Visualizing radiofrequency electromagnetic field exposure through Voronoi-based maps

RF Safe Research Library Jan 1, 2025 NEUTRAL MEDIUM

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.

Thermal and SAR-Based Limits for Human Skin Exposed to Terahertz Radiation

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This conference paper uses COMSOL Multiphysics simulations to evaluate thermal and SAR-based exposure limits for modeled human skin exposed to terahertz radiation (0.1–5 THz). The authors report negligible temperature increases at power densities consistent with keeping SAR below 1.6 W/kg, but note that higher power densities can yield minimal heating while producing SAR values above recognized safety thresholds. They conclude that existing sub-THz standards are not directly transferable to the full THz band and call for updated guidelines, especially for prolonged exposure.

Prolonged 3.5 GHz and 24 GHz RF-EMF Exposure Alters Testicular Immune Balance, Apoptotic Gene Expression, and Sperm Function in Rats

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This rat study examined 60-day RF-EMF exposure at 3.5 GHz and 24 GHz for 1 or 7 hours per day and assessed testicular cytokines, apoptosis-related gene expression, and sperm quality. The authors report changes consistent with altered immune signaling and pro-apoptotic pathways, alongside reduced sperm parameters (frequency- and duration-dependent). The conclusion frames these findings as an EMF safety concern and suggests longer daily exposure worsened negative effects.

The effect of Wi-Fi on elastic and collagen fibres in the blood vessel wall of the chorioallantoic membrane

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This animal experimental study exposed chicken embryos (CAM) continuously to 2.4 GHz Wi-Fi at an average power density of 300 μW/m2 for 9 or 14 embryonic days. H&E staining reportedly showed no significant structural differences in large vessel walls versus controls. However, special staining reported decreased optical density of elastic fibers at both time points and changes in collagen fiber optical density (increase at day 9, decrease at day 14). The authors conclude Wi-Fi exposure can alter fibrous vessel wall components and suggest potential relevance to cardiovascular disorders.

Investigating the Effects of Occupational Noise and Extremely Low-Frequency Electromagnetic Field Exposure on Oxidative Response in Power Plant Workers

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This occupational study compared oxidative stress biomarkers across four groups: control, noise-only, ELF-EMF-only, and combined noise plus ELF-EMF exposure in power plant workers. The combined exposure group showed higher lipid peroxidation (MDA) and lower antioxidant-related measures (GSH and TAC) versus controls, while SOD activity was reduced in the noise-only and combined groups. The authors interpret these findings as evidence linking concurrent noise and ELF-EMF exposure with increased oxidative stress and call for further research and occupational safety guidance.

A Cohort Study on Alzheimer's Disease in Relation to Residential Magnetic Fields From Indoor Transformer Stations

RF Safe Research Library Jan 1, 2025 REASSURANCE MEDIUM

This cohort study evaluated Alzheimer's disease incidence in relation to residential extremely low frequency magnetic fields from indoor transformer stations, using apartment location as an exposure proxy. No significant association was observed between living next to transformer stations and Alzheimer's disease risk (HR 1.02, 95% CI 0.85–1.22). Duration of residence did not materially change risk, and a younger-start subgroup showed a non-significant elevation. The authors note the results did not replicate previously reported positive associations from other residential or occupational studies.

Effect of Increased Ionizing Radiation and Near-Null Magnetic Field on Electrical Signals of Plants

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This experimental study examined how increased β ionizing radiation (31.3 μGy/h) and hypomagnetic conditions (0–1.5 μT) affect plant electrical signaling responses to stimuli. It reports enhanced electrical signals under increased ionizing radiation and weakened signals under near-null magnetic field conditions. The authors suggest these effects may be mediated by changes in reactive oxygen species involved in stress signaling.

The WHO-commissioned systematic reviews on health effects of radiofrequency radiation provide no assurance of safety

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This paper evaluates and critiques 12 WHO-commissioned systematic reviews and meta-analyses on RF-EMF health effects across outcomes including cancer and reproductive endpoints. It argues that serious methodological flaws and limitations in the WHO reviews prevent them from providing assurance of safety for cell phones and other wireless devices. The authors highlight reported evidence in the animal cancer review (high certainty for heart schwannomas; moderate certainty for brain gliomas) and describe dose-related adverse effects on male fertility and reproductive outcomes, including at exposure levels below current ICNIRP thresholds.

Review of the evidence on the influence of Wi-Fi 2.4 GHz radiation on oxidative stress and its possible relationship with Alzheimer's disease

RF Safe Research Library Jan 1, 2025 CONCERN UNKNOWN

The review states there is no scientific consensus on whether Wi‑Fi (2.4/5 GHz) contributes to Alzheimer's disease through oxidative stress, and that existing results are mixed and inconclusive. It discusses an indirect analysis linking oxidative-stress-responsive genes after 2.4 GHz exposure with genes associated with Alzheimer's disease. The authors suggest chronic exposure could affect regulation of neurodegeneration-related genes (e.g., GSK3B, APOE), while emphasizing that a direct relationship has not been demonstrated and more research is needed.

Microwave and RF Exposure-Induced Molecular and Genetic Alterations

RF Safe Research Library Jan 1, 2025 CONCERN UNKNOWN

This review discusses recent studies on microwave and RF exposure and their reported impacts on molecular and cytogenetic materials. It states there is growing evidence that RF exposure can induce DNA damage at levels considered safe by current standards, and cites newly reported genetic alterations in rat cancers after lifetime low-level RF exposure. The article concludes that these findings challenge existing exposure guidelines and support reconsideration of regulatory limits.

Experience of Polish Physicians on Electromagnetic Hypersensitivity

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This cross-sectional questionnaire study surveyed 355 Polish physicians about EMF health effects and electromagnetic hypersensitivity (EHS). Physicians reported limited knowledge and low familiarity with WHO guidance for managing people who believe they are hypersensitive to EMF, though most were willing to learn more. Many physicians reported encountering patients attributing symptoms to EMF, which the authors frame as highlighting a need for improved physician education and reliable public information.

Causal relationship between the duration of mobile phone use and risk of stroke: A Mendelian randomization study

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This Mendelian randomization study assessed whether duration of mobile phone use is causally related to stroke outcomes using GWAS-derived SNP instruments. The inverse-variance weighted analysis reported a significant increased risk for large artery atherosclerosis (LAAS) with longer mobile phone use duration, while other stroke outcomes showed no significant associations. Sensitivity analyses (including MR-Egger and heterogeneity/asymmetry tests) were reported as suggesting the LAAS finding was robust.

Differential metabolic responses of mouse Leydig and spermatogonia cells to radiofrequency electromagnetic field exposure

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This in vitro study used LC-MS metabolomics to assess how continuous versus intermittent RF-EMF irradiation affects mouse Leydig (TM3) and spermatogonia (GC-1) cells. The authors report stronger metabolic disturbances in TM3 cells under continuous exposure, including changes in amino acid and glutathione-related pathways, while intermittent exposure mainly affected fatty acyl and purine-related metabolism. GC-1 cells were reported to be less sensitive, and ADP changes were proposed as a potential metabolic signature. The authors interpret these metabolic disturbances as suggesting potential reproductive health risks.

Radiofrequency regulates the BET-mediated pathways in radial glia differentiation in human cortical development

RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This in vitro study reports that radiofrequency (RF) exposure in the 800–2,400 MHz range modulates differentiation pathways in human cortical organoids derived from embryonic stem cells. RF exposure is described as maintaining radial glia stem cell identity and delaying differentiation, alongside induction of endogenous retrovirus expression and increased expression of ASD-associated genes and retroelements. The abstract attributes these effects to dysregulation of BET proteins and reports that BET inhibition rescues the RF-associated developmental defects.

Investigation of fetal exposure to electromagnetic waves between 2.45 and 5 GHz during pregnancy

RF Safe Research Library Jan 1, 2025 NEUTRAL MEDIUM

This dosimetry study simulated fetal RF-EMF exposure between 2.45 and 5 GHz during the second trimester, estimating SAR10g in fetal brain and lungs. The presence of a belly-button piercing increased SAR, with maxima reported at 2.45 GHz (16 mW/kg in lungs; 14 mW/kg in brain). Despite these increases, all SAR values were reported to remain below IEEE and ICNIRP limits, while the authors note a precautionary implication regarding metal objects during pregnancy.
