[Effective dose evaluation of angiography staff].

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.
