Biological and Health Effects of High Frequency Electromagnetic Fields
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.

Biological Effects Due to Energy Absorption and Heating
|
|
|
High frequency electromagnetic fields are absorbed by biological systems and may subsequently provoke various effects. The absorption of energy depends mainly on the intensity and the frequency of electromagnetic fields but also on the properties and structure of the biological tissues. Field forces and thermal effects of high frequency fields have been identified and are physically defined.
