Impact of Ceiling Suspended Shield Size on Primary Operator Radiation Dose During Coronary Angiography and Intervention

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that
