Zero-cost Radiation Protection Method to Reduce Radiation Exposure of Interventional Cardiologists During Transradial Percutaneous Coronary Procedures (FREEPADRAD Trial)

The intervention involves the application of a triple-layer lead apron to the patient's lower abdominal and pelvic region during transradial coronary procedures. The apron measures 75 cm × 45 cm and is composed of three layers of 0.25 mm Pb-equivalent material. This protective shield is placed on the patient in addition to standard operator radiation protection measures. The primary goal of this intervention is to reduce scatter radiation exposure to the operator, thereby improving occupational safety in the catheterization laboratory. This approach leverages existing radiation protection materials in a novel configuration.
