AB  - Purpose: The purpose of this paper is to present and validate an originally developed application SkinCare used for skin dose mapping in interventional procedures, which are associated with relatively high radiation doses to the patient’s skin and possible skin reactions. Methods: SkinCare is an application tool for generating skin dose maps following interventional radiology and cardiology procedures using the realistic 3D patient models. Skin dose is calculated using data from Digital Imaging and Communications in Medicine (DICOM) Radiation Dose Structured Reports (RDSRs). SkinCare validation was performed by using the data from the Siemens Artis Zee Biplane fluoroscopy system and conducting “Acceptance and quality control protocols for skin dose calculating software solutions in interventional cardiology” developed and tested in the frame of the VERIDIC project. XR-RV3 Gafchromic films were used as dosimeters to compare peak skin doses (PSDs) and dose maps obtained through measurements and calculations. DICOM RDSRs from four fluoroscopy systems of different vendors (Canon, GE, Philips, and Siemens) were used for the development of the SkinCare and for the comparison of skin dose maps generated using SkinCare to skin dose maps generated by different commercial software tools (Dose Tracking System (DTS) from Canon, RadimetricsTM from Bayer and RDM from MEDSQUARE). The same RDSRs generated during a cardiology clinical procedure (percutaneous coronary intervention—PCI) were used for comparison. Results: Validation performed using VERIDIC's protocols for skin dose calculation software showed that PSD calculated by SkinCare is within 17% and 16% accuracy compared to measurements using XR-RV3 Gafchromic films for fundamental irradiation setups and simplified clinical procedures, respectively. Good visual agreement between dose maps generated by SkinCare and DTS, RadimetricsTM and RDM was obtained. Conclusions: SkinCare is proved to be very convenient solution that can be used for monitoring delivered dose following interventional procedures. © 2021 The Authors.

AB  - Interventional procedures in radiology and cardiology are associated with high dose to the patient. Accurate dosimetry is essential and calibration of the equipment is a means to provide the necessary accuracy of dose assessment. The objective of this work is to investigate the performance of dosimeters used in interventional procedures in different standard and non-standard X-ray radiation qualities, and to investigate potential uncertainties related to dose measurements, thus improving accuracy of patient dosimetry in interventional procedures. Four new reference radiation qualities dedicated to interventional cardiology applications have been established, allowing calibration of dosimeters used in clinical conditions with appropriate traceability to primary standards. Testing of solid-state semiconductor detectors and thermoluminescent dosimeter properties, e.g. influence of photon energy, angle of incidence and dose rate, was performed in the standard and non-standard radiation qualities. Both dosimeter types showed good performance in the non-standard beams during all performance tests. Solid-state dosimeters displayed weak dependence on energy, angle of incidence and dose rate, in the range defined by the manufacturer and requirements of the international standard. Thermoluminescent dosimeters displayed excellent linearity and angular dependence. The influence of energy dependence on measurement uncertainty can be reduced if appropriate radiation quality is selected for calibration. © 2021 Elsevier Ltd

AB  - Medical staff in interventional procedures are among the professionals with the highest occupational doses. Active personal dosemeters (APDs) can help in optimizing the exposure during interventional procedures. However, there can be problems when using APDs during interventional procedures, due to the specific energy and angular distribution of the radiation field and because of the pulsed nature of the radiation. Many parameters like the type of interventional procedure, personal habits and working techniques, protection tools used and X-ray field characteristics influence the occupational exposure and the scattered radiation around the patient. In this paper, we compare the results from three types of APDs with a passive personal dosimetry system while being used in real clinical environment by the interventional staff. The results show that there is a large spread in the ratios of the passive and active devices.

At present, there are many fluoroscopy units without Digital Imaging and Communications in Medicine (DICOM) Radiation Dose Structured Report globally installed. Many of these have not been updated yet, and may never be, therefore, the main objectives of this paper are to develop an offline skin dose mapping application, which uses DICOM headers for the peak skin dose (PSD) assessment and to compare the PSD assessment results to XR-RV3 Gafchromic film for common IC procedures. The mean deviation between the measured and the calculated PSD was 8.7 ± 26.3%. Simulated skin dose map showed good matching with XR-RV3 Gafchromic film. The skin dose mapping application presented in this paper is an elegant solution and a suitable alternative to XR-RV3 Gafchromic film.

AB  - In the absence of information on radiation doses in mammography in the Gulf countries, this study was designed to assess patient dose in terms of entrance surface air kerma and average glandular dose (AGD) in three mammography units in Qatar that covers 21% of all mammography systems in the country. The study of 150 patients involving 600 projections indicated that the average value of AGD in patients was 2.2 mGy for cranio-caudal and 2.5 mGy for mediolateral-oblique views, respectively. Dose assessment was also performed for polymethyl methacrylate phantoms of thicknesses, ranging from 20 to 80 mm. Comparing the patient dose values with several other publications in literature for full-field digital mammography, our values are typically higher, which can be likely attributed to the larger compressed breast thickness.

AB  - The objective of this work is to investigate the possibility to set a national diagnostic reference levels (nDRLs) for diagnostic and screening mammography in Serbia based on local practice and available resources. This study included all types of mammography systems that are currently used in Serbia, namely screen-film mammography (SFM), computed radiography (CR) and full-field digital mammography (FFDM). The nDRLs are provided in terms of mean glandular dose (MGD) for different breast thicknesses simulated by polymethyl methacrylate (PMMA) phantom. For each breast thickness, MGD was calculated for the X-ray tube output, using clinically used exposure parameters. DRLs were chosen as the 75th percentile of MGD distribution for 20-, 40-, 45-, 60- and 70-mm phantom thicknesses. For SFM units proposed nDRL values are 0.7, 2.1, 2.7, 4.6 and 6.8 mGy; for CR units proposed nDRL values are 0.7, 1.8, 2.4, 4.5 and 5.6 mGy; and corresponding values for FFDM units are 0.8, 1.7, 2, 2. and 3.2 mGy for 20-, 40-, 45-, 60- and 70-mm PMMA thickness, respectively.

DRLs were chosen as the 75th percentile of MGD distribution for 20-, 40-, 45-, 60- and 70-mm phantom thicknesses. For SFM units proposed nDRL values are 0.7, 2.1, 2.7, 4.6 and 6.8 mGy; for CR units proposed nDRL values are 0.7, 1.8, 2.4, 4.5 and 5.6 mGy; and corresponding values for FFDM units are 0.8, 1.7, 2, 2. and 3.2 mGy for 20-, 40-, 45-, 60- and 70-mm PMMA thickness, respectively.",

AB  - Growing concern for radiological and nuclear safety and growing use of radiation protection instruments by both professionals and lay persons increase the need for low cost and reliable instrumentation. The aim of this work was to develop a radiation protection instrument that will be both affordable to the widest radiation protection community, including the citizen networks and provide metrologically sound data. The instrument was based on a Geiger-Muller tube, which was tested before and after the energy compensation by lead foils. Instrument energy, angular and dose rate dependence was determined for different tube compensations and the optimum compensation allowing full compliance with relevant standards was identified. © 2019 Elsevier Ltd

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.

Cilj ovog rada je da se razvije aplikacija za mapiranje maksimalne doze kože u interventnim kardiološkim procedurama. Maksimalna doza na površini kože je izračunata pomoću informacija iz DICOM fajlova generisanih nakon kardioloških procedura. Izračunate maksimalne doze su validirane pomoću XR-RV3 Gafchromic filmova koji su postavljeni ispod pacijenta tokom svake procedure. Srednja devijacija između izmerenih i izračunatih maksimalnih doza je 8,7% ± 26,3%. Simulirana dozna mapa pacijenta je pokazala dobro poklapanje sa XR-RV3 Gafchromic filovima. Aplikacija za mapiranje doze kože prikazana u ovom radu je elegantno rešenje i pogodna alternativa za XR-RV3 Gafchromic filmove.
AB  - Interventional Cardiology (IC)procedures are frequently associated with relatively high dose rates and prolonged irradiation times, which often results in very high absorbed skin doses. Objectiveof this work is to develop skin dose mapping application for Peak Skin Dose (PSD) estimation in Interventional Cardiology procedures. PSD was calculated using necessary information from Digital Imaging and Communications in Medicine (DICOM) headers generated after cardiac procedures. Calculated PSDs were validated using XR-RV3 Gafchromic films placed under the patient‘s back during each procedure. The mean deviation between measured and calculated PSD was 8.7% ± 26.3%. Simulated skin dose map showed good matching with XR-RV3 Gafchromic film. Skin dose mapping application presented in this paper is elegant solution and suitable alternative to XR-RV3 Gafchromic film.

AB  - In interventional cardiology (IC), patients may be exposed to high doses to the skin resulting in tissue reactions (skin burns) following single or multiple procedures. To address this issue, online and offline software has been developed to estimate the maximum skin dose (MSD) to the patient from IC procedures. However, the capabilities and accuracy of such skin dose calculation (SDC) software to estimate MSD and 2D dose distributions markedly differ among vendors. Hence, this project focuses onthe harmonisation of RDSR (radiation dose structured report) and on the validation of SDC software products in IC, which will optimise radiation protection of patients. The outcome of the project will include the standards for digital dose reporting, development of protocols for acceptance testing and Quality Control (QC)of SDC software and setting of diagnostic reference levels per clinical complexity, assessing thefrequency of high-dose procedures as well as dose reduction strategies based on the multi-centric data collection. This paper focuses on the work performed to investigate performance of solid state dosimeters used in clinical environment.

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  - 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  - Purpose: The feasibility of setting-up generic, hospital-independent dose alert levels to initiate vigilance on possible skin injuries in interventional procedures was studied for three high-dose procedures (chemoembolization (TACE) of the liver, neuro-embolization (NE) and percutaneous coronary intervention (PCI)) in 9 European countries. Methods: Gafchromic (R) films and thermoluminescent dosimeters (TLD) were used to determine the Maximum Skin Dose (MSD). Correlation of the online dose indicators (fluoroscopy time, kerma- or dose-area product (KAP or DAP) and cumulative air kerma at interventional reference point (K-a,K-r)) with MSD was evaluated and used to establish the alert levels corresponding to a MSD of 2 Gy and 5 Gy. The uncertainties of alert levels in terms of DAP and K-a,K-r, and uncertainty of MSD were calculated. Results: About 20-30% of all MSD values exceeded 2 Gy while only 2-6% exceeded 5 Gy. The correlations suggest that both DAP and K-a,K-r can be used as a dose indicator for alert levels (Pearson correlation coefficient p mostly > 0.8), while fluoroscopy time is not suitable (p mostly < 0.6). Generic alert levels based on DAP (Gy cm(2)) were suggested for MSD of both 2 Gy and 5 Gy (for 5 Gy: TACE 750, PCI 250 and NE 400). The suggested levels are close to the lowest values published in several other studies. The uncertainty of the MSD was estimated to be around 10-15% and of hospital-specific skin dose alert levels about 20-30% (with coverage factor k = 1). Conclusions: The generic alert levels are feasible for some cases but should be used with caution, only as the first approximation, while hospital-specific alert levels are preferred as the final approach.

Conclusions: The generic alert levels are feasible for some cases but should be used with caution, only as the first approximation, while hospital-specific alert levels are preferred as the final approach.",

AB  - This study describes the retrospective lens dose calculation methods developed and applied within the European epidemiological study on radiation-induced lens opacities among interventional cardiologists. While one approach focuses on self-reported data regarding working practice in combination with available procedure-specific eye lens dose values, the second approach focuses on the conversion of the individual whole-body dose to eye lens dose. In contrast with usual dose reconstruction methods within an epidemiological study, a protocol is applied resulting in an individual distribution of possible cumulative lens doses for each recruited cardiologist, rather than a single dose estimate. In this way, the uncertainty in the dose estimate (from measurement uncertainty and variability among cardiologists) is represented for each individual. Eye lens dose and whole-body dose measurements have been performed in clinical practice to validate both methods, and it was concluded that both produce acceptable results in the framework of a dose-risk evaluation study. Optimal results were obtained for the dose to the left eye using procedure-specific lens dose data in combination with information collected on working practice. This method has been applied to 421 interventional cardiologists resulting in a median cumulative eye lens dose of 15.1 cSv for the left eye and 11.4 cSv for the right eye. From the individual cumulative eye lens dose distributions obtained for each cardiologist, maxima up to 9-10 Sv were observed, although with low probability. Since whole-body dose values above the lead apron are available for only a small fraction of the cohort and in many cases not for the entire working career, the second method has only been used to benchmark the results from the first approach. This study succeeded in improving the retrospective calculation of cumulative eye lens doses in the framework of radiation-induced risk assessment of lens opacities, but it remains dependent on self-reported information, which is not always reliable for early years. However, the calculation tools developed can also be used to make an assessment of the eye lens dose in current practice.

AB  - Considering that occupational exposure in medicine is a matter of growing concern, active personal dosimeters (APDs) are also increasingly being used in different fields of application of ionising radiation in medicine. An extensive survey to collect relevant information regarding the use of APDs in medical imaging applications of ionising radiation was organised by the EURADOS (European Radiation Dosimetry Group) Working Group 12. The objective was to collect data about the use of APDs and to identify the basic problems in the use of APDs in hospitals. APDs are most frequently used in interventional radiology and cardiology departments (54%), in nuclear medicine (29%), and in radiotherapy (12%). Most types of APDs use silicon diodes as the detector; however, in many cases their calibration is not given proper attention, as radiation beam qualities in which they are calibrated differ significantly from those in which they are actually used. The survey revealed problems related to the use of APDs, including their reliability in pulsed x-ray fields that are widely used in hospitals. Guidance from regulatory authorities and professional organisations on the testing and calibration of APDs used in hospital would likely improve the situation.

AB  - Interventional cardiac procedures may be associated with high patient doses and therefore require special attention to protect the patients from radiation injuries such as skin erythema, cardiovascular tissue reactions or radiation-induced cancer. In this study, patient exposure data is collected from 13 countries (37 clinics and nearly 50 interventional rooms) and for 10 different procedures. Dose data was collected from a total of 14,922 interventional cardiology procedures. Based on these data European diagnostic reference levels (DRL) for air kerma-area product are suggested for coronary angiography (CA, DRL = 35 Gy cm2), percutaneous coronary intervention (PCI, 85 Gy cm2), transcatheter aortic valve implantation (TAVI, 130 Gy cm2), electrophysiological procedures (12 Gy cm2) and pacemaker implantations. Pacemaker implantations were further divided into single-chamber (2.5 Gy cm2) and dual chamber (3.5 Gy cm2) procedures and implantations of cardiac resynchronization therapy pacemaker (18 Gy cm2). Results show that relatively new techniques such as TAVI and treatment of chronic total occlusion (CTO) often produce relatively high doses, and thus emphasises the need for use of an optimization tool such as DRL to assist in reducing patient exposure. The generic DRL presented here facilitate comparison of patient exposure in interventional cardiology. © 2018 Associazione Italiana di Fisica Medica

AB  - This paper investigates over five decades of work practices in interventional cardiology, with an emphasis on radiation protection. The analysis is based on data from more than 400 cardiologists from various European countries recruited for a EURALOC study and collected in the period from 2014 to 2016. Information on the types of procedures performed and their annual mean number, fluoroscopy time, access site choice, x-ray units and radiation protection means used was collected using an occupational questionnaire. Based on the specific European data, changes in each parameter have been analysed over decades, while country-specific data analysis has allowed us to determine the differences in local practices. In particular, based on the collected data, the typical workload of a European cardiologist working in a haemodynamic room and an electrophysiology room was specified for various types of procedures. The results showed that when working in a haemodynamic room, a transparent ceiling-suspended lead shield or lead glasses are necessary in order to remain below the recommended eye lens dose limit of 20 mSv. Moreover, the analysis revealed that new, more complex cardiac procedures such as chronic total occlusion, valvuloplasty and pulmonary vein isolation for atrial fibrillation ablation might contribute substantially to annual doses, although they are relatively rarely performed. The results revealed that considerable progress has been made in the use of radiation protection tools. While their use in electrophysiology procedures is not generic, the situation in haemodynamic procedures is rather encouraging, as ceiling-suspended shields are used in 90% of cases, while the combination of ceiling shield and lead glasses is noted in more than 40% of the procedures. However, we find that still 7% of haemodynamic procedures are performed without any radiation protection tools.

AB  - The objective of this study was to assess the radiation dose in computed tomography examinations of rabbits using different examination protocols and to correlate these values with the activity of antioxidant enzymes in their red blood cells following irradiation. The presented results revealed that a single, routine computed tomography scan exposure led to a different response of the activity of antioxidant enzymes in red blood cells regarding both dose and time. The results indicate that there is a dose threshold that is about 25 mGy. Doses below that level do not produce any significant changes in the level of antioxidant enzymes activity. On the other hand, the level just above that threshold had a significant impact on the antioxidant defence, but in a relatively short time period (2 hours after exposure), compared to the higher dose that requires a longer adaptive period.

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  - 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.

rezultata pilot monitoringa u interventnoj kardiologiji pomoću namenskih dozimetara
za očno sočivo kalibrisanim u dozimetrijskoj veličini lični dozni ekvivalent Hp(3)., 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.",
