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.
The effects of short-term and long-term 2100 MHz radiofrequency radiation on adult rat auditory brainstem response
This animal study examined 2100 MHz radiofrequency radiation exposure effects on auditory brainstem responses and brain oxidative/ultrastructural markers in adult rats. The 1-week exposure group showed prolonged ABR latencies and biochemical/structural changes consistent with oxidative stress and cellular injury. The authors report no harmful effects in the 10-week exposure condition with rest days under the studied protocol.
Electromagnetic fields from mobile phones: A risk for maintaining energy homeostasis?
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.
Characterization of the Core Temperature Response of Free-Moving Rats to 1.95 GHz Electromagnetic Fields
This animal study measured core body temperature in free-moving male and female Sprague Dawley rats during and after 3-hour exposure to 1.95 GHz RF-EMF at multiple whole-body average SAR levels. A measurable thermal response was reported at 4 W/kg, while lower SAR conditions showed smaller or no significant temperature increases. The authors note that temperature dropped quickly after exposure ended, implying post-exposure measurements may underestimate peak heating.
The Influence of an Electromagnetic Field at a Radiofrequency of 900 MHz on the Behavior of a Honey Bee
This laboratory study examined whether a 900 MHz radiofrequency electromagnetic field (RF-EMF) influences the behavior of newly emerged honey bee workers. Compared with controls, the exposed groups showed behavioral changes, with some parameters showing statistically significant differences seven days after exposure. The authors frame RF-EMF as a potential environmental stressor and call for further research, including gene expression analyses.
Mitigation of 3.5 GHz Electromagnetic Field-Induced BV2 Microglial Cytotoxicity by Polydeoxyribonucleotide
This in vitro study exposed BV2 mouse microglial cells to 3.5 GHz EMF for 2 hours and reports reduced cell growth and increased apoptosis alongside oxidative stress and signaling changes. The authors report that ROS generation and activation of JNK-1/2 and p38 MAPK were key events in the observed cytotoxicity. Polydeoxyribonucleotide (PDRN) reportedly reduced several EMF-associated cytotoxicity markers, suggesting a potential mitigating effect under the tested conditions.
The influence of Wi-Fi on the mesonephros in the 9-day-old chicken embryo
This animal study examined continual 2.4 GHz Wi‑Fi exposure (200–500 μW/m²) during 9 days of chicken embryo incubation and assessed the mesonephros at day 9. The authors report no adverse effects on general mesonephros development, but describe moderate degenerative changes and vascular congestion without inflammatory infiltrate. They also report significantly increased apoptotic and proliferating cells and up-regulation of caspase‑1 gene expression, interpreted as disruption of regulatory processes during development.
The proliferation rates of HT-1080 human fibrosarcoma cells can be accelerated or inhibited by weak static and extremely low frequency magnetic fields
This in vitro study exposed HT-1080 human fibrosarcoma cells for 4 days to weak extremely low frequency magnetic fields (10 μT, 12–33 Hz) superimposed on a 45 μT static field. The authors report frequency- and amplitude-dependent increases or decreases in cell growth, including sharp inversions near 16.5 Hz with small parameter changes or reversal of the static field direction. Associated changes in membrane potential, intracellular calcium, and mitochondrial superoxide are presented as supporting a bioenergetic mechanism.
Impact of magnetic fields from tablets, laptops, smartphones, and household/leisure magnets on cardiac implantable electronic devices
This study tested magnetic fields from tablets, laptops, smartphones, and household/leisure magnets against 13 cardiac implantable electronic device (CIED) models to assess magnet mode activation. It reports that these consumer devices can trigger magnet mode when in close proximity, with median activation distances of 5–6.5 mm for phones/tablets/laptops and mainly contact-level activation for household/leisure magnets. None of the tested devices activated magnet mode at distances of 20 mm or more, and the authors emphasize patient awareness of proximity-related risk.
SAR Estimations in a Classroom with Wireless Computers
This study simulated 1 g and 10 g peak spatial SAR (psSAR) in classroom settings where each student uses a Wi‑Fi laptop at 2.45 GHz and 100 mW. Maximum simulated psSAR values were reported to be below ICNIRP and IEEE recommended limits, but desk spacing and multi-user configurations could substantially increase psSAR compared with a single-user setup. The authors emphasize that long-term low-level exposure, particularly for children, remains a concern and recommend mitigation via increased spacing and wired connections.
Bus-exposure matrix, a tool to assess bus drivers' exposure to physicochemical hazards
This paper describes the development of a Bus-Exposure Matrix (BEM) to retrospectively estimate Swiss bus drivers’ exposures to 10 physicochemical hazards, including electric and magnetic fields. Measurements in representative buses were combined with technical inventories and INLA modeling to estimate annual exposures from 1985–2022. Reported trends include increasing peak noise and electric-field exposures over time, alongside decreases in several air pollution, vibration, and noise metrics.
Human achromatic flickers and phosphenes thresholds under extremely low frequency electric stimulations
This study estimated thresholds and locus for human phosphene perception during non-invasive transcranial alternating current stimulation at 20, 50, 60, and 100 Hz. Perception depended significantly on stimulation intensity, with the lowest threshold at 20 Hz and no reported phosphenes at 100 Hz. The authors report dosimetry consistent with a retinal origin and frame the findings as relevant for informing cautious ELF exposure limits in safety guidelines.
Influence of geomagnetic disturbances on myocardial infarctions in women and men from Brazil
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.
Effects of Polarized Coherent Microwaves Modulated at Extremely Low Frequencies
This review-style text discusses polarized, coherent microwaves that are modulated and pulsed at extremely low frequencies (ELF) and suggests these characteristics may increase biological interactions. It emphasizes that intensity variability and ELF modulation are important for understanding EMF–biology interactions. It also states that such exposures have been linked to health risks in the scientific literature, framing the topic as relevant to EMF safety and public health risk mitigation.
A comprehensive mechanism of biological and health effects of anthropogenic extremely low frequency and wireless communication electromagnetic fields
This narrative review discusses biological mechanisms and reported health effects of anthropogenic extremely low frequency (ELF) and wireless communication (WC) electromagnetic fields. It highlights oxidative stress and DNA damage as key mechanistic endpoints and proposes an IFO-VGIC pathway linking EMF exposure to ROS overproduction and cellular dysfunction. The authors interpret the broader literature as indicating risks (e.g., cancer, infertility, EHS) even below current exposure limits and advocate precautionary policy measures, including stricter limits and a 5G moratorium.
Rapid Deployment of 5G Wireless Communication and Risk Assessment on Human Health: Quid Novi?
This review discusses the rapid deployment of 5G and the associated debate about potential human health impacts from EMF exposure, particularly at 3.5–26 GHz including millimeter waves. 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.
5G-exposed human skin cells do not respond with altered gene expression and methylation profiles
This in vitro study exposed human skin cells (fibroblasts and keratinocytes) to 5G-band electromagnetic fields for 2 hours and 48 hours using a fully blinded design. Exposures were up to ten times permissible limits, with sham exposure as a negative control and UV exposure as a positive control. The study reports that observed gene expression and DNA methylation differences were minor and consistent with random variation, supporting no detectable EMF-related effect under the tested conditions.
Impact of mobile phone-emitted non-ionizing electromagnetic radiation on parotid gland function: A comprehensive study
This cross-sectional study of 104 university student volunteers assessed whether mobile phone-emitted non-ionizing electromagnetic radiation is associated with changes in parotid gland-related salivary measures. The authors report higher salivary flow rate and pH with longer mobile phone usage duration, along with side-related differences in albumin, IMA, and IMAR. The paper concludes that consistent exposure to mobile phone NIER and associated heat adversely affects parotid gland function and frames this as a health risk, while calling for further long-term research.
Epidemiological criteria for causation applied to human health harms from RF-EMF exposure: Bradford Hill revisited
This paper is a commentary reviewing how Bradford Hill’s epidemiological criteria can be applied to multidisciplinary evidence on RF-EMF exposure and adverse health effects. It reports that systematic reviews and meta-analyses in this area often reach substantially different conclusions, and argues that key weaknesses in primary studies—especially exposure measurement error and insufficient time for long-latency tumors—help explain the divergence. The author suggests these limitations may cause underestimation of potential causation if the associations are truly causal, and calls for independent guidelines to improve future epidemiological research quality.
Skin Fibroblasts from Individuals Self-Diagnosed as Electrosensitive Reveal Two Distinct Subsets with Delayed Nucleoshuttling of the ATM Protein in Common
This study reports on 26 adults self-diagnosed with electromagnetic hypersensitivity (EHS) who provided skin biopsies to generate primary fibroblast lines. The authors describe two EHS subsets based on questionnaire and DNA damage-related measures, and report delayed ATM nucleoshuttling after X-ray exposure in all samples, interpreted as impaired DNA repair signaling. They propose a molecular model linking EHS to ATM pathway dysfunction and suggest this could relate to increased cancer risk or accelerated aging.
