title: DOSE MEASUREMENTS TO THE LENS IN NUCLEAR MEDICINE AND IN FLUOROSCOPY-GUIDED INTERVENTIONAL PROCEDURES: ANALYSIS OF THE RESULTS AND ASSESSMENT OF THE EFFECTIVENESS OF PROTECTIVE EYEWEAR ANTI-X.
abstract: The new limit of 20 mSv to the lens raises the need for further assessment of the equivalent dose to the lens for nuclear medicine and interventional radiology operators. (a) A measurement campaign was performed in nuclear medicine, (b) a routine monitoring was organised in interventional procedures and (c) the effectiveness of protective eyewear was assessed. In nuclear medicine, for photon fields, the adequacy of Hp(0.07) of dosemeter worn on the trunk is confirmed; with (90)Y, the annual values of Hp(3) measured in therapeutic session are <5 mSv. In interventional procedures, routine monitoring of the dose to the lens must be maintained where the values of Hp(0.07) dosemeter worn on the trunk are higher than one-third of the new limits. The measures carried out have shown that the attenuation factor mean of the protective glasses is equal to ∼4 (range 1.7-11.4).
