View Original AbstractStrong 60-Hz magnetic fields (2,000x household levels) directly damaged DNA and amplified radiation-induced genetic damage in human cells.
Plain English Summary
Researchers exposed human lung cells to 60-Hz magnetic fields at different strengths and measured DNA damage markers. They found that stronger magnetic fields (2 mT) caused DNA damage on their own and made cells more vulnerable to radiation damage, while weaker fields (1 mT) had no effect. This suggests that power-frequency magnetic fields can damage DNA at high enough levels.
Study Details
Genotoxic effects have been considered the gold standard to determine if an environmental factor is a carcinogen, but the currently available data for extremely low frequency time-varying magnetic fields (ELF-MF) remain controversial. As an environmental stimulus, the effect of ELF-MF on cellular DNA may be subtle. Therefore, a more sensitive method and systematic research strategy are warranted to evaluate genotoxicity.
We investigated the effect of ELF-MF in combination with ionizing radiation (IR) or H2O2 on the DNA ...
Exposure to a 60-Hz, 2 mT ELF-MF for 6 h produced increased γ-H2AX expression, as well as γ-H2AX foc...
ELF-MF could affect the DNA damage response and, in combination with different stimuli, provide different effects on γ-H2AX.
