Abstract
A radiation shield comprises a substrate polymer layer, a conductive layer having an aperture providing access to a front face of a cellular telephone, adjacent the substrate polymer layer, and an adhesion surface adjacent the conductive layer and the front face. A radiation shield comprising a first substrate polymer layer, a conductive layer having an aperture providing access to a touch-sensitive screen of the front face, adjacent the first substrate polymer layer, a second substrate polymer layer adjacent the conductive layer, and an adhesion surface adjacent the conductive layer and the front face. At least one opening provides access to the front face.
Claims5
A method for reducing an electromagnetic radiation level produced by a cellular telephone utilizing a radiation shield, comprising:
- providing the radiation shield comprising:
- a substrate polymer layer;
- and
- a conductive layer, having aperture providing access to a front face of the cellular telephone, adjacent the substrate polymer layer and an opening adjacent at least one of a set of controls;
- removably attaching the radiation shield to the cellular telephone with the opening adjacent at least one of the set of controls and the aperture overlapping a touch-sensitive screen of the cellular telephone;
- and
- operating the cellular telephone;
- whereby the radiation shield attenuates electromagnetic radiation.
