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.

Smartphone – Tips for Reducing Radiation Exposure

SmartphoneJust as feature phones smartphones use high frequency electromagnetic fields for transmission of speech and data. Besides connecting via mobile networks smartphones often use Wireless Lan (WLan) as well. However, since long term effects could not be sufficiently examined up to now the Federal Office for Radiation Protection (BfS) recommends to keep exposures to these fields as low as reasonably achievable. Further tips for reducing radiation exposure apply for smartphones having additional features. (full text in German only) more...
