The Directive lowers the limit on equivalent doses to the eye lens from 150 mSv to 20 mSv per year, according to the publication 103 of ICRP. The aim of this work is to evaluate the current status of the eye lens radiation exposure in an Interventional Radiology Department depending on the position of the specific dosimeters used by exposed workers, to compare the measured doses with the limit imposed by the Directive. Methods: the equivalent dose was assessed, over a period of 30 days, using four specific Hp dosimeters (Ainsbury E. A. et al., Mutat. Res./Rev. Mutat. Res., 770, Part B (2016) 238), placed in four different points on a personal protective device. For each dosimeter we evaluated the equivalent dose absorbed and we compared these doses with the new limits of the 2013/59 EURATOM Directive. 1. – Introduction Nowadays, the use of ionizing radiations is increasing in the health context, both for diagnostic activities and for therapy activities. However, ionizing radiation is harmful to the body, therefore it was necessary to recommend a radiological protection system, both for patients and for doctors and for all the staff exposed to radiation. Focusing our attention on exposed medical workers, the limit on the equivalent dose to the lens for ( ∗ ) Corresponding author.
