Bacterial Adaptation to Radiofrequency Electromagnetic Fields Based on Experiences from Ionizing Radiation

Research RF Safe Research Library Jan 1, 2025

This 2025 review summarizes historical and modern literature on how bacteria may adapt to radiofrequency electromagnetic fields from common sources such as mobile phones and Wi-Fi. It argues that RF-EMF exposure can influence bacterial survival mechanisms and could potentially compromise therapeutic interventions by promoting increased resistance. The authors frame these possibilities as a public health concern and call for continued research and precaution.

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.

Extremely Low-Frequency Magnetic Fields (ELF-MF) and Radiofrequency: Risk of Childhood CNS Tumors in a City with Elevated ELF-MF Exposure

Research RF Safe Research Library Jan 1, 2025

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.

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.

The authors also highlight that potential health implications from natural and artificial electromagnetic fields warrant further scientific attention.

The effect of alpha-lipoic acid on liver damage induced by extremely low-frequency electromagnetic fields in a rat model

Research RF Safe Research Library Jan 1, 2025

This rat study assessed whether alpha-lipoic acid (ALA) modifies liver effects from extremely low-frequency magnetic field (ELF-MF) exposure. ELF-MF exposure (2 mT, 4 hours/day for 30 days) was associated with increased liver pathology and higher apoptosis markers (TUNEL, caspase-3) compared with other groups. ALA reduced several histopathological changes and lowered TUNEL/caspase-3, but did not improve fibrosis or biliary proliferation.

A Systematic Review of the Impact of Electromagnetic Waves on Living Beings

Research RF Safe Research Library Jan 1, 2025

This PRISMA-adherent systematic review searched PubMed, Scopus, and the Cochrane Library for studies (2017–2024) on physiological or behavioral responses to EMF exposure, emphasizing studies reporting harmful or concerning effects. Across 24 included studies (human non-randomized, in vitro, and animal), the review reports negative biological effects including oxidative stress, inflammation, genotoxicity, cardiovascular and fertility-related outcomes, neuronal activity changes, and plant photosynthesis impacts. The authors report that most studies had moderate to high risk of bias and therefore the overall certainty of evidence was lower, and they highlight major gaps in long-term human evidence and exposure standardization.

The abstract states that RF-EMR exposure may affect genetic material and suggests a link between EMR exposure and genetic damage, with possible implications for cancer risk and cell death. It also highlights that genetic polymorphisms may modify susceptibility and calls for further research to clarify health impacts.

Carcinogenicity of Radio-Frequency Radiation: Similarities and Differences Between Outcomes of Two Studies

Research RF Safe Research Library Jan 1, 2025

This review compares two epidemiologic studies of radio-frequency radiation (RFR) exposure among military personnel with overlapping patient groups. One study reported a statistically significant increase in cancer among exposed individuals, while the other did not, which the review attributes to a smaller sample size. The review highlights similar cancer patterns across both studies, including a high proportion of hematolymphoid cancers and earlier onset among exposed individuals, and interprets these similarities as evidence of carcinogenic effects.

Prospective long-term follow-up of patients with idiopathic environmental intolerance attributed to electromagnetic fields after a provocation trial

Research RF Safe Research Library Jan 1, 2025

This long-term follow-up recruited participants from an earlier IEI-EMF provocation trial and re-administered the same questionnaire by telephone. Of 70 completers (35 IEI-EMF patients and 35 referents), 62.9% of patients reported recovery after an average of 1.8 years, with most recoveries described as spontaneous. Symptoms and EMF-related concerns generally decreased over time, and the authors suggest IEI-EMF may often be self-limited and consistent with nocebo mechanisms rather than direct EMF effects.

It combines a miniaturized broadband probe, a composite skin-equivalent phantom, and reconstruction/calibration procedures, with validation using reference antennas. The approach is reported as validated for 24–30 GHz and extendable to 10–45 GHz, supporting regulatory-type testing aligned with international safety standards.

In situ electric field dosimetry analysis for powerline frequency peripheral nerve magnetic stimulation

Research RF Safe Research Library Jan 1, 2025

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.

Exposure of human lymphocytes to sweeping-frequency extremely low frequency magnetic field

Research RF Safe Research Library Jan 1, 2025

This in vitro study exposed human umbilical cord blood lymphocytes to a sinusoidal sweeping-frequency ELF magnetic field (3–26 Hz) for 48 hours at amplitudes from 6 to 24 μT. It reports no statistically significant effects on DNA damage/repair foci or apoptosis measures overall. A non-significant trend at 8 μT showed lower γH2AX foci (p = .064) and data suggesting fewer viable cells at the same intensity, which the authors discuss as potentially protective against DNA double-strand breaks.

Magnetic effects in biology: Crucial role of quantum coherence in the radical pair mechanism

Research RF Safe Research Library Jan 1, 2025

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.

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.

Impact of Radiofrequency Electromagnetic Fields on Cardiac Activity at Rest: A Systematic Review of Healthy Human Studies

Research RF Safe Research Library Jan 1, 2025

This systematic review evaluated evidence on RF-EMF exposure and cardiac activity (heart rate and heart rate variability) in healthy humans at rest. Across 28 studies spanning 100 to 110,000 MHz and exposures from minutes to a week, most studies reported no significant effects on resting heart rate, and HRV findings were largely null under calm conditions. Some position-dependent HRV changes were reported, and the authors note possible effects during physiological challenges, but conclude evidence is insufficient for firm conclusions beyond resting healthy populations.

It reports a marked increase in publications in the past five years, with substantial attention to dosimetric metrics (SAR and power density) and their regulatory limits. The authors forecast continued growth in the field and emphasize the need for ongoing research and interdisciplinary collaboration focused on potential health risks and compliance.

Numerical Analysis of Human Head Exposure to Electromagnetic Radiation Due to 5G Mobile Phones

Research RF Safe Research Library Jan 1, 2025

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.

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.

Assessment of Electromagnetic Exposure to a Child and a Pregnant Woman Inside an Elevator in Mobile Frequencies

Research RF Safe Research Library Jan 1, 2025

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.

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.

Weak Radiofrequency Field Effects on Biological Systems Mediated through the Radical Pair Mechanism

Research RF Safe Research Library Jan 1, 2025

This 2025 review examines claims of biological effects from weak, nonthermal RF magnetic fields and evaluates whether such effects could be mediated by the radical pair mechanism (RPM). It reports that aligning RPM theory with low-level experimental observations remains difficult and that many experimental findings are limited by reproducibility, statistical robustness, and dosimetry issues. The authors conclude a tangible but incompletely understood link may exist and emphasize the need for more rigorous, standardized, interdisciplinary work.
