Soviet Radiobiology
Authors not listed · 1968
1968 military intelligence recognized electromagnetic fields could alter brain electrical activity in animals.
Plain English Summary
This 1968 U.S. Air Technical Division report examined Soviet research on how electromagnetic and magnetic fields affect brain electrical activity in rabbits. The study used electroencephalography (EEG) to measure brain wave changes during field exposure. This Cold War-era document represents early government interest in understanding electromagnetic effects on biological systems.
Why This Matters
This declassified 1968 report reveals the U.S. military's early recognition that electromagnetic fields could measurably affect brain function - a concern significant enough to warrant intelligence gathering on Soviet research. The focus on brain biopotentials in rabbits suggests researchers were investigating whether EMF exposure could alter normal brain electrical patterns, potentially affecting cognition or behavior.
What makes this particularly relevant today is that we're now surrounded by electromagnetic fields at levels unimaginable in 1968. While this report studied controlled laboratory exposures, modern brains encounter constant EMF from WiFi, cell phones, and wireless devices operating at similar and higher frequencies. The science demonstrates that if electromagnetic fields could measurably change brain activity in rabbits over 50 years ago, our current exponentially higher exposures deserve serious scientific attention.

Exposure Context
This study used 42.5 mW/cm² for radio frequency:
- 4,250Mx above the Building Biology guideline of 0.1 μW/m²
- 70.8Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
This study used 460 gauss for magnetic fields:
- 2.3Kx above the Building Biology guideline of 0.2 mG
- 460x above the BioInitiative Report recommendation of 1 mG
This study used 30 V/m for electric fields:
- 100x above the Building Biology guideline of 0.3 V/m
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
To investigate the biological effects of constant magnetic fields, ultrahigh and superhigh frequency electromagnetic fields, and ionizing radiation on the central nervous system of rabbits, specifically examining EEG responses and the role of different brain formations.
ESD tests were run on the recticular formation of the midbrain, the posterior ventrolateral thalamic...
Exposure to constant magnetic field resulted in increased EEG responses in the vA. The exposure was ...
The predominant action of the constant magnetic field and the electromagnetic fields of the investigated intensities on the central nervous system is not specific. It was not possible to conclude that the mechanism of EEG reactions to the magnetic and electromagnetic fields really differs from responses to ionizing radiation, only that the EEG reactions to the constant magnetic field and the electromagnetic fields of the given intensities do not correspond to previously described electrical reactions of the cerebral cortex to ionizing radiation.
