[Reduction of radiation exposure by protective measures in heart catheter studies and interventional cardiology]

To estimate scatter radiation exposure of physicians and radiologic assistants, phantom measurements were made in different projections during coronary angiography and angioplasty. Scatter radiation was reduced by using a protective glass (1.5 mm) and a shield (1.25 mm) for physicians under the range of 5%, and for radiologic assistants by using a second set of a glass and a shield (1.0 mm) under the range of 10%. We therefore urge the recommendation of installing such protective equipment in order to lower scatter radiation.
