SOME CONSIDERATIONS REGARDING THE KNOWN BIOLOGICAL EFFECTS OF ELECTROMAGNETIC PULSES, AND THE SETTING OF STANDARDS
William M. Houk, M.D. · 1972
Electromagnetic pulses create unique biological effects that require different safety standards than continuous EMF exposures.
Plain English Summary
This 1972 technical report examined the biological effects of electromagnetic pulses (EMP) and considerations for setting safety standards. The research reviewed known health impacts from high-intensity electromagnetic fields, including those from lightning and other pulse sources. This early work helped establish the foundation for understanding how sudden, intense electromagnetic exposures affect living systems.
Why This Matters
This 1972 report represents crucial early recognition that electromagnetic pulses pose distinct biological risks requiring specific safety standards. While we often focus on chronic low-level EMF exposures from phones and WiFi, electromagnetic pulses deliver massive energy bursts in microseconds - creating entirely different biological stress patterns than continuous exposures. The science demonstrates that pulse characteristics matter enormously: your body responds differently to a lightning strike's electromagnetic pulse than to your router's steady signal, even when average power levels might seem comparable. What makes this research particularly relevant today is our increasing exposure to pulse-like EMF from sources like radar systems, wireless power transfer, and even some medical devices. The reality is that current safety standards still struggle to adequately address pulsed exposures, often averaging energy over time periods that miss the biological significance of sudden electromagnetic surges.
Finding
Most persons who work with radio transmitters and power oscillators are familiar with the hazard of sustaining deep burns if by accident skin contact is made with energized RF terminals. The interesting thing about RF contact burns is that through a conventional maze, which suppresses the shock sensation. does not occur, though heat is felt (8).

Study Details
To consider the known biological effects of electromagnetic pulses and the setting of standards for human exposure
Experiments with seven albino rats exposed to three pulses of 600 kv/m showed temporary performance ...
There is no evidence that EMP has demonstrated itself to present a hazard to even the occupationally exposed if certain precautions are taken to minimize proximity to generating apparatus. Very high field strengths are tolerable, and biological effects research should be directed toward evaluating systems that have response times commensurate with the pulse-rise time and duration, particularly the central nervous system.
