It's about protecting your Hands, Arms & Your Eyes . . .
Scatter Radiation is a Clinician's worst enemy. Its directly linked to long term health problems and a serious long term health risk. The closer you are to the primary beam, the more you are at risk. The National & International Conferences on Radiation Protection (ICRP/NCRP) have set recommended standards. “Lens/Eye Dose should be limited to 15 RADs per year.” (ICRP/NCRP) They have also concluded that, “Cataracts occur with cumulative dose between 200 to 500 RADs.” (ICRP/NCRP). Based on an average Lens/ Eye Dose of .062 Rads per hour, shown left and an average of 576 hours of Fluoroscopy per year some clinicians are receiving doses of 35.7 RADs per year.
Conventional Radiation Protection Strategies, including Leaded Glasses yield an approximate dose reduction of 45%. This is not enough.
A recent study has drawn this conclusion,
"leaded glasses or scatter shielding drapes substantially reduced lens dose by factors of 9.5 and 12 respectively. Maximal eye shielding was achieved by the use of both leaded glasses and scatter-shielding drapes"

Size Does Matter...
Positioning is critical to the effectiveness of a Sterile Radiation Protection Drape. Positioned properly to block scatter radiation coming from the patients body, these Sterile Radiation Shields can be highly effective. Positioned improperly they are much less effective. And size is important because larger drapes provide better coverage of the scattered radiation field, absorb a greater amount of scattered radiation coming off the patients body and provide a greater margin for error for critical positioning.
