140 postsPilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint
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.
Analysis of Human Exposure to Electric and Magnetic Fields While Charging and Driving an Electric Vehicle
This paper describes planned experimental measurements of electric and magnetic fields generated by electric vehicles during charging and driving. The abstract emphasizes that occupants can experience notable EMF exposure due to proximity to vehicle electrical systems, while stating that specific health risks in the EV context remain uncertain. It also notes that manufacturers implement technological design solutions intended to reduce exposure.
Effect of the radiation emitted from a cell phone on T lymphocytes in mice
This mouse study examined whether cell phone radiation affects T lymphocytes over 2–8 weeks of exposure. CD4 and CD8 subset percentages were similar across groups, but after more than six weeks, exposed groups showed increased T-cell apoptosis and reduced transformation rates compared with shams. The study also reports decreased IL-10 and increased IL-12 in exposed groups, suggesting time-dependent immunological changes under the tested conditions.
Single-cell analysis reveals the spatiotemporal effects of long-term electromagnetic field exposure on the liver
This animal study exposed mice to 2.45 GHz electromagnetic fields daily for up to 5 months and assessed liver effects using serum tests, lipidomics, histology, and single-cell/spatiotemporal transcriptomics. The authors report that hepatic cell types differed in sensitivity, with hepatocytes, endothelial cells, and monocytes showing notable transcriptomic disruptions. Reported changes involved lipid metabolism and immune regulation and were spatially enriched in peri-portal liver regions. The authors frame the findings as evidence of significant biological impacts on the liver from long-term EMF exposure.
Investigation of the Effects of 2.45 GHz Near-Field EMF on Yeast
This in vitro study exposed yeast suspensions to 2.45 GHz near-field microwave radiation at 2 cm and 4 cm for 20 or 60 minutes. It reports oxidative-stress-related changes (reduced antioxidant activity with increased membrane permeability) after 20 minutes at 2 cm, an effect not reproduced by conventional heating. The study also reports a trend toward increased DNA damage under both exposure conditions and mild membrane permeability changes after 60 minutes at 4 cm.
Low frequency magnetic field exposure and neurodegenerative disease: systematic review of animal studies
This systematic review synthesizes animal studies on low frequency magnetic field exposure in relation to neurodegenerative diseases. It reports no support for a causal induction of Alzheimer’s-type neuropathology in naive animals, while noting that evidence is too limited to draw strong conclusions for motor neuron disease, multiple sclerosis, and Parkinson’s disease regarding induced neuropathology. In models with pre-existing neurodegenerative disease, the review describes possible therapeutic effects on behavioral and neuroanatomical outcomes for dementia-related conditions, and no apparent effect on motor neuron disease progression.
13.56 MHz RFID Module - From Application to Process Modelling and Effects on Human Health
This paper presents an application and numerical process modelling of a 13.56 MHz RFID module, including how nearby tags/cards and their positioning affect antenna characteristics. It also considers RFID operation near human tissues and discusses potential health impacts from prolonged EMF exposure at 13.56 MHz. The authors emphasize the importance of evaluating long-term exposure risks and call for additional scientific attention.
5G Radio-Frequency-Electromagnetic-Field Effects on the Human Sleep Electroencephalogram: A Randomized Controlled Study in CACNA1C Genotyped Volunteers
This randomized, double-blind, sham-controlled study tested whether CACNA1C rs7304986 genotype modifies sleep EEG responses to 5G RF-EMF exposure. The authors report a genotype-by-exposure interaction, with 3.6 GHz exposure in T/C carriers associated with a faster NREM sleep spindle center frequency versus sham. The abstract also notes longer sleep latency in T/C compared with T/T carriers, and concludes that genetically susceptible groups may show differential physiological responses to 5G RF-EMF.
Evaluation of Personal Radiation Exposure from Wireless Signals in Indoor and Outdoor Environments
This exposure assessment measured personal RF electric field strength in multiple indoor and outdoor micro-environments in Malaysia using an ExpoM-RF 4 meter and modeled exposure with machine learning (FCNN, XG Boost) and linear regression. Reported exposures were usually below the stated public limit (61.4 V/m), but maximum values in dense urban areas with many base stations were reported to approach 56.7365 V/m. The authors frame near-threshold maxima in high-density areas as a potential health risk and recommend caution and monitoring.
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.
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.
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.
Assessing RF EMF exposure in multiple microenvironments across ten European countries with a focus on 5G
This exposure assessment measured environmental and auto-induced RF-EMF across more than 800 microenvironments in ten European countries, with a focus on 5G-related bands. Non-user environmental exposure was reported to be below international guideline values and similar to prior European research, while induced traffic substantially increased measured exposure, especially in uplink scenarios. The study also reports systematic differences by setting (cities vs villages) and by national precautionary limit policies.
Active matter as the underpinning agency for extraordinary sensitivity of biological membranes to electric fields
This biophysics paper presents a nonequilibrium (active matter) statistical mechanics model for electromechanical biological membranes. It argues that energy-driven activity in membranes could enable detection of electric fields far below equilibrium thermal-noise limits, and reports that the model can reproduce experimental observations by tuning activity. The abstract frames this as a potential mechanistic link between weak electromagnetic fields and biological responses, while also noting future modeling directions and possible implications for exposure safety discussions.
Impairment of Oogenesis and Folliculogenesis in Neonatal Rats after Maternal Exposure to Mobile Phones
This animal study examined maternal mobile phone exposure during different gestational windows in Wistar rats and assessed ovarian development and hormones in neonatal offspring. Compared with sham (phone off), exposed groups (standby and conversation/standby) were reported to have lower neonatal estrogen and progesterone and reduced primordial follicle/primary oocyte measures, with stronger effects after longer exposure. The study also reports increased primordial follicle apoptosis, particularly in the conversation/standby condition, and notes effects even with first-week gestational exposure.
Analyzing the Impact of Occupational Exposures on Male Fertility Indicators: A Machine Learning Approach
This occupational epidemiology study used machine learning to evaluate whether workplace exposures (including magnetic and electric fields, vibration, noise, and heat stress) predict male reproductive indicators in 80 workers. The models and explainable AI outputs highlighted magnetic and electric field exposures and age as key predictors linked to lower free testosterone. The authors also report a 10-year forecast identifying electric field exposure as the most important long-term risk factor.
A Mini-Review of the Potential Health Impacts of Indoor Radiation Exposure in Companion Animals
This mini-review discusses indoor radiation sources that may affect companion animals, including radon, radionuclides in feed, radiofrequency sources (phones, Wi-Fi, pet tracking devices), solar radiation, and extremely low frequency radiation. It reports that indoor radiation may negatively impact companion animal health and well-being. The authors conclude that preventive and precautionary measures are necessary to protect companion animals from indoor radiation exposure.
Effects of radiofrequency electromagnetic field exposure on cancer in laboratory animal studies, a systematic review
This systematic review evaluated RF EMF exposure and cancer outcomes in experimental animals, including chronic cancer bioassays and tumor-promotion designs. Across 52 included studies, the authors report high certainty of evidence for increased malignant heart schwannomas and gliomas in male rats, and moderate certainty for increased risks of several other tumor types. Many other organ systems showed no or minimal evidence of carcinogenic effects, and the authors note challenges in translating animal findings to human risk assessment due to exposure and mechanistic uncertainties.
The association of widely used electromagnetic waves exposure and pregnancy and birth outcomes in Yazd women: a cohort study
This cohort study of 1,666 women in Yazd City examined electromagnetic-wave exposure from commonly used devices during pregnancy and birth outcomes. Longer cell phone call duration during pregnancy was reported to be associated with higher risk of miscarriage, abnormal birth weight, and abnormal newborn height. Increased cordless phone use was also reported to be linked to abnormal birth weight, while other outcomes were assessed but not described as significantly associated in the abstract.
Effects of Mobile Electromagnetic Exposure on Brain Oscillations and Cortical Excitability: Scoping Review
This scoping review evaluates evidence on mobile phone electromagnetic exposure and its effects on brain oscillations and cortical excitability in healthy individuals. Across 78 EEG studies (and 2 TMS studies), the authors report that exposure may be linked to changes in neural activity, including increased amplitudes in several EEG bands and possible changes in cortical silent period. However, substantial methodological inconsistency across studies limits firm conclusions, and the review highlights limited evidence for 5G/mmWave exposures and argues for precaution and potential guideline revision.
Impact of expectancy on fatigue by exposure to the fifth generation of mobile communication signals
This randomized sham-controlled study in 21 healthy participants tested whether routine-level 5G RF-EMF exposure affects fatigue and EEG power, while manipulating expectancy via correct, false, or no information about exposure order. The study reports no change in EEG power with real versus sham exposure. However, self-reported fatigue varied with the conveyed information about being exposed, suggesting an expectancy/psychological priming effect on symptom reporting.
High Radiofrequency Radiation in the Surroundings of 10 Schools in Örebro, Sweden
This exposure assessment measured outdoor RF radiation from 4G/5G base stations near 10 schools in Örebro, Sweden (October 2024). The authors report maximum levels of 10,716–68,452 μW/m² and state these are far above EUROPAEM EMF guideline ranges; two locations also showed higher peak readings with a second meter. The paper frames these findings as indicating a significant health risk, particularly for children and sensitive groups, though no health outcomes were measured in this study.
Effects of 700MHz radiofrequency radiation (5G lower band) on the reproductive parameters of female Wistar rats
This animal study examined short- and long-term 700 MHz (lower-band 5G) radiofrequency exposure in female Wistar rats, comparing control, sham, and exposed groups. It reports no DNA damage and no change in estrous cycle length, but increased ovarian oxidative stress markers in exposed animals. Long-term exposure was associated with ovarian histopathological alterations, while estradiol and progesterone stayed within normal ranges and testosterone increased slightly but significantly.
Use of Electrical Household Appliances and Risk of All Types of Tumours: A Case-Control Study
This multi-hospital case-control study (n=316) examined associations between use of common household electrical appliances emitting ELF EMF and tumour risk. Most devices showed below-unity odds ratios, while computer screen and microwave oven use showed slightly increased odds with wide confidence intervals. Proximity to electricity transformer stations was associated with higher tumour odds, whereas proximity to powerlines was not.
Potential influence of geomagnetic activity on blood pressure statistical fluctuations at mid-magnetic latitudes
This six-year time series analysis used over 500,000 blood pressure measurements from two mid-magnetic latitude cities in China to examine associations with geomagnetic activity (Ap index). The study reports that blood pressure fluctuations correlate with geomagnetic activity and share similar periodic patterns, unlike air temperature and PM2.5. The authors conclude that high geomagnetic activity periods may increase risk for individuals with hypertension and note potential clinical and policy relevance.
