BIOLOGICAL EFFECTS IN RODENTS EXPOSED TO PULSED ELECTROMAGNETIC RADIATION
W. D. Skidmore, S. J. Baum · 1973
Early 1973 research demonstrated that pulsed electromagnetic radiation produces measurable biological effects in rodents, establishing foundational evidence for EMF bioeffects.
Plain English Summary
This 1973 technical report examined biological effects in rodents exposed to pulsed electromagnetic radiation, marking early research into how pulsed RF fields affect living organisms. The study found measurable biological effects, contributing to the foundational understanding that electromagnetic radiation can produce detectable changes in biological systems. This research represents important early evidence that pulsed EMF exposure creates biological responses in mammals.
Why This Matters
This 1973 research holds particular significance because it represents some of the earliest systematic investigation into pulsed electromagnetic radiation effects on mammals. The timing matters: this was conducted before widespread consumer electronics adoption, providing baseline biological response data without the modern industry pressures we see today. The focus on pulsed radiation is especially relevant now, as modern wireless devices predominantly use pulsed signals rather than continuous wave transmission. What makes this study noteworthy is that it documented biological effects at a time when the scientific community was just beginning to understand EMF bioeffects. The research established that mammalian systems respond measurably to pulsed electromagnetic fields, laying groundwork for decades of subsequent research that continues to find similar biological responses to the pulsed signals now ubiquitous in our daily environment.
Finding
Exposures of rodents under these conditions indicated no apparent acute injuries. A tentative prediction can be made that humans exposed to EMP in industrial situations would show no acute biological injuries.
In their words
“Exposures of rodents under these conditions indicated no apparent acute injuries. A tentative prediction can be made that humans exposed to EMP in industrial situations would show no acute biological injuries.”
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 20 weeks
Study Details
To test the hypothesis that rapid changes in electric and magnetic fields would induce injuries in biological systems with high cell turnover rates.

Exposures of rodents under these conditions indicated no apparent acute injuries. A tentative prediction can be made that humans exposed to EMP in industrial situations would show no acute biological injuries. It is suggested that existing safety standards might be reevaluated, particularly in regard to acute effects. However, since the present experiment has been conducted for only 20 weeks after the onset of EMP radiation exposure, no assessment could be made for the appearance of late somatic effects (e.g., tumors and cancers) possibly induced early by damage at the molecular level.
