Abstract
A multi-ply sheet having a center ply support matrix in which the radio opaque compound barium sulfate is distributed as a powder and is supported by the matrix. The barium sulfate is present in an amount sufficient to block scatter radiation produced by the medical radiology procedures. A base ply of a thin liquid impervious polyethylene material is fastened to one side of the support matrix ply. A third ply is composed of a typical absorptive surgical drape material and is fastened to the other side of the support matrix ply.
