Absence of Electromagnetic Pulse Effects on Monkeys and Dogs
No Effects Found
F. G. Hirsch, M.D. and A. Bruner, Ph.D. · 1972
1972 study found no biological effects from electromagnetic pulses in monkeys and dogs using Van de Graaff generator.
Plain English Summary
Summary written for general audiences
This 1972 study by Hirsch tested whether electromagnetic pulses (EMPs) from a Van de Graaff generator caused biological effects in monkeys and dogs. The research found no observable effects from the EMP exposures. This early work helped establish baseline data on high-intensity, short-duration electromagnetic field exposure in mammals.

}Quick Questions About This Study
The study tested both monkeys and dogs for biological responses to electromagnetic pulse exposure. These mammalian species were chosen to provide relevant data about potential effects in higher-order animals with physiology more similar to humans.
Researchers used a Van de Graaff generator to create the electromagnetic pulses. This device produces high-voltage static electricity and can generate intense electromagnetic fields, making it suitable for studying acute exposure effects.
EMPs are extremely high-intensity, short-duration electromagnetic bursts, while wireless devices produce continuous, lower-intensity radiofrequency radiation. The exposure patterns, frequencies, and biological interaction mechanisms are fundamentally different between these two types of electromagnetic fields.
This early research established baseline data on electromagnetic field effects in mammals and demonstrated scientific methods for studying EMF bioeffects. It helped lay groundwork for the extensive EMF research that followed in subsequent decades.
The study reported an absence of biological effects from the electromagnetic pulse exposures in both monkeys and dogs. No observable physiological changes or adverse health impacts were detected in the test animals.
