RF-EMF Exposure Assessment: Comparison of Measurements in Airports and Flights with and Without Wi-Fi Service

Research RF Safe Research Library Jan 1, 2025

This exposure assessment used personal exposimeters to measure RF-EMF levels in the 2.4 GHz and 5.85 GHz Wi-Fi bands in airport terminals and during four international flights, including flights with and without onboard Wi-Fi service. Reported mean exposures varied by route but were described as substantially below…

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

Research RF Safe Research Library Jan 1, 2025

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…

Radiofrequency electromagnetic fields reduce bumble bee visitation to flowers

Research RF Safe Research Library Jan 1, 2025

This blinded, two-year study examined whether RF-EMF exposure at 2.4 and 5.8 GHz affects pollinator visitation to Salvia and Lavandula. The authors report no significant effect on honey bee visitation rates. They report a significant reduction in bumble bee visits per observation period under RF-EMF exposure, which…

The influence of Wi-Fi on the mesonephros in the 9-day-old chicken embryo

Research RF Safe Research Library Jan 1, 2025

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…

Effects of 2.4 GHz radiofrequency electromagnetic field (RF-EMF) on glioblastoma cells (U -118 MG).

Research RF Safe Research Library Jan 1, 2023

This in vitro study exposed glioblastoma (U-118 MG) and human embryonic kidney (Hek-293) cells to 2.4 GHz RF-EMF for 24–72 hours, with or without a dielectric screen. The authors report a significant decrease in cell viability after exposure in both cell lines. The decrease was described as greater in glioblastoma…

Wi-fi related radiofrequency electromagnetic fields (RF-EMF): a pilot experimental study of personal exposure and risk perception.

Research RF Safe Research Library Jan 1, 2021

This pilot experimental study tested whether different types of information (basic text, precautionary information, or personal RF-EMF exposure measurements) affect perceptions of Wi-Fi (2.4 GHz) RF-EMF. Risk perception and exposure perception did not differ by the type of information provided, although receiving…

and Exposed to Wi-Fi Radiofrequency Electromagnetic Radiation Show Enhanced Growth and Lactic Acid Production.

Research RF Safe Research Library Jan 1, 2020

This in vitro experimental study exposed two Lactobacillus probiotic cultures to 2.4 GHz Wi‑Fi RF-EMF from a router for 15–60 minutes and compared them with sham-exposed controls. The authors report increased bacterial growth after 30–60 minutes of exposure, with no growth difference at 15 minutes. Lactic acid…

Combined Effects of Radiofrequency Electromagnetic Fields and X-Ray in Renal Tissue and Function.

Research RF Safe Research Library Jan 1, 2020

This animal experiment randomized 96 male Wistar rats to RF-EMF exposures (900/1800 MHz mobile phone or 2.4 GHz Wi-Fi), 8 Gy x-ray, or combinations, and assessed kidney function markers and histopathology. Creatinine was reported significantly higher and the BUN/Cr ratio significantly lower in the Wi-Fi group versus…

Assessment of function, histopathological changes, and oxidative stress in liver tissue due to ionizing and non-ionizing radiations.

Research RF Safe Research Library Jan 1, 2020

This animal study evaluated liver function, histopathology, and oxidative stress markers after exposure to RF-EMF (900/1800 MHz and 2.4 GHz), x-rays (10 cGy or 8 Gy), and combinations including RF-EMF pre-exposure. Some liver enzymes (AST, ALT, ALP) showed some association with irradiation, while…

Effect of Microwave Wi-Fi Radiation at Frequency of 2.4 GHz on Epileptic Behavior of Rats.

Research RF Safe Research Library Jan 1, 2018

This animal study exposed rats to 2.4 GHz Wi-Fi radiation for 2 hours at 30 cm from a commercial router and assessed PTZ-induced convulsive behavior. The Wi-Fi "on" PTZ group showed significant differences in seizure event counts and summed severity scores versus comparison groups, while several timing and duration…

Selenium supplementation ameliorates electromagnetic field-induced oxidative stress in the HEK293 cells.

Research RF Safe Research Library Jan 1, 2018

This in vitro study examined whether selenium supplementation modifies oxidative stress and apoptosis markers in HEK293 cells exposed to 2.4 GHz EMF. The authors report that EMF exposure increased lipid peroxidation (MDA) and apoptosis-related markers while decreasing antioxidant enzyme activities and bcl-2 versus…

Evaluation of the Effect of Radiofrequency Radiation Emitted From Wi-Fi Router and Mobile Phone Simulator on the Antibacterial Susceptibility of Pathogenic Bacteria and .

Research RF Safe Research Library Jan 1, 2017

This in vitro study assessed whether RF-EMF exposure from a GSM 900 MHz mobile phone simulator and a 2.4 GHz Wi-Fi router alters bacterial susceptibility to antibiotics. The authors report significant changes in inhibition zone diameters and bacterial growth rate after exposure. They also describe an exposure window…

Wireless Fidelity Electromagnetic Field Exposure Monitoring With Wearable Body Sensor Networks.

Research RF Safe Research Library Jan 1, 2016

This engineering paper presents an experimentally validated wearable personal exposimeter system for RF-EMF exposure monitoring, motivated by increasing wireless applications. It uses a distributed measurement approach and integrates inertial sensors to capture activity and posture during measurements. The system is…
