In plain language
In neurointerventional angiography on one modern system, per-procedure doses were measured for interventional radiologists, nurses and technologists. Eye lens doses were similar for all three roles, with nurses slightly highest, while the interventional radiologist had the highest extremity and whole-body doses.

What it found
Per-procedure eye lens doses were similar across roles, with the nurse slightly higher than the interventional radiologist.
Key figures: 18.7, 19.7, and 13.4 µSv (IR, nurse, technologist)
Extremity dose per procedure was highest for the interventional radiologist.
Key figures: 54.7 µSv interventional radiology (IR); 15.3 µSv nurse; 14.2 µSv technologist
Whole-body effective dose per examination was highest for the interventional radiologist, followed by the technologist and nurse.
Key figures: 12.6, 7.1, and 10.0 µSv (IR, nurse, technologist)
Patient dose was higher for cerebral than carotid procedures, and higher for therapeutic than diagnostic procedures.
Key figures: Cerebral mean dose-area product (DAP) 73/143 Gy cm2, cumulative air kerma (CAK) 657/1,888 mGy; carotid DAP 40/79 Gy cm2, CAK 487/679 mGy
Patient effective doses estimated from DAP.
Key figures: 4.04/8.16 mSv cerebral; 2.11/3.93 mSv carotid (diagnostic/therapeutic)
Limits to keep in mind
Single fluoroscopy system with a small staff-dose sample (38 examinations), and eye and extremity doses were inferred from collar and body dosimeters rather than dedicated eye or ring dosimeters as far as the abstract states. Country and shielding use are not reported in the abstract.
