No Effects Found
Jin H et al · 2015
Power line frequency magnetic fields at extremely high intensities caused no genetic damage in human lung cells.
Plain English Summary
Summary written for general audiences
Korean researchers exposed human lung cells to 60 Hz magnetic fields (the same frequency as power lines) at 1-2 mT strength, both alone and combined with radiation or hydrogen peroxide. They found that magnetic fields alone caused no genetic damage, and didn't make cells more vulnerable to damage from other stressors.

}Quick Questions About This Study
No, this study found that 60 Hz magnetic fields at 1-2 mT strength caused no genetic damage, chromosomal abnormalities, or cell cycle disruption in human lung epithelial cells, even after 9 hours of exposure.
No, 60 Hz magnetic fields did not increase cellular damage when combined with ionizing radiation or hydrogen peroxide. The magnetic fields showed no synergistic effect with these known cellular stressors.
The study used 1-2 mT (millitesla) magnetic fields, which are 1,000-2,000 times stronger than typical household exposures from power lines and electrical appliances that range from 0.1-10 microtesla.
Researchers measured G2/M cell cycle arrest, aneuploidy (abnormal chromosome numbers), and subG1 phase populations (indicating cell death). None of these genetic instability markers increased with magnetic field exposure.
No, the magnetic fields caused no cell death. Researchers found no cells in the subG1 phase, which would indicate apoptotic cell death, even at the high field strengths tested.
