Plain English Summary
Russian researchers exposed 24 volunteers to cell phone radiation at 902.4 MHz for 15 minutes while measuring their brain activity using EEG. They found significant changes in brain electrical patterns during and after exposure, with the brain showing increased activation that persisted for 30 minutes after the phone was turned off. This demonstrates that cell phone radiation directly alters how the brain functions, even at relatively low power levels.
Why This Matters
This study provides compelling evidence that cell phone radiation doesn't just pass through our brains harmlessly-it actively changes how our brains work. The researchers used a power density of 0.06 mW/cm2, which is well within the range of typical cell phone emissions during calls. What makes this research particularly significant is that the brain changes persisted for the full 30-minute observation period after exposure ended, suggesting these aren't just temporary heating effects but actual alterations in neural activity. The science demonstrates that our brains are bioelectrical organs, and introducing artificial electromagnetic fields disrupts their normal functioning. You don't have to wait for long-term studies to take basic precautions-the evidence shows your brain responds immediately to cell phone radiation.
Exposure Details
- Power Density
- 0.06 µW/m²
- Source/Device
- 902.4 MHz
- Exposure Duration
- 60 min
Exposure Context
This study used 0.06 µW/m² for radio frequency:
