Electric and magnetic fields | Radio waves
A power line channels the energy it carries, so that the fields produced stay “confined” along the wires.
In contrast, telecommunications antennas are designed to emit their energy in the form of radio frequencies. The signals they transmit travel over great distances.
Michel Plante, medical consultant, and Jean-Pierre Tardif, scientific communications advisor at the Hydro-Québec’s research institute, explain the differences between what happens near power lines and near telecommunications equipment.
