Brain cells show oxidative damage from cell phone radiation in under an hour at levels below current safety limits.

Plain English Summary

Summary written for general audiences

Croatian researchers exposed human brain cells to cell phone radiation for 10-60 minutes and found significant cellular damage. Even brief exposures increased harmful molecules that damage cells, with one hour causing damage to fats and proteins. This shows brain cells are vulnerable to short-term radiation exposure.

Why This Matters

This research adds to mounting evidence that radiofrequency radiation triggers oxidative stress in brain cells, even at exposure levels within current safety guidelines. The 1.6 W/kg SAR used in this study is below the 2.0 W/kg limit for mobile phones in many countries, yet still produced measurable cellular damage within an hour. What makes this study particularly significant is that it used human neuroblastoma cells, which closely mimic brain tissue responses. The finding that oxidative stress occurred at all exposure durations tested suggests that even brief phone calls may initiate cellular damage processes. The science demonstrates that current safety standards, based solely on heating effects, fail to account for these non-thermal biological responses that occur at much lower exposure levels.
