Shielding effectiveness of X-ray protective garment

Purpose Certification of the X-ray shielding garment is based on attenuation testing flat material samples. We investigated difference effectiveness compared to realistic use when worn body a staff person. Methods Attenuation factors protective aprons have been evaluated for several clinical scenarios with Monte Carlo (MC) calculations ICRP female reference model and an experimental setup. The MC calculated refer effective dose E, whereas measured personal equivalent Hp(10). calculated/measured were identical materials under conditions standard IEC 61331-1 that currently in type aprons. Results As result, example, at common tube voltage 80 kV, real 0.35 mm Pb apron by 3-dimensional 38% 76% higher than MC-calculated organ doses show maximum contribution E being within operatoŕs abdomen/pelvis region. Conclusions With our findings, garments could be improved effectiveness.
