This RF Safe article argues that everyday electromagnetic fields (EMFs) could act as a weak “magnetic co‑zeitgeber,” subtly influencing circadian timing alongside light. It proposes a mechanism in which EMFs modulate cryptochrome radical‑pair spin dynamics, potentially nudging circadian phase and downstream processes such as melatonin rhythms, immune function, epigenetic programming, and DNA repair. The piece presents the idea as a framework with testable implications while acknowledging uncertainties, but it is primarily explanatory/commentary rather than reporting new study results.
A Root-Cause Hypothesis for Non-Native EMFs as Entropic Waste
An RF Safe article presents a personal narrative and hypothesis that “non-native EMFs” act as “entropic waste” that could disrupt early embryonic neurodevelopment (neurulation), potentially contributing to neural-tube defects and later neurodevelopmental outcomes such as autism/ADHD. The author links a family tragedy to this hypothesis and argues for reducing wireless exposure as a precaution. The post cites several studies/reports (e.g., Farrell 1997, Aldad 2012, NTP 2018, WHO SR4A 2025) but does not provide detailed methods or evidence appraisal within the excerpt.
The Herzification / Bioelectric Fidelity Hypothesis
RF Safe presents the “Herzification / Bioelectric Fidelity Hypothesis,” arguing that modern RF/EMF exposure has rapidly altered the human electromagnetic environment and may degrade biological electrical signaling (“bioelectric fidelity”). The post frames this as an “evidence-anchored hypothesis” that could help explain a wide range of outcomes (e.g., cancer, infertility, ADHD-like traits, some autism phenotypes, emotional dysregulation), while acknowledging it is not definitive proof. It also cites Heinrich Hertz’s illness as a suggestive historical anecdote and references proposed non-thermal interaction mechanisms involving voltage-gated ion channels.
Restoring Bioelectric Timing Fidelity to Prevent Immune Dysregulation
RF Safe publishes a mechanistic white-paper-style post arguing that pulsed/low-frequency components of RF exposure could introduce “phase noise” into voltage-gated ion channel (VGIC) voltage sensors (S4), degrading the timing of membrane potentials and calcium (Ca²⁺) oscillations that immune cells use for activation and tolerance decisions. The post claims such timing disruption could mis-set immune thresholds, promote inflammation, and trigger mitochondrial ROS and mtDNA release that sustains a feed-forward inflammatory loop. It frames reported tumor patterns in animal bioassays (e.g., cardiac schwannomas, gliomas) as consistent with this proposed “timing-fidelity” mechanism, while acknowledging competing views on whether RF at current limits can couple to VGICs.
Towards a Planetary Health Impact Assessment Framework: Exploring Expert Knowledge & Artificial Intelligence for RF-EMF Exposure Case-Study
This paper presents a case study proposing a Planetary Health Impact Assessment (PHIA) framework for RF-EMF exposure from mobile telecommunication technologies using knowledge graphs. Twelve experts co-developed knowledge graphs to visualize potential direct effects on organisms and indirect effects on humans via ecosystem disruption, while an AI/NLP tool was used to extract and visualize literature with required expert validation. The authors highlight substantial evidence gaps on ecological impacts (e.g., pollinators, birds, plants) and emphasize the possibility of indirect health risks mediated through ecosystems.
Personal radio use and risk of cancers among police officers in Great Britain: Results from the airwave health monitoring study
This prospective cohort analysis from the Airwave Health Monitoring Study evaluated whether occupational personal radio (TETRA) use is associated with cancer risk among 48,457 police officers and staff. Over a median 11 years of follow-up, the study reports no association with all cancers or with head/neck/CNS cancers, and no evidence of a non-linear dose-response with call duration. The authors emphasize that confidence intervals were wide and that a modestly increased risk at high usage cannot be ruled out, supporting continued monitoring.
Evidence on RF-EMF and cancer in animals misjudged: methodological and analytical flaws in the Mevissen et al. systematic review
No abstract was provided. From the title and supplied overview, this paper critiques the Mevissen et al. systematic review on RF-EMF exposure and cancer in animal studies, asserting that methodological and analytical flaws led to misjudgment of the evidence. The provided text frames the topic as requiring careful analysis to avoid underestimating potential health risks.
Analysis of Actual Transmitted Power from Hundreds of 5G FR2 Radio Base Stations over One Month in Urban Areas in Japan
This exposure/compliance assessment study collected 5- and 30-minute transmitted power data over one month from more than 400 5G FR2 beamforming base stations in urban Japan to evaluate the IEC 62232:2025 “actual maximum approach.” All measured transmitted powers were below configured maxima, with 30-minute averaged normalized maxima reported as < -8 dB, while 5-minute averaged maxima reached about -3 dB under low UE counts. The authors report that the actual maximum approach can avoid overestimation for longer averaging times, but may underestimate exposure for stations with three or fewer UEs if power is not monitored and controlled.
Thermal and SAR-Based Limits for Human Skin Exposed to Terahertz Radiation
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.
Experience of Polish Physicians on Electromagnetic Hypersensitivity
This cross-sectional questionnaire study surveyed 355 Polish physicians about EMF health effects and electromagnetic hypersensitivity (EHS). Physicians reported limited knowledge and low familiarity with WHO guidance for managing people who believe they are hypersensitive to EMF, though most were willing to learn more. Many physicians reported encountering patients attributing symptoms to EMF, which the authors frame as highlighting a need for improved physician education and reliable public information.
Extremely Low-Frequency Magnetic Fields (ELF-MF) and Radiofrequency: Risk of Childhood CNS Tumors in a City with Elevated ELF-MF Exposure
This case-control study in Mexico City (2017–2022) evaluated residential ELF-MF and device-use proxies for RF exposure in relation to childhood CNS tumor risk. Elevated residential ELF-MF (≥0.4 μT) was associated with approximately doubled odds of CNST, while cell phone use showed no association. Prolonged tablet use, with or without internet connectivity, was reported to be associated with higher CNST risk.
Dosimetric Electromagnetic Safety of People With Implants: A Neglected Population?
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
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.
Assessment of Electromagnetic Exposure Levels for Humans from Electric Vehicle DC Charging Stations
This simulation study modeled EMF exposure from an electric vehicle DC charging pile transformer using adult and child human models at several distances and for in-vehicle occupants during charging. Reported peak B-field and E-field values at 0.1 m and modeled internal exposures decreased with distance and remained below stated ICNIRP occupational and public limits. Frequency comparisons (85–95 kHz) indicated decreasing B-field with higher frequency while E-field stayed relatively stable. The authors note the need for real-world measurement validation and further assessment in sensitive populations and multi-source settings.
Female Crabs Are More Sensitive to Environmentally Relevant Electromagnetic Fields from Submarine Power Cables
This controlled laboratory study examined sex-specific behavioral responses of juvenile shore crabs to magnetic fields intended to represent submarine power cable EMFs. Females showed consistent attraction to EMF-exposed zones across 500–3,200 μT exposures, whereas males showed no consistent spatial preference. The authors suggest such sex-specific sensitivity could disrupt female-driven behaviors relevant to migration and reproduction, with potential ecological implications.
Oxidative stress and testicular damage induced by chronic exposure to 35.5 GHz millimeter wave radiation in male Wistar rats
This randomized controlled animal study examined chronic 35.5 GHz millimeter wave exposure in male Wistar rats (2 hours/day for 60 days) compared with control and sham groups. The exposed group showed reduced sperm count and viability along with testicular histopathological changes. Oxidative stress markers shifted toward increased lipid peroxidation and reduced antioxidant defenses, and comet assay results indicated increased DNA damage.
Assessment of spatial-average absorbed power density and peak temperature rise in skin model under localized electromagnetic exposure
This numerical dosimetry study modeled localized RF exposure (3–30 GHz) in multi-layer human skin constructs including skin, fat, and muscle, with an added synthetic blood vessel model. Vascular modeling had negligible impact on peak spatial-averaged absorbed power density and a modest impact on peak temperature rise (about 8% at 3 GHz, <3% above 6 GHz). The authors conclude that including vasculature can refine predictions of localized thermal distributions for dosimetry accuracy.
Assessing exposure from different vehicular antennas in military applications: a computational study
This computational study modeled electromagnetic exposure for military personnel near vehicular communication antennas across HF, VHF, and UHF scenarios. All simulated configurations reportedly met ICNIRP Basic Restrictions, though some exceeded ICNIRP Reference Levels in certain positioning and frequency combinations. The authors conclude that safety is generally maintained across the modeled conditions and that results can inform operational guidance and safety regulations.
In situ electric field dosimetry analysis for powerline frequency peripheral nerve magnetic stimulation
This study used computational dosimetry to analyze induced electric fields in a realistic human body model for a 60 Hz magnetic-field exposure system targeting the leg. Simulations indicated high EF intensities in several leg nerves and modeled conditions consistent with possible peripheral nerve stimulation. The MRG model produced lower stimulation thresholds than the SENN model, and nerve orientation was reported as a key determinant of stimulation risk.
Magnetic effects in biology: Crucial role of quantum coherence in the radical pair mechanism
This theoretical biophysics study models the radical pair mechanism as an open quantum system to derive an explicit dependence of magnetic-field effects on the spin coherence relaxation time (τ) and chemical kinetics (k). It reports a condition under which RPM effects become significant and estimates τ in cryptochrome-like proteins to be on the order of units to tens of nanoseconds. The paper also reports that nanoTesla-level radio-frequency fields have minor influence and are unlikely to disrupt RPM patterns under the modeled decoherence.
Comparative Analysis of Beamforming Techniques and Beam Management in 5G Communication Systems
This engineering paper reviews and classifies beamforming techniques in 5G New Radio and examines beam management procedures at Layer 1 and Layer 2. It analyzes the spectral spectrogram of Synchronization Signal Blocks (SSBs) to illustrate how configuration parameters influence spectral occupancy and synchronization-related performance in different deployment scenarios, including FR2. The work is framed as technical optimization, with only a general note that such knowledge may inform safety considerations related to EMF exposure.
Numerical Analysis of Human Head Exposure to Electromagnetic Radiation Due to 5G Mobile Phones
This conference paper uses numerical simulations to evaluate near-field exposure and thermal effects in a detailed human head model from a realistic 5G mobile phone operating at 26 GHz. The preliminary modeling suggests moderate, localized temperature increases in superficial tissues. The authors emphasize the need for higher-resolution models, refined tissue segmentation, longer exposure durations, and varied phone placements to better characterize potential impacts.
Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint
This viewpoint reports results from a pilot questionnaire survey of 142 self-declared EHS/IEI-EMF individuals and argues that current evidence and tools do not allow a definitive medical diagnosis of sensitivity to low-level wireless radiation. It notes that many reported diagnoses appear anecdotal and that tests used lack scientific proof for detecting such sensitivity. The article also considers individual sensitivity plausible and calls for controlled provocation and biochemical studies to develop diagnostic biomarkers.
Assessment of Electromagnetic Exposure to a Child and a Pregnant Woman Inside an Elevator in Mobile Frequencies
This study uses anatomically detailed computational models of a five-year-old girl, a pregnant woman in the third trimester, and a fetus to simulate mobile phone RF exposure inside an elevator cabin. Simulations at 1000 MHz and 1800 MHz across 48 configurations evaluated SAR10g, whole-body SAR, and maximum temperature. The abstract reports that configuration (positioning and phone orientation) can substantially change absorption and temperature metrics and calls for broader scenario testing to inform safety guidance for vulnerable populations.
Perspectives on terahertz honeybee sensing
This paper describes measurements and simulations to support terahertz (THz) sensing of European honey bees for environmental monitoring. It reports dielectric characterization of bee body parts across 1–500 GHz, scattering-based validation of 3D-printed bee mockups, and THz imaging demonstrating detailed anatomical visualization. The work includes dosimetric simulations at 300 GHz to evaluate feasibility of non-invasive, continuous monitoring and notes potential relevance to assessing high-frequency EMF impacts on insect health and habitat safety.
