“…Contrary to the whole body dosimetry, eye lens dosimetry is not currently well established and numerous studies were carried out to investigate various aspects of eye dosimetry, such as the development of new dedicated eye dosemeters and calibration procedures [10,12,[26][27][28][29][30]. Furthermore, clinical studies have been conducted to discuss the methodology of the assessment of the eye lens dose levels, to investigate the monitoring arrangements using different types of dosemeters, to study correlations of eye lens dose with patient dose indices and to perform retrospective eye lens dose assessment [17,18,20,22,26].…”

“…Generally they employ a thermoluminescent chip as passive dosemeter and some material covering it to mimic the necessary thickness to assure the coherence with the respective quantity definition [30,[32][33][34]. All these new devices should conform to suitable calibration procedures and type tests [29]. When a specific dosemeter is not available, Hp(3) can be estimated through dosemeters calibrated in terms of Hp (10) and Hp(0.07) through proper correction factors, [6,28,35].…”

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.

In the framework of the ORAMED project (Optimization of RAdiation protection for MEDical staff), funded by the European Union Seventh Framework Programme, different studies were aimed at improving the quality of radiation protection in interventional radiology and nuclear medicine. The main results of the project were presented during a final workshop held in Barcelona in January 2011, the proceedings of which are available in the open literature. One of the ORAMED tasks was focused on the problem of eye-lens photon exposure of the medical staff, a topic that gained more importance especially after the ICRP decision to lower the limiting equivalent dose to 20 mSv per year. The present technical note has the scope, besides briefly summarising the physical reasons of the proposal and the practical implications, to provide, in tabular form, a set of air kerma to Hp(3) conversion coefficients based on the adoption of a theoretical cylindrical model that is well suited for reproduction of the mass and the shape of a human head.

-Mainly due to the ICRP recommendation to decrease the exposure limit for eye lenses, the eye lens dosimetry has to be reconsidered. This paper gives an overview of the issues raised after this recommendation; that is to say, the choice and definition of the operational quantity to be monitored, the type testing and calibration of dosimeters aimed at measuring eyes lens "doses", the design of existing eye lens dosimeters and their wearing conditions. Finally, a criterion to choose between a direct measurement of the personal dose equivalent at three millimeters depth, H p (3), with a dedicated dosimeter, and an indirect evaluation of H p (3) through whole-body monitoring is presented.
