Prucha RV · 1976
Researchers used thermographic imaging to measure how much microwave oven leakage at 915 MHz heats up life-sized human models (phantoms) representing a child and woman. They calculated temperature rises and compared them to other heat sources like sunlight and metabolic activity. The study concluded that current microwave oven safety standards are very conservative.
Ward WD, Gloria A · 1975
This 1975 protocol outlined a research plan to overcome major flaws in previous occupational noise exposure studies. The researchers identified three critical problems: getting accurate hearing tests without interference, finding workplaces with truly steady noise levels, and obtaining reliable exposure histories. The goal was to establish more reliable data for setting workplace noise standards.
Lin JC, Wu CL, Lam CK · 1975
Researchers studied how electromagnetic pulses penetrate into spherical models representing human and animal heads. They found that the electromagnetic energy transmitted into the head is proportional to how rapidly the incident pulse changes over time. This early research helped establish fundamental principles for understanding how pulsed electromagnetic fields interact with biological tissues.
Lancranian I, Maicanescu M, Rafaila E, Klepsch I, Popescu HI · 1975
Researchers studied 31 men (average age 33) who worked around microwaves for an average of 8 years. They found that 70% experienced reduced sex drive and sexual problems, while 74% showed sperm abnormalities including poor sperm movement, low sperm count, and abnormal sperm shape. Hormone levels remained normal, suggesting the microwaves directly affected sperm production rather than hormone systems.

This 1975 research examined microwave ovens as consumer electronics, focusing on electromagnetic radiation exposure and safety standards. The study investigated leakage radiation from these appliances and evaluated existing safety protocols. This early work helped establish understanding of microwave oven emissions during the technology's initial consumer adoption.
D. L. Conover et al. · 1975
This 1975 NIOSH study tested radiofrequency monitoring equipment and conducted preliminary workplace surveys of RF sources. The research found that at least 80% of industrial RF sources exceeded the safety field strength limits (200 V/m electric, 0.5 A/m magnetic) established in the 1974 ANSI standard. The study highlighted critical gaps in RF exposure monitoring techniques and the need for proper near-field measurement protocols.
Clinton C. Brown · 1975
This 1975 research examined electroanesthesia and electrosleep, medical techniques that use electrical stimulation to induce anesthesia or sleep states in humans. The study investigated different electrical waveforms and their effects on consciousness and pain perception. This represents early medical research into how controlled electrical fields can alter brain function and neural activity.

This 1975 study by Dr. W.R. Adey demonstrated that electromagnetic fields can affect the mammalian nervous system without any significant heating of brain tissue. The research showed measurable biological responses occurred with temperature changes of less than 0.1°C, challenging the prevailing belief that only thermal effects from EMF exposure matter for human health.

Earl Cook · 1975
This 1975 analysis examined how high-energy industrial society affects public health, finding that while energy-intensive development improved medicine and nutrition, it also created new health challenges. The study highlighted that indirect health consequences from energy dependence may be harder to address than direct pollution effects.
Larsen JP, Eriksen T · 1975
This 1975 medical case study documented burn injuries that occurred when diathermy equipment (which uses radiofrequency energy for medical heating) was used simultaneously with electrocardiogram (ECG) monitoring. The research examined how combining these two medical devices created dangerous electrical interactions that resulted in patient burns.

This 1975 study compared computer calculations with actual measurements of how radiofrequency energy (10-50 MHz) is absorbed by human and monkey bodies. Researchers found that prolate spheroid mathematical models accurately predicted RF absorption in test phantoms, but ellipsoid models better represented the actual shape of living bodies.
