonly used in quality control procedures. Guidelines for quality control testing in mammography propose measuring the half-value layer (HVL) by placing added filtration on compression paddle while multimeter is positioned on the mammography unit's detector. The influence of compression paddle positioning on HVL measurements was studied under laboratory conditions. The difference in HVL values with and without the presence of the plate is not insignificant, the positioning of the plate also has a significant impact on the measurements.

AB  - The aim of this work is to examine the accuracy of the delivered dose inside the blood irradiator using TL dosimeters. The TL dosimeters were placed behind the lead plate and were irradiated with absorbed dose values ranging from 50 mGy to 5 Gy in the 60Co reference radiation field. The deviations of the TL dosimeter readings in relation to the delivered values of the absorbed dose range from 7.8 % to 19.6 % with satisfactory linearity over the entire range of delivered doses (R=0.997). Monte Carlo simulations were used to determine the conversion coefficients for the application of this method in the 137Cs radiation field for devices that work with this type of radiation source.

AB  - A need for detailed testing of individual monitoring systems used in accredited service at the Vinca Institute of Nuclear Sciences was recognized following changes in individual, workplace, and environmental monitoring passive dosimetry systems acceptability criteria stated in IEC 62387:2020 and changes related to reference fields used in radiation protection defined in ISO 4037:2019. Reliability and accuracy of dosimetry data acquired by passive dosimetry systems used for individual monitoring is assured by carrying out type tests. In this manner, the effects of different radiation influence quantities are examined. Passive dosimetry systems comprised of an LiF:Mg,Ti (TLD-100) detector card placed in two different holder models (8814 and 8850) and the Harshaw TLD Model 6600 Plus Automated Reader were tested. Type tests were done in an extended range of photon energies from 40 keV up to 1.25 MeV, angle of incidence values of ±45° and ± 60° for both vertical and horizontal dosimeter orientation, and in the dose range from 0.05 mSv to 1 Sv. Both dosimetry system configurations perform in line with IEC 62387:2020 within mandatory range for tested influence quantities. Dosimeters that use the 8850 holder type showed less pronounced energy and angular dependence of the response in the low-energy range.

AB  - Light Absorbing Carbon (LAC) or Black carbon (BC) is one of the most important components of fine particulate matter (PM2.5), which is formed through the incomplete combustion of fossil fuels, biofuels and biomass. Based on a number of studies, it has been shown that carbonaceous particles significantly affect air quality/environment and they are an important factor in the carbon cycle and climate change. BC, as one of the constituents of carbonaceous respirable particles, has the property of absorbing light and leads to an increase in the annual average air temperature. Therefore, its quantitative analysis and differentiation for determination of potential radiative effects is extremely important. The BC concentration is usually determined by using thermal or optical methods. In this paper, the results of the application of multiwavelength optical technique for BC estimation which is based on measuring the intensity of absorption/transmission of light through samples of deposited aerosols on PTFE filters, are presented. Sample collection was conducted at Belgrade suburban background site, in heating and nonheating seasons, using low-volume air samplers. In order to estimate the BC concentration of different particle diameters, measurements were performed by using the MABI ANSTO instrument, with LEDs that emit light at seven different wavelengths: 405 nm, 465 nm, 525 nm, 639 nm, 870 nm, 940 nm and 1050nm. The measurement procedure is started by determination of the value of light transmission I0 through an unexposed or blank filter at different wavelengths. After sampling, the estimation of light transmission I through the exposed filters was performed. Before estimation of BC concentration, the light-absorbing coefficient (babs) at each wavelength was determined separately. More intense variations in the values of babs were observed, which most likely occur due to the change in the nature of the pollution sources at the sampling site. The accuracy of the BC concentration depends on the value of the mass absorption coefficient (ε) estimated experimentally and whose values are compared with the predefined manufacturer values. BC generated by combustion at lower temperatures is better absorbed at shorter wavelengths. On the other hand, BC generated through high-temperature processes is better absorbed in the infrared region of the electromagnetic spectrum. Therefore, the differences of BC concentrations at two boundary wavelengths: 405 nm and 1050 nm were analyzed. Finally, seasonal BC variations were observed, with increased values in the winter and autumn periods compared to the summer period.

AB  - The regular participation of an accredited individual monitoring service (IMS) in the international and/or interlaboratory intercomparisons (IC) is required according to ISO/IEC 17025:2017 standard, General requirements for the competence of testing and calibration laboratories. By taking the part in an IC, IMS shows competence, reliability, and has an opportunity to learn further and improve its measurement method. The European Dosimetry Group (EURADOS) Working Group 2 (WG2) has acknowledged the value of the regular IC and also found that data and results from it are fundamental for the harmonization of the measurement process [1]. Thus, EURADOS started a self-sustained program of IC for IMS for external radiation on a biannual basis. The results of an accredited IMS at the Department of Radiation and Environmental Protection, “VINČA” Institute of Nuclear Sciences, Belgrade, Serbia (IMS VINS) in the EURADOS IC for the period 2010-2020 (excluding 2014) are presented. IMS VINS use thermoluminescent whole body dosemeters based on two TLD-100TM (Thermo Scientific™ Harshaw™, USA) detectors. The readouts are done on the Harshaw TLD™ Model 6600 Plus Automated Reader (Thermo Fisher Scientific, USA). The whole glow curve is used for dose estimation (all of 200 channels). The calibration of the dosimetric system is done twice a year in S-Cs (previously in S-Co) field at the secondary standard dosimetry laboratory (SSDL VINS), according to ISO 4037-3:2019. The IC had 40 different reference values of personal dose equivalent, Hp(10) in noted period ranging from 0.431 mSv to 501 mSv. There were 20, 16, 22, 22, 20 dosemeters irradiated in year 2010, 2012, 2016, 2018, 2020, respectively. The radiations were done in 12 different fields: N-60, S-Co, S-Cs, N-40, N-150, S-Cs+Sr90, S-Cs+N-40, W-110, S-Cs+W-250, W-60, S-Cs+W-80, and S-Cs+N-150. The relative response (R) range is from 0.23 to 2.26. Quantile values for R are: 0.23, 0.79, 0.90, 1.1, and 2.26, respectively for (0%, 25 %, 50 %, 75 % and 100 % of points). Mean and standard deviation of R are 0.97 and 0.30, respectively. The performance limits are established according to ISO 14146 trumpet-curve [1]. Due to trumpet-curve there were 6 outliers (2 in 2010, 4 in 2016). All of the outliers were for reference dose around 1 mSv and lower. One outlier from 2010 was irradiated in N-40 field and 30° of incident angle. The other outlier was irradiated in the S-Cs field, without any rotation, and thus should have had a satisfying response. The possible explanation is an insensitive TL detector. The outliers in 2016 were all for N-40 quality and ±60° angle. Thus, considering the low number of outliers (only one true outlier) and expected dosemeters faulty response for given irradiation parameters, we conclude that the IMS VINS dosimetry system had satisfactory behavior during IC from 2010-2020.

AB  - Passive solid state dosimeters, such as thermoluminescence dosimeters, provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective of this paper is to provide a comprehensive review on the use of thermoluminescent dosimetry methods for monitoring radiation dose in the environment. The article presents the part of the research results of the project PREPAREDNESS (EMPIR 2016 call for Metrology for Environment joint research project) with a particular objective to harmonize procedures used by dosimetry services, relevant authorities and Institutes across the Europe. To achieve this, different monitoring routines that are based on passive environ mental dosimetry methods are investigated. Differences in performing specific steps such as preheating, reading, annealing, minimizing fading, and others, are analyzed. The investigation was performed by means of qualitative literature review that showed the lack of information about specific steps. The conclusion of this work is that thermoluminescent dosimetry measurement system has to be type-tested even though the testing procedure is complicated. In addition to this, control dosimeters should be introduced, International Organization for Standardization protocols should be followed during calibration, and finally, parameters influencing the measurement uncertainty have to be identified and well understood in order to pro duce ac cu rate dose measurement results.

AB  - This paper presents the results of measurements of the ambient dose equivalent rate of the gamma radiation performed within the regular monitoring of the coal-fired power plant „Kostolac“, performed by the Radiation and Environmental Protection Department of „Vinča“ Institute of Nuclear Sciences. Ambient dose equivalent rate is measured in the air, at 1 m height above the ground at defined sites within the territory of the power plant and the ash and slag disposal dumps, at the moment of sampling at these sites, using a dosimeter with a scintillation probe. Also, during the yearsin which the monitoring was performed, continuous measurements of the ambient dose equivalent on the location of settlements in the vicinity of the power plant were conducted, using termo luminescent dosimeters (TLD). The comparison of the long term measurements and measurements performed on the sampling sites, a conclusion about the influence of power plant on the living and working environment can be reached

AB  - The results of the post-irradiation fading of whole body dosemeters based on two TLD-100TM (Thermo Scientific™ Harshaw™, USA) detectors are presented. The dosemeters are regularly used by accredited individual monitoring service (IMS) at Vinca Institute of Nuclear Science (VINS), Belgrade, Serbia. The testing of post-irradiation fading was carried out according to International Electrotechnical Commission (IEC) 62387:2020 standard. The irradiations are done in S-Cs137 field at secondary standard dosimetry laboratory (SSDL) at VINS, according to International Organization for Standardization document ISO 4037-3:2019. The chosen reference personal dose equivalent value was 3 mSv. The research was carried out in the period from October 2020 to February 2021, and it lasted 128 days. The frequency of irradiations was approximately 7 days, while 3 periods between irradiations were longer than 10 days, due to COVID-19 pandemic. The irradiations were performed at different dates; thus, all dose readouts were done on the same day to prevent influence of reader’s instabilities. The irradiated dosemeters were stored at the same room where the average temperature was nearly 20°C. There were 14 groups with 6 dosemeters for irradiation and 2 dosemeters for natural background radiation level correction. The reader was Harshaw TLD™ Model 6600 Plus Automated Reader (Thermo Fisher Scientific, USA). The whole glow curve was used for dose estimation (all of 200 channels). The time as influence quantity was considered to be of type F, thus the range of relative response was limiting factor in the analysis. The results showed that the maximum measurement time tmax is 72 days for deep dose (Hp(10)) detector, and 85 days for shallow dose (Hp(0.07)) detector. Thus, the standard’s requirement is satisfied, as it is required minimum of 30 days. The relative response range for all of the 14 groups was from 0.82 to 1.14 and from 0.83 to 1.17, for deep and shallow dose, respectively. The research has limitation as the irradiations were organized aligned to COVID-19 working schedule. One of the consequences of this timetable is lack of 7 days’ time point, thus the values from 16 days’ time point was used as referential.

The dosemeters are regularly used by accredited individual monitoring service (IMS) at Vinca Institute of Nuclear Science (VINS), Belgrade, Serbia. The testing of post-irradiation fading was carried out according to International Electrotechnical Commission (IEC) 62387:2020 standard. The irradiations are done in S-Cs137 field at secondary standard dosimetry laboratory (SSDL) at VINS, according to International Organization for Standardization document ISO 4037-3:2019. The chosen reference personal dose equivalent value was 3 mSv. The research was carried out in the period from October 2020 to February 2021, and it lasted 128 days.

AB  - 16ENV04 Preparedness je projekat iz poziva EMPIR 2016 za zaštitu životne sredine. Glavni cilj projekta je poboljšanje pripravnosti za nuklearne i radiološke incidente i akcidente, koji bi mogli da se dogode u budušnosti. Pripravnost će biti poboljšana tako što će se izvršiti istraživanja u nekoliko pravaca: upotreba bespilotnih letelica za radiološka merenja, upotreba mobilnih sistema za uzorkovanje vazduha, istraživanje mogućnosti  korišćenja radioloških podataka iz nevladinih mreža i korišćenje sistema pasivnih dozimetara za monitoring okoline. Još jedan od načina za poboljšanje pripravnosti je smanjenje  mogušnosti bezrazložne  panike  koja  bi  mogla  da  bude izazvana  diseminacijom merenja iz nevladinih mreža i drugih izvora, što bi moglo da izazove i smanjenje poverenja u zvanične podatke. U cilju realizacije projekta, od velikog značaja su diseminacija razultata i komunikacija sa svim zainteresovanim stranama.
AB  - 16ENV04 Preparedness is a research project within the EMPIR 2016environment call. The  main  project  goal  is  to  increase  the  preparedness  for  nuclear  and  radiological incidents  and  accidents  that  might  occur  in  the  future.  The  preparedness  will  be increased  by  pursuing  several  directions  of  research:  use  of  unmanned  aerial  vehicles for radiological measurements, use of transportable air-sampling systems, investigating the crowd sourced radiological data for possible official uses and investigating the use of passive dosimetry systems for ambient monitoring. Another aspect of preparedness is to try to reduce the possibility of unwarranted panic caused by the data disseminated by citizen  networks  and  other  sources  and  to  increase  confidence  in  official  data.  To realize the project goals, communication with stakeholders and dissemination of results are of greatest importance.

AB  - Medical personnel performing interventional procedures in cardiology and radiology is considered to be a professional group exposed to high doses of ionizing radiation. Reduction of the eye lens dose limit made its assessment in the interventional procedures one of the most challenging topics. The objective of this work is to assess eye lens doses based on the whole-body doses using methods of computational dosimetry. Assessment included different C-arm orientations (PA, LAO and RAO), tube voltages (80 –110 kV) and efficiency of different combinations of protective equipment used in interventional procedures. Center position at the height of the thyroid gives best estimate of eye lens dose, with spreads of 11% (13%), 13% (17%) and 14% (13%) for the left (right) eye lens. The conversion factors of 1.03 (0.83), 1.28 (1.06) and 1.36 (1.06) to convert whole body to eye lens dose were derived for positions of first operator, nurse and radiographer, respectively. The eye lens dose reduction factors for different combinations of applied protective equipment are 178, 5 and 6, respectively.

AB  - Following the proposal of the ICRP for the reduction of the dose limit for the lens of the eye, which has been adopted by the International Atomic Energy Agency and the European Council, concerns have been raised about the implementation of proper dose monitoring methods as defined in national regulations, and about the harmonisation between European countries. The European Radiation Dosimetry Group organised a survey at the end of 2017, through a web questionnaire, regarding national dose monitoring regulations. The questions were related to: double dosimetry, algorithms for the estimation of the effective dose, methodology for the determination of the equivalent dose to the lens of the eye and structure of the national dose registry. The results showed that more than 50% of the countries that responded to the survey have legal requirements about the number and the position of dosemeters used for estimation of the effective dose when radiation protection garments are used. However, in only five out of 26 countries are there nationally approved algorithms for the estimation of the effective dose. In 14 out of 26 countries there is a legal requirement to estimate the dose to the lens of the eye. All of the responding countries use some kind of national database for storing individual monitoring data but in only 12 out of 26 countries are the estimated effective dose values stored. The personal dose equivalent at depth 3 mm is stored in the registry of only seven out of 26 countries. From the survey, performed just before the implementation of the European Basic Safety Standards Directive, it is concluded that national occupational exposure frameworks require intensive and immediate work under the coordination of the competent authorities to bring them into line with the latest basic safety standards and achieve harmonisation between European countries.

AB  - Medical staff performing interventional procedures in cardiology and radiology is considered to be a professional group exposed to high doses of ionizing radiation. With new epidemiological evidences and recently reduced eye lens dose limit, dose assessment to the lens of the eye, in the interventional cardiology, has become one of the most challenging research topics. This paper presents results of the eye lens dose assessment in interventional cardiology obtained by means of the computational dosimetry. Since placing and wearing the dedicated eye lens dosimeter is encumbering for the staff, Monte Carlo simulation provides an accurate and efficient method for obtaining an indication of doses to the eye lenses. Eye lens doses were estimated for three typical beam projections (PA, LAO, and RAO) and tube voltages ranging from 80 kV to 110 kV, with different protective equipment setups, for the first operator position. Simulations were carried out using MCNPX code. Results revealed that a whole body dosimeter worn at the thyroid center position gives the best estimate of the eye lens dose with a spread from 11 % to 18 % for the left eye. Corresponding average conversion coefficient from whole body lo the eye lens dose is estimated to be 0.18. © 2018; Vinca Inst Nuclear Sci. All rights reserved.

AB  - Following recent epidemiological evidences on effects of ionizing radiation to the eye
lens, International Commission on Radiological Protection has re-evaluated dose limit
to the lens of the eye, owing that protracted exposure to the relatively small doses and
dose rates may lead to the cataract at dose levels much lower than previously set dose
thresholds. Such satiations are typical for occupational exposure in interventional
cardiology and radiology. Occupational exposure from interventional x-ray procedures
is an area in which increased eye lens exposure may occur. Accurate dosimetry is an
important element to investigate the correlation of observed radiation effects with
radiation dose, to verify the compliance with regulatory dose limits, and to optimize
radiation protection practice. The papers presents the overview of practical methods for
eye lens doses assessment as well as typical occupational eye lens dose levels in
interventional procedures in cardiology and radiology. In addition, a methodology to
assist decision making about need for specific eye lens individual monitoring using a
dedicated passive dosimeters calibrated in terms of Hp(3) is presented in this paper.

spherical ionization chamber surrounded by spherical phantom. The goal was to obtain
the more constant energy and angular response in wide energy range in order to get
optimal geometry. The results shown that the most adequate design for secondary

AB  - Cilj ovog rada je procena efektivnih doza radiološkog osoblja profesionalno izloženih
jonizujućem zračenju u domovima zdravlja u Srbiji. Za procenu doza su primenjene dve
metode: (1) merenje ambijentalnog ekvivalenta doze, H*
(10), korišćenjem jonizacione
komore; i (2) merenje ličnog ekvivalenta doze, Hp(10), korišćenjem termoluminescentnih dozimetara (TLD). Doze su procenjene za radiologe iz devet domova zdravlja koji
rade iz kontrolisane zone zračenja i radiologe iz sedam domova zdravlja koji rade iz
nadgledane zone zračenja. Godišnje doze su date za radiologe i radiološke tehničare za
period od pet uzastopnih godina (2011-2015). Prosečna procenjena godišnja doza ne
prelazi 12 mSv, na osnovu merenja H*
(10), dok je 1,65 mSv maksimalna godišnja doza
izmerena TLD metodom. Dobijeni rezultati pokazuju da doze osoblja ne prelaze
zakonski predviđenu granicu godišnje doze od 20 mSv.
AB  - The aim of this study is to estimate the effective doses to workers occupationally
exposed to ionizing radiation in small health centers in Serbia. To assess doses two
methods were applied: (1) the measurement of the ambient equivalent dose, H*(10)
using ionization chambers routinely utilized during workplace monitoring; and (2) the
measurement of the personal equivalent dose, Hp(10), using thermoluminescent
dosemeters routinely utilized during individual monitoring. Doses were estimated for
radiologist working from controlled and supervised area. Annual doses are given for
for a period of five consecutive years (2011-2015). The average annual dose does not
exceed 12 mSv assessed by the workplace monitoring method, or 1.65 mSv measured by
the individual monitoring method. The results show that estimated doses are well below
annual dose limits of 20 mSv for the occupational exposure.

AB  - Za potrebe obuke lica za delovanje u slučaju hemijskih, bioloških, radioloških i
nuklearnih akcidenata (HBRN) uspostavljena je platforma u okviru Instituta za
nuklearne nauke Vinča (INNV). Na samoj platformi se između ostalih izvode praktična
uvežbavanja: lociranja radioaktivnog izvora, obezbeđivanja izvora i različitih scenarija
dekontaminacije. Jedna od nadležnosti Laboratorije za zaštitu od zračenja i zaštitu
životne sredine (Zaštita) je da primeni odgvarajuće mere radi kontrolisanog izlaganja
jonizujućem zračenju pojedinaca na platformi kao i radnika INNV. U ovom radu su
prikazani rezultati merenja ambijentalnog ekvivalenta doze, H*(10) pomoću termoluminiscentnih dozimetara (TLD) koji su postavljeni u cilju monitoringa okoline tokom
HBRN vežbe koja je izvedena u aprilu 2017. Merenja su vršena postavljanjem TLD na
22 lokacije na samoj platformi i van nje u trajanju od 14 dana. Izmerena srednja
vrednost H*(10) iznosi 34 µSv za posmatrani period što pokazuje da nije došlo do
značajnog povećanja ambijentalne ekvivalentne doze u odnosu na osnovni nivo
prirodnog zračenja.
AB  - For the purpose of professional responder training in the case of chemical, biological,
radiological and nuclear accidents (CBRN), a training platform was established within
the Vinca Institute of Nuclear Sciences (INNV). On the platform, among other things,
practical exercises are carried out such as: locating radioactive sources, securing
sources and various decontamination scenarios. One of the responsibilities of the
Department of Radiation and Environmental Protection (Zastita) is to apply specific
measures for the controlled exposure to ionizing radiation of individuals on the
platform as well as of INNV workers. This paper presents the ambient dose equivalent
H*(10), measured using thermoluminescent dosimeters (TLDs) that were set up to
monitor the environment during the CBRN exercise in April 2017. The measurements
were made by placing the TLD at 22 locations on the platform itself, and out of it for 14
days. The mean H*(10) is 33 µSv for the observed period, which shows that there was
no significant increase in the ambient dose relative to the background level.

AB  - The objective of this work is to assess the occupational dose in interventional cardiology in a large hospital in Belgrade, Serbia. A double-dosimetry method was applied for the estimation of whole-body dose, using thermoluminescent dosemeters, calibrated in terms of the personal dose equivalent H-p(10). Besides the double-dosimetry method, eye dose was also estimated by means of measuring ambient dose equivalent, H*(10), and doses per procedure were reported. Doses were assessed for 13 physicians, 6 nurses and 10 radiographers, for 2 consequent years. The maximum annual effective dose assessed was 4.3, 2.1 and 1.3 mSv for physicians, nurses and radiographers, respectively. The maximum doses recorded by the dosemeter worn at the collar level (over the apron) were 16.8, 11.9 and 4.5 mSv, respectively. This value was used for the eye lens dose assessment. Estimated doses are in accordance with or higher than annual dose limits for the occupational exposure.
