The effects of exposure to radio frequency (RF) magnetic radiation of the type used in nuclear magnetic resonance imaging and nuclear magnetic resonance spectroscopy on mammalian cells were reviewed. RF radiation has been shown to alter active and passive transport across cell membranes, as well as alter membrane calcium ion binding. Cell energy metabolism and proliferation has also been shown to be sensitive to the effects of RF radiation. A detailed review of the literature on the effects of exposure to RF on the proliferation of human lymphocytes and human glioma cell lines was presented. The relevance of these studies to exposures that result from diagnostic nuclear magnetic resonance imaging and nuclear magnetic resonance spectroscopy procedures was discussed. The authors conclude that there is evidence of direct nonthermal cellular effects of RF radiation exposure using the same general frequency, intensity, and exposure duration ranges employed in diagnostic nuclear magnetic resonance imaging and nuclear magnetic resonance spectroscopy procedures.
