Main outcome of study (acc. to author)

No differences were found in the mice exposed to magnetic fields for two hours or five days compared with controls. However, in the exposed group for 14 days, a significantly extended cell DNA migration was revealed.
These data together with results from previous studies (see "related articles") indicate that magnetic fields may have genotoxic effects in brain cells.
