Effets biologiques et sanitaires des fréquences intermédiaires

Abstract : Intermediate electromagnetic frequencies are those between 300 Hz and 10 MHz. Their use involves induced currents, a mechanism due to extremely low frequencies, and dielectric absorption, due to radiofrequencies. Both mechanisms occur together between 100 kHz and 10 MHz, but the cut-off points at which each predominates are not well defined. Effects depend upon two interwoven phenomena: the organism's macroscopic absorption of the external field and the stimulation of biological effects. These two phenomena differ according to the kind of field (electric or magnetic) and the frequency concerned. We present main sources of these fields in the environment and then explain the phenomena and indicate the field levels at which they are produced. Induced biological effects stimulate nerves at low frequencies and cause heating at the highest frequencies.
