Erdman WJ · 1960
This 1960 study measured how pulsed high-frequency electrical currents affected blood circulation in the arms and legs of human subjects. Researchers used diathermy equipment (medical heating devices) to apply these radiofrequency fields while monitoring peripheral blood flow changes. The research examined whether pulsed RF energy could influence circulation patterns in living tissue.

This 1960 French study by H. Boiteau examined the biological effects of radar waves on animal subjects, focusing on tissue heating and thermal damage from electromagnetic exposure. The research investigated how different radar frequencies affect living tissue, particularly through hyperthermia (excessive heating). This early work helped establish our understanding of how high-powered electromagnetic fields can cause biological harm through thermal mechanisms.
Cazzamalli, Ferdinando · 1960
This 1960 research by F. Cazzamalli investigated electromagnetic phenomena emitted by the human brain during intense psychological states including dreams, hallucinations, and claimed telepathic experiences.

Unknown authors · 1960
This 1960 technical report examined radiation hazards through electromagnetic analysis and instrumentation development, likely as part of early efforts to understand and measure electromagnetic field exposures. The document appears to have been connected to the GEEIA (possibly General Electric Electronic Industries Association) educational program during the dawn of the electronic age. While specific findings aren't available, this represents foundational work in EMF hazard assessment during a pivotal period in electronics development.
R. L. Carpenter, D. K. Biddle, C. A. Van Ummersen · 1960
This 1960 study exposed rabbit eyes to 2450 MHz microwave radiation and found that it caused cataracts (lens opacities). The research discovered that pulsed radiation was more damaging than continuous waves of equal average power, suggesting non-thermal biological effects. Importantly, eye damage occurred at power levels that didn't cause discomfort to the animals.

A. A. Pokrovskiy · 1960
This 1960 study by Pokrovskiy developed an accelerated laboratory method for measuring cholinesterase enzyme activity in human blood samples. Cholinesterase is a critical enzyme that breaks down acetylcholine, a neurotransmitter essential for nerve and muscle function. The research focused on improving clinical diagnostic techniques for detecting cholinesterase deficiency, which can indicate exposure to certain toxins or neurological conditions.
A. F. Harvey · 1960
This 1960 technical review by A. F. Harvey examined microwave radiation's industrial applications, its effects on biological tissues and living animals, and the hazards for people who must work in positions of intense microwave fields. The paper takes the form of a factual outline, since accurate measurements have been inadequate and reliable conclusions cannot be drawn.
Schliephake, E · 1960
This 1960 German study examined how short-wave electromagnetic radiation affects endocrine glands, particularly the pituitary gland (hypophysis), in humans. The research focused on using microwave stimulation to test gland function and its relationship to vegetative dystonia, a condition involving autonomic nervous system dysfunction. This represents early medical investigation into how electromagnetic fields interact with the body's hormone-producing systems.
E. HENDLER, J. D. HARDY · 1960
Researchers exposed seven people's foreheads to controlled infrared and microwave heating while measuring skin temperature. They found that temperature sensations correlated with how fast skin temperature changed, not the absolute temperature itself. This suggests our temperature sensors respond to the rate of change rather than static heat levels.
Charles Susskind and Staff · 1960
A. A. TEIXEIRA-PINTO et al. · 1960
This 1960 study investigated how radio frequency electromagnetic fields affect the movement and behavior of single-celled organisms like bacteria. Researchers found that motile bacteria had their normal swimming patterns constrained when exposed to RF fields, suggesting non-thermal biological effects. This was among the first scientific evidence that EMF could influence living organisms through mechanisms beyond just heating tissue.
Cazzamalli, Ferdinando · 1960
This 1960 research by F. Cazzamalli investigated what he termed 'cerebro-psychic radiation' - the idea that human brains might emit or respond to electromagnetic radiation during psychological processes. The study used oscillator equipment to explore potential electromagnetic phenomena associated with mental activity. While the specific methodology and findings aren't detailed, this represents early attempts to understand possible connections between brain function and electromagnetic fields.
S. J. Gill, Y. Downing · 1959
Researchers in 1959 developed specialized equipment to measure the magnetic properties of individual biological cells ranging from 1-20 microns in diameter. This pioneering work aimed to understand how single cells respond to magnetic fields when suspended in liquid, laying groundwork for studying cellular interactions with electromagnetic forces.
Charles Süsskind and Staff · 1959
This 1959 technical report by Charles Susskind and staff examined the thermal response of mice to microwave radiation, with further sections on longevity tests and on experiments with cellular organisms. Mice were exposed to power densities ranging between 0.016 and 0.102 W/cm² for periods from 20 minutes to 6 hours at a time. There were no deaths at 0.016 W/cm², 2 out of 5 deaths at 0.047 W/cm², and 5 out of 8 deaths at 0.063 W/cm².

This 1959 technical survey examined methods for measuring radio frequency radiation fields, focusing on three main applications: fundamental electromagnetic wave studies, antenna design, and antenna performance testing. The research catalogued measurement techniques for various RF phenomena including diffraction, scattering, transmission patterns, and radiation gain. This foundational work established standardized approaches for quantifying RF electromagnetic fields that remain relevant today.

Researchers in 1959 exposed mice to 3-centimeter wavelength microwave radiation to study how electromagnetic energy affects body temperature regulation in mammals. The study found that microwave exposure could be used as a research tool to investigate thermal balance and heat exchange processes in warm-blooded animals. This early research laid groundwork for understanding how microwave radiation interacts with biological systems.
J. J. Windle, T. M. Shaw · 1959
This 1953 study measured how water content in wool fibers affects the absorption of microwave radiation at 3000 and 9300 MHz frequencies. Researchers found that as water content increased up to 19%, the wool absorbed significantly more microwave energy, making further measurements impossible due to excessive power loss.

This 1959 study analyzed the composition of human bodies, measuring the ratios of fat, water, and tissue solids excluding bone mineral in 30 healthy people. Researchers found about 0.784 kg of water per kg of body weight less bone mineral and fat, and used an equation verified with freshly isolated tissues to estimate body composition. The study established baseline measurements for understanding how human tissue density varies based on hydration and fat content.
John H. Heller, H. P. Schwan, D. W. C. Shen · 1959
This 1959 research by Heller, Schwan, and Shen demonstrated that radio frequency (RF) radiation produces biological effects in living organisms that cannot be explained by heating alone. The study marked early recognition that electromagnetic fields can affect biological systems through non-thermal mechanisms, challenging the prevailing view that only heat-based effects mattered.
LT Kermit R. Meade, USCG · 1959
This 1959 study by Meade examined radio frequency radiation hazards from radar systems, focusing on safe operating distances and power density measurements around radar antennas. The research addressed growing concerns about RF exposure risks as radar technology expanded in military and civilian applications during the post-war era.
WALTER JOHNSON, VICTOR H. KINDSVATTER, CHRISTOPHER C. SHAW · 1959
This 1959 Navy report examined two radiation problems aboard the USS Galveston, a guided missile cruiser carrying two AN/SPG-49 radar fire-control transmitters: high-power microwave radiation from the radar beams and x-rays from klystron tubes. Radar beams reached 10 milliwatts per square centimeter at distances from 92 feet for one track beam to a calculated 265 feet with all beams on, and to date there had been no known overexposure of personnel to microwave radiation. X-ray intensities reached as high as 10 roentgens per hour at the klystron housing, and temporary lead shielding was installed.
