The radiation exposure of the medical team involved in 35 consecutive cardiac catheterisation procedures performed at the Istituto di Malattie dell'Apparato Cardiovascolare, University of Bologna, was calculated. A mapping of the iso-exposure lines and the values of radiation exposure of each component of the team were determined for each procedure. With these parameters the total amount of radiation for a normal diagnostic activity coul be calculated. The mean values obtained (150-250 mR/week) were in the range of the maximal values permitted to medical teams professionally exposed to the risk of radiation (3R/13 weeks). Rotation of the components of the team granted a continuing diagnostic activity within the limits of radiation exposure imposed by the law. An evaluation of the different procedures and techniques indicated coronary arteriography as the procedure with a higher risk of radiation (M = 50 mR/procedure) and pointed out the mechanism involved in order to obtain a considerable reduction of radiation exposure.
计算了参与博洛尼亚大学心血管疾病研究所连续进行的35例心脏导管插入术的医疗团队的辐射暴露量。针对每例手术，确定了等暴露线的分布图以及团队各成员的辐射暴露值。利用这些参数，可以计算出正常诊断活动的总辐射量。获得的平均值（150 - 250 mR/周）处于专业暴露于辐射风险的医疗团队允许的最大值范围内（3R/13周）。团队成员的轮换使得在法律规定的辐射暴露限度内能够持续进行诊断活动。对不同手术和技术的评估表明，冠状动脉造影术是辐射风险较高的手术（M = 50 mR/例），并指出了相关机制以大幅降低辐射暴露。
