Radiation exposure to the angiographer was measured using thermoluminescent dosimeters (TLD), commercial film badges, and appropriate ionization survey meters. Data were collected during 47 coronary artery examinations with the lead overleaf. During a single coronary examination, the angiographer receives 0.9 mR to the lens and 2.8 mR to the hand. The calculated yearly exposure to the angiographer performing 10 examinations per week is 450 mR to the lens, 9% of the maximum permissible dose (MPD), and 1400 mR to the hand, 2% of the MPD. Exposure rates for the left anterior oblique (LAD) and right anterior oblique (RAO) projections during cine and fluoroscopy were taken at the position occupied by the angiographer. Scatter radiation is 5-10 times greater in the LAO projection. The second trial was monitored during 18 coronary artery examinations minus the lead overleaf. A significant decrease in radiation exposure was accomplished through the use of the lead overleaf.
使用热释光剂量计（TLD）、商用胶片剂量计和合适的电离测量仪来测量血管造影技师所接受的辐射剂量。在47例冠状动脉检查过程中，使用了铅防护帘，并收集了相关数据。在单次冠状动脉检查中，血管造影技师的晶状体接受0.9毫伦琴的辐射，手部接受2.8毫伦琴的辐射。计算得出，每周进行10次检查的血管造影技师每年的辐射暴露量为：晶状体450毫伦琴，占最大允许剂量（MPD）的9%；手部1400毫伦琴，占MPD的2%。在电影摄影和荧光透视期间，在血管造影技师所处位置测量左前斜位（LAD）和右前斜位（RAO）投照时的辐射暴露率。左前斜位投照时的散射辐射比右前斜位大5至10倍。在18例冠状动脉检查中，减去铅防护帘进行了第二项试验监测。使用铅防护帘显著降低了辐射暴露。
