RF Safe argues that “no effect” findings in some RF exposure studies should be interpreted as meaningful negative controls rather than as evidence that RF has no biological effects. The post presents RF Safe’s “S4–Mito–Spin” framework, claiming certain skin cell types (fibroblasts and keratinocytes) are predicted to…

This in vitro study tested whether 5G-modulated 3.5 GHz RF-EMF exposure affects oxidative stress and DNA repair in human skin cells. Under acute exposure conditions (up to 24–48h) at SARs up to 4 W/kg, the authors report no significant changes in ROS markers, no adaptive response to oxidative challenge, and no…
