About Cell Phones EMF

  • -Your cell phone is likely the most significant source of EMF exposure in your daily life.
  • -Every time you make a call, send a text, or stream a video, your phone emits radiofrequency (RF) radiation in the 700 MHz to 2.7 GHz range to communicate with cell towers.
  • -This radiation doesn't stop at your phone's case-it penetrates into your body, with the strongest exposure occurring in tissues closest to the device.
