Eye lens monitoring for interventional radiology personnel: dosemeters, calibration and practical aspects of H-p(3) monitoring. A 2015 review

摘要: A thorough literature review about the current situation on implementation of eye lens monitoring has been performed in order to provide recommendations regarding dosemeter types, calibration procedures and practical aspects for interventional radiology personnel. Most relevant data from 100 papers have analysed classified following topics: challenges today monitoring; conversion coefficients, phantoms dose evaluation; correction factors dosemeters measurements; position influence protective devices. The major findings can be summarised as follows: recommended operational quantity is H p (3). At present, several are available being developed. However, practice, very often, alternative methods used assess lens. summary found assessment provided. These give an estimation when methods, such use a whole body dosemeter, used. wide range values found, thus indicating large uncertainty associated with these simplified methods. Reduction most common devices obtained experimentally using Monte Carlo calculations presented. paper concludes that placed at collar level outside lead apron useful first estimate exposure. workplaces estimated annual equivalent close limit, specific should performed. Finally, training involved medical staff risks ionising radiation correct systems strongly recommended.
