Brain DNA damage and 70-kDa heat shock protein expression in CD1 mice exposed to extremely low frequency magnetic fields
Authors not listed · 2010
Power line frequency magnetic fields caused DNA damage across all brain regions in mice, though damage was reversible.
Plain English Summary
Researchers exposed mice to 50 Hz magnetic fields (the same frequency as power lines) at 1 milliTesla for up to 7 days and found DNA damage in all brain regions immediately after exposure. The DNA damage was reversible, returning to normal levels within 24 hours after exposure ended.
Why This Matters
This study provides direct evidence that power line frequency magnetic fields can damage brain DNA in living mammals. What makes this particularly concerning is that the 50 Hz frequency used is identical to what comes from electrical power systems worldwide. The 1 milliTesla exposure level, while higher than typical household exposures, is within the range you might encounter near power lines or certain electrical equipment. The fact that DNA damage occurred across all brain regions tested suggests this isn't a localized effect but a systemic response to EMF exposure. While the researchers found the damage was reversible after 24 hours, this raises important questions about what happens with chronic, repeated exposures that many of us experience daily from our electrical infrastructure.
