  Electromagnetic Fields
Through the use of certain technologies – e. g. power supply network and mobile communication – electric, magnetic and electromagnetic fields are generated in man´s environment. These fields can be described by their strength (amplitude), their oscillation (wave length) and number of oscillations (frequency). One differentiates high-frequency and low-frequency fields, they are part – as is optical radiation – of non-ionising radiation. In contrast to ionising radiation – e. g. X-rays – the energy of this radiation is not sufficient for charging atoms and molecules electrically – for ionising them. Nevertheless can this type of irradiation have impacts on health. Different concepts serve to protect against immediate hazards and as precaution.

Planning and licensing of high-voltage power lines with nationwide (European) interest
|
|
|
According to recent polls more and more people in Germany favour renewable energy from sun and wind. However, the needed infrastructure such as power lines is not always appreciated. Planning and licensing of these new power lines necessitates consideration of all of the different interests involved. Proceedings such as the Grid Expansion Acceleration Act (Netzausbaubeschleunigungsgesetz - NABEG) are essential to facilitate this process. Public participation is another basic concept (full text in German only).

Specific Absorption Rates (SAR) for mobile phones
|
|
Bei der Nutzung von Mobiltelefonen tritt insbesondere im Kopf beim Telefonieren beziehungsweise im Körper beim Tragen eine Absorption hochfrequenter elektromagnetischer Felder auf, die durch die so genannte spezifische Absorptionsrate (SAR), einem Maß für den auf die Gewebemasse bezogenen Leistungsumsatz (W/kg), quantifiziert wird.

Digital Radio of Security Authorities and Organisations
|
|
Security authorities and organisations as, for example, police forces, fire brigades and rescue services operate a radio network of their own which is strictly separated from other radio networks. BfS concluded an agreement with the Federal Agency for Digital Radio of Security Authorities and Organisations (BDBOS). Read up online about basic principles of the Digital Radio of Security Authorities and Organisations, the co-operation of BfS with BDBOS and examinations on health effects of TETRA.
