This National Toxicology Program technical report describes 900 MHz whole-body RFR exposures (GSM and CDMA) in male and female Sprague Dawley rats from in utero through up to 2 years. The report concludes clear evidence of carcinogenic activity in males for both modulations based on malignant schwannoma of the heart,…

This animal study examined whether acute GSM-1800 MHz exposure affects the auditory cortex during experimentally induced neuroinflammation. In LPS-treated rats, a single 2-hour head-only exposure (average SAR 1.55 W/kg in auditory cortex) was associated with altered microglial morphology and reduced neuronal activity…

This animal study used developing quail embryos to assess oxidative and mutagenic effects of low-intensity GSM 1800 MHz radiation from a commercial smartphone. The authors report statistically significant increases in oxidative stress markers, DNA integrity damage, and oxidative DNA damage (8-oxo-dG) in exposed…

This NTP technical report describes long-term rat studies exposing animals to 900 MHz GSM and CDMA-modulated radiofrequency radiation at whole-body SAR levels of 0, 1.5, 3, and 6 W/kg, including exposure beginning before birth. The abstract reports NTP concluded there was "clear evidence" for malignant schwannoma of…

This animal study exposed male Sprague-Dawley rats to 900 MHz GSM mobile phone RF radiation for 4 hours and assessed ERα promoter methylation in colon tissue. The authors report altered ERα methylation patterns versus controls after RF exposure. They also report no radioadaptive response in ERα methylation following…

This animal study examined whether long-term 900 MHz GSM-like microwave exposure affects experimentally induced cutaneous candidiasis in BALB/c mice. Exposed mice reportedly had delayed wound healing and higher Candida loads in skin lesions compared with unexposed mice. Following systemic Candida challenge, exposed…

This animal study examined iron distribution in rabbit cerebellum after exposure to RF electromagnetic fields, using light and scanning electron microscopy with energy-dispersive microanalysis. The authors report dystrophic changes in Purkinje cells in irradiated groups and deposits containing multiple elements…

This cross-sectional questionnaire study examined stress and mobile phone use in GSM network employees. Stress measures differed across groups defined by phone use duration and conversation length. Speaking on a mobile phone for more than 60 minutes/day was associated with a higher reported risk of headaches even…

This in vitro study evaluated adult murine neural stem cells exposed to GSM 900-MHz radiofrequency emissions from a mobile phone across different exposure durations. The authors report significant decreases in neurosphere number/size and neuronal differentiation with increasing exposure duration. They report no…

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…

This rat study examined whether pulse-modulated 900 MHz and 1800 MHz RF exposure affects blood-brain barrier permeability using Evans blue dye. The abstract reports increased permeability in male rats at both frequencies (stronger at 1800 MHz) and in female rats at 900 MHz but not at 1800 MHz. The authors suggest…

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…

This study tested whether radiofrequency emissions from a ringing GSM mobile phone affect home blood glucose monitor readings. Among 45 female nondiabetic students, the group measured in the presence vs absence of a ringing phone showed larger changes between two readings than a repeat-measurement control group…

This experimental study exposed adult male Wistar rats to 900 MHz GSM-band cell phone-related waves for 2 or 3 weeks and assessed sperm parameters and total antioxidant capacity. All exposure groups showed significantly reduced sperm viability, motility, and total antioxidant capacity compared with controls.…

This in vitro study tested whether 900 MHz GSM mobile phone radiation affects ferritin measurements in human serum wells. Exposed wells (30 minutes, speech-mode phone) showed a statistically significant decrease in ferritin compared with unexposed controls. The authors propose RF exposure may influence…

This animal study assessed DNA damage in rat brain, liver, and kidney cells after repeated whole-body exposure to 915 MHz GSM-modulated RF radiation (SAR 0.6 W/kg) using the comet assay. Tail length was slightly increased in brain cells and differed more notably in liver and kidney samples versus sham controls, while…
