Abstract: A radiation shield includes an aperture connected to an edge of the shield by a slit, which is held closed by a releasable flap. Instrumentation can be inserted through the aperture to contact a patient over which the shield is draped. By releasing the flap and thereby opening the aperture toward the edge of the shield, the shield can be removed from the patient without removing the instrumentation inserted through the aperture. A secondary shield is releasably secured over the aperture, affording further protection. Because the shield is placed within the septic field during use, the shield includes a sterilizable outer covering.
