This RF Safe article argues that biological effects from radiofrequency and pulsed electromagnetic fields can be interpreted through two complementary layers: Maxwell–Wagner interfacial polarization (as a direct electrodynamic mechanism at cell membranes) and an “S4–Mito-Spin” framework (as an upstream susceptibility model tied to voltage-sensor density, mitochondrial coupling, and antioxidant buffering). It suggests these mechanisms could converge on outcomes such as altered red-blood-cell stability, blood rheology, membrane deformation, and—at higher intensities—electroporation or hemolysis. The piece is presented as a mechanistic synthesis rather than reporting new experimental results, and it frames potential vulnerability to pulsed/non-native exposures as context-dependent.

A multicenter case-control study in Iran reported that self-reported prolonged mobile phone use was associated with higher odds of confirmed and suspected breast cancer status. The authors emphasize that the findings do not imply causation and note limitations including self-reported exposure and potential residual confounding. They call for larger prospective studies with objective exposure assessment.

This PubMed-listed in vitro study tested whether 1800 MHz RF-EMF exposure can modify chemically induced DNA damage in mouse embryonic fibroblasts under standardized, non-thermal conditions. The authors report RF-EMF alone did not produce detectable DNA damage and did not significantly increase damage from hydrogen peroxide, 4-nitroquinoline-1-oxide, or cadmium. However, co-exposure with hexavalent chromium (Cr(VI)) was reported to synergistically increase DNA damage in the comet assay, which the authors interpret as possible selective exacerbation of Cr(VI)-induced genotoxicity requiring further investigation.

RF Safe criticizes Media Bias/Fact Check (MBFC) for rating it “medium credibility,” arguing MBFC relied on an FDA webpage that was later changed/redirected and on a Harvard T.H. Chan School commentary. The post claims the FDA removed categorical reassurance language about cell phone safety and frames this as undermining MBFC’s critique. It also asserts that non-thermal mechanisms and animal findings support RF Safe’s precautionary stance, while characterizing MBFC’s sources as “opinion” rather than data.

A rat study in Bioelectromagnetics examined GSM-modulated 3.5 GHz RF-EMF exposure (2 h/day for 30 days) and reported adverse changes in male reproductive hormones, oxidative stress markers, and testicular histology. The authors also tested Coenzyme Q10 (CoQ10) and found it partially ameliorated some RF-associated alterations. The paper notes that because the exposure used a GSM-modulated waveform, findings cannot be extrapolated to FR1 5G NR signals, and calls for further research under real-world conditions.

This RF Safe commentary argues that dismissing the National Toxicology Program (NTP) cellphone-radiation animal findings as “too high dose” is misleading because the NTP used multiple exposure tiers, including a lowest tier described as near regulatory relevance. It also claims FDA has removed webpages containing prior “safety conclusion” language while HHS has announced a new study on electromagnetic radiation and health effects, framing these as a meaningful shift in federal public-facing posture. The piece further points to the Ramazzini Institute animal study as suggesting similar tumor signals at lower exposure levels, while acknowledging animal studies alone do not establish human causation.

RF Safe argues that “no effect” (null) findings in RF research should be treated as informative constraints rather than dismissed, within its S4–Mito–Spin mechanistic framework. The post claims biological and exposure heterogeneity can produce nonlinear, tissue- and signal-dependent outcomes, making null results an expected pattern under many study conditions. It references a WHO-commissioned systematic review on RF-EMF and oxidative stress biomarkers as concluding the evidence is of “very low certainty,” citing bias, heterogeneity, and exposure/measurement limitations.

RF Safe publishes a commentary disputing Media Bias Fact Check’s (MBFC) labeling of RF Safe as “pseudoscience” with “mixed factual reporting” and “low credibility.” The post argues MBFC mischaracterized RF Safe’s content as overstating evidence about cell phones and health, claiming RF Safe generally uses cautious, study-referencing language (e.g., “associations,” “potential risks”) and avoids asserting direct human causation. It also points to RF Safe disclaimers that the site is educational and not medical advice, and highlights its research library linking to primary studies such as NTP and Ramazzini animal findings.

RF Safe publishes a rebuttal to Media Bias Fact Check (MBFC) after MBFC labeled RF Safe as “pseudoscience” with “mixed factual reporting” and “low credibility.” The article argues MBFC made factual errors about RF Safe’s research links and ownership/funding, and says MBFC has not corrected the entry despite requests. RF Safe also defends its framing of non-thermal RF/EMF effects as precautionary and grounded in peer-reviewed literature, while criticizing what it characterizes as superficial fact-checking.

This RF Safe commentary argues that U.S. RF exposure protections remain anchored to “thermal-only” assumptions from the 1990s despite what it describes as newer WHO-commissioned systematic reviews elevating certain animal cancer endpoints and a male fertility endpoint to “high certainty.” It contrasts these claims with a WHO-commissioned review of human observational studies that reportedly found mobile-phone RF exposure is likely not associated with increased risk of several head/brain tumors, arguing that this is often overgeneralized in public messaging. The piece calls for “prudent avoidance,” updates to FCC rules, and highlights legal and policy constraints such as federal preemption under the Telecommunications Act and a 2021 D.C. Circuit decision criticizing the FCC’s rationale for retaining its RF limits without adequate explanation.

RF Safe argues that recent WHO-linked evidence reviews have moved beyond a “thermal-only” safety narrative and that policy should respond with stronger protections. The post cites a 2025 WHO-commissioned systematic review in Environment International as concluding with “high certainty” that RF-EMF increases malignant heart schwannomas and brain gliomas in male rats, and references a 2025 corrigendum upgrading certainty for reduced pregnancy rates after male RF exposure in animal experiments. It also points to U.S. FCC rules being rooted in 1996-era assumptions and references a U.S. appellate court remand requiring the FCC to better address non-cancer harms and impacts on children and long-term exposure. The article advocates for the “Clean Ether Act” and promotes RF Safe’s proposed “S4–Mito–Spin” mechanism framework as a non-thermal explanatory model.

This exposure assessment measured outdoor micro-environment RF-EMF levels in daily-life settings across urban and suburban locations in Japan using a portable device (50 MHz–6 GHz) with GPS. Reported exposure levels were higher in urban areas, with railway stations showing the highest levels among the environments measured. The authors emphasize the need for further comprehensive studies and frame prolonged RF-EMF exposure as an ongoing public health concern.

This in vitro study examined strictly non-thermal, GSM-like 3.5 GHz RF-EMF exposure in cultured mouse dorsal root ganglion neurons for 1–24 hours. The authors report time-dependent reductions in cell viability alongside increased ROS and changes consistent with mitochondria-mediated apoptosis (e.g., Bax/caspase-3 up, cytochrome c release, Bcl-2 down) and increased p75NTR. They conclude these findings provide mechanistic evidence of peripheral neuronal vulnerability to mid-band RF exposure and call for further in vivo research.

This in vitro study tested whether 1800 MHz RF-EMF modifies chemically induced DNA damage in mouse embryonic fibroblasts under non-thermal exposure conditions. RF-EMF alone did not produce detectable DNA damage and did not significantly enhance damage from hydrogen peroxide, 4NQO, or cadmium. In contrast, co-exposure with hexavalent chromium (Cr(VI)) was reported to synergistically increase DNA damage, suggesting a selective co-genotoxic interaction under specific chemical conditions.

RF Safe argues that non-native electromagnetic fields (EMFs) can affect biology through timing and redox mechanisms even without tissue heating, framing this as a challenge to common safety narratives focused on thermal effects. The post links circadian disruption (citing a 2025 Frontiers in Psychiatry paper on ADHD and circadian phase delay) to broader vulnerability of biological timing systems, and proposes an “S4–Mito–Spin” framework involving ion-channel timing noise, mitochondrial oxidative stress amplification, and radical-pair/spin chemistry. It also cites a 2018 PLOS Biology study as mechanistic support for cryptochrome-dependent ROS changes under weak pulsed EMF exposure, while presenting these points as converging evidence rather than definitive proof of harm in real-world exposures.

RF Safe argues that companies marketing wireless connectivity to children should adopt a precautionary, “ethical connectivity” approach rather than relying on existing U.S. RF exposure rules. The piece claims current FCC guidelines are outdated and cites a 2021 D.C. Circuit decision criticizing the FCC’s retention of its RF limits, along with assertions about WHO-commissioned reviews and animal evidence. Overall, it frames wireless exposure for children as a credible risk and emphasizes regulatory lag and legal constraints as reasons for voluntary industry action.
