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.
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.
Measurement of Outdoor Micro-Environmental Radio Frequency Electromagnetic Field Exposure Levels in Daily Life Using a Portable Measurement Device
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.
Massive assessment of exposure to 5G electromagnetic fields in France: a 5-year synthesis
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.
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.
Development and Testing of a Novel Whole-body Exposure System for Investigative Studies of Radiofrequency Radiation in Rodents (NIEHS)
This NIEHS report describes the development and testing of a flexible whole-body radiofrequency radiation exposure system for rats and mice using updated signals relevant to wireless technologies. In 5-day studies with CDMA- and GSM-modulated signals, no visible behavioral responses were observed and comet assays reported no DNA damage in multiple tissues. The report notes technical challenges, particularly difficulty obtaining reliable body temperature measurements during exposure, and positions the system as a prototype for future mechanistic toxicology studies.
Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station
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
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.
RF-EMF Exposure Assessment: Comparison of Measurements in Airports and Flights with and Without Wi-Fi Service
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
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
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.

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

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
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
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.

This paper presents a quantitative framework for selecting extremely low-frequency electromagnetic field (ELF-EMF) measurement instruments. It uses a weighted scoring matrix across six criteria and a logic-based flowchart to guide instrument choice based on operational needs. The framework is demonstrated in an occupational case study and is positioned as supporting transparent, adaptable device selection for occupational safety and public health.

This microenvironmental measurement study assessed temporal trends in outdoor RF-EMF exposure between 2016 and 2023 in the Netherlands, Switzerland, Belgium, and Spain using harmonized walking-route measurements with exposimeters. The authors report no significant change in mobile base station (downlink) exposure between 2016 and 2023 and no consistent trend across microenvironments or countries. Reported median downlink exposure values ranged from 0.11 mW/m² (Switzerland, 2023) to 0.62 mW/m² (Netherlands, 2018).

This exposure-assessment study compares RF-EMF exposure maps produced using a broadband meter versus a personal exposimeter and aims to correct personal exposimeter readings to match broadband-based maps. The authors report that LOS/NLOS-specific correction factors reduce discrepancies, particularly improving LOS measurements affected by body shielding. A genetic algorithm is used to optimize correction factors and support scalable urban exposure mapping, with the authors noting that additional validation in other environments is needed.

This paper presents a machine-learning method to estimate ground-level electromagnetic radiation (electric field strength) in the near field of 5G base stations, using multiple technical and environmental input parameters. The authors report experimental performance with a mean absolute percentage error of about 5.89% and suggest the approach can reduce costs compared with on-site measurements. The work is positioned as supporting exposure management and base-station placement, while noting the need for careful EMF management due to potential health-risk links.

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.
Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India
This cross-sectional study compared 183 higher-exposed residents with 126 matched reference residents and assessed symptoms via questionnaire alongside in-home RF-EMF power density measurements from mobile phone base stations. Higher exposure (including proximity within 50 m and power densities of 5–8 mW/m2) was reported to be associated with increased symptom prevalence across mood-energy, cognitive-sensory, inflammatory, and anatomical categories. The authors conclude that current public exposure limits may be inadequate for long-term, non-thermal biological impacts and call for precautionary policy updates.
