Single strand DNA breaks in rat brain cells exposed to microwave radiation.
Paulraj R, Behari J. · 2006
View Original AbstractChronic microwave exposure at WiFi frequencies caused significant DNA damage in developing rat brains at radiation levels comparable to close device contact.
Plain English Summary
Researchers exposed developing rat brains to microwave radiation at frequencies used in WiFi (2.45 GHz) and other wireless devices (16.5 GHz) for 35 days. They found statistically significant increases in DNA single strand breaks in brain cells compared to unexposed rats. This suggests that chronic microwave exposure during brain development may cause genetic damage that could potentially lead to long-term health problems.
Why This Matters
This study adds to growing evidence that microwave radiation can damage DNA in brain tissue, particularly concerning since it examined developing brains during a critical growth period. The 2.45 GHz frequency tested is identical to what WiFi routers and microwave ovens use, while 16.5 GHz falls within ranges used by newer wireless technologies. The SAR levels (1.0 and 2.01 W/kg) are within ranges you might experience from prolonged close contact with wireless devices. What makes this research particularly significant is that DNA damage in developing brain tissue could have lasting consequences, as the brain undergoes rapid growth and development during youth. The science demonstrates that chronic exposure to these everyday frequencies can break DNA strands in brain cells, raising important questions about cumulative effects from our wireless-saturated environment.
Exposure Details
- SAR
- 1.0 (with 2.45 GHz) and 2.01 (with 16.5 GHz) W/kg
- Source/Device
- 2.45 and 16.5 GHz
- Exposure Duration
- 35 days
Exposure Context
This study used 1.0 (with 2.45 GHz) and 2.01 (with 16.5 GHz) W/kg for SAR (device absorption):
- 2.5x above the Building Biology guideline of 0.4 W/kg

Where This Falls on the Concern Scale
Study Details
To investigate the effect of microwave exposure (2.45 and 16.5 GHz) on developing rat brain (35 days old).
Wistar rats (35 days old, male, six rats in each group) were selected for this study. These animals ...
This study shows that the chronic exposure to these radiations cause statistically significant (p < 0.001) increase in DNA single strand breaks in brain cells of rat.
