Biological effects of high-frequency electromagnetic waves
Marha K. · 1963
Scientists documented biological effects from high-frequency electromagnetic waves in 1963, decades before widespread consumer wireless devices.
Plain English Summary
This 1963 technical report by K. Marha examined the biological effects of high-frequency electromagnetic waves on both humans and animals. The research focused on workplace exposures and engineering controls for radiofrequency radiation, representing early scientific recognition that RF waves could impact living systems. This work helped establish foundational understanding of electromagnetic field health effects decades before cell phones became widespread.
Why This Matters
This 1963 report represents a crucial piece of EMF health history that the wireless industry would prefer you forget. While they claim concerns about RF radiation are recent hysteria, scientists like Marha were documenting biological effects from high-frequency electromagnetic waves over 60 years ago. The research examined both human and animal responses to RF exposure, with particular attention to workplace safety and engineering controls. What makes this especially significant is the timing - this was published when RF exposure was primarily occupational, from radar and industrial heating equipment, not the ubiquitous consumer devices we carry today. The science demonstrates that biological effects from RF radiation have been recognized for decades, long before the wireless revolution put these same frequencies in every pocket and on every desk.

Study Details
To discuss the influence of high-frequency electromagnetic waves on living matter, especially in the field of microwaves, dealing with penetration of high-frequency energy into the organism, electromagnetic induction of the body, and the existence of the non-thermal effect of electromagnetic waves
The study found that high-frequency energy absorption in tissue causes an increase in temperature, w...
The biological effects of high-frequency electromagnetic waves are complex and include both thermal and non-thermal effects. The thermal effects are responsible for damage at greater intensities, while non-thermal effects can occur even at lower intensities. The effects are dependent on frequency, intensity, and duration of exposure. The study concludes that high-frequency fields should be considered as biologically active parts of the environment that can have unfavorable effects on the organism. Protection measures including shielding, personal protective equipment, and monitoring are necessary.
