Terms that are frequently used in the knowledge pages are explained in the glossary. Many biological and medicinal terms are listed. This does not automatically mean that EMFs were a health problem. The connections between EMF, biology and health are shown in the topic pages.

In addition, we also recommend the glossary of the EMF-portal of the Uniklinik RWTH Aachen.

Electro-sensibility (EHS, IEI-EMF)

Electro-sensibility (electromagnetic hyper-sensibility - EHS; idiopathic environmental intolerance attributed to electromagnetic fields - IEI-EMF) refers to the development of discomfort and clinical symptoms which the affected parties attribute to EMFs.


Electro-sensitivity is the ability of a person to perceive/feel electrical fields from power lines (or weak electric currents) even at low field strength.

Electrocardiogram (ECG)

An investigation whereby the electrical activity of the heart is measured and portrayed.

Electroenzephalogram (EEG)

Graphical representation of the brain's electrical activity.

Electromagnetic Fields (EMF)

Electric, magnetic and electromagnetic fields in the frequency spectrum between 0 Hz and 300 GHz. 0 Hz = DC fields; in the AC part of the spectrum, we differentiate between (extremely) low frequency, intermediate frequency and radio frequency fields.

epidemiological studies

Studies that investigate the occurrence of illnesses.


Refers to when an organism is exposed to defined conditions/substances.
