RF Safe describes “S4-Mito-Spin” as a proposed framework for explaining non-thermal biological effects from RF/EMF exposures (phones, Wi‑Fi, cell towers). The article argues the model links three mechanisms—voltage-gated ion channel disruption, mitochondrial oxidative stress, and spin-dependent chemistry—to reported findings such as oxidative damage, circulation changes, and tumors in certain tissues. It cites animal studies (e.g., NTP and Ramazzini) and various 2025 claims (e.g., WHO review, sperm studies, embryo methylation, and ultrasound observations) to support a precautionary interpretation, while acknowledging ongoing debate and non-linear dose-response arguments.
