What are electric and magnetic fields (EMFs)?
Electric and magnetic fields are invisible lines of force that surround any electrical device. Power lines, electrical wiring and electrical equipment, as well as many other things, produce EMF. Electric fields are produced by voltage. Magnetic fields result from the flow of current through the wires. EMFs associated with electricity have extremely low frequency, 60 hertz in North America. Volumes of information about EMF research is available through the National Institute of Health’s EMF RAPID web site at http://www.niehs.nih.gov/emfrapid/home.htm How has EMF safety been studied? EMF exposure has been the subject of studies for more than 30 years. Worldwide a variety of studies have been conducted to determine the potential health effects of EMF exposure. Studies include laboratory and clinical studies and epidemiology, which is to study a group of people that has experienced exposure and see if their risk of disease is different than people who have not.
