  • radiotelephones - e.g. Cell Phones - through which electromagnetic radiation emitted or received by them can influence the body tissue of the user. It has not yet been conclusively proven whether this influence, particularly in the area of the ear and thus the human head, is hazardous to health.

Abstract

Le dispositif prévu pour équiper l'écouteur d'un téléphone portable fonctionnant par rayonnement électromagnétique réduit, voire empêche totalement la pénétration dans le corps humain du rayon électromagnétique sortant ou reçu. Le téléphone peut ainsi être équipé soit chez le fabriquant soit ultérieurement par l'usager. Un tel dispositif peut servir d'écran (1e) à une antenne (2e) logée dans une moulure creuse au dos du combiné (3e).
