EMF's, or Electro Magnetic Fields are all around us, but where you live and what equipment is nearby, can influence how much EMF is or could become, an issue. Can the electric and magnetic fields (EMF) to which people are routinely exposed cause health effects? What are sources of EMFs, and when are EMFs dangerous?
EMF (or ElectroMagnetic Field) is a broad term which includes electric fields generated by charged particles in motion, and radiated fields such as TV, radio, hair dryer, and microwaves. Electric fields are measured in units of volts per meter or V/m. Magnetic fields are measured in milli-Gauss or mG. The field is always strongest near the source and diminishes as you move away from the source. These energies have the ability to influence particles at great distances. For example, the radiation from a radio tower influences the atoms within a distant radio antenna, allowing it to pick up the signal. Despite the many wonderful conveniences of electrical technology, the effects of EMF on biological tissue remains the most controversial aspect of the EMF issue, with virtually all scientists agreeing that more research is necessary to determine safe or dangerous levels.
