How can you best protect yourself and your loved ones from unwanted electromagnetic fields? As people spend over half of their time at home, this is where you may absorb more electromagnetic radiation than anywhere else. So for best EMF protection, make your home a low-EMF zone. Most of the EMF that people experience at home does NOT come from external sources (power lines, electrical sub-stations, cell phone towers and suchlike) but from electrical equipment and radio transmitting devices INSIDE their home.
