Physician Radiation Exposure During Radial Access Cardiac Catheterization Using a RAD Board

Radiation exposure to operator is an occupational hazard of invasive cardiologists. During radial access for diagnostic catheterization, a new radio-dense arm board is advertised to reduce operator radiation exposure. The investigators randomize patients to a new radio-dense armboard versus a standard radio-transparent armboard during diagnostic catheterization and measure radiation exposure to the operator. Both groups have a radio-dense pelvic shield in place. The investigators hypothesize that operator radiation dose will be decreased by use of the radio-dense armboard.
