Source of EMF
While using the latest technology and other electrical devices in our everyday situations we inevitably expose ourselves to electromagnetic field. The most common sources of electromagnetic field are household appliances, computers, telecommunication devices, TV sets, mobile phones computers, other devices and electric cables. Exposure to electromagnetic field of low frequency is also found in close proximity to high voltage lines. Also there are high frequency magnetic fields which are a result of the use of radio, TV, wireless devices or mobile phones, induction heaters and anti-theft devices.
