Plain English Summary
Researchers exposed female rats to 3G mobile phone radiation (2100 MHz) for either 10 or 40 days to study DNA damage in brain tissue. They found increased DNA damage after 10 days of exposure, but surprisingly, this damage decreased after 40 days, suggesting the brain may develop protective mechanisms over time. The study used radiation levels similar to what you'd experience during heavy mobile phone use.
Why This Matters
This research reveals a complex biological response to mobile phone radiation that challenges simple assumptions about EMF exposure. The finding that DNA damage initially increases but then decreases suggests our cells may activate repair mechanisms when exposed to chronic radiofrequency radiation. However, we shouldn't interpret this as proof that long-term exposure is safe. The 0.4 W/kg SAR level used in this study is within the range of typical mobile phone emissions, making these findings directly relevant to daily phone use. What this means for you is that even if your body adapts to chronic EMF exposure, the initial damage still occurs, and we don't yet understand the long-term consequences of this cellular stress response.

Where This Falls on the Concern Scale
Study Details
We aimed to evaluate the effect of 2100 MHz radiofrequency radiation emitted by a generator, simulating a 3G-mobile phone on the brain of rats during 10 and 40 days of exposure
The female rats were randomly divided into four groups. Group I; exposed to 3G modulated 2100 MHz RF...
Our main finding was the increased oxidative DNA damage to brain after 10 days of exposure with the ...
The measured decreased quantities of damage during the 40 days of exposure could be the means of adapted and increased DNA repair mechanisms.
