P. C. PEDERSEN, C. C. JOHNSON, C. H. DURNEY, D. G. BRAGG · 1976
This 1976 study developed a medical diagnostic technique using microwave radiation to detect lung conditions like pulmonary edema. Researchers found that diseased lung tissue changes how microwaves are reflected and transmitted, allowing doctors to monitor heart and lung problems. The technique measures both amplitude and phase changes in microwave signals.
Charles Burton, MD · 1976
This 1976 research by Burton examined transcutaneous electrical nerve stimulation (TENS) as a pain relief method, exploring how controlled electrical currents applied through the skin can reduce pain perception. The study represents early work in understanding how electrical fields can therapeutically interact with human nerve function. This research helped establish the foundation for modern TENS therapy devices used in pain management.
R. A. MOIDEL, S. K. WOLFSON, JR., R. G. SELKER, S. B. WEINER · 1976
Researchers in 1976 studied implanting metallic materials like carbon steel rods into brain tissue, then exposing the head to radiofrequency electromagnetic fields to create localized heating. They found that carbon steel rods and Hysterloy heated most effectively (about 1000 and 655 cal/g-min, respectively), with rods oriented parallel to the RF field producing the most heat. The goal was to combine targeted brain heating with chemotherapy to concentrate cancer drugs in tumors while keeping healthy tissue cool.

Researchers investigated why electrical stimulation through the skin often causes sharp, pricking pain. They discovered the pain results from thermal damage to the skin's outer layer caused by high energy concentrations at uneven skin-electrode contact points. The study found this pain can be controlled through proper electrode application techniques without using conductive gels.
Arthur W. Guy, Michael D. Webb, Carrol C. Sorensen · 1976
Researchers used scale models and thermographic imaging to measure how much radiofrequency energy the human body absorbs when exposed to high-frequency electromagnetic fields. They found that exposure to 31 MHz radiation at 10 mW/cm² can create power absorption densities as high as 5.63 W/kg in certain body regions. This pioneering 1976 study helped establish methods for measuring EMF absorption that are still used today.
Webb MD, Guy AW, McDougall JA · 1976
Researchers used thermal imaging to study how microwave oven radiation at 915 MHz absorbed into human-sized phantom models made with muscle-equivalent materials.

The study mapped energy absorption patterns in both adult female and child models.
Udintsev NA, Moroz VV · 1976
Soviet researchers in 1976 studied how alternating magnetic fields affect the body's stress response system, specifically the pituitary-adrenal axis. They found that extremely low frequency (ELF) magnetic fields can trigger measurable changes in this critical hormonal pathway that controls our response to stress. This suggests that common EMF sources in our environment may be activating stress responses in our bodies without us realizing it.
