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.
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.
A Monumental Shift: FDA’s Cellphone Radiation Page Overhaul – From Unsubstantiated Safety Claims to Embracing the 1968 Mandate
RF Safe reports that the U.S. FDA substantially revised its cellphone radiation webpages around January 15, 2026, removing or reducing prior language that broadly reassured the public about safety. The article argues the new framing more closely reflects the FDA’s statutory responsibilities under the Radiation Control for Health and Safety Act of 1968 (Public Law 90-602), emphasizing research, monitoring, and public information rather than definitive safety conclusions. It also links the change to a reported HHS announcement of a new study and portrays the update as a shift toward greater transparency, while noting some safety language may remain on the page.
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.
Why RF Safe’s TruthCase Refuses the “99% Blocking” Game — and Why That’s the Point
RF Safe argues that “anti-radiation” phone case marketing based on universal “99% blocking” claims is misleading because real-world phone emissions vary with signal conditions, orientation, and how a case affects the antenna. The post positions RF Safe’s TruthCase/QuantaCase as more credible specifically because it refuses to advertise a single percentage reduction and instead emphasizes design constraints intended to avoid prompting a phone to increase transmit power. It cites a KPIX 5 (CBS San Francisco) test as an example of how flip cases can reduce exposure in some configurations but potentially increase it in others when used differently than intended.
RF Safe’s Market Position and Industry Skepticism
RF Safe argues that while it has operated since 1998 and emphasizes “physics-based” design and education, the broader anti-radiation phone case market is widely criticized for hype and potentially misleading “blocking” claims. The post says some experts consider the category ineffective or even counterproductive, including concerns that poorly designed cases may interfere with antennas and prompt phones to increase transmit power. It positions RF Safe’s QuantaCase/TruthCase as an outlier for transparency and design choices, while noting that independent 2026 testing is limited and some claims rely on demonstrations, older tests, and design critiques.
The International Collaborative Animal Study of Mobile Phone Radiofrequency Radiation Carcinogenicity and Genotoxicity: The Japanese Study
This PubMed-listed animal study reports results from the Japanese arm of an international Japan–Korea collaboration evaluating whether long-term mobile-phone-like RF-EMF exposure causes cancer or genetic damage in rats. Male Sprague Dawley rats were exposed to 900 MHz CDMA-modulated RF-EMF at a whole-body SAR of 4 W/kg for nearly 18.5 hours/day over two years, alongside OECD/GLP genotoxicity and carcinogenicity testing. The authors report no statistically significant increases in neoplastic or non-neoplastic lesions in major organs and no evidence of DNA or chromosomal damage, concluding the findings do not support reproducible carcinogenic or genotoxic effects under these conditions.
Rebutting MBFC’s “Medium Credibility” Rationale for RF Safe (MBFC Updated Jan 8, 2026)
RF Safe publishes a rebuttal to Media Bias Fact Check’s (MBFC) decision to rate the site “Medium Credibility,” addressing MBFC’s concerns about selective citation, one-sided interpretation, alarmist framing, and potential conflicts of interest tied to selling RF-safety products. The post argues RF Safe includes null/negative findings, avoids claiming RF “causes” specific diseases, and maintains editorial/transparency policies meant to separate evidence types and disclose commercial relationships. It also contends MBFC’s critique is partly a dispute over tone and wording (e.g., “primarily” funded by product sales) rather than demonstrated sourcing errors.
Correction Request – MBFC RF Safe Entry (Funding, Conflict Framing, and Null-Evidence Handling)
RF Safe publishes a correction request addressed to Media Bias Fact Check (MBFC) regarding MBFC’s credibility entry about RF Safe. The post argues that MBFC should revise or substantiate claims about RF Safe being “funded primarily” by product sales, adjust conflict-of-interest wording, and reconsider an assertion that RF Safe gives limited weight to null (no-effect) evidence. RF Safe proposes alternative language and links to its own transparency policy, product education pages, and a framework it says explicitly anticipates null results.
Best Anti‑Radiation Phone Case 2026: Why QuantaCase (RF Safe) Is the Stand‑Out Choice
RF Safe argues that many “anti-radiation” phone cases use misleading marketing (e.g., fabric-swatch tests, vague “FCC tested” claims) and that some designs may cause phones to increase transmit power if they interfere with antennas. The article provides a checklist of red flags (magnets/metal plates, detachable shields, unclear orientation instructions) and emphasizes behavioral steps to reduce RF exposure. It promotes RF Safe’s QuantaCase as a “directional shielding” design intended to reduce exposure on the body-facing side while avoiding signal blockage that could prompt higher power output.
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.
The International Collaborative Animal Study of Mobile Phone Radiofrequency Radiation Carcinogenicity and Genotoxicity: The Japanese Study
This international collaborative animal study (Japanese arm) evaluated carcinogenicity and genotoxicity in male Sprague Dawley rats exposed long-term to 900 MHz CDMA-modulated RF-EMFs at 4 W/kg whole-body SAR. The abstract reports no statistically significant increases in neoplastic or non-neoplastic lesions in major organs and no evidence of genotoxicity on comet or micronucleus testing. The authors conclude the findings provide strong evidence of no reproducible carcinogenic or genotoxic effects under the studied conditions.
Measurement of Electromagnetic Fields Exposure to Humans from Electric Vehicles and Their Supply Equipment
This study reports measurements of electric field intensity (E) and magnetic flux density (B) from electric vehicles (inside driver/passenger seats during driving) and EV supply equipment (near chargers during charging) up to 400 kHz in and around Chennai. E and B inside EVs and E around EVSEs were reported to be within ICNIRP/IEEE guideline limits. However, B around certain EVSE positions reportedly exceeded a general public threshold (~200 T), and a preliminary FEM analysis suggested relatively higher fields at charging infrastructure. The authors call for further research on long-term health impacts and recommend policy actions to mitigate exposure.
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.
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.
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.
Why Percentage Claims in Anti-Radiation Phone Cases Are Deceptive: The Truth Behind RF Shielding
RF Safe argues that common marketing claims for anti-radiation phone cases (e.g., “99% shielding”) are misleading because they often rely on controlled lab fabric tests that do not reflect real-world phone use. The post claims factors like shield orientation, phone transmit-power increases under obstruction, frequency differences (including 5G bands), and user/body interactions can reduce or even reverse purported exposure reductions. It also criticizes current regulatory testing frameworks for not requiring phones to be tested with cases and promotes RF Safe’s own “TruthCase/QuantaCase” approach as a more honest alternative.
Grok’s Pick: The Best Anti-Radiation Phone Case in a Sea of Scams and Half-Measures
An RF Safe blog post written in a first-person “Grok” voice argues that many anti-radiation phone cases are ineffective or can increase exposure by causing phones to boost transmit power. It recommends the QuantaCase™ as the best option in late 2025, claiming it “delivers on physics” and avoids common design pitfalls seen in competing products. The post references WHO’s position that low-level exposure is not proven harmful in humans while also citing animal research (e.g., NTP) and proposed mechanisms (e.g., oxidative stress) to justify precautionary use.
From Bell’s Photophone to the Light Age: How Wireless Took a Wrong Turn — and How We Correct It
This RF Safe commentary argues that wireless communications “took a wrong turn” by prioritizing radiofrequency/microwave transmission over light-based approaches, citing Alexander Graham Bell’s 1880 photophone as an alternative model. It suggests that widespread, continuous RF exposure in modern environments is undesirable and proposes light-based, room-scale wireless as more biologically compatible. The piece also speculates about a historical association between Heinrich Hertz’s close-range RF experiments and his later fatal illness, while acknowledging there is no controlled evidence proving causation.
The Clean Ether Light Age Roadmap
RF Safe argues for a transition from microwave-based wireless (cellular/Wi‑Fi/Bluetooth) to light-based communications (e.g., Li‑Fi) to reduce indoor RF exposure. The piece claims chronic, low-level RF exposure may pose health risks beyond heating and calls for a precautionary approach, while also criticizing U.S. legal and regulatory frameworks it says limit local control and rely on older, heat-focused assumptions.
Clean Ether, TruthCase™ & the Light‑First Endgame
RF Safe argues that non-thermal RF and ELF exposures are a credible long-term biological stressor and that current RF safety regulation is outdated and overly focused on thermal effects. The post presents a mechanistic narrative (ion channels, mitochondria/ROS, and spin-dependent chemistry) and links this to calls for behavior change, product use (TruthCase/QuantaCase), and a transition toward Li‑Fi or “light-first” indoor connectivity. It frames regulators as having dismissed evidence and suggests a legal/regulatory failure since the 1990s, while promoting a precautionary “clean ether” approach.
How Weak Magnetic Fields Could Nudge Red Blood Cells into Clumping
This RF Safe article discusses rouleaux formation (reversible red blood cell stacking) and proposes a speculative mechanism by which weak magnetic fields might influence red blood cell surface charge (zeta potential) via spin chemistry in heme-related radical-pair processes. The piece frames the idea as a mechanistic “what if?” rather than a direct claim that everyday phone use causes blood clotting, and it leans on general concepts from hematology and radical-pair magnetosensitivity (e.g., cryptochrome in animals). No new experimental data are presented in the provided text; the argument is largely theoretical and interpretive.
