Abstract

A cellular radio telephone 10 has a radiation shield 8 which may comprise a cover flap 18 (fig.1), moveable between a closed position covering all or part of the keypad 3 and an open position in which the flap provides a barrier between the user's head and the antenna 2. The speaker 6 of the portable phone may be located on the radiation shield. The shield may otherwise comprise a pull-out screen 28, slidable between an open position in which the screen provides a barrier between the user's head and the antenna, and a closed position in which the screen is retractable into the housing 7 of the radiotelephone. The screen can be automatically manoeuvred into the open or closed positions in response to the pressing of a button. The screen, when in the open position, can extend into the interior of the telephone in order to provide a barrier between the user's head and transmitting components within the housing.
