The effective doses received by staff members involved in angiographic examinations were determined using data compiled on radiation doses obtained from monitoring personnel and phantom measurements. Thermoluminescence personnel monitors were used to evaluate the personal doses received by the staff during radiological procedures. Organ or tissue doses were determined by using phantom measurements in which a RANDO-woman phantom was used to simulate geometric conditions during actual angiographic examinations. The annual effective dosage received by radiologists was estimated to be 8 to 9 mSv per year when they wore a lead-rubber protector. When this protector was disregarded, their annual effective doses frequently went beyond the annual limit of 50 mSv. The surface dose to the female abdomen per ten months was estimated as 1.7 mSv. Thus, care should be taken by women staff members.
参与血管造影检查的工作人员所接受的有效剂量，是利用从监测人员和体模测量获得的辐射剂量数据来确定的。热释光个人剂量计用于评估工作人员在放射程序期间所接受的个人剂量。器官或组织剂量是通过体模测量来确定的，其中使用RANDO女性体模来模拟实际血管造影检查期间的几何条件。当放射科医生佩戴铅橡胶防护器时，估计他们每年接受的有效剂量为8至9毫希沃特。当不考虑这种防护器时，他们的年度有效剂量经常超过50毫希沃特的年度限值。估计女性腹部每十个月的表面剂量为1.7毫希沃特。因此，女性工作人员应予以注意。
