The study used 30 Wistar albino rats divided into two equal groups with tibial fractures fixed by K-wire. One group was exposed to 1800 MHz electromagnetic fields for 30 minutes daily, five days a week, while the other group was not exposed. Radiological, histological, and mechanical scores showed no significant differences between groups, and all scores were lower than controls. The researchers concluded that 1800 MHz electromagnetic radiation from cellular phones has no effect on bone fracture healing.

Researchers investigated the effects of 2.45 GHz microwave exposure on Escherichia coli cell membranes while maintaining the suspension at an average temperature of 37°C. No effect was detected with conventional heating or 200 W exposure, but membrane integrity was slightly altered at powers from 400 to 2000 W. Thermal characterization indicated the temperature reached was not high enough to explain the membrane changes, suggesting a power-dependent electromagnetic threshold effect. Exposures were discontinuous to keep the average temperature at 37°C, and effects were measured using flow cytometry with propidium iodide staining and intracellular protein release.

Researchers exposed mice to 2.45 GHz electromagnetic radiation (the same frequency used by Bluetooth devices) for up to 120 days to see if it would cause anxiety, obsessive-compulsive behaviors, or depression. The study found no behavioral changes in the mice at any time point, suggesting this level of EMF exposure did not affect their mental state or behavior patterns.
The animals were exposed to an access point (AP) from WIFI device (D-Link DWL-3200 AP with 802.11 g mode and WPA2 network protection) as previously described in Salah et al. et al. · 2013

Researchers exposed young male rats to Wi-Fi radiation (2.4 GHz) continuously for 20 weeks and found significant DNA damage in their reproductive organs. The Wi-Fi exposure also reduced the activity of key antioxidant enzymes that normally protect cells from damage. These findings suggest that prolonged Wi-Fi exposure during development could potentially harm reproductive health and fertility.

Kidney and testis samples were collected from decapitated rats during the fourth, fifth, and sixth weeks. In the fourth week, lipid peroxidation in kidney and testis and copper, zinc, GSH, GSH-Px, and TAS in kidney decreased, while iron in kidney and vitamin A and vitamin E in testis increased in exposed groups. In the fifth week, iron, vitamin A, and β-carotene in kidney increased, while GSH and TAS decreased in exposed groups. In the sixth week, iron concentrations in kidney and lipid peroxidation in kidney and testis increased, while copper, TAS, and GSH concentrations decreased in exposed groups.

The authors presented a framework that combines near-field and far-field radio frequency electromagnetic exposure sources to calculate average organ and whole-body specific absorption rates. Numerically derived SARs for whole-body and individual organs were combined with realistic exposure data collected using personal exposure meters during the Swiss Qualifex study. For users of GSM 900 or GSM 1800 phones, the 24-hour whole-body averaged exposure was dominated by the user's own mobile phone. If only UMTS phones were used, the average exposure level would be lower due to the lower average output power of UMTS phones. The data indicate the necessity of collecting band-selective exposure data in epidemiological studies of electromagnetic fields.

Twelve-week-old female mice were exposed to 2.45 GHz microwave radiation for 2 hours per day for 45 days to study effects on implantation and pregnancy. Implantation sites were significantly affected in the microwave-irradiated mice compared to controls. The researchers concluded that low-level microwave irradiation-induced oxidative stress suppresses implantation and may also lead to deformity of the embryo if pregnancy continues.

Researchers exposed female mice to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 2 hours daily over 45 days, using power levels far below current safety standards. The exposed mice showed significantly reduced pregnancy success, increased DNA damage in brain cells, and widespread oxidative stress throughout their bodies. This suggests that even low-level microwave radiation may interfere with reproductive health through cellular damage mechanisms.

Researchers exposed 100 Wistar rats to a 2.856 GHz pulsed microwave field at average power densities of 0, 5, 10, and 50 mW/cm² for 6 minutes. Rats exposed to 10 or 50 mW/cm² showed significant deficits in spatial learning and memory at 6 hours, 1 day, and 3 days after exposure. At the 5 mW/cm² level, exposed rats showed no difference compared with the sham group. The study suggested that impairment of LTP induction and damages of hippocampal structure, especially changes of synapses, might contribute to cognitive impairment after microwave exposure.

Researchers exposed rats to microwave radiation at cell phone levels and tested their memory abilities. Exposure at 10 and 50 mW/cm² significantly impaired spatial learning and memory while damaging brain cells in the hippocampus, revealing how wireless radiation can disrupt memory formation.

Researchers exposed rats to a 900 MHz electromagnetic field at a whole body average specific absorption rate of 1.08 W/kg for 1 hour per day for 3 weeks. Malondialdehyde and advanced oxidation protein product levels increased in rat brain tissue after electromagnetic field exposure. Nitric oxide levels in the brain showed no significant difference, but serum nitric oxide increased significantly after exposure, and garlic did not reduce that increase. The researchers also tested orally administered garlic powder at 500 mg/kg/day and found it had a protective effect against the oxidative stress seen in brain tissue.

Researchers exposed Japanese quail embryos in ovo to GSM 900 MHz radiofrequency radiation at 0.25 µW/cm2 for 158 to 360 hours on a discontinuous schedule. The exposure produced a significant persistent overproduction of superoxide and nitrogen oxide in embryo cells throughout the analysis period. Exposed embryo cells also showed significantly increased levels of TBARS and 8-oxo-dG alongside significantly decreased superoxide dismutase and catalase activities.

Researchers exposed developing quail embryos to extremely low-level cell phone radiation (900 MHz GSM) at power levels 4,000 times weaker than current safety limits. The exposure caused persistent overproduction of harmful free radicals and direct DNA damage in the developing embryos. The study demonstrates that even very weak radiofrequency radiation can trigger oxidative stress and genetic damage during critical developmental periods.

Researchers exposed rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) and tested their learning and memory abilities. The EMF-exposed rats showed impaired performance on tasks requiring natural exploration behavior and had altered brain chemistry, particularly in the hippocampus (a key memory center). Interestingly, adding iron overload to the brain didn't make the EMF effects worse, suggesting the radiation alone was sufficient to cause these cognitive changes.

Researchers exposed 32 trained Wistar rats to 916 MHz, 10w/m2 electromagnetic field for 6 hours a day, 5 days a week, over 10 weeks, and tested their spatial learning and memory in an eight-arm radial maze each weekend. During weeks 4–5, the exposed rats had longer completion times and higher error rates than the control group, but during weeks 1–3 and 6–9 the two groups were close to each other. The researchers concluded that the 916 MHz EMF influenced learning and memory in rats to some extent in a period during exposure, and that the rats can adapt to long-term EMF exposure.

Researchers exposed pregnant rats to 900-MHz mobile phone radiation for 6 hours daily throughout pregnancy and studied the brain development of their offspring. While the young rats showed no obvious behavioral problems, detailed electrical measurements revealed that specialized brain cells called Purkinje neurons (which help control movement and coordination) had altered electrical activity. This suggests that prenatal cell phone exposure can affect brain development at the cellular level, even when outward behavior appears normal.

Researchers exposed rats to extremely low-level 900 MHz microwave radiation (similar to cell phone frequencies) for 2 hours daily over 30 days. The exposed rats showed significant memory and learning problems, plus increased oxidative stress (cellular damage) in their blood. This matters because the radiation level was about 1,000 times lower than current safety limits, yet still caused measurable brain and cellular effects.

Researchers exposed rats to extremely low-level 900 MHz microwave radiation (similar to cell phone frequencies) for 2 hours daily over 30 days. The exposed rats showed significant cognitive impairment and increased oxidative stress (cellular damage from harmful molecules called free radicals) compared to unexposed control rats. This suggests that even very weak microwave radiation can affect brain function and cause cellular damage.

Researchers exposed male and female Wistar rats to a 2450 MHz Wi-Fi signal for 1 hour per day, 6 days per week. Exposure lasted 3 weeks for males and 2 weeks for females before mating, then continued for 3 more weeks during gestation. No deleterious effects on reproductive organs or fertility were observed, and no macroscopic abnormalities were found in fetuses even at 4 W/kg.
