Researchers prepared class V cavities in 20 extracted human premolars and randomly divided them into two groups of 10. The experimental group was exposed to 2.4 GHz Wi-Fi radiation for 20 minutes at a distance of 30 cm while the router communicated with a laptop 20 meters away. Mercury concentration in artificial saliva was significantly higher in the exposed group (0.056 ± .025 mg/L) than in the control group (0.026 ± .008 mg/L) (P =0.009).

Evidence of cellular stress and caspase-3 resulting from a combined two-frequency signal in the cerebrum and cerebellum of sprague-dawley rats.

López-Furelos A et al. · 2016

Forty rats were divided into four groups of ten. Twenty-four hours after exposure, HSP 90 and HSP 70 levels differed between cerebral hemispheres at high SAR, while caspase-3 did not. In cerebellar hemispheres, single RF exposure at high SAR altered HSP 90, HSP 70, and caspase-3 compared with controls. The combined signals did not produce additive effects on absorbed energy or biological outcomes.

The apoptotic effect and the plausible mechanism of microwave radiation on rat myocardial cells.

Zhu W, Cui Y, Feng X, Li Y, Zhang W, Xu J, Wang H, Lv S. · 2016

Rats were treated with 2450 MHz microwave radiation at 50, 100, 150, or 200 mW/cm(2) for 6 min. Microwave treatment increased malondialdehyde content while decreasing antioxidative stress enzymes, activities of enzyme complexes I-IV, and ATP in myocardial tissues. Irradiated myocardial cells exhibited structural damage and underwent apoptosis. The researchers suggested that microwave irradiation could induce myocardial cell apoptosis by interfering with oxidative stress and cardiac energy metabolism.

Effect of Low Level Subchronic Microwave Radiation on Rat Brain

Deshmukh PS et al. · 2016

Researchers exposed male Fischer rats to microwave radiation for 90 days at 900, 1800, and 2450 MHz to investigate effects on cognitive function, heat shock protein 70 (HSP70) levels, and DNA damage in the brain. Cognitive function was tested using the elevated plus maze and Morris water maze, HSP70 levels were measured by ELISA, and DNA damage was assessed using alkaline comet assay. The results suggest that low-level microwave exposure at these frequencies may lead to hazardous effects on the brain.

Does prolonged radiofrequency radiation emitted from Wi-Fi devices induce DNA damage in various tissues of rats?

Akdag MZ et al. · 2016

The study used 16 adult male Wistar-Albino rats, with 8 exposed to 2.4 GHz radiation for over a year and 8 sham-exposed. DNA damage in brain, liver, kidney, skin, and testicular tissues was measured using the comet assay as percentage tail DNA. Percentage tail DNA increased in brain, kidney, liver, and skin of exposed rats but the increases were not statistically significant. In contrast, DNA damage in testicular tissue increased significantly (p < 0.01). The authors concluded that long-term 2.4 GHz Wi-Fi exposure does not cause DNA damage in the examined organs except testes, which appear more sensitive.

Low intensity microwave radiation induced oxidative stress, inflammatory response and DNA damage in rat brain

Megha et al. · 2015

Researchers exposed 24 male Fischer 344 rats to microwave radiation at 900, 1800, and 2450 MHz with specific absorption rates of 0.59, 0.58, and 0.66 mW/kg for 60 days (2 hours per day, 5 days per week). Exposure increased oxidative stress markers malondialdehyde, protein carbonyl, and catalase, while decreasing reduced glutathione and superoxide dismutase. Pro-inflammatory cytokines IL-2, IL-6, TNF-α, and IFN-γ were significantly elevated in exposed rats. Significant DNA damage was observed in the microwave exposed groups compared to sham.

Low intensity microwave radiation induced oxidative stress, inflammatory response and DNA damage in rat brain

Unknown authors · 2015

Researchers exposed rats to low-intensity microwave radiation at cell phone frequencies (900, 1800, and 2450 MHz) for 60 days and found significant brain damage. The study revealed increased oxidative stress, inflammation, and DNA damage in the hippocampus, with effects becoming more severe at higher frequencies. This suggests that even very low power microwave exposure can harm brain tissue through multiple biological pathways.

At distances of 0, 1, and 5 cm, exposed cells showed higher reactive oxygen species, calcium concentrations, apoptosis, and caspase activity compared to controls, while cell viability increased with distance. No statistically significant differences were observed between control cells and those exposed at 20 or 25 cm.

Investigation of the effects of distance from sources on apoptosis, oxidative stress and cytosolic calcium accumulation via TRPV1 channels induced by mobile phones and Wi-Fi in breast cancer cells

Çiğ B, Nazıroğlu M · 2015

Researchers exposed breast cancer cells to radiation from mobile phones (900 MHz, 1800 MHz) and Wi-Fi (2450 MHz) at various distances for one hour. They found that EMF exposure within 10 cm triggered harmful cellular effects including oxidative stress, calcium overload, and programmed cell death, while distances beyond 10 cm showed no significant effects. This suggests maintaining distance from wireless devices may reduce biological harm.

Deshmukh PS et al. · 2015

Researchers exposed male Fischer rats to microwave radiation for 180 days at 3 different frequencies, namely, 900, 1800 MHz, and 2450 MHz. The study investigated effects on cognitive function, heat shock protein 70 (HSP70), and DNA damage in rat brain. The results showed declined cognitive function, elevated HSP70 level, and DNA damage in the brains of microwave-exposed animals. The researchers concluded that chronic low-intensity microwave exposure in the frequency range of 900 to 2450 MHz may cause hazardous effects on the brain.

Impact of 2.45 GHz microwave radiation on the testicular inflammatory pathway biomarkers in young rats: The role of gallic acid.

Saygin M, Asci H, Ozmen O, Cankara FN, Dincoglu D, Ilhan I. · 2015

Six-week-old male Sprague Dawley rats were divided into four groups, including a sham group, an EMR-only group exposed to 2.45 GHz radiation for 3 hours per day for 30 days, an EMR plus gallic acid group, and a gallic acid-only group. EMR exposure increased malondialdehyde and total oxidant status levels, decreased total antioxidant status, and raised prostaglandin E2 and calcitonin gene-related peptide staining in testicular tubules. Gallic acid treatment lowered total oxidant status and oxidative stress index and raised total antioxidant status. It also reduced prostaglandin E2 and calcitonin gene-related peptide staining and increased testosterone and VEGF levels relative to the EMR-only group.

Impact of 2.45 GHz microwave radiation on the testicular inflammatory pathway biomarkers in young rats: The role of gallic acid.

Saygin M, Asci H, Ozmen O, Cankara FN, Dincoglu D, Ilhan I · 2015

Researchers exposed young male rats to 2.45 GHz microwave radiation (the same frequency as WiFi and Bluetooth) for 3 hours daily over 30 days and found significant damage to testicular tissue and sperm production. The radiation increased oxidative stress markers and inflammatory proteins while reducing sperm counts in the testes. However, when rats were given gallic acid (an antioxidant found in tea and berries), it largely prevented these reproductive damages.

Oxidative stress of brain and liver is increased by Wi-Fi (2.45GHz) exposure of rats during pregnancy and the development of newborns

Unknown authors · 2015

Researchers exposed pregnant rats and their newborns to 2.45 GHz electromagnetic radiation for 1 h per day, 5 days a week, from pregnancy to 3 weeks of age. Lipid peroxidation increased in both brain and liver, while glutathione peroxidase activity and vitamins A, E, and β-carotene decreased in both organs. Glutathione and vitamin C concentrations fell in the brain but not in the liver, and the brain appeared more sensitive to oxidative injury than the liver.

The Role of the Location of Personal Exposimeters on the Human Body in Their Use for Assessing Exposure to the Electromagnetic Field in the Radiofrequency Range 98-2450 MHz and Compliance Analysis: Evaluation by Virtual Measurements

Gryz K et al · 2015

Researchers modeled personal exposimeters measuring electric fields from 98–2450 MHz using a human body model and finite integration technique software. Calculations with 256 exposure scenarios showed the human body causes measurement errors from −96% to +133% compared to unperturbed fields. Placing a single exposimeter on the waist to the back side of the human body or on the front of the chest reduces the range of exposure assessment uncertainty across various conditions. Uncertainty using a single exposimeter remains significantly higher than spot measurements of unperturbed fields.
