Electric and magnetic fields, commonly known as EMF, exist wherever electric current flows, including around any electric appliance or wires that conducts electricity. Whenever you turn on a lamp, use a microwave or use your computer, these frequencies are around.
The health impacts of EMF has been studied for more than 40 years by government and scientific organizations around the world. The balance of scientific evidence indicates exposure to electric and magnetic fields cannot conclusively be linked to the cause of disease. Organizations include the World Health Organization and the United States National Cancer Institute and others.
