Eurados 2016 intercomparison exercise of Eye Lens dosemeters
Radiation Protection Dosimetry, 2018Co-Authors: Isabelle Clairand, Mercè Ginjaume, E. Carinou, J. Domienik-andrzejewska, R. Behrens, M. Brodecki, O. Hupe, M RoigAbstract:In the context of a new annual Eye Lens dose limit for occupational exposure equal to 20mSv, European Radiation Dosimetry Group (EURADOS) organized an intercomparison dedicated to Eye Lens dosemeters, including photon and beta radiations. The objective was to complete the first intercomparison recently organized by EURADOS for photons and to update the overview of Eye Lens dosemeters available in Europe. The dosemeters provided by the 22 participants coming from 12 countries were all composed of thermoluminescent detectors. The dosemeters were irradiated with photon and beta fields defined in relevant standards. The results, provided by participants in terms of Hp(3), were compared to the reference delivered doses. Results are globally satisfactory for photons since 90% of the data are in accordance to the ISO 14146 standard requirements. The respective values for betas stress the fact that dosemeters designed for Hp(0.07) are not suitable to monitor the Eye Lens dose in case of betas. © The Author(s) 2018.

Radiation-Induced Lens Opacities among Interventional Cardiologists Retrospective Assessment of Cumulative Eye Lens Doses
Radiation Research, 2018Co-Authors: L. Struelens, J. Farah, J. Dabin, E. Carinou, P. Askounis, O. Ciraj-bjelac, J. Domienik-andrzejewska, D. Berus, R. Padovani, P. CovensAbstract: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. © 2018 by Radiation Research Society.

Occupational Exposure of the Eye Lens in Interventional Procedures: How to Assess and Manage Radiation Dose.
Journal of the American College of Radiology : JACR, 2016Co-Authors: O. Ciraj-bjelac, E. Carinou, Paolo Ferrari, Marta Sans Merce, Merce Gingaume, Una O’connorAbstract:Occupational exposure from interventional x-ray procedures is one of the areas 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 objective of this work is to review Eye Lens dose levels in clinical practice that may occur from the use of ionizing radiation. The use of a dedicated Eye Lens dosimeter is the recommended methodology; however, in practice it cannot always be easily implemented. Alternatively, the Eye Lens dose could be assessed from measurements of other dosimetric quantities or other indirect parameters, such as patient dose. The practical implementation of monitoring Eye Lens doses and the use of adequate protective equipment still remains a challenge. The use of lead glasses with a good fit to the face, appropriate lateral coverage, and/or ceiling-suspended screens is recommended in workplaces with potential high Eye Lens doses.

Validation measurements for the retrospective calculation of Eye Lens doses of interventional cardiologists
Physica Medica, 2016Co-Authors: E. Carinou, J Domienik, J. Farah, J. Dabin, P. Askounis, O. Ciraj-bjelac, D. Berus, P. Covens, Isabelle Clairand, Joanna JurewiczAbstract:Introduction The Eye Lens radiation-induced risk has been assessed for various population groups. In the framework of the European epidemiological study, EURALOC, an attempt is made to determine a possible dose-response relationship by targeting interventional cardiologists, a group of high exposure values. Purpose In the study, Eye Lens doses are assessed using two approaches: combining self-reported data on working practices and Eye Lens doses from literature (approach 1); and converting the whole-body dose values to Eye Lens doses (approach 2). Eye Lens dose measurements are performed to validate both approaches and to determine their associated uncertainties. Materials and methods Eye Lens dose measurements are performed on cardiologists in routine practice using commercially available dedicated Eye Lens dosemeters. Furthermore, whole-body dose values are obtained from whole-body dosemeters worn above the lead apron at the chest left position. Exposure information including tube orientation, operator position and orientation are collected. Results The first values of Eye Lens doses measured in routine clinical conditions are in good agreement with Eye Lens dose estimates obtained with the two approaches No systematic errors have been found which is encouraging in order to continue using either of the two approaches for the estimation of Eye Lens doses and the final benchmarking against Lens opacities. Conclusion Preliminary measurements in clinical conditions validate the two suggested complementary dosimetric methodologies: the first, based on self-reported occupational history while the second, starts from personal whole body doses to determine the Eye Lens dose.

Operator’s Eye Lens dose in computed tomography–guided interventions
European Radiology, 2020Co-Authors: Siru Kaartinen, Minna Husso, Hanna MatikkaAbstract:Objectives To survey (1) operator’s Eye Lens doses in typical computed tomography (CT)-guided interventions, (2) correlation between dose length product (DLP) and the operator’s dose, and (3) different ways for estimating the Eye Lens dose in clinical settings. Methods Doses of 16 radiologists in 164 CT-guided interventional procedures were prospectively measured during a 6-month time period upon radioprotective garments and descriptive statistical outcomes were calculated. The correlations between DLP and measured doses were survEyed. Results On average, the operator’s dose at the Eye level (DEL, H_p(0.07)) was 22 μSv per procedure and the personal equivalent dose H_p(10) at the collar level was 21 μSv per procedure. The mean DLP of a procedure was 320 mGy cm, where 54% resulted from the fluoroscopy, the mean exposure time being 18 s. Based on the results, the operator’s DEL could be estimated from DLP using the equation DEL (μSv) = 0.10 μSv/mGy cm × patient fluoro DLP (mGycm) ( p < 0.001), and the dose at the collar level (DCL) using the equation DCL (μSv) = 0.12 μSv/mGy cm × patient fluoro DLP (mGy cm) ( p < 0.001). In addition, DEL (μSv) = 0.7 × DCL (μSv). Conclusions The Eye Lens doses in CT-guided interventions are generally low even without protective equipment, and it is unlikely that the recommended annual equivalent dose limit of 20 mSv for the Lens of the Eye will be exceeded by conducting CT-guided interventions solely. Eye Lens dose can be roughly estimated based on either DLP of the procedure or dose measured at the operator’s collar level. Key Points • Eye Lens doses in CT-guided operations are generally low. • It is unlikely that the ICRP recommendation of the yearly equivalent dose limit of 20 mSv will be exceeded by conducting CT-guided interventions solely. • Magnitude of Eye Lens dose can be estimated based on either DLP of the procedure or dose measured at the operator’s collar level.

Influence of dosemeter position for the assessment of Eye Lens dose during interventional cardiology
Radiation Protection Dosimetry, 2015Co-Authors: Sara Principi, Maria A. Duch, Roberto M. Sánchez, Mercè Ginjaume, Eliseo VanoAbstract:The equivalent dose limit for the Eye Lens for occupational exposure recommended by the ICRP has been reduced to 20 mSv y−1 averaged over defined periods of 5 y, with no single year exceeding 50 mSv. The compliance with this new requirement could not be easy in some workplace such as interventional radiology and cardiology. The aim of this study is to evaluate different possible approaches in order to have a good estimate of the Eye Lens dose during interventional procedures. Measurements were performed with an X-ray system Philips Allura FD-10, using a PMMA phantom to simulate the patient scattered radiation and a Rando phantom to simulate the cardiologist. Thermoluminescence (TL) whole-body and TL Eye Lens dosemeters together with Philips DoseAware active dosemeters were located on different positions of the Rando phantom to estimate the Eye Lens dose in typical cardiology procedures. The results show that, for the studied conditions, any of the analysed dosemeter positions are suitable for Eye Lens dose assessment. However, the centre of the thyroid collar and the left ear position provide a better estimate. Furthermore, in practice, improper use of the ceiling-suspended screen can produce partial protection of some parts of the body, and thus large differences between the measured doses and the actual exposure of the Eye could arise if the dosemeter is not situated close to the Eye.

Eye Lens exposure to radiation in interventional suites caution is warranted
Radiology, 2008Co-Authors: Eliseo Vano, L Gonzalez, Jose M Fernandez, Ziv J HaskalAbstract:Purpose: To report estimated radiation doses to the Eye Lens of the interventionalist from procedures performed with and without use of radiation protection measures. Materials and Methods: Scattered radiation doses for seven interventional radiology fluoroscopic systems were measured by using phantoms simulating patients 16–28 cm in thickness undergoing low-, medium-, and high-mode fluoroscopy, cine cardiac imaging, and digital subtraction angiography (DSA). The radiation doses to the Eye Lens in low- and high-dose scenarios were estimated. Beam angulation, biplanar equipment, working distance, procedure complexity, imaging collimation, and use of Eyeglasses and/or protective suspended screens were taken into account. The doses to the Lens in several procedures were assessed. Results: Mean scattered radiation doses to the Lens during fluoroscopy were 6.0 and 34.5 μSv/min in the low- and high-dose scenarios, respectively. For DSA, typical doses to the Lens ranged from 0.77 to 3.33 μSv per image. Operation...

OPTIMIZATION OF A RADIOPHOTOLUMINESCENT GLASS DOSEMETER FOR OCCUPATIONAL Eye Lens DOSIMETRY IN INTERVENTIONAL RADIOLOGY/CARDIOLOGY.
Radiation protection dosimetry, 2018Co-Authors: Edilaine Honorio Da Silva, P. Covens, Lara Struelens, F. Vanhavere, Satoshi Ueno, Yasuhiro Koguchi, Nico BulsAbstract:Hospital based workers that perform interventional radiology are at risk of reaching the Eye Lens dose limit of 20 mSv/y. These workers are exposed to the radiation scattered by the patient, which creates a complex field, with low radiation energy reaching the Eyes of the medical staff from wide angles. Therefore, the dosemeter used in the assessment of the Eye Lens dose of interventional radiologists needs to respond accurately in such conditions. In this study, the angular response of a commercially available radiophotoluminescent glass dosemeter, GD-352M, was optimized via Monte Carlo simulations, aiming at its use as Eye Lens dosemeter in interventional radiology. The improved dosemeter was manufactured and then characterized in terms of Hp(3), the quantity recommended for Eye Lens dosimetry. Its response was compared to the IEC 62387:2012 requirements for Hp(3) and to requirements proposed specifically for Eye Lens dosemeters used in interventional radiology. The improved dosemeter meets the IEC 62387:2012 requirements for energy and angular response for Hp(3) and also shows good agreement with the more strict requisites proposed for Eye Lens dosemeters to be used in interventional radiology.

Track, calculate and optimise Eye Lens doses of interventional cardiologists using mEyeDose and mEyeDose_X.
Journal of radiological protection : official journal of the Society for Radiological Protection, 2018Co-Authors: P. Covens, J. Dabin, O. De Troyer, Octavian Dragusin, Jan Maushagen, Lara StruelensAbstract:The European epidemiological study EURALOC aimed to establish a dose response relationship for low dose radiation induced Eye Lens opacities using interventional cardiologists as the study group. Within the EURALOC project, two dosimetry methodologies were developed serving as the basis for cumulative Eye Lens dose assessment. Besides being the cornerstone of the epidemiological part of the project, these dosimetry methodologies were also used to develop two calculation tools, 'mEyeDose' and 'mEyeDose_X' which enable to track, calculate, optimise and analyse Eye Lens doses in interventional cardiology. mEyeDose was developed as a Mobile Web App and serves as a readily accessible, highly didactic educational tool for interventional cardiologists whereas the user-friendly desktop application mEyeDose_X is designed for radiation protection professionals. Both tools are freely available and can be used for a wide range of purposes such as optimisation of working practices, calculation of cumulative Eye Lens doses or risk assessment prior to routine Eye Lens dose monitoring.
