Estimating brain radiation dose to the main operator in interventional radiology.

The aim of this study was to estimate brain radiation dose to the main operator during interventional radiology procedures. Occupational brain doses from 19 interventional procedures were measured using thermoluminiscent dosimeters and an anthropomorphic RANDO woman phantom simulating a main operator. Results show that, interventional radiologists may receive minimum and maximum brain doses per procedure of 0.
