About Power Lines EMF

  • -Every time you flip a light switch or plug in an appliance, you're tapping into an electrical grid that requires power lines to carry electricity from power plants to your home.
  • -These overhead and underground transmission lines create extremely low frequency (ELF) magnetic fields as electricity flows through them - and unlike the electric fields that walls can block, these magnetic fields pass right through buildings, cars, and human tissue.
  • -While power companies have long maintained these fields pose no health risks, our database contains 476 peer-reviewed studies on ELF magnetic field exposure, with 87% finding measurable biological effects.
