Along with the flouro-time and distance to X-ray source, protection materials are used to limit X-ray radiation for both operators and staff. Previous studies with different materials have proved a significant reduction on scatter radiation.
The purpose of this study was to evaluate the reduction of scatter radiation before and after using disposable lead-free radiation protection drape composed primarily bismuth (RADPAD®). This is a cross-sectional and descriptive study.
Thirty patients (20 male patients and 10 female patients), who had indications for coronary angiography/ angioplasty, were enrolled into the study. Radial artery access was performed on 93.33% of cases. Scatter radiation before and after protection with RADPAD® are respectively 252.27±443.44 và 19.53±18.04 (microGy) (p<0.001). Skin dose (mGy) and area dose (microGym2) are respectively 508.47±376.20 and 3270.14±2454.85 (p<0.001) and flouro-time is 10.01±6.6 (second). The reduction of scatter radiation after protection with RADPAD is 92.26%.

Scatter radiation is a main X-ray source that operators and staff have to work and expose with during procedure. Sterilized disposable lead-free radiation protection drape (RADPAD®) significantly reduces scatter radiation up to 92.26% during X-ray guided coronary angiography/ angioplasty procedures. Hence, it helps to protect doctors and staff from radiation in cathlab.
