About Cordless Phones (DECT) EMF

  • -That cordless phone sitting in your kitchen or living room may seem like a harmless relic from the pre-smartphone era, but it's actually one of the most potent sources of radiofrequency (RF) radiation in your home.
  • -DECT phones (Digital Enhanced Cordless Telecommunications) operate at 1.9 GHz, continuously transmitting RF signals between the handset and base station even when you're not making calls.
  • -Think of it like having a mini cell tower running 24/7 in your house, except this one sits just inches from your head during conversations and often much closer to your body throughout the day.
