1. In a cellular telephone:

  • a housing containing a radio transmitter adapted to be held to the head of a person using the telephone, an antenna connected to the transmitter and extending from one end of the housing for emitting electromagnetic radiation, a shield fabricated of a plastic material having carbon fibers embedded therein for absorbing and dispersing the electromagnetic radiation, and a hinge mounting the shield to the housing toward the one end for movement about an axis perpendicular to the antenna between a position adjacent to the housing and a position adjacent to the antenna for protecting the person from the radiation emitted by the antenna, the hinge permitting movement of the shield along the axis so that the shield can be positioned directly between the antenna and the head of the person using the telephone.
