RF Safe argues that non-thermal RF and ELF electromagnetic fields have a coherent biological mechanism and that the regulatory focus on heating-only limits is "no longer tenable." The post proposes a unifying "S4–Mito–Spin" framework linking voltage-gated ion channel voltage sensors (S4), mitochondrial/NOX oxidative stress amplification, and spin-dependent radical-pair chemistry as pathways for diverse reported effects. It cites multiple lines of literature (e.g., oxidative-stress reviews, NTP/Ramazzini animal studies, WHO-commissioned systematic reviews, and a clinical RF therapy device) to support the plausibility of non-thermal effects, while acknowledging mixed and inconsistent findings across studies.
