Elektromagnetische Felder

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.

Proven effects

Radiofrequency electromagnetic fields are absorbed by the body mass of living organisms and may subsequently provoke various effects. The absorption of energy depends mainly on the intensity and the frequency of the electromagnetic fields but also on the properties and structure of the biological tissues. Field forces as well as thermal effects of radiofrequency fields have been identified and are physically defined.

Scientifically discussed effects

Studies on biological effects of high-frequency electromagnetic fields were an essential part of the German Mobile Telecommunication Research Programme (Deutsches Mobil-funk Forschungsprogramm, DMF). Research was conducted into both mechanisms of action mainly based on cell experiments and the effects on animals and man with the emphasis placed on po-tential risks to human health.
