THE EFFECT OF 9.31 GHZ PULSED MICROWAVE IRRADIATION ON THE LEVER PRESS BEHAVIOR OF OPERANTLY RESPONDING RHESUS MONKEYS
No Effects Found
Authors not listed
Monkeys showed no behavioral changes when exposed to 9.31 GHz microwaves, but behavior may not reveal subtle biological effects.
Plain English Summary
Summary written for general audiences
Researchers trained rhesus monkeys to position their heads directly in front of a 9.31 GHz microwave beam while performing a lever-pressing task for juice rewards. The study found no measurable effects on the monkeys' behavior during microwave exposure. This research examined whether high-frequency microwaves similar to some radar systems could disrupt trained behavioral responses.

}Quick Questions About This Study
The researchers used 9.31 GHz pulsed microwave radiation, which is higher than cell phone frequencies but similar to some radar systems and satellite communications. This frequency falls within the range being explored for advanced wireless technologies.
The monkeys were trained to face a microwave horn antenna voluntarily, positioning their eyes, face and head directly within the microwave beam. They used a quartz mouthpiece that activated both the microwave generator and juice reward system simultaneously.
No, the study found no measurable effects on the monkeys' lever-pressing behavior during microwave exposure. However, behavioral changes represent only one type of biological effect and may not detect more subtle cellular or neurological impacts.
Rhesus monkeys provide a closer biological model to humans than rodents, particularly for brain and behavioral studies. Their larger heads and similar neural structures make them valuable for understanding how microwave radiation might affect primate nervous systems.
At 9.31 GHz, this frequency is much higher than cell phones (typically 0.7-2.7 GHz) but overlaps with some WiFi bands and radar systems. It's also within the range being developed for future 5G and satellite internet applications.
