Abstract: Cellular telephone with a device to protect against radiation generated during its use. It is divided into two groups: a radiation receiver-emitter group (6), consisting of the receiver, the emitter, the antenna (2) and a telescopically extendable support handle for the user, and a personal communication group (7), consisting of the speaker (3); the microphone (4); the keypad (12); the screen (17); and the said casing (5), both of the groups being connected one another via cable or wirelessly. During communication, the radiation receiver-emitter group (6) is distanced from the personal communication group (7), so that the power density of the radiation energy that reaches the personal communication group, and therefore the user, van be less than 0.1 microW/cm2. In the absence of communication, the emitter group can be inserted in a snug manner in a housing provided for that purpose in the casing. It can be used either in individual or collective usages.
