Radio-frequency energy: a hazard to workers?
No Effects Found
Col. L. T. Odland, USAF, MC, and associates · 1973
1973 Air Force study found no vision damage in 700 radar workers, but predates modern EMF research.
Plain English Summary
Summary written for general audiences
This 1973 U.S. Air Force study examined vision health in nearly 700 workers, comparing those exposed to radio-frequency radiation from radar and microwave equipment to unexposed workers. The researchers found no significant differences in visual health between the two groups, suggesting RF exposure didn't damage workers' eyesight.

}Quick Questions About This Study
No, the Air Force study found no significant differences in visual health between workers exposed to radio-frequency radiation from radar equipment and unexposed workers. Both groups had similar eye health outcomes.
The study examined close to 700 workers total, with approximately half working in occupations involving radio-frequency generating equipment like radar units and microwave systems, and half serving as unexposed controls.
The researchers specifically investigated vision because the eyes are particularly vulnerable to electromagnetic radiation damage due to limited blood circulation for cooling and the sensitivity of ocular tissues to heating effects.
The workers operated radio-frequency generating equipment including radar units and microwave systems, which were common military and aviation technologies that produced much higher power RF emissions than consumer devices.
While informative, this study examined much higher power, shorter duration exposures than modern wireless devices. Today's concerns focus on chronic, low-level exposures and non-thermal effects not measured in 1973.
