Abstract
An evaluation was performed to determine the distribution of radiation dose received by vascular/interventional radiologists, henceforth culled radiologists, to their hands and arms during inteventional radiology procedures. During 87 patient procedures, measurements were made using thermoluminescent dosimeters to determine the distribution of dose to the hands and forearms. Measurements were made on a finger, the palm, wrist, elbow, and the mid-humerus of both hands and arms. Results suggested a non-uniformity of dose with the maximum dose being measured on the left hypothenar (fleshy side of the palm). The left hand receives a higher dose than the right hand due to positioning of the radiologist with respect to the patient.
