This paper reports a multiphysics electromagnetic–thermal simulation of radiofrequency (RF) antenna exposure for a subway station attendant, estimating specific absorption rate (SAR) and temperature rise in the trunk and selected organs at 900, 2600, and 3500 MHz. Using a COMSOL-based model with a detailed human anatomy representation, the authors found simulated SAR and temperature increases that they state are well below ICNIRP occupational exposure limits. The study concludes that RF emissions from antennas in the modeled subway environment pose low health risk for female attendants with similar characteristics to the model used, while noting the work is based on simulations rather than measurements.
Low-Cost Sensors in 5G RF-EMF Exposure Monitoring: Validity and Challenges
This PubMed-listed review examines how 5G deployment (denser small cells and beamforming) changes RF-EMF exposure patterns and evaluates the validity of low-cost sensors for 5G exposure monitoring. Reviewing over 60 studies across Sub-6 GHz and emerging mmWave systems, it reports that well-calibrated low-cost sensors can approach professional instruments within a few dB, but highlights persistent challenges such as calibration drift, frequency coverage gaps, and data interoperability. The authors argue that standardized calibration protocols and open data frameworks could help low-cost sensors complement professional monitoring and improve transparency.
RFK Jr. Was Right to Pull FDA’s Blanket “Cell Phone Radiation Is Safe” Assurances
This RF Safe commentary argues that HHS, under Secretary Robert F. Kennedy Jr., was correct to remove FDA webpages that gave broad assurances that cell phone radiation is “not dangerous.” It claims blanket safety messaging is scientifically indefensible given animal toxicology findings (notably the U.S. National Toxicology Program studies), a WHO-commissioned systematic review of animal cancer studies (Mevissen et al., 2025), and references to federal court findings. The piece frames the change as a precautionary, science-based correction rather than an anti-science move.
Cell Phone Radiation: What HHS/FDA actually did—and why that matters
This RF Safe commentary argues that Reuters-reported actions by HHS and FDA—launching an HHS study and removing older FDA webpages stating cellphones are “not dangerous”—should be understood as a risk-communication/scientific-integrity adjustment rather than a declaration of confirmed harm. It contends that categorical safety messaging is not justified given mixed evidence, citing the D.C. Circuit’s 2021 decision criticizing FCC reliance on conclusory FDA statements, along with selected human, animal, and mechanistic literature. The post calls for more uncertainty-aware, evidence-graded public messaging about RF exposure from phones.
Effect of fat thickness on subcutaneous temperature field under monopolar radiofrequency
This PubMed-listed study models and experimentally validates how subcutaneous fat thickness affects temperature distribution during monopolar radiofrequency (RF) treatment used for skin tightening and tissue repair. Using finite element analysis (COMSOL) and in vitro pork tissue experiments, the authors report that thicker fat layers reduce achieved intratissue temperatures under the same RF settings. The paper concludes that RF energy parameters may need adjustment based on adipose thickness to reach desired effects while staying within stated epidermal safety limits.
The Mechanistic Pivot: Why HHS and FDA Must Fund Predictive Biology Now (S4–Mito–Spin)
This RF Safe commentary argues that if HHS and FDA pursue a “reset” on cellphone radiation policy, they should fund mechanistic, predictive biology rather than relying on literature summaries or general safety reassurances. It cites the NTP rat bioassays and a WHO-commissioned animal cancer systematic review (Mevissen et al., 2025) as motivation, emphasizing reported tissue-selective findings and non-monotonic dose patterns. The post proposes a mechanistic framework (“S4–Mito–Spin”) and calls for research to map boundary conditions across tissues and exposure parameters to inform standards beyond SAR/thermal assumptions.
RFK Jr., HHS, and the FDA’s Cell Phone Radiation Reset
This RF Safe article reports that in mid-January 2026 HHS, led by Secretary Robert F. Kennedy Jr., removed or redirected certain FDA webpages that previously conveyed strong “no-risk” conclusions about cellphone radiation. It argues the updated FDA framing emphasizes statutory duties (monitoring, testing, hazard control) and signals a shift from definitive safety messaging toward renewed inquiry, while noting that details of any planned research have not been publicly disclosed. The piece also highlights Kennedy’s past public statements alleging harms from Wi‑Fi/5G and links the policy context to the 2021 D.C. Circuit remand of FCC RF policy.
The Federal Script Just Changed on Cellphone Radiation: FDA Deletes “Old Conclusions” as HHS Launches a New Study
RF Safe reports that HHS confirmed plans to launch a new study on cellphone radiation and that an HHS spokesperson said the FDA removed webpages with “old conclusions” while new research is undertaken to identify knowledge gaps, including for emerging technologies. The article frames the FDA webpage changes as a meaningful shift away from categorical reassurance, while noting Reuters’ reporting that some FDA and CDC pages still state there is no credible evidence of health problems from cellphone radiation. It also links the development to the 2021 D.C. Circuit decision in Environmental Health Trust v. FCC, arguing the ruling exposed weaknesses in the FCC’s reliance on other agencies’ statements.
The Anti‑Radiation Phone Case Market Runs on Percentages. RF Safe Refuses to Sell One.
RF Safe critiques the anti-radiation phone case market for relying on headline percentage-blocking claims that may reflect tests of shielding material rather than real-world phone behavior in a case on a live network. The article argues that poorly designed or misused shielding cases can interfere with a phone’s signal and prompt higher transmit power, potentially increasing exposure in some scenarios. It positions RF Safe’s QuantaCase/TruthCase as avoiding percentage marketing claims and emphasizes a systems-engineering approach to testing and use, while noting that health causation from typical consumer RF exposure remains debated by authorities.
If You’re Reading This, You Are the Resistance
This RF Safe commentary frames readers as part of a “resistance” movement seeking changes to U.S. wireless policy and RF exposure governance. It argues that current FCC RF exposure rules and related laws constrain local decision-making and rely on a “thermal-only” safety framework that the author says is outdated. The post cites a WHO-commissioned 2025 systematic review on RF-EMF and cancer in experimental animals as part of a broader WHO review effort, and advocates shifting indoor connectivity toward light-based technologies.
Why the S4 Mito Spin Framework Stays Out of Human Causation Debates – And Why That’s a Strength for RF/EMF Safety Advocacy
RF Safe argues that its “S4-Mito-Spin” framework should avoid debates about whether cell phones cause human disease and instead focus on mechanistic and animal evidence for non-thermal RF/EMF biological effects. The post claims the framework synthesizes established concepts (ion-channel interactions, mitochondrial/NOX-driven ROS, and radical-pair/quantum spin effects) to explain why some lab studies find effects and others do not. It also cites a WHO-commissioned systematic review and a U.S. court ruling to support calls for updating RF exposure guidelines beyond thermal-only assumptions.
RF Safe Never Downplays Null Results
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.
Ethical Connectivity Is Not Optional: A Public Challenge to Beast Mobile and Trump Mobile
RF Safe argues that celebrity-branded mobile services (citing reported plans for “Beast Mobile” and the announced “Trump Mobile”) could normalize near-body, all-day phone use—especially among children—and therefore carry ethical responsibility for scaled RF exposure. The piece cites legal and scientific developments (including the 2021 Environmental Health Trust v. FCC decision, the U.S. NTP animal studies, and a WHO-commissioned systematic review) to claim the evidence base has “moved decisively” toward concern about long-term RF-EMF effects. It also promotes a proposed mechanistic framework ("S4–Mito–Spin") and suggests shifting indoor connectivity toward Li‑Fi (IEEE 802.11bb) as a harm-reduction approach.
High-Certainty RF Harms vs. 1996 Rules: Why Prudent Avoidance Is Now the Only Responsible Default
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.
Mechanisms, High Certainty Evidence, and Why the Clean Ether Act Is Now a Public Health Imperative
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.
The Systems of Radiological Protection for Ionizing and Non-Ionizing Radiation
This article summarizes expert presentations and a panel discussion on radiological protection systems for ionizing and non-ionizing radiation at an international congress. It highlights that ionizing radiation protection is mature and continually revised, while non-ionizing radiation protection lacks a comparable international framework. The authors emphasize that emerging non-ionizing technologies create complex exposure scenarios and unresolved concerns about chronic and acute exposures, calling for a more cohesive and protective framework.
On exposure-response interpretation and evidence synthesis in low-intensity RF-EMF research
This paper presents a methodological discussion about how to interpret exposure-response patterns and synthesize evidence in low-intensity RF-EMF research, focusing on animal cancer bioassays. It references an exchange around a systematic review on RF-EMF and cancer in experimental animals and critiques/considers approaches to statistical inference and evidence synthesis. The authors emphasize that methodological choices can materially influence carcinogenic hazard identification and argue for rigorous, evidence-based analysis in risk assessment.
When biology meets polarity: Toward a unified framework for sex-dependent responses to magnetic polarity in living systems
This narrative review discusses sex-dependent responses to magnetic field polarity and direction in living systems and proposes a unified framework integrating magnetobiology with sex-based physiology. It describes potential interaction mechanisms (e.g., ion channel modulation, radical pair dynamics, ion cyclotron resonance) and notes that some reported outcomes differ by sex depending on polarity. The author suggests that failing to account for polarity and direction could miss relevant health risks and calls for experimental paradigms that treat sex as a key biological variable.
Parametric analysis of electromagnetic wave interactions with layered biological tissues for varying frequency, polarization, and fat thickness
This PubMed-listed study models how RF electromagnetic waves interact with a simplified three-layer tissue structure (skin–fat–muscle) across common ISM bands (433, 915, 2450, 5800 MHz), varying polarization (TE/TM), incidence angle, and fat thickness. Using a custom MATLAB pipeline combining multilayer transmission-line methods, Cole–Cole dielectric parameters, and a steady-state Pennes bioheat solution, the authors estimate reflection, absorption, and resulting temperature rise. The simulations report small temperature increases at lower frequencies (433–915 MHz) and larger superficial heating at 5.8 GHz under the modeled conditions, highlighting how fat thickness and wave parameters modulate dosimetry and thermal outcomes.
Towards a Planetary Health Impact Assessment Framework: Exploring Expert Knowledge and Artificial Intelligence for a RF-EMF Exposure Case-Study
This peer-reviewed article proposes a Planetary Health Impact Assessment (PHIA) framework to evaluate not only direct health effects of radiofrequency electromagnetic fields (RF-EMF) but also potential indirect impacts on human health mediated through ecosystem disruption. Using mobile telecommunication RF-EMF as a case study, the authors and 12 experts built a knowledge graph of hypothesized pathways and compared it with an AI/NLP tool that extracts literature into knowledge graphs. The paper reports that AI can process large volumes quickly but currently needs substantial expert validation due to limitations in precision and context sensitivity, and it highlights potential gaps in the literature on indirect/ecological pathways.
RF Safe Launches “Ethical Connectivity Pledge,” Calls on Beast Mobile, Trump Mobile, and Celebrity Backed Wireless Plans to Lead the Light Age With Integrity
RF Safe announced an “Ethical Connectivity Pledge” aimed at celebrity- and creator-branded mobile plans, urging them to adopt child-first design standards, improve transparency, and invest in lower-exposure connectivity options such as Li‑Fi where feasible. The organization argues that current microwave-based wireless networks may pose plausible health risks—especially for children—and that business models can externalize long-term health costs onto families and public systems. The pledge is presented as a public signatory framework with tiers of commitment and an intent to enable public scrutiny of follow-through.
The “Good Light → Bad Light” Problem
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.
MrBeast: If You’re Going to Launch “Beast Mobile,” Don’t Put a Microwave Transmitter in Kids’ Pockets Without a LiFi Exit
RF Safe argues that a potential MrBeast-branded mobile service (“Beast Mobile”) could drive high adoption among children and therefore raises ethical concerns about children’s exposure to radiofrequency (RF) emissions from always-on, body-worn devices. The post claims the scientific and legal context has shifted and contends that relying on existing regulatory compliance is insufficient, urging a “LiFi compatibility plan” as an exposure-reduction alternative. It cites modeling literature about potentially higher localized absorption in children and references a 2025 systematic review it says found increased cancer incidence in RF-exposed experimental animals, while framing the overall situation as negligence if child-focused marketing proceeds without additional safeguards.
This piece does not argue that radiofrequency (RF) electromagnetic fields “cause” any single disease.
An RF Safe commentary argues that persistent, pulsed “non-native” RF electromagnetic noise can disrupt biological “timing coherence,” leading to downstream “fidelity losses,” particularly in electrically active tissues. It also emphasizes that smartphones are adaptive RF systems that change transmit power and modulation, so accessories that detune antennas or distort near-field conditions may cause phones to transmit harder. The piece cites FTC warnings that partial-shield products can be ineffective and may increase emissions by interfering with signal quality, and it argues that material shielding claims do not directly translate to real-world exposure outcomes.
How non‑native electromagnetic fields, biological timing, and policy lock in converge — and why the Light Age is the only coherent exit
RF Safe argues that modern radiofrequency (RF) exposures are complex (adaptive, nonlinear, geometry- and near-field–dependent) and that biological effects, if any, may be better understood as “timing/coherence” disruptions rather than direct single-cause disease claims. The piece cautions against simplistic “percent blocking” marketing for anti-radiation accessories, claiming real-world emissions can change when antenna boundary conditions are altered. It proposes an explanatory framework (“S4–Mito–Spin”) and suggests a policy/technology “exit” via indoor photonics (Li‑Fi/optical wireless) rather than continued expansion of microwave-based systems, while explicitly stating it does not claim RF causes specific human diseases or that products protect health.
