LOW FREQUENCY ELECTROMAGNETIC FIELDS
Electrosmog is a term commonly used to describe any
phenomenon or problem associated with artificially generated
electric or magnetic fields. A range of electric or electronic
devices may cause an environmental risk and - under certain
conditions - generate potentially hazardous electric or magnetic
fields. However, special attention is focused on low frequency
fields such as those generated by power transmission lines,
railroads, and high current equipment in general (large electric
motors, industrial-scale manufacturing plant, power generators,
etc.). These low frequency fields are basically characterised by
high electric and magnetic field component values in the near
field region, although these values decrease rapidly over
distance. The risk of exposure to potentially harmful low
frequency fields may be present elsewhere (e.g. offices near
large machinery, homes close to a high voltage power line, etc.).
As several studies around the world have confirmed the potential
risks from irradiation with strong low frequency electric or
magnetic fields, electrosmog and its possible consequences are
under close consideration by IEC, CENELEC, ICNIRP and many
other national organisations. New standards are being prepared
and all reasonable protection measures are being taken to
preserve the health of workers and citizens all over the world.
