EMF Around Us

Electromagnetic fields (EMF) have always existed on Earth in nature. An example is electric field produced by the local build-up of electric charges in the atmosphere associated with thunderstorms. However the invention of man-made devices during the twentieth century has increased the amount of EMF that surrounds us exponentially. Electricity demand, wireless technologies, telecommunications, and broadcasting have all brought ever increasing amounts of electromagnetic radiation into our environment and medical equipment such as magnetic resonance imaging devices and soft tissue healing appliances are directly impacting our physical bodies. This has caused much scientific and political debate regarding the potential for the adverse health effects of EMF at long-term and high levels of exposure. The technologies that emit EMF are providing us social and economic benefits as they improve the quality of our lives. No one really wants to live without electricity and both broadcasting and telecommunications have become an integral part of modern life.
