A. R. Livenson · 1968
This 1968 study measured how much microwave energy reflects off the human body surface versus getting absorbed into tissues. Researchers found that about 50% of medical microwave energy (460-2375 MHz) bounces off the body, with the exact percentage varying based on individual body characteristics and frequency used.
Françoise M. L. Attinger · 1968
Researchers tested dog arterial walls under different strain conditions to understand how blood vessels behave mechanically. They found that arteries are anisotropic (behave differently in different directions) rather than uniform, with different elastic properties when stretched tangentially versus longitudinally. This challenges common assumptions used in vascular system modeling.
A. M. Kadoum, S. O. Nelson, L. E. Stetson · 1967
Researchers exposed yellow mealworm larvae to radiofrequency radiation and found that RF energy caused deadly internal heating in the insects. The thoracic region (chest area) reached the highest temperatures due to body appendages concentrating electric fields, with internal temperatures approaching lethal levels that likely caused the observed deaths.
Ahmed M. Kadoum, Harold J. Ball, LaVerne E. Stetson · 1967
Researchers exposed mealworm larvae to radiofrequency electric fields and found they lost weight progressively after treatment, with younger larvae losing more weight than older ones. The treated larvae also showed elevated oxygen consumption that persisted for days, similar to patterns seen in surgically injured larvae.
Smurova, Ye. J. · 1967
Soviet researchers exposed 45 white rats to three different radiofrequency electromagnetic fields daily for over two months to study effects on immune system function. The study measured how well the rats' blood cells could engulf and kill bacteria (phagocytic and bacteriocidal activity). Results showed changes in immune function, though specific outcomes aren't detailed in the available abstract.
R. C. Sharma · 1967
This 1967 study by Sharma investigated how cells behave when exposed to alternating electric fields, focusing on the electrical properties of cell membranes and how they respond to changing electromagnetic conditions. The research examined the fundamental mechanisms behind cellular reactions to electric field exposure, laying groundwork for understanding how EMF affects living tissue at the cellular level.
STANISLAW BARANSKI, ZBIGNIEW EDELWEJN · 1967
Polish researchers exposed 70 male rabbits to microwave radiation for 60 days, measuring brain wave activity and examining brain tissue under microscopes. They found that chronic microwave exposure at power levels that didn't heat the tissue still caused measurable changes in brain function and structure. Pulsed microwaves produced more pronounced effects than continuous waves.
Constant PC, Jr · 1967
This 1967 study investigated whether humans can actually hear electromagnetic waves, particularly microwaves, as some people had reported. The research aimed to determine if this auditory sensation was real and whether people could learn to detect EM radiation through hearing.
Kouwenhoven WB et al. · 1967
Johns Hopkins researchers conducted a 30-month medical study of 11 electrical linemen exposed to high-voltage 60-Hz power line fields during maintenance work. The study tracked physiological changes in workers using both conventional hot stick methods and barehanded techniques from aerial buckets connected to energized conductors. This represents one of the earliest comprehensive medical evaluations of occupational EMF exposure effects.
Chai SY, Vogelhut PO · 1967
Researchers used 9.36 GHz microwave radiation to study how water molecules bind to hemoglobin protein. They found that microwaves could detect changes in water structure around the protein, showing a linear relationship up to specific hydration levels. Above certain water concentrations, ice-like structures formed on the hemoglobin surface.
Zadradnik J W, Chen C S · 1967
This 1967 study developed a new laboratory method for predicting how many bacteria survive thermal heating processes. The researchers found that traditional prediction methods were flawed because they assumed simple kill rates and ignored how bacteria's pre-heating conditions affect their heat resistance. Their improved method accounts for these real-world variables.
Mishina IM · 1967
Soviet researchers in 1967 developed a calorimetric method to measure thermal effects from the Luch-58 ultrahigh frequency medical device. This study focused on quantifying heat generation in tissues exposed to microwave therapy equipment. The research represents early efforts to understand and measure the heating effects of medical microwave devices.
Chizhenkova RA · 1967
This 1967 Soviet research examined how rabbit brain tissue responds electrically to various electromagnetic field exposures, measuring changes in brain wave patterns (EEG). The study represents early scientific investigation into how EMF exposure affects neural activity in living animals. While specific findings aren't available, this research contributed to foundational understanding of electromagnetic field interactions with brain tissue.
G. G. Knickerbocker, W. B. Kouwenhoven, H. C. Barnes · 1967
Researchers exposed 22 male mice to intense 60 Hz electric fields (4 kV/inch) for nearly 1,500 hours over 10.5 months to test for health effects. The exposed mice showed no changes in health or reproduction, but their male offspring showed altered growth patterns. This early study examined power frequency fields at levels far exceeding typical household exposure.
A. W. Guy, J. F. Lehmann · 1967
This 1967 conference paper examined how electromagnetic energy heats different human tissues, using thermographic imaging of tissue-equivalent models to measure temperature patterns. The research aimed to optimize medical diathermy treatments, improve implanted device power transfer, and establish safety limits for personnel exposed to powerful electromagnetic fields. This foundational work helped establish early understanding of how microwaves interact with human tissue.
Itsuo Yamaura, Shiko Chichibui · 1967
Researchers exposed crayfish and prawn nerve clusters to 11 gigahertz microwave radiation at 300mW/mm² power density. The microwaves suppressed normal nerve firing patterns, with stronger radiation causing longer suppression periods. This 1967 study provided early evidence that microwave radiation can directly disrupt nervous system function in living organisms.
R. A. CHIZHENKOVA · 1967
Soviet researchers exposed rabbits to magnetic fields and microwave radiation, then measured brain wave changes using EEG technology. They found that both constant magnetic fields (460 oersteds) and microwave frequencies caused distinct brain wave alterations, including increased 'spindles' and slow, high-amplitude waves. Even after surgically removing key brain structures, the electromagnetic effects persisted, suggesting direct brain stimulation rather than reflex responses.
Maroncelli M, Ferraro G · 1967
This 1967 study investigated a new physical therapy approach using electromagnetic fields (diathermy) to treat chronic simple otitis, a persistent ear infection condition. The research examined radiofrequency electromagnetic field therapy as a treatment method for patients with ongoing ear inflammation. This represents early medical research into therapeutic applications of EMF technology.
Samuel A. Goldblith, Daniel I. C. Wang · 1967
Researchers exposed E. coli bacteria and B. subtilis spores to 2,450 MHz microwave radiation and compared their death rates to conventional heating. They found that microwaves killed the microorganisms at exactly the same rate as regular heat at the same temperature. This suggests microwaves work purely through heating effects, not through any special electromagnetic properties.
W. Stodolnik-Baranska · 1967
In 1967, researchers discovered that microwave radiation could transform human lymphocytes (white blood cells) into blast-like cells in laboratory cultures. This transformation normally requires chemical stimulants, but microwaves alone triggered the same cellular changes. The finding suggests microwave radiation can fundamentally alter immune cell behavior.

The research focused on understanding the eye's vulnerability to microwave exposure, which was becoming a growing concern as radar and microwave technologies expanded. This work helped establish early understanding of how electromagnetic radiation can damage delicate eye tissues.
Unknown authors · 1967
Researchers in 1967 developed a technique to measure how vegetation interacts with microwave radiation at frequencies around 8-10 GHz. They found that fresh plants with 65% moisture content had a dielectric constant of approximately 29, which dropped dramatically to about 1.5 as the plants dried out. This demonstrates that water content is the primary factor determining how plants absorb and reflect microwave energy.
