Material samples for tests are prepared by cutting out small 2 1/2” circular discs of Drape Armour™ material and evaluated by comparing the fractional amounts of radiation transmitted through each sample and varying thickness of lead. The source of radiation is a diagnostic X-ray tube energized by a high frequency generator. The fractional amounts of transmitted radiation are recorded using both film and an ionization chamber. Both the accelerating potential and X-ray beam half-value layers are actively monitored to maintain precise consistency between samples and test sessions. The amount of exposure is adjusted to yield an optical density within the linear response range of the film. Attenuation measurement tests were performed at a range of 60-120 kVp.*

Three Important Factors to Help Reduce Exposure to Scatter Radiation:
Keep clinicians as far from the radiation source as possible. The intensity and dose of radiation decrease as distance from the source increases.
Block as much scatter radiation from the clinician’s skin and vital organs as possible. While many institutions use lead aprons, glasses and gloves to help block radiation, Drape Armour near the radiation source provides critical protection and helps ensure radiation exposure is as low as is reasonably achievable.
Clinicians exposed to the harmful effects of scatter radiation.
Drape Armour and Drape Armour LOW free positional shields are designed to protect at the procedure site where scatter radiation is most prevalent. These shields can help to protect surgeons and other members of the clinical staff, and offer substantial attenuation as demonstrated by direct beam studies.
