BIOLOGICAL EFFECTS IN RODENTS EXPOSED TO 10⁸ PULSES OF ELECTROMAGNETIC RADIATION
No Effects Found
W. D. SKIDMORE, S. J. BAUM · 1974
Even extreme electromagnetic pulse exposure 1000x higher than human levels showed minimal health effects in long-term animal studies.
Plain English Summary
Summary written for general audiences
Researchers exposed rodents to 100 million pulses of extremely high-intensity electromagnetic radiation over 38 weeks, using field strengths thousands of times higher than typical human exposure. Despite some minor changes in blood cell production, the study found no significant health effects, chromosomal damage, or increased cancer rates in the exposed animals.

}Quick Questions About This Study
The electromagnetic pulse generators produced peak electric field strengths of 447 kV/m (kilovolts per meter), which exceeds typical human EMF exposure by several orders of magnitude and represents military-grade pulse intensities.
Rodents received 100 million (10⁸) electromagnetic pulses over 38 weeks of continuous exposure, delivered at a rate of five pulses per second with brief interruptions for animal care.
No, leukemia-prone AKR/J mice exposed to electromagnetic pulses did not develop leukemia earlier than control mice, nor did a higher percentage of exposed mice develop the disease compared to unexposed controls.
Chromosome analysis of bone marrow cells showed no detectable increases in chromosomal aberrations in rats exposed to electromagnetic pulses compared to unexposed control animals, indicating no genetic damage.
Exposed rats showed consistently higher reticulocyte counts (young red blood cells) and platelet counts decreased by about 10%, suggesting increased blood cell production activity without affecting total blood cell numbers.
