William Walden Mumford · 1969
This 1969 study examined how heat stress affects the body's ability to handle radiofrequency radiation. Researchers found that the standard safety limit of 10 mW/cm² should be reduced by 1 mW/cm² for every point above 70 on the temperature-humidity index. The findings suggest that hot, humid conditions make RF radiation more dangerous to human health.

Herman P. Schwan, Lawrence D. Sher · 1969
This 1969 laboratory study by researcher H.P. Schwan examined how alternating electromagnetic fields cause microscopic particles to move and align in specific patterns. The research found that at field strengths around 100 volts per centimeter, particles form 'pearl chains' and orient themselves along field lines, suggesting biological effects can occur without heating tissue.
B. I. KHODOROV, E. M. PEGANOV · 1969
Researchers tested how different metal ions (calcium, magnesium, barium, nickel, and lanthanum) affect nerve cell electrical responses in frog nerve fibers. They found that these positively charged particles are essential for normal nerve function, with some metals like lanthanum being much more effective than others at stabilizing nerve membranes. This foundational work helps explain how external electromagnetic fields might disrupt the delicate electrical processes in our nervous system.
M. A. K. Hamid, R. J. Boulanger · 1969
Researchers in 1969 developed a microwave-based method to kill three common grain insects (flour beetles, granary weevils, and rusty grain beetles) while simultaneously drying wheat. The study found that microwave energy could selectively heat and kill these pests, with no effect on milling quality or protein content, but breadmaking quality was affected deleteriously and progressively more as the treatment temperature increased. This dual-purpose approach proved cost-effective compared to chemical pesticides and gas treatments used at the time.
Ulrich H. Behling · 1969
This 1969 government report by Ulrich Behling reviewed the biological effects of both radio frequency and low frequency electromagnetic radiation.

This work helped establish the foundation for understanding electromagnetic field interactions with biological tissue.
Raymond Pautrizel et al. · 1969
This 1969 French study investigated whether electromagnetic fields and magnetic fields could boost immune defenses in mice and rats infected with trypanosoma parasites. The research explored using physical stimulation methods to enhance the animals' natural ability to fight off these parasitic infections. This represents early scientific interest in how electromagnetic exposures might influence immune system function.
Dr. David V. Reynolds · 1969
This 1969 research examined the use of electrical stimulation as anesthesia, exploring how electromagnetic fields could reduce pain during medical procedures. The study investigated electroanesthesia as an alternative to chemical anesthetics, using extremely low frequency (ELF) electrical currents applied to the human body. This early work helped establish the foundation for understanding how electromagnetic fields can directly affect nervous system function and pain perception.
J. Li, Peter W. Neurath · 1969
This 1969 study calculated electric and magnetic field distributions around circular coils operating at 27 MHz, a frequency used in commercial applications. The researchers developed mathematical solutions to predict field strengths near these devices, finding that standard textbooks lacked explicit formulas for the electric field patterns. They confirmed their calculations matched actual measurements of magnetic fields from real coils.
S. J. Webb, A. D. Booth · 1969
This 1969 study measured how microorganisms and their genetic material absorb microwave radiation at different frequencies. Researchers found that DNA absorbed significantly more microwave energy than RNA, and that this absorption directly affected biological processes in cells. The findings demonstrated that cellular components have varying sensitivities to microwave frequencies.
K. Takahashi, R. C. Vasishth, W. A. Côté · 1969
This 1969 study examined how microwave drying affects polymer distribution in paper manufacturing compared to conventional oven drying. Researchers found that microwave-dried papers maintained uniform polymer distribution throughout, while conventionally dried papers showed polymer migration to the surface. The study used specialized techniques to analyze cross-sections of treated papers.
Devaux, P · 1969
This 1969 French research examined the physiological dangers of very powerful radar stations on human health, focusing on nervous system, digestive, and visual disorders from electromagnetic emissions. The study represents early scientific recognition that high-power radar systems could cause biological effects in humans. This work helped establish the foundation for understanding occupational EMF exposure risks decades before consumer wireless devices became widespread.
J. C. Lawrence · 1969
This 1969 study exposed animal skin to pulsed 9.6 GHz microwave radiation and found that 6,000 mJ/cm² reduced the skin's cellular breathing (respiratory activity) by 50%. Researchers also examined how this pulsed microwave energy affected the biosynthesis of intercellular materials and specific cell components.
Zorach R. Glaser, Christopher H. Dodge · 1969
This 1969 review compared Soviet and Western research on radio frequency and microwave radiation effects. Soviet scientists consistently reported nervous system changes and behavioral effects, while Western researchers had largely failed to replicate these findings until the late 1960s. The authors noted growing Western evidence supporting some Soviet findings.

Barnothy · 1969
Researchers exposed mice to strong magnetic fields (3,000-10,000 oersted) and found significant organ changes that resembled stress responses. The study suggests magnetic fields may act as environmental stressors, triggering an initial alarm reaction followed by biological adaptation. This early research helped establish that magnetic field exposure can produce measurable physiological effects in living organisms.

This 1968 Soviet research examined how weak electromagnetic stimuli, including constant magnetic fields and microwaves, affect neuroglia (brain support cells) and their protective barrier function. The study found that these EMF exposures can activate neuroglia cells and lead to inhibited states in the central nervous system. The research demonstrated that neuroglia work as an integrated system with neurons and play active roles in nerve cell functioning.
J. T. Cummins, B. E. Vaughan, R. L. Persotti · 1968
Researchers exposed rat stomach tissue to electrical currents at frequencies from 10 to 1,000 Hz and found that both alternating and square wave currents caused the stomach lining to depolarize (lose its electrical charge). While acid production remained normal, the electrical properties of the stomach tissue changed significantly, suggesting direct effects on cellular membranes.

This 1968 study examined how electroanesthesia (electrical current used for anesthesia) affected timing behavior in squirrel monkeys. Researchers investigated whether electrical stimulation altered the animals' ability to perform time-based tasks. The monkeys showed no apparent retardation or breakdown in learning this timing behavior under the forms of anesthesia applied.
