Development of exposure system of intermediate frequency magnetic fields for in vitro test systems

摘要

Health effects of magnetic fields and electromagnetic fields (EMFs) are still concerning in the society. Therefore, WHO is conducting the International EMF Project to evaluate health risk by exposure to EMFs. They already published two environmental health criteria monographs for static electric/magnetic field. (No. 232, in 2006). and time-varying (<100 'kHz) electric field and magnetic field (No. 238, in 2007). In .the EHC No. 232, they summarized that the biological effects of intermediate frequency (IF; from 300 Hz to 10 MHz) MFs have not been studied enough to estimate its health risk, and recommended further research in frequencies between 300 Hz and 100 kHz. In order to deal with this situation, we have started new research project to estimate biological effects and health risks of IF-MFs. In this study, we developed newly designed IF-MFs exposure system for in vitro test systems and started to evaluate biological effects.
