Plain English Summary
Researchers exposed rabbit eyes to low-power microwave radiation at levels of 5 and 10 mW/cm² for 3 hours and found significant damage to lens cells. At the lower power level, many cells began dying through a process called apoptosis, while the higher level caused severe cell death and tissue damage. This demonstrates that microwave radiation can harm eye tissue even at relatively low power levels through non-thermal mechanisms.
Why This Matters
This study provides compelling evidence that microwave radiation damages eye tissue at power densities well below levels that cause heating. The power levels tested (5-10 mW/cm²) are within range of what you might encounter from some wireless devices, though typically at much shorter exposure durations than the 3-hour experimental period. What makes this research particularly significant is that it demonstrates non-thermal biological effects - meaning the damage occurred without the tissue getting hot, challenging the industry's long-held position that only heating effects matter. The fact that researchers observed both early cellular death (apoptosis) and more severe tissue damage suggests a dose-response relationship, where higher exposures cause progressively worse effects. While this was an animal study, the biological mechanisms involved are fundamental to mammalian cells, making the findings relevant to human health concerns about wireless device exposure to the eyes.

- 5,10 µW/m²
- Exposure Duration
- 3 Hours
Exposure Context
This study used 5,10 µW/m² for radio frequency:
- 500Mx above the Building Biology guideline of 0.1 μW/m²
- 8.3Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
To determine whether low power density microwave radiation can induce irreversible changes in rabbit lens epithelial cells (LECs) and the mechanisms of the changes.
One eye of each rabbit was exposed to 5 mW/cm2 or 10 mW/cm2 power density microwaves for 3 hours, wh...
Lots of rabbit LECs were in the initial phase of apoptosis in the 5 mW/cm2 microwave radiation group...
Low power densities of microwave radiation (5 mW/cm2 and 10 mW/cm2) can induce irreversible damage to rabbit LECs. This may be the non-thermal effect of microwave radiation.
