Abstract
A radiation shielding laminate includes a layer of a polymeric or copolymeric film; a layer of metal foil; an adhesive in an amount sufficient to bond the metal and the polymeric or copolymeric layers together. A thin metal strip bridging two adjacent laminates is a means by which electricity may flow from one sheet to another and to attach an electrical ground to the layer of metal foil. An optional backing layer may be bonded to the sheet material on the opposite side of the layer of metal foil from the film.
