Abstract
The International Commission on Radiological Protection (ICRP) revised a drastic decrease of the annual eye equivalent dose limit. The present study aimed to evaluate the amounts of radiation to which the eye lenses of radiological technologists (RT) become exposed and the effects of wearing lead glasses on dose reduction while assisting patients during radiographic assessments. Lens equivalent doses (Hp(3)) were measured at the neck using personal dosemeter. In addition, Hp(3) was estimated by converting air kerma determined using small optically stimulated luminescence (OSL) dosemeters at six positions on lead glasses near the eyes and at the neck. The estimated mean Hp(3) from personal dosemeter at the neck varied from 3.92 to 18.6 mSv/y. Compare to OSL for which the dose varies from 8.95 to 54.75 mSv/y, personal dosimeter underestimate Hp(3).Therefore, Hp(3) for RT might exceed the revised eye equivalent dose limit 20 mSv/y recommended by the ICRP.
