Electromagnetic Fields

Usage of a Mobil PhoneElectromagnetic 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.

Power lines and radiation protection (Video)
StromtrasseDue to increased use of renewable energy from solar and wind sources the expansion of electricity networks is essential in meeting the long-term energy challenges. As additional high-voltage lines are generating electric and magnetic fields, radiation protection is a key issue that has to be dealt with.

In a video BfS provides information on radiation protection during the grid expansion (in German only). more...

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. more...
