Occupational Radiation Dose, Especially for Eye Lens: Hp(3), in Medical Staff Members Involved in Computed Tomography Examinations

Radiation dose management of medical staff has become increasingly important. Particularly, based on the statement by International Commission Radiological Protection (ICRP) in 2011, a new lower equivalent limit for eye lens is being established each country. Although many reports have discussed occupational radiation interventional radiology (IR), few studies examined during computed tomography (CT) examinations. This study investigated exposure to present CT room irradiation, with particular focus lens. The those who assist patients head, chest and upper abdomen examination was measured phantom study. scattered never negligible (i.e., high); Hp(3) highest head examination, at 0.44 mSv per examination. Furthermore, shielding effect protection glasses large, are useful tools involved justification optimisation should be carefully considered assistant actions.
