1. A flexible, surface-covering, radiation shielding laminate comprising:
- (a) a layer of one of a polymeric or copolymeric film;
(b) a layer of electrically conducting foil having two sides;
(c) a scratch resistant coating bonded to one of said sides of said foil;
(d) an adhesive layer bonding the film to one of said sides of the foil; and
(e) an electrical ground attached to the layer of metal foil.

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.

11. A process for providing electromagnetic radiation shielding for an object, said process comprising the steps of:
-
(a) preparing a flexible, surface-covering laminate, comprising; (1) forming a layer of one of a polymeric or copolymeric film; (2) forming a layer of metal foil having two sides; (3) applying a scratch resistant coating to at least one side of the foil; and (4) bonding the layers together with an adhesive; (b) covering the surface of the object with the formed laminate; and (c) attaching an electrical ground to the layer of metal foil, whereby electromagnetic radiation is retarded from passing through the laminate. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
