50 Hz magnetic field exposure alters onset of S-phase in normal human fibroblasts.

abstract：:Adair [Bioelectromagnetics 14:1-4, 1993] writes that "the effects of 60 Hz magnetic fields of 5 microT (50 mG) or less on biological structures holding magnetite (Fe3O4) are shown to be much smaller than those from thermal agitation; hence such interactions cannot be expected to be biologically significant." This conc...
