Showing results for: GSM 900 MHz

Effects of radiofrequency electromagnetic fields on cognitive function in elderly subjects (60+ years)-Results of an experimental randomized sham controlled double-blind cross-over study in women and in men.

Research RF Safe Research Library Jan 1, 2025

This double-blind randomized sham-controlled cross-over study tested short-term RF-EMF exposure effects on cognitive performance in 60 healthy adults aged 60–80 years. Participants completed attentional tasks during exposure to GSM 900 MHz, TETRA 385 MHz, or sham across nine sessions. Two of 16 outcomes showed…

Effects of radiofrequency electromagnetic radiation (RF-EMF) on honey bee queen development and mating success.

Research RF Safe Research Library Jan 1, 2019

This animal study exposed honey bee queen larvae to RF-EMF from a common mobile phone (GSM 900 MHz) across all pre-adult developmental stages for 14 days. The authors report a significantly reduced queen hatching ratio, while mating success was not affected. For queens that successfully mated, subsequent colony…

Effect of acute exposure to radiofrequency electromagnetic fields emitted by a mobile phone (GSM 900 MHz) on electrodermal responsiveness in healthy human.

Research RF Safe Research Library Jan 1, 2018

This study examined whether acute GSM 900 MHz mobile phone exposure affects electrodermal activity responses to auditory stimuli in 28 young volunteers. The authors report no exposure-related changes in SCR latency, amplitude, integral, or number of responses. Session differences in skin conductance/tonic…

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…

[The activity of prooxidant-antioxidant system in loach embryos under the action of microwave radiation].

Research RF Safe Research Library Jan 1, 2014

This animal study examined oxidative stress and antioxidant defenses in loach embryos exposed to GSM 900 MHz microwave radiation (SAR 1.1 W/kg) for 1–20 minutes during early embryogenesis. The authors report significant changes in lipid peroxidation products and altered antioxidant enzyme activities. They conclude…

Investigating short-term exposure to electromagnetic fields on reproductive capacity of invertebrates in the field situation.

Research RF Safe Research Library Jan 1, 2014

This field experiment examined short-term (48-hour) exposure to RF EMF from a GSM 900 MHz mobile phone base station on reproductive endpoints in four invertebrate species. The study reports no significant effects of exposure metrics on fecundity or number of offspring, and notes that distance was not a suitable proxy…
