Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group

Research PubMed: RF-EMF health Feb 2, 2026

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.

Rebuttal to Media Bias Fact Check’s Credibility Assessment of RF Safe

Independent Voices RF Safe Jan 10, 2026

RF Safe publishes a rebuttal to Media Bias Fact Check’s (MBFC) January 8, 2026 credibility assessment, arguing MBFC’s “Medium Credibility” rating is unjustified despite MBFC upgrades to “Least Biased” and “Mostly Factual.” The post disputes MBFC’s criticisms (selective citation, alarmist framing, and potential conflict of interest from product sales) and claims RF Safe’s coverage aligns with WHO-commissioned reviews and legal/regulatory developments. RF Safe reiterates its view that thermal-only RF exposure guidelines are inadequate and calls for policy reform while stating it does not claim definitive human causation.

Measurement of Outdoor Micro-Environmental Radio Frequency Electromagnetic Field Exposure Levels in Daily Life Using a Portable Measurement Device

Research RF Safe Research Library Jan 1, 2026

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.

On exposure-response interpretation and evidence synthesis in low-intensity RF-EMF research

Research RF Safe Research Library Jan 1, 2026

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.

Massive assessment of exposure to 5G electromagnetic fields in France: a 5-year synthesis

Research RF Safe Research Library Jan 1, 2026

This paper reports results from a large-scale, multi-phase measurement campaign in mainland France assessing changes in RF exposure associated with 5G deployment from 2020 to 2024. Using more than 24,000 on-ground measurements in direct view of 5G antennas, it finds small average increases in broadband exposure and increased contributions from 5G-related bands over time. The 3.5 GHz band contribution increased but remained a secondary contributor compared with legacy 800/900 MHz bands, and exposure during active downloading was higher than in idle mode.

Towards a Planetary Health Impact Assessment Framework: Exploring Expert Knowledge and Artificial Intelligence for a RF-EMF Exposure Case-Study

Research PubMed: RF-EMF health Dec 19, 2025

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.

S4-Mito-Spin Framework Assessment

Independent Voices RF Safe Nov 25, 2025

RF Safe presents an assessment of the “S4–Mitochondria–Cryptochrome (S4-Mito-Spin) Framework,” arguing it synthesizes existing peer-reviewed mechanisms to explain reported non-thermal RF/ELF biological effects. The post proposes three linked pillars involving voltage-gated ion channel timing effects, mitochondrial/NOX-driven oxidative stress, and spin-state (radical pair/cryptochrome) chemistry. It frames the framework as a unifying explanation for patterns seen in animal studies while stating it does not make sweeping claims about causing human cancer.

A Density‑Gated, Multi‑Mechanism Framework for Non‑Thermal EMF Bioeffects

Independent Voices RF Safe Nov 24, 2025

RF Safe argues that current RF/ELF safety assessments rely too heavily on a thermal-only paradigm and proposes a “density-gated, multi-mechanism” framework to explain reported non-thermal bioeffects. The article claims weak EMFs could couple into biology via voltage-gated ion channel (VGIC) mechanisms and radical-pair/spin-chemistry pathways, with tissue vulnerability depending on the density of relevant biological structures. It cites several external studies and reviews (e.g., NTP/Ramazzini rodent bioassays, WHO-commissioned reviews, and selected cellular studies) as “anchors,” while presenting the overall model as a unifying explanation rather than a single new experiment.

Towards a Planetary Health Impact Assessment Framework: Exploring Expert Knowledge & Artificial Intelligence for RF-EMF Exposure Case-Study

Research RF Safe Research Library Jan 1, 2025

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.

Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study proposes and validates a method to measure instantaneous RF exposure under typical base station load by generating defined data rates (low/medium/high) using iPerf and measuring channel power across services. Validation at four base stations suggests the approach is reliable across different times of day and loads, with reproducible results when averaging over 30 sweeps. Comparisons indicate iPerf-provoked constant data rates generally match exposure during real application usage, with few deviations beyond stated uncertainty.

Assessment of Electromagnetic Field Exposure from Multiple Sources Simultaneously in the High- Frequency Range Based on Safety Standards

Research RF Safe Research Library Jan 1, 2025

This conference paper proposes a method to assess combined EMF exposure from multiple simultaneous high-frequency sources using a normalized exposure ratio based on ICNIRP 2020 guidelines. It emphasizes a current gap in standardized absorbed power density (Sab) measurement above 10 GHz and proposes incident power density (Sinc) as a temporary surrogate. The work is framed as supporting compliance verification and safety measure design, with a stated need for future experimental validation and standardization.

Analysis of Actual Transmitted Power from Hundreds of 5G FR2 Radio Base Stations over One Month in Urban Areas in Japan

Research RF Safe Research Library Jan 1, 2025

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.

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.

RF-EMF Exposure Assessment: Comparison of Measurements in Airports and Flights with and Without Wi-Fi Service

Research RF Safe Research Library Jan 1, 2025

This exposure assessment used personal exposimeters to measure RF-EMF levels in the 2.4 GHz and 5.85 GHz Wi-Fi bands in airport terminals and during four international flights, including flights with and without onboard Wi-Fi service. Reported mean exposures varied by route but were described as substantially below an international reference level (10 W/m²). The authors conclude exposure is low while also recommending ongoing monitoring and precaution due to potential health concerns mentioned as emerging evidence.

Exposure Variability Between 1- or 6-Minute and 30-Minute Averaging Time Lengths in Radiofrequency-Electromagnetic Field Exposure Monitoring

Research RF Safe Research Library Jan 1, 2025

This exposure assessment study compared RF-EMF measurements averaged over 1, 6, and 30 minutes using contiguous 1-minute data collected over 30 minutes at four indoor/outdoor sites across 15 frequency bands. Relative deviations between shorter averaging times and 30-minute averages were largely within ±3 dB. However, statistical comparisons of overall exposure variability between 1- or 6-minute and 30-minute averaging produced inconsistent results, with broadcast and most mobile services <2 GHz appearing broadly similar between 1- and 6-minute averaging.

Visualizing radiofrequency electromagnetic field exposure through Voronoi-based maps

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study proposes a Voronoi-diagram approach to visualize RF-EMF exposure across a city using personal exposimeter measurements of RMS electric field at seed points. Most mapped areas corresponded to about 1.9 V/m, with a maximum reported value of 11.4 V/m, all below the cited ICNIRP guideline level. The authors conclude the method is useful for communicating spatial variability, while also noting broader literature discussing potential health risks from EMF exposure.

Research RF Safe Research Library Jan 1, 2025

This engineering/monitoring paper describes enhancements to the Serbian EMF RATEL system, which has continuously monitored RF-EMF since 2017, by adding drive test functionality to improve spatial coverage. The authors report preliminary quantitative drive test measurements and validation of the upgraded approach. The work emphasizes that characterizing spatial and temporal RF-EMF patterns can support exposure assessment relevant to public health risk evaluation.

Associations between Individual and Geospatial Characteristics and Power of 4G Signals Received by Mobile Phones

Research RF Safe Research Library Jan 1, 2025

This exposure assessment study analyzed smartphone-logged 4G LTE RSSI and GPS data from adults in France to identify determinants of downlink signal strength. RSSI varied with geospatial factors (distance to antennas, antenna density, urbanicity) and time of day, and was also influenced by technical smartphone parameters. The study reports an estimated electric field strength derived from RSSI, but notes high uncertainty in this conversion.

Assessment of Electromagnetic Exposure Levels for Humans from Electric Vehicle DC Charging Stations

Research RF Safe Research Library Jan 1, 2025

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.

Evaluation of Exposure Assessment Methods and Procedures for Induction Hobs (Stoves)

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study evaluated magnetic-field and contact-current exposures from modern induction hobs using IEC-based measurement procedures, 3D field scanning, and numerical dosimetry in anatomical models. It reports large between-hob variability in exposure and states that IEC 62233 may substantially underestimate user exposure. The authors argue that design modifications can reduce exposure and that product standards should be revised to better reflect realistic user scenarios.

Systematic reviews and meta-analyses for the WHO assessment of health effects of exposure to radiofrequency electromagnetic fields, an introduction

Research RF Safe Research Library Jan 1, 2025

This editorial introduces a special issue supporting the WHO assessment of health effects from RF-EMF exposure, based on nine protocols and twelve systematic reviews developed over four years by more than 80 experts. It summarizes that human evidence for major cancers was moderate-certainty for no or only small effects, with lower certainty for some cancer sites, while animal evidence reported higher-certainty effects for several cancer types and adverse effects on male fertility. For cognition, symptoms, and oxidative stress, certainty was generally lower and findings more variable, and the editors note ongoing methodological challenges and the possibility of unidentified mechanisms.

Dual Evaluation and Spatial Analysis of RF-EMF Exposure in 5G: Theoretical Extrapolations and Direct Measurements

Research RF Safe Research Library Jan 1, 2025

This exposure assessment study evaluated 5G RF-EMF exposure using both theoretical extrapolations and direct measurements in semiurban and urban settings, including a campus case study. Measured and extrapolated exposure levels were reported to be within ICNIRP recommended limits, even under high network data demand. The authors also report a strong correlation between theoretical and instantaneous field exposures, supporting the validity of their dual-method framework.

Assessment of 5G RF-EMF Exposure during Large-Scale Public Events via Field Measurements

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study conducted field measurements of 5G downlink RF-EMF during a large public festival in Valencia, Spain, and compared them with a baseline day. Measurements covered 700 MHz and 3500 MHz bands across three network operators and five locations, using 6-minute and 30-minute durations. The study reports higher event-related power density (up to eightfold at 3500 MHz) but states that all measured levels remained well below international safety limits.

5G RF EMF Spectral Exposure Assessment in Four European Countries

Research RF Safe Research Library Jan 1, 2025

This exposure assessment used 146 indoor and outdoor spot measurements in 2023 across Belgium, Switzerland, Hungary, and Poland to characterize 5G (3.6 GHz) and cumulative RF EMF incident power density in public spaces and educational institutions. Reported maximum 5G-specific incident power density was 10.4 mW/m2 (3.2% of the frequency-specific ICNIRP guideline), and all measured levels were stated to be well within ICNIRP limits. Rural areas showed significantly lower incident power density than urban areas, and LOS conditions had higher average incident power density than NLOS. The authors recommend continued reassessment as 5G coverage expands.

Assessment of spatial-average absorbed power density and peak temperature rise in skin model under localized electromagnetic exposure

Research RF Safe Research Library Jan 1, 2025

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.
