The present study is focused on the personnel doses during several types of interventional radiology procedures. Apart from the use of the official whole body dosemeters (thermoluminescence dosemeter type), measurements were performed to the extremities and the eyes using thermoluminescent loose pellets. The mean doses per kerma area product were calculated for the monitored anatomic regions and for the most frequent types of procedures. Higher dose values were measured during therapeutic procedures, especially embolisations. The maximum recorded doses during a single procedure were 1.8 mSv to the finger (nephrostomy), 2.1 mSv to the wrist (liver chemoembolisation), 0.6 mSv to the leg (brain embolisation) and 2.4 mSv to the eye (brain embolisation). The annual doses estimated for the operator with the highest workload according to the measurements and the system's log book were 90.4 mSv to the finger, 107.9 mSv to the wrist, 21.6 mSv to the leg and 49.3 mSv to the eye. Finally, the effect of the beam angulation (i.e. projection) and shielding equipment on the personnel doses was evaluated. The measurements were performed within the framework of the ORAMED (Optimization of RAdiation Protection for MEDical staff) project.
本研究聚焦于几种类型的介入放射学程序中的人员剂量。除了使用官方的全身剂量计（热释光剂量计类型）外，还使用热释光散粒对四肢和眼睛进行了测量。针对监测的解剖区域和最常见的程序类型计算了每比释动能面积乘积的平均剂量。在治疗程序中，尤其是栓塞过程中，测量到的剂量值更高。单次程序中记录的最大剂量为手指（肾造瘘术）1.8毫希沃特、手腕（肝化疗栓塞）2.1毫希沃特、腿部（脑栓塞）0.6毫希沃特和眼睛（脑栓塞）2.4毫希沃特。根据测量结果和系统日志估算的工作量最大的操作员的年剂量为手指90.4毫希沃特、手腕107.9毫希沃特、腿部21.6毫希沃特和眼睛49.3毫希沃特。最后，评估了射束角度（即投影）和屏蔽设备对人员剂量的影响。这些测量是在ORAMED（医务人员辐射防护优化）项目的框架内进行的。
