Researchers have raised important concerns about both the electric and the magnetic components of EMF emissions. However, the greater concern is focused on the magnetic part, because repeated studies have linked magnetic field levels to increased childhood cancer deaths. Most magnetic field exposures come from power lines and electrical wiring. Other common sources are waterbeds, electric blankets, computers, fluorescent lights, TVs, telephones, appliances and automobiles. To detect magnetic fields, you can buy or rent a gaussmeter, or have a professional perform an inspection.
Reductions can be as simple as avoiding high exposure locations.
Electrical wiring can be repaired to installed according to low-EMF methods. Specific sources can be shielded. Low emission computers, telephones and appliances are becoming available. Some individuals handle it better, perhaps having a stronger resistance to life's stresses. Others are more sensitive, and in extreme cases may experience allergies, depression, environmental illness, or chronic fatigue syndrome.
