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.

SCIENTIFIC LITERATURE EVALUATION GROUP

Roger Budd, Przemyslaw Czerski, LeRoy W. Schroeder

Researchers infected African green monkey kidney cells with herpes simplex virus and exposed them to a pulsed electromagnetic field for varying periods up to 48 hours. After 48 hours, they counted viral plaques and measured plaque size. Two experiments found no statistically significant differences in plaque numbers between exposed and control cultures. An initial suggestion of larger plaques in longer exposures was not confirmed in a second experiment with more uniform cell monolayers. The authors concluded that the screening system did not detect a biological effect of the pulsed electromagnetic field, though the device has been shown to affect immune cell functions in other studies.

A Review of United States Microwave Exposure Criteria

Vernon E. Rose et al.

Early standards treated 10 mw/cm2 as a maximum permissible level that should not be exceeded and considered only power density. Later standards introduced time-weighted exposure concepts allowing levels above 10 mw/cm2 for limited durations. The 1966 USASI standard set a protection guide at 10 mw/cm2 averaged over 0.1 hour and used an energy density of 1 mwh/cm2 for shorter periods.

Human Response to Very-Low Frequency Electromagnetic Energy

Alan H. Frey

This technical report by A.H. Frey examined how humans respond to very-low frequency (VLF) electromagnetic energy, focusing on exposures from broadcasting stations and measuring physiological effects at various field strengths. The research documented measurable human responses to VLF electromagnetic fields, contributing early evidence that extremely low frequency EMF can produce biological effects in people.
