Abstract

We investigated the effects of millimeter-wave (MMW) electromagnetic fields on neurite outgrowth in PC12VG cells in vitro. We examined the average length of neurites of 160 cells exposed or sham-exposed to 60 GHz MMWs with circular and linear polarizations at average power density of 1 mW/cm² for two-times of 24 hour exposure. Four parameters, namely the power density, inhomogeneity of the induced distribution, polarization characteristics, and induced temperature increase due to MMW absorption, were determined and analyzed to characterize exposure conditions extensively. Our results suggested that MMW exposure under these exposure conditions has no significant effect on neurite outgrowth in PC12VG cells.
