Due to the wider use of new technologies, particularly in the telecommunication sector, the number of electromagnetic field sources has considerably grown over the last few decades. The problem of human exposure to such sources has therefore become increasingly topical.

Main environmental artificial electromagnetic sources include:

• Low frequency electromagnetic fields, generated by power transportation and distribution systems or overhead power lines. These systems, commonly known as ELF, consist of extra high, high, medium and low tension electrical lines, as well as generation plants and transformer stations and rooms;
• High frequency electromagnetic fields, generated by telecommunication plants. These include radio and television broadcasting systems, mobile telephoning systems (radio-base stations), radio, television, fixed-line and mobile telephone connecting systems (radio links) and radars;

Itel’s EMC laboratory provides an electrical, magnetic and electromagnetic measurement service, in accordance with the regulatory framework relating to human exposure.
