Effects
High frequency electromagnetic fields are absorbed by biological systems and lead, above all, to a warming of the tissue. The physical basis of this thermal effect is well known and beyond dispute.
It is questionable, however, if there are non-thermal biological effects in the region of low intensities of high frequency radiation. Their existence has not been proven up to now but intensive research in this field is going on.
