View Original AbstractBacteria showed no genetic mutations when exposed to MRI-strength magnetic fields and radiofrequency radiation for up to one hour.
Plain English Summary
Japanese researchers exposed bacteria commonly used in genetic testing to extremely strong magnetic fields (6.3 Tesla) combined with radiofrequency radiation similar to what's found in MRI machines for up to one hour. They found no increase in genetic mutations compared to unexposed bacteria, suggesting that MRI-level electromagnetic exposures don't cause DNA damage in this bacterial model.
Study Details
The purpose of this study was to examine the safety of magnetic resonance imaging (MRI) by observing whether bacterial mutation occurs in an approximate MRI environment.
We employed a GX-270 FT-NMR unit (JEOL, Ltd.) with a magnetic field strength of 6.3 Tesla. The Salmo...
The rates of revertant mutation in mixed strains and the TA98 strain were not statistically signific...
Therefore, it was concluded that bacterial mutation is not increased by RF radiation under a 6.3 Tesla magnetic field.
