Biological effects of intermediate frequency magnetic fields — Development of exposure system and evaluate genotoxicity in vitro

To evaluate biological effects of intermediate frequency magnetic fields (IF-MFs), we developed an exposure system for in vitro study. This system is able to generate up to 3.9mT, 21kHz IF-MF under controlled culture condition. Toxicity and effect on frequency of micronucleus in CHL/IU cells by exposure to IF-MFs were investigated. As the results, we have not observed any significant effects by exposure to 21 kHz, up to 3.9 mT IF-MF in both experiment. This suggests that IF-MF is unlikely to cause adverse biological effects.
