Microarray analysis of human-derived cells exposed to intermediate frequency magnetic fields generated by an induction heating (IH) cooktop

There is public concern regarding the potential health effects of induction heating (IH) cooktops in Japan. From IH cooktops, intermediate frequency (IF) magnetic fields at 20 to 90 kHz leak out. However, there have been very few studies of the biological effects of IF magnetic fields. In this study, we evaluated the effects of magnetic fields at 23 kHz and 100 μT from the perspective of gene expression by microarray analysis using human-derived cells. We demonstrate that exposure to IF magnetic fields for up to 6 h did not cause any significant alterations in gene expression.
