OBJECTIVE.介入放射学倾向于涉及长的程序（即，长的荧光透视时间）。因此，介入放射科医师和工作人员的辐射防护是一个重要的问题。我们使用针孔照相机方法检查和识别介入放射学系统中工作人员接收的散射辐射源。医生和工作人员主要暴露于两种散射辐射源：从患者散射的辐射和来自X射线束准直装置盖的辐射。那些站得离患者和X射线束准直装置近的人，散射辐射较高，辐射剂量较高。因此，在介入放射学过程中的辐射防护是一个重要的问题。
OBJECTIVE. Interventional radiology tends to involve long procedures (i.e., long fluoroscopic times). Therefore, radiation protection for interventional radiology physicians and staff is an important issue. We examine and identify sources of staff-received scattered radiation in an interventional radiology system using a pinhole camera method.CONCLUSION. Physicians and staff are exposed primarily to two sources of scattered radiation: radiation scattered from the patient and radiation from the cover of the x-ray beam collimating device. Those who stand close to the patient and the x-ray beam collimating device, where scattered radiation is higher, have higher radiation doses. Thus, radiation protection during interventional radiology procedures is an important problem.
