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.

THE EFFECTS OF MICRO-WAVES A PRELIMINARY INVESTIGATION

A. C. BOYLE, H. R. COOK, T. J. BUCHANAN · 1950

This 1950 British investigation by A.C. Boyle represents one of the earliest scientific examinations of microwave radiation's biological effects on humans. Published just five years after World War II, when radar technology introduced widespread microwave exposure, this preliminary research helped establish the foundation for understanding how these electromagnetic fields interact with human biology.

Temperature dependence of the dielectric constant of blood at low frequencies

H. Schwan · 1948

This 1948 research by Schwan examined how temperature affects the dielectric properties of human blood when exposed to low-frequency electromagnetic fields. The study investigated how blood's electrical characteristics change with temperature variations, providing foundational data for understanding how EMF interacts with biological tissues. This early work helped establish the scientific basis for measuring electromagnetic effects in living systems.

Heating of human tissues by micro wave radiation

Horvath SM, Miller RN, Hutt BK · 1948

This 1948 study by Horvath examined how microwave radiation heats human tissues, investigating temperature gradients and thermal effects in the body. The research explored microwave diathermy applications and measured tissue temperature changes during exposure. This represents some of the earliest scientific investigation into how microwave energy interacts with human biology.

The effect of the presence of metals in tissues subjected to diathermy treatment

Lion KS · 1947

This 1947 research investigated how metals present in biological tissues affect heating patterns during diathermy treatment, which uses radiofrequency electromagnetic fields for therapeutic heating. The study examined whether metal implants or naturally occurring metals in tissues could concentrate electromagnetic fields and create dangerous hot spots. This early work helped establish safety protocols for electromagnetic medical treatments.

SHORT WAVE DIATHERMY – PRELIMINARY REPORT

FRANK HAMMOND KRUSEN, M.D. · 1939

Ultra-short waves showed no selective temperature or electromagnetic effects on staphylococci and streptococci in vitro across various media and exposure times up to eight and a half hours. Clinical measurements during pelvic treatment found no pronounced heat effect in the bladder, vagina, or rectum despite noticeable skin heating and patient sensations of heat. Fire hazards were documented when electrode insulation burst into flame and when cables contacted each other, burning a patient and a technician.
