Hp(3) vs TLD-100 for eye lens dosimetry in interventional radiology procedures: a preliminary study

Abstract Following the 2013/59/EURATOM Directive, Italian 101/2020 Decree Law lowered annual limit on equivalent dose to eye lens from 150 20 mSv for exposed workers, in order risk of radiation-induced cataract. Such a drastic reduction makes it very important perform accurate monitoring medical staff that works with ionizing radiation as interventional radiologists and cardiologists. The standard occupational dosimetry consists into Hp(3) calibrated dosimeters placed physicians glasses, next eyes. However, this system suffers calibration issues, therefore, is usually extrapolated extremity or whole body measurements, leading low accuracy. Chips thermoluminescent TLD-100 dedicated were over plexiglas (PMMA) phantom measure Entrance Surface Air Kerma ( K e ) H physician, respectively, during simulated radiology procedures. Values all below regulatory limit. Our results show TLD-100’s response seems be correlated according relationship = F × , an average factor 3.9 mGy/mSv, opening possibility using both protection workers.
