A 1971 medical case study documented severe blood cell damage when blood was improperly heated in a microwave blood warmer during surgery on a 13-year-old patient. When the blood container wasn't rotated properly during microwave heating, it caused massive destruction of red blood cells (hemolysis). Properly heated blood showed no damage, demonstrating that microwave exposure itself can destroy blood cells under certain conditions.

Researchers in 1971 developed a mathematical model to calculate how microwave radiation penetrates and heats different layers of the human head, including skull, brain tissue, and other structures. They found that simple flat-surface models drastically underestimate radiation absorption, showing the head's spherical shape concentrates microwave energy in ways that create dangerous hot spots inside the brain.

Australian researchers tested how various electrical devices affected three implanted Telectronics P6 pacemakers in 1971. They found that shortwave diathermy therapy equipment caused pacemakers to speed up when applied directly to patients' knees, but common household appliances and microwave ovens had no effect. The study suggested that public fears about pacemaker interference may be overstated.

This 1971 study examined the evolution of retinal detachment treatments, comparing traditional methods like diathermy with newer techniques including cryotherapy, photocoagulation, and scleral buckling. The research evaluated whether advances in electrosurgical and thermal treatments represented genuine progress or created confusion in medical practice.
Konovalenko VA, Yamshanov VA · 1971
Soviet researchers studied how radio frequencies between 1-30 MHz affect the electrical properties of human blood serum. They found that salt content primarily determines how blood responds to these frequencies, while proteins play a smaller role when salt levels are reduced.
