Plain English Summary
Researchers compared the cognitive performance of 100 military radar operators to 57 unexposed controls, testing their reaction times and short-term memory abilities. They found radar workers had significantly faster reaction times but substantially worse memory performance across all measures tested. This suggests that occupational exposure to high-powered radar microwaves (2-18 GHz) may alter brain function in ways that could both help and harm job performance.
Why This Matters
This study reveals a troubling pattern: radar exposure appears to create a neurological trade-off where faster reflexes come at the cost of memory function. The radar operators showed 18% faster reaction times but performed 17-40% worse on various memory tests compared to controls. What makes this particularly concerning is that military radar systems operate at power levels far exceeding consumer devices, yet the cognitive effects were measurable in workers with regular occupational exposure. The science demonstrates that microwave radiation can alter brain function in complex ways. While faster reaction times might seem beneficial in military contexts, the significant memory impairments raise serious questions about long-term cognitive health and job safety for these personnel.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 2–18 GHz
Study Details
The aim of this study was to assess if occupational exposure of military radar personnel affect their general health.
Health effects of occupational exposure to military radar were investigated. Visual reaction time wa...

To the best of our knowledge, this is the first study to show that occupational exposure to radar microwave radiation leads to decreased reaction time and the lower performance of short-term memory. Altogether, these results indicate that occupational exposure to radar microwave radiations may be linked to some non-detrimental and detrimental health effects.
