EMF in Personal Devices & Wearables

  • -These are the devices that travel with you everywhere-in your pocket, on your wrist, in your ears, and on your lap.
  • -Personal devices and wearables represent your most intimate EMF exposure because they're designed to stay close to your body throughout the day.
  • -Your smartphone radiates radiofrequency energy just inches from your brain during calls, your laptop emits magnetic fields directly onto your lap, and your wireless earbuds transmit Bluetooth signals inside your ear canals.

INFORMATION PROFILE - RADIOFREQUENCY AND MICROWAVE RADIATION

Science Information Services Department · 1978

Rats exposed to pulsed radiofrequency or microwave frequencies for up to three hours a day over 0.5 to 6.0 months showed chemical and cellular blood changes, reduced cardiac, hepatic, and neural metabolism, hepatic histologic changes, and severe testicular damage. Mice exposed to 9 GHz for a few minutes a day for 59 weeks developed monocytic leukosis and myeloid leukemia three times as often as controls. Human studies included a Russian report that cardiovascular patients chronically exposed to microwave radiation did not improve after changing jobs, a Finnish study correlating a radar site with increased fatal heart attacks, and a study of 140 radio and television operators with at least 10 years exposure showing elevated alpha-globulin and total serum protein.
