Radiofrequency Electromagnetic Field Emissions and Neurodevelopmental Outcomes in Infants: A Prospective Cohort Study

Research RF Safe Research Library Jan 1, 2025

This prospective cohort study followed 105 neonates/infants for one year and measured household RF-EMF using a selective radiation meter, categorizing exposure into tertiles. Higher household RF-EMF exposure was associated with lower ASQ-3 neurodevelopmental scores, particularly in motor and problem-solving domains, and higher odds of monitor/refer classifications for fine motor and problem-solving. The abstract notes these associations persisted after adjustment for low birth weight, though exposure was measured at a single time point and key confounders (e.g., prenatal phone use, parental interaction) were not assessed.

Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint

Research RF Safe Research Library Jan 1, 2025

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.

Smartphone Usage Patterns and Sleep Behavior in Demographic Groups: Retrospective Observational Study

Research RF Safe Research Library Jan 1, 2025

This retrospective observational study analyzed Murmuras app data from 1074 participants in 2022 to examine demographic differences in smartphone use and nocturnal smartphone inactivity duration (a proxy for sleep-related behavior). Nighttime smartphone use increased, especially for social media and entertainment, and usage patterns varied by gender, age, education, and employment status. Most demographic groups showed no significant correlation between usage duration and nocturnal inactivity, although some subgroups showed correlations in either direction. The authors frame excessive nighttime smartphone use as potentially adverse for sleep and link this behavioral exposure to electromagnetic fields with sleep health risks.

Cluster Analysis of RF-EMF Exposure to Detect Time Patterns in Urban Environment: A Model-Based Approach

Research RF Safe Research Library Jan 1, 2025

This paper applies a model-based clustering approach (Log-Normal Mixture Model) to continuous RF-EMF monitoring data from the Serbian EMF RATEL network in Novi Sad to characterize temporal exposure patterns. The analysis reports separation of night versus day exposure values and identification of daytime periods where exposure persists longer. The work is positioned as supporting improved understanding of when and where elevated exposures occur in urban environments.

Impact of Anthropomorphic Shape and Skin Stratification on Absorbed Power Density in mmWaves Exposure Scenarios

Research RF Safe Research Library Jan 1, 2025

This dosimetry study used FDTD simulations at 28 GHz to evaluate how skin stratification and anthropomorphic modeling affect absorbed power density (APD) estimates. APD was higher with stratified skin than with homogeneous skin for a wearable patch antenna (16%–30% higher), while plane-wave differences were smaller (<11%). The authors argue that simplified skin models may underestimate exposure in mmWave wearable scenarios.

They conclude these findings indicate a safety risk and call for further mechanistic and public health research.

Proteomic Characterization of Human Peripheral Blood Mononuclear Cells Exposed to a 50 Hz Magnetic Field

Research RF Safe Research Library Jan 1, 2025

This in vitro study compared proteomic profiles of PBMCs from three human donors after 24-hour exposure to a 50 Hz, 1 mT extremely low-frequency magnetic field versus unexposed cells. The abstract reports broad protein expression changes, including upregulation of proteins associated with metabolic processes and downregulation of proteins linked to T cell costimulation/activation and immune processes. No effects were observed on cell proliferation, viability, or cell cycle progression. The authors interpret the proteomic shifts as metabolic reprogramming with potential implications for immune regulation.

Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India

Research RF Safe Research Library Jan 1, 2025

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.

Exposure to radiofrequency electromagnetic fields and IARC carcinogen assessment: Risk of Bias preliminary literature assessment for 10 key characteristics of human carcinogens

Research RF Safe Research Library Jan 1, 2025

This review examined experimental literature on whether RF-EMF exposures within ICNIRP (2020) limits affect IARC key characteristics of human carcinogens. It identified 159 articles and found that 38% of in vitro/in vivo measurements reported statistically significant effects, but higher study quality was associated with fewer reported effects and there was no consistent exposure-response pattern. The authors state that study diversity and generally poor quality prevent high-confidence conclusions for most key characteristics, while recommending replication of the few higher-quality positive findings under stringent standards.

Research RF Safe Research Library Jan 1, 2025

This cross-sectional observational study assessed sperm motility after one hour of in vitro exposure of semen samples to EMFs from different laboratory sources in an IVF setting. It reports a statistically significant reduction in progressive sperm motility after exposure to mobile phones and Wi-Fi repeaters, while other EMF-emitting equipment showed no significant effect. The authors interpret the findings as indicating a potential negative impact of specific RF sources and call for further research, alongside practical mitigation suggestions in IVF laboratories.

A novel approach for assessments of radiofrequency electromagnetic fields exposure in buildings near telecommunication infrastructure

Research RF Safe Research Library Jan 1, 2025

This paper proposes a new methodology to better assess indoor RF-EMF exposure in buildings near telecommunication base station antennas by refining measurement-point selection. Implemented in four multi-storey buildings in Natal, Brazil, indoor electric field peaks and averages were reported to be substantially higher than ground-level measurements. Although the highest indoor levels remained below ICNIRP recommended limits, the authors argue current regulatory evaluation methods may underestimate indoor exposure in certain building locations.

Effect of elevation on cumulative radiofrequency exposure from multiple communication towers

Research RF Safe Research Library Jan 1, 2025

This exposure assessment measured RF power density across different floors of a high-rise university building using a spectrum analyser and log-periodic antenna. Power density decreased from the ground to the third floor but peaked on the fourth (top) floor. The 900 MHz band showed the highest reported power density (1.16E-03 W/m2), and the authors suggest higher-floor occupants may experience higher RF exposure from nearby communication towers.

In-Situ Measurements of Radiofrequency Electromagnetic Fields Measurements Around 5G Macro Base Stations in the UK

Research RF Safe Research Library Jan 1, 2025

This exposure assessment performed RF spot measurements in line-of-sight to 56 active 5G macro base stations across 30 publicly accessible UK locations. Power density was measured across 420 MHz–6 GHz under multiple scenarios (background, streaming, downlink speed test, and extrapolated SS-RSRP decoding). Reported total RF and 5G-specific levels were within 1998 ICNIRP public reference levels, with 4G downlink contributing most of the measured exposure.

Protective effects of quercetin against 3.5 GHz RF radiation-induced thyroid dysfunction and oxidative stress in rats

Research RF Safe Research Library Jan 1, 2025

This rat study examined repeated 3.5 GHz RF exposure (2 hours/day, 5 days/week for 30 days) and thyroid-related outcomes, with and without quercetin. The abstract reports altered thyroid hormones (lower T3/T4, higher TSH) and increased oxidative stress in thyroid tissue after RF exposure. Quercetin appeared partially protective, though effects were not uniformly statistically significant, and SAR simulations indicated relatively higher absorption in the thyroid region.

Electromagnetic fields from mobile phones: A risk for maintaining energy homeostasis?

Research RF Safe Research Library Jan 1, 2025

This narrative review discusses low-intensity RF-EMF exposure, primarily from mobile phones, with a focus on thermoregulation and energy homeostasis. It reports that many rodent studies at 900 MHz describe cold-like thermoregulatory and behavioral responses and molecular findings suggestive of WAT browning, while BAT transcriptional changes typical of cold exposure were not observed. The authors indicate short-term adaptations may not disrupt homeostasis, but emphasize uncertainty about long-term consequences and call for further research, including at 5G-relevant frequencies.

Influence of geomagnetic disturbances on myocardial infarctions in women and men from Brazil

Research RF Safe Research Library Jan 1, 2025

This ecological analysis used a public health database of myocardial infarction admissions in São José dos Campos, Brazil (1998–2005) and categorized geomagnetic activity using the planetary Kp index. The abstract reports a higher relative frequency of MI admissions during disturbed geomagnetic conditions compared with quiet periods, with a stronger association in women. Unsupervised k-means clustering reportedly supported the sex-specific pattern.

It emphasizes limited published studies in these exposure ranges and highlights EU-funded initiatives and research consortia aimed at closing knowledge gaps. The authors state that guidelines are generally considered adequate at present, but argue that uncertainties—especially regarding long-term exposure—support continued research and precautionary approaches.

Exposure Perception and Symptom Reporting in Idiopathic Environmental Intolerance Attributed to Electromagnetic Fields Using a Co-Designed Provocation Test

Research RF Safe Research Library Jan 1, 2025

This co-designed provocation study in IEI-EMF volunteers evaluated whether perceived exposure and symptom reporting tracked actual EMF exposure under double-blind conditions. The abstract reports no consistent alignment between perceived exposure certainty or symptoms and true exposure status at the group level, with limited individual exceptions. Symptom reporting was related to certainty of being exposed for about half of participants, which the authors interpret as supporting a nocebo-type mechanism and motivating refinement of provocation protocols.

What is the effect of alarmist media and radiofrequency electromagnetic field (RF-EMF) exposure on salivary cortisol and non-specific symptoms?

Research RF Safe Research Library Jan 1, 2025

This randomized study tested whether viewing alarmist media and participating in an open-label RF-EMF provocation trial influenced non-specific symptoms and salivary cortisol. Participants who believed they were being exposed reported more symptoms than those who believed they were not exposed. The study did not find a replicated effect of alarmist media or open-label RF-EMF exposure on salivary cortisol, suggesting reported symptoms were more related to perception than cortisol-measured stress.
