Plain English Summary
Researchers exposed mouse cells to 1800-MHz cell phone radiation at levels similar to what phones emit during calls (2 W/kg SAR). They found that even intermittent exposure for just one hour significantly increased harmful reactive oxygen species and caused more cells to die through a process called apoptosis. This demonstrates that cell phone radiation can trigger cellular stress and damage at exposure levels considered safe by current regulations.
Why This Matters
This study adds to mounting evidence that cell phone radiation causes measurable biological harm at exposure levels well within current safety limits. The 2 W/kg SAR used here is exactly the limit allowed for cell phones in many countries, yet it produced clear oxidative stress and increased cell death. What makes this research particularly significant is the intermittent exposure pattern that mirrors real-world phone use - 5 minutes on, 10 minutes off. The science demonstrates that even brief exposures can trigger cellular damage, with effects peaking at just one hour of intermittent exposure. While this was a laboratory study using mouse cells, it provides crucial mechanistic evidence for how radiofrequency radiation disrupts normal cellular function. The reality is that current safety standards were designed decades ago based on heating effects alone, ignoring the growing body of research showing biological impacts at non-thermal levels.

These results indicate that an 1800-MHz EMR enhances ROS formation and promotes apoptosis in NIH/3T3 cells.
