There is hardly any place on earth without electric smog. The terminology covers different forms of radiation of fields and waves, which is why we need to differentiate. In the case of alternating current, which in the public power supply for instance changes direction 50 times a second, the frequency, i.e. the number of direction changes per second, is measured in Hertz (Hz). Up to 30,000 Hz (30 kHz) is considered as low frequency, over and  above is considered high frequency.

When electric and magnetic fields are coupled, these are known as electro-magnetic fields. If energy breaks away from the conductor, radiation is produced, for instance in the case of radio, TV and mobile phone waves. Electric and magnetic fields have an effect on the human body: Up to 30 kHz, they stimulate nerve and muscle cells. Furthermore they heat the areas they enter. The best example is a microwave, where a thermal reaction takes place.

As to whether or not this is harmful, depends on the radiation tolerance of each individual person and the specific radiation situation in the house. Should you suspect an increased or harmful exposure, we recommend that you consult an expert.
