Plain English Summary
Researchers exposed nerve cells (PC12 cells) to 50 Hz magnetic fields at extremely high levels - up to 1000 microteslas, which is 10,000 times stronger than typical background exposure. They tested both healthy cells and chemically-stressed cells that were more vulnerable to damage. The study found no toxic effects on the nerve cells' calcium balance, oxidative stress levels, or cell membrane integrity, even at these extraordinarily high exposure levels.
Study Details
The aim of this study is to observe Assessment of the neurotoxic potential of exposure to 50 Hz extremely low frequency electromagnetic fields (ELF-EMF) in naïve and chemically stressed PC12 cells
We therefore investigated effects of acute (30 min) and sub-chronic (48 h) exposure to 50 Hz ELF-EMF...
The latter have higher levels of iron and/or reactive oxygen species (ROS) and display increased vul...
Our combined findings thus indicate that exposure to 50 Hz ELF-EMF up to 1000 μT, i.e. 10,000 times above background exposure, does not induce neurotoxic effects in vitro, neither in naïve nor in chemically stressed PC12 cells. Though our data require confirmation, e.g. in developing neuronal cells in vitro or (developing) animals, it appears that the neurotoxic risk of ELF-EMF exposure is limited.
