Plain English Summary
Researchers exposed rats to 2.45 GHz microwave radiation (similar to WiFi frequencies) and monitored brain activity and blood flow. Even low-power exposures altered brain wave patterns and increased blood circulation to the brain, showing the brain responds to microwave radiation below heating levels.
Why This Matters
This study provides compelling evidence that microwave radiation affects brain function at power levels well below current safety limits. The researchers found measurable changes in brain electrical activity and blood flow at exposures as low as 10 mW/cm² - levels comparable to what you might experience from a WiFi router or cell phone. What makes this particularly significant is that these effects occurred without tissue heating, challenging the industry's long-held position that only thermal effects matter. The fact that modulated signals produced different brain wave changes than continuous wave signals also suggests our regulatory approach, which ignores modulation patterns, may be inadequate. While this is animal research, the brain's electrical and vascular responses are fundamental biological processes that translate across species.
Exposure Details
- Power Density
- 10, 30 µW/m²
- Source/Device
- 2.45 GHz
- Exposure Duration
- 10 Minutes
Exposure Context
This study used 10, 30 µW/m² for radio frequency:
- 1,000Mx above the Building Biology guideline of 0.1 μW/m²
- 16.7Mx 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.
