William H. Walter et al. · 1973
Researchers in 1973 tested various cardiac pacemakers against electromagnetic radiation found in urban environments. Many devices malfunctioned when exposed to EMF levels similar to those measured in a major metropolitan area, either switching to fixed-rate mode or shutting down completely. This early study revealed that life-saving medical devices were vulnerable to everyday electromagnetic interference.

Researchers exposed isolated rat hearts to 960 MHz microwave radiation at power levels of 1.5 to 2.5 mW/cm³. Within two minutes, the hearts developed pronounced bradycardia (slowed heart rate) with both regular decreases and temporary cessations. This built on previous turtle heart studies showing similar cardiac effects from microwave exposure.

George F. D'Cunha et al. · 1973
A patient with a Medtronic 5842 pacemaker experienced repeated fainting episodes when near a television transmitter due to radio frequency interference disrupting the device's function. Switching to a titanium-shielded Medtronic 5942 pacemaker resolved the problem, demonstrating that RF fields from broadcast transmitters can interfere with certain medical devices.
James C. Lin, Arthur W. Guy, Curtis C. Johnson · 1973
This 1973 theoretical study used spherical models to calculate how much radiofrequency energy the human body absorbs when exposed to electromagnetic fields between 1-20 MHz. The researchers found that at these frequencies, power absorption is extremely low - less than 2.5×10⁻³ milliwatts per gram of body tissue per milliwatt of incident radiation. The study suggested that thermal safety levels for HF frequencies could be much higher than the 10 mW/cm² recommended for microwaves.

This 1973 study exposed rats to 2400 MHz microwave radiation at 10 mW/cm² power density for chronic periods. Researchers found initial increases in blood cell counts that later normalized, slight temperature increases, and no significant effects on eye health or altitude tolerance. The study represents early research into microwave biological effects.
