How strong are ELF fields near power-lines, wiring and appliances?
Electromagnetic fields (EMF) are a combination of invisible electric and magnetic fields of force. They occur both naturally and due to human activity. Naturally occurring EMF are for example, the earth static magnetic field to which we are constantly exposed, electric fields caused by electric charges in the clouds or by the static electricity produced when two objects are rubbed together as well as sudden electric and magnetic fields caused by lightning, etc. Man-made electromagnetic fields (EMF) are for example generated by extremely low frequency (ELF) sources, such as power-lines, wiring and appliances (the focus of this study) as well as by higher frequency sources such as radio and television antennas and, more recently, cellular telephones and their antennas (which are not reviewed in this study).
