Studies on the Biological Effect of High Frequency Radio Waves (Radar)
No Effects Found
Richard H. Follis, Jr. · 1946
Early 1946 radar study found no biological harm, establishing foundation for modern EMF health research.
Plain English Summary
Summary written for general audiences
This 1946 military study investigated whether radar equipment used during World War II caused biological harm to personnel, following widespread rumors of sterilization and hair loss. The research found no evidence that radar waves produced dangerous biological effects. This represents one of the earliest systematic investigations into high-frequency electromagnetic radiation health effects.

}Quick Questions About This Study
No, the 1946 military study found no evidence that radar exposure caused sterilization or other reproductive harm among personnel, despite widespread rumors during wartime operations.
The study investigated rumors of alopecia (hair loss) among radar personnel but found no evidence linking radar wave exposure to hair loss or other biological effects.
World War II radar equipment operated at much higher power levels than today's consumer electronics, making this study relevant for understanding high-intensity electromagnetic exposure effects.
Researchers were concerned that unshielded X-rays might be emanating from radar apparatus, prompting investigation into both electromagnetic waves and potential ionizing radiation exposure.
Yes, researchers noted this portion of the electromagnetic spectrum had not been explored biologically before, making it a pioneering investigation into high-frequency radiation health effects.
