Electromagnetic Exposure from RF Antennas on Subway Station Attendant: A Thermal Analysis

Research PubMed: RF-EMF health Jan 28, 2026

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.

The Mechanistic Pivot: Why HHS and FDA Must Fund Predictive Biology Now (S4–Mito–Spin)

Independent Voices RF Safe Jan 18, 2026

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.

Negative Controls That Matter

Independent Voices RF Safe Jan 14, 2026

RF Safe argues that “no effect” findings in some RF exposure studies should be interpreted as meaningful negative controls rather than as evidence that RF has no biological effects. The post presents RF Safe’s “S4–Mito–Spin” framework, claiming certain skin cell types (fibroblasts and keratinocytes) are predicted to be relatively resistant to non-thermal RF effects, so null results in these cells can be consistent with the model. It cites in-vitro studies at 3.5 GHz (5G-modulated) reporting no changes in ROS measures, stress responses, or UV-B DNA repair kinetics under specified SAR conditions, and frames these nulls as boundary conditions rather than a general safety conclusion.

The International Collaborative Animal Study of Mobile Phone Radiofrequency Radiation Carcinogenicity and Genotoxicity: The Japanese Study

Research PubMed: RF-EMF health Jan 13, 2026

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.

RF Safe Is Built on Tools, Not Hype: The SAR Database, the 4,000+ Study Research Viewer, and the TruthCase Standard

Resources RF Safe Jan 10, 2026

RF Safe presents itself as an RF exposure advocacy and education project promoting “RF exposure literacy,” safer-use habits, and updated safety frameworks beyond thermal-only assumptions. The post highlights RF Safe’s tools, including a SAR comparison database based on FCC SAR data, a public research viewer described as containing 4,000+ peer-reviewed studies, and its “TruthCase”/editorial standards. It argues that non-thermal biological interactions are reported in experimental literature and that compliance with current SAR limits does not necessarily reflect optimal real-world exposure outcomes.

The International Collaborative Animal Study of Mobile Phone Radiofrequency Radiation Carcinogenicity and Genotoxicity: The Japanese Study

Research RF Safe Research Library Jan 1, 2026

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.

Effects of wireless local area network exposure on testicular morphology and VEGF levels

Research RF Safe Research Library Jan 1, 2026

This rat study examined 2.45 GHz WLAN-like EMF exposure (3 V/m; SAR 0.00208 W/kg) for 1 hour/day over 60 days and assessed testicular morphology and VEGF-related markers. The abstract reports increased VEGFA gene expression and protein levels in exposed animals, with no change in HIF1A expression. It also reports multiple histological changes interpreted as testicular damage in the exposed group.

RF Safe’s Radical Marketing – Zero Ads, All Education in the EMF Safety World

Independent Voices RF Safe Dec 10, 2025

RF Safe promotes an education-first, zero-paid-ad marketing approach for its EMF safety products, positioning itself against what it describes as a market full of overhyped or misleading “anti-radiation” gadgets. The article highlights RF Safe’s resources (e.g., a large study library and SAR tools) and argues its products (notably the QuantaCase) align with “physics” and avoid deceptive claims. It also repeats the founder’s personal story linking a family tragedy to prenatal EMF exposure and references various external claims (e.g., WHO animal findings, court criticism of FCC limits) without providing primary documentation in the text.

EMF-The Dangers and How to Mitigate Risk

Independent Voices RF Safe Dec 4, 2025

RF Safe recaps a Truth Expedition podcast episode featuring RF Safe founder John Coates discussing alleged biological risks from EMF exposure and arguing that current regulations lag behind modern science. The piece links EMFs to developmental and health concerns (including neural-tube defects and autism) via Coates’ proposed “S4–Mito–Spin” framework involving voltage-gated ion channels, mitochondrial signaling, and radical-pair/spin chemistry. It also promotes RF Safe’s research library, SAR comparison tools, and mitigation products as part of a risk-reduction approach.

The animal carcinogenicity evidence is no longer reasonably dismissible

Independent Voices RF Safe Nov 26, 2025

RF Safe argues that animal evidence for RF-related carcinogenicity is now strong and should not be dismissed, citing the NTP (2018) and Ramazzini (2018) lifetime rodent studies as showing statistically significant increases in the same rare tumor types (heart schwannomas and brain gliomas). The post further claims that effects occurred at relatively low whole-body SAR levels and references additional mechanistic hypotheses (e.g., VGCC-related models and radical-pair/spin effects) and a reported human ultrasound observation of acute non-thermal changes. These points are presented as supporting a shift away from a “thermal-only” interpretation, but the item is advocacy/commentary and does not provide full methodological details in the excerpt.

What the strongest literature actually shows now

Independent Voices RF Safe Nov 25, 2025

This RF Safe article argues that the “strongest” RF-EMF literature supports concern about cancer-related findings, emphasizing non-monotonic dose–response patterns in the U.S. National Toxicology Program (NTP) rat study and citing additional analyses and animal studies. It reports that FDA evaluations have downplayed the human relevance of NTP results due to high exposures and inconsistencies, and counters that some effects may occur at lower exposure levels than commonly claimed. The piece also references the Ramazzini Institute rat study as supportive evidence at lower whole-body SARs and mentions a 2024 PLOS ONE paper analyzing Ramazzini tumors, but provides limited detail in the excerpt.

RF device that is FDA approved because it produces non thermal bioelectric effects

Independent Voices RF Safe Nov 14, 2025

RF Safe argues that an FDA-authorized therapeutic radiofrequency device (TheraBionic P1) demonstrates biologically meaningful “non-thermal” RF effects, and contrasts this with consumer wireless regulation that it says is based primarily on heating (SAR) limits set in 1996. The post frames this as a regulatory and legal gap, citing the Radiation Control for Health and Safety Act and Telecommunications Act Section 704 as factors limiting local and public-health oversight. It also references several epidemiology and animal studies (e.g., Interphone, Hardell, CERENAT, IARC 2011 classification, and the U.S. NTP rodent studies) to support the claim that non-thermal effects and health risks warrant stronger scrutiny, though the article’s presentation is advocacy-oriented.

Radio Frequency Exposure in Military Contexts: A Narrative Review of Thermal Effects and Safety Considerations

Research RF Safe Research Library Jan 1, 2025

This narrative review focuses on RF exposure in military contexts, emphasizing thermal effects as the established mechanism of harm and discussing safety limits set by bodies such as ICNIRP and IEEE. It reports that whole-body SAR limits (≤4 W/kg) generally prevent dangerous core temperature rises, but localized heating risks may persist for tissues like skin and eyes, especially when thermoregulation is impaired. The review highlights CEM43 as a potentially useful thermal-dose metric but notes complexity for transient exposures and calls for improved models and methods across relevant frequency bands.

NTP Lite: The Japan-Korea Collaborative RF Exposure Toxicity Project [Health Matters]

Research RF Safe Research Library Jan 1, 2025

This magazine article reviews the Japan-Korea "NTP Lite" RF animal toxicity collaboration and its relationship to prior NTP (2018) and Ramazzini Institute reports of RF-associated tumors in male rats. It notes NTP Lite used a single whole-body SAR of 4 W/kg and completed a two-year exposure phase in 2022, but final reporting is delayed with histopathology and genotoxicity work ongoing. The author highlights protocol harmonization across labs while raising concerns about unexplained animal deaths and physiological differences in exposed groups, and frames the broader evidence as supportive of RF-related cancer risk in laboratory animals.

Model Variability in Assessment of Human Exposure to Radiofrequency Fields

Research RF Safe Research Library Jan 1, 2025

This review examines how variability in computational dosimetry models affects assessment of human RF exposure from MHz to terahertz frequencies, focusing on SAR, absorbed power density, and temperature rise. It reports that anatomical scaling and model choices can drive meaningful differences in predicted SAR (including higher values in children/smaller models), while temperature-rise predictions are especially sensitive to thermophysiological parameters and vascular modeling. The authors indicate that computed variability remains within ICNIRP/IEEE safety margins but argue that uncertainties warrant ongoing research and refinement as new technologies (e.g., 6G) emerge.

Non-thermal biological effects of radiofrequency electromagnetic radiation: Mechanistic insights into male reproductive vulnerability in the era of ubiquitous exposure

Research RF Safe Research Library Jan 1, 2025

This narrative review discusses proposed non-thermal mechanisms by which chronic, low-intensity RF-EMR from ubiquitous wireless sources may affect male reproductive health. It highlights oxidative stress, mitochondrial dysfunction, impaired testosterone synthesis/steroidogenesis, and declines in sperm quality as reported outcomes. The authors argue that current SAR/thermal-based guidelines may not capture these endpoints and call for updated standards and precautionary measures.

Radiofrequency radiation-induced gene expression

Research RF Safe Research Library Jan 1, 2025

This review summarizes studies reporting radiofrequency radiation (RFR)-associated changes in gene expression across biological systems. Reported affected genes relate to cellular stress responses, oxidative processes, apoptosis, DNA damage detection/repair, protein repair, and neural function regulation. The authors highlight reported gene expression effects at or below 0.4 W/kg SAR and argue this challenges current guideline assumptions, while noting that not all studies find significant effects.

Effects of Simultaneous In-Vitro Exposure to 5G-Modulated 3.5 GHz and GSM-Modulated 1.8 GHz Radio-Frequency Electromagnetic Fields on Neuronal Network Electrical Activity and Cellular Stress in Skin Fibroblast Cells

Research RF Safe Research Library Jan 1, 2025

This in-vitro study exposed primary cortical neurons and human immortalized skin fibroblasts to simultaneous 5G-modulated 3.5 GHz and GSM-modulated 1.8 GHz RF-EMF at SARs of 1 or 4 W/kg. It reports no significant changes in neuronal network firing/bursting activity and no alteration of mitochondrial ROS in fibroblasts. Stress-related signaling readouts showed only minor, threshold-level variations without a consistent pattern, and no HSF1 activation was observed. Overall, the authors conclude there is no strong evidence of biological effects under these exposure conditions.

Thermal and SAR-Based Limits for Human Skin Exposed to Terahertz Radiation

Research RF Safe Research Library Jan 1, 2025

This conference paper uses COMSOL Multiphysics simulations to evaluate thermal and SAR-based exposure limits for modeled human skin exposed to terahertz radiation (0.1–5 THz). The authors report negligible temperature increases at power densities consistent with keeping SAR below 1.6 W/kg, but note that higher power densities can yield minimal heating while producing SAR values above recognized safety thresholds. They conclude that existing sub-THz standards are not directly transferable to the full THz band and call for updated guidelines, especially for prolonged exposure.

Investigation of fetal exposure to electromagnetic waves between 2.45 and 5 GHz during pregnancy

Research RF Safe Research Library Jan 1, 2025

This dosimetry study simulated fetal RF-EMF exposure between 2.45 and 5 GHz during the second trimester, estimating SAR10g in fetal brain and lungs. The presence of a belly-button piercing increased SAR, with maxima reported at 2.45 GHz (16 mW/kg in lungs; 14 mW/kg in brain). Despite these increases, all SAR values were reported to remain below IEEE and ICNIRP limits, while the authors note a precautionary implication regarding metal objects during pregnancy.

Dosimetric Electromagnetic Safety of People With Implants: A Neglected Population?

Research RF Safe Research Library Jan 1, 2025

This dosimetric study evaluated whether existing EM safety guidelines protect individuals with conductive implants by assessing implant-related local field enhancements. Across 10 kHz to 1 GHz, the authors report large increases in psSAR10mg and local electric fields near implants, particularly below 100 MHz. In human anatomical models with implants exposed to an 85 kHz wireless power transfer coil and a 450 MHz dipole, the study reports guideline exceedances and elevated psSAR10mg, while the modeled temperature rise at 450 MHz remained under 0.4 K after six minutes. The authors conclude current guidelines are insufficient for people with implants and propose regulatory changes.

Numerical analysis of the thermal effects on adult with brain pacemaker implantation exposed to WIFI antennas

Research RF Safe Research Library Jan 1, 2025

This numerical study modeled RF exposure from WiFi/5G-type antennas near a 3D brain model with implanted brain pacemakers relevant to Parkinson’s disease. SAR and temperature increases were reported to remain below ICNIRP 2020 limits across modeled conditions, with maxima at a 90° antenna-to-brain angle. Despite compliance with SAR/temperature limits, the authors report modeled thermal strain and tissue displacement that could affect postoperative efficacy, leading them to recommend caution and increased distance from phones.

Altered development in rodent brain cells after 900 MHz radiofrequency exposure

Research RF Safe Research Library Jan 1, 2025

This animal and in vitro study examined non-thermal 900 MHz RF-EMF exposure during prenatal and postnatal development at 0.08 and 0.4 W/kg SAR. The authors report changes consistent with altered neurodevelopment, including reduced BDNF, reduced in vivo cell proliferation, and disrupted synaptic balance in rat pup brain regions. In vitro, exposed neural stem cells showed increased apoptosis and DNA double-strand breaks and shifts in cell populations toward glial lineages. The authors conclude that regulatory-level 900 MHz exposure can disrupt key neurodevelopmental processes in rodents.

Looking for Biomarkers Which May Explain Idiopathic Environmental Intolerance Attributed to EMF (IEI-EMF): Does RF-EMF Exposure Influence Salivary Cortisol Response?

Research RF Safe Research Library Jan 1, 2025

This randomized, double-blind, counterbalanced provocation study tested whether short-term RF-EMF exposure alters salivary cortisol in 72 predominantly young, healthy adults. Active exposure (2 W/kg peak SAR10g in head) showed no significant effect on cortisol compared with sham, and no sex differences were observed. The authors note that results may not rule out effects in populations not studied and encourage further research into plausible biological interactions.

Impact of in vitro exposure to 5G-modulated 3.5 GHz fields on oxidative stress and DNA repair in skin cells

Research RF Safe Research Library Jan 1, 2025

This in vitro study tested whether 5G-modulated 3.5 GHz RF-EMF exposure affects oxidative stress and DNA repair in human skin cells. Under acute exposure conditions (up to 24–48h) at SARs up to 4 W/kg, the authors report no significant changes in ROS markers, no adaptive response to oxidative challenge, and no impairment of UV-B–related CPD repair via nucleotide excision repair. The authors note that acute in vitro results may not directly generalize to chronic or real-life exposures.
