RF Safe comments on a 2025 PNAS Nexus study (Jyoti et al., 2025) reporting no detectable changes in gene expression or methylation in 5G millimeter-wave–exposed human skin cells. The post argues that this “null” result does not indicate biological inertness, but instead supports the site’s proposed “dual-pillar”…

RF Safe argues that findings it describes as “high-certainty” from WHO-commissioned systematic reviews show RF-EMF causes malignant heart Schwannomas and brain gliomas in rodents and reduces male fertility. The post proposes a unifying non-thermal mechanism—the “S4-mitochondria axis”—suggesting RF-EMF interacts with…

RF Safe argues that radiofrequency radiation (especially pulsed or modulated signals with low-frequency components) can alter local membrane potentials at nanometer scales where voltage-gated ion channel S4 sensors operate. It claims these shifts could change ion channel gating in immune cells, altering calcium and…

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…

This paper presents a bibliometric analysis of Web of Science literature (2012–2025) on potential health effects related to 5G antennas. 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…

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 (

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…

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…

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…

This in vitro study examined effects of moderate static magnetic field exposure on sympathetic neuron-like PC12 cells. The authors report a significant reduction in voltage-gated potassium (Kv) channel current density after 18 hours of exposure, with the reduction persisting after the field was removed. RNA…

This laboratory study exposed cultured Phaeocystis globosa to extremely low-frequency electromagnetic fields (ELF-EMF) at 0, 0.2, and 1 mT for 24 hours. The authors report increased cell density, photosynthesis, and chlorophyll a under ELF-EMF, alongside decreased protein and carbohydrate accumulation. Metabolomic…

This animal study examined repeated pulsed-modulated RF exposure (1–4 GHz; total pulse power density 300 μW/cm2) in male and female Wistar rats and assessed behavior using the open field test. The abstract reports stress reactions and long-term memory impairment in some rats, with females described as more sensitive…

This animal experiment examined hematopoietic and immune-related indicators in mice after repeated exposure to low-intensity microwave radiation. Exposure involved monochromatic pulsed fields in the 2.27–2.78 GHz range with average power flux density of 60 μW/cm² and doses of 0.086–0.86 J/g. The authors report…
