Abstract: A radiation shield for a hand-held cellular telephone is made up of a metal strip placed between the antenna rod of the telephone and the speaker. The strip has a flat body portion and an upper portion that is curved away from the rod. Overall length of the strip is slightly longer than the antenna rod, and its width is 1 to 1 1/2 inches. Radiation fields reaching the head of a user whose ear is placed near the speaker are substantially reduced by the shield.
