Researchers exposed mouse sperm-producing cells to cell phone radiation (1950 MHz) at 3 W/kg for 24 hours, both alone and combined with X-ray radiation. While the RF radiation alone caused no harm, when combined with X-rays it significantly increased cell death and reduced cell growth compared to X-rays alone. This suggests that cell phone radiation may make cells more vulnerable to other forms of radiation damage.

Researchers exposed young male rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during their adolescent development period. The exposed rats showed increased oxidative stress in their thymus (a key immune system organ) and tissue damage including bleeding into the tissue. This suggests that RF radiation during development may harm the immune system by creating damaging free radicals.

Italian researchers exposed blood samples from 16 healthy volunteers to smartphone radiation (900 MHz) for 30 minutes and found significant changes in platelet function. The exposed blood showed altered clotting behavior and increased platelet size compared to unexposed samples. This suggests that smartphone radiation can directly affect blood components involved in clotting and wound healing.

Researchers exposed 30 emergency physicians to cell phone radiation (900-1800 MHz) for 15 minutes and tested their attention and concentration using standardized cognitive tests. Surprisingly, doctors exposed to the radiation actually performed better on selective attention tasks compared to those holding phones that were turned off. The study suggests short-term cell phone radiation exposure may temporarily enhance certain cognitive functions rather than impair them.

Scientists exposed mice to cell phone radiation (1.8 GHz) and found it improved memory performance at high exposure levels. The radiation physically changed brain cells and their electrical activity in memory regions, demonstrating that radiofrequency energy can directly alter how the brain functions.
Bodera P et al. · 2017
Researchers exposed rats to cell phone radiation (1800 MHz) to study brain effects. They found no changes in healthy rats, but radiation combined with existing inflammation affected brain receptors involved in learning and memory, suggesting inflamed brains may be more vulnerable.

Researchers exposed onion roots to 2100 MHz cell phone radiation for 1-4 hours and measured cellular damage markers. The radiation triggered oxidative stress, causing harmful molecules called reactive oxygen species to build up while forcing the plant cells to work harder to defend themselves. This demonstrates that radiofrequency radiation can disrupt normal cellular function even in plant tissue.

Researchers exposed 50 rats to 915 MHz radiofrequency radiation (similar to microwave ovens) at different power levels for 4 hours daily over one week, then tested whether this 'primed' their livers to better handle radiation damage. They found that low-power RF exposure increased protective antioxidant enzymes in the liver, creating an 'adaptive response' that helped protect against subsequent high-dose gamma radiation damage.

Researchers exposed female mice to 1800 MHz mobile phone radiation (the frequency used by GSM networks) and found it significantly damaged their reproductive systems. The radiation increased harmful stress molecules in the brain, ovaries, and uterus while reducing fertility hormones and the number of healthy egg follicles. This suggests that mobile phone radiation may impair female fertility through cellular stress pathways.

Researchers exposed mice to 900 MHz cell phone radiation for 6 hours daily over several weeks, then infected them with a common fungal pathogen (Candida) to test their immune response. The radiation-exposed mice showed delayed wound healing, higher infection levels in their skin, and increased susceptibility to life-threatening systemic infections. This suggests that chronic exposure to cell phone frequencies may weaken the immune system's ability to fight off infections.

Iranian researchers exposed rats to 915 MHz radiofrequency radiation (similar to microwave ovens) for 4 hours daily over one week, then tested whether this 'primed' their liver cells to better handle a subsequent dose of gamma radiation. They found that low-power RF exposure increased antioxidant enzymes like glutathione, which helped protect liver tissue from oxidative damage when the rats were later exposed to harmful gamma radiation.
Danese E et al. · 2017
Italian researchers exposed blood samples from 14 healthy volunteers to 900 MHz radiofrequency radiation from a commercial mobile phone for 30 minutes, then examined the cells for DNA damage markers called gamma-H2AX foci. They found no significant increase in DNA breaks or genetic damage compared to unexposed blood samples. This suggests that short-term mobile phone radiation exposure at typical frequencies may not cause immediate detectable DNA damage in human immune cells.

Researchers exposed brain cells to cell phone radiation (1950 MHz) for 2 hours daily over 3 days to see if it affected amyloid-beta processing, which is linked to Alzheimer's disease. They found no significant changes in the proteins that create these brain plaques. However, the researchers noted that longer-term exposure might produce different results than their short 3-day study.

Chinese researchers exposed adolescent mice to cell phone frequency radiation (1.8 GHz) for four weeks and tested their behavior and brain function. While the mice showed no changes in depression, memory, or brain structure, they did display increased anxiety-like behavior and had lower levels of key brain chemicals that regulate mood and brain activity. This suggests that radiofrequency exposure during adolescence may specifically affect anxiety responses in the developing brain.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency electromagnetic field exposure around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. Boys living in areas with higher RF exposure (though still below safety guidelines) showed some concerning patterns including lower verbal skills and higher rates of anxiety-related problems. While the study found mostly no effects, the few significant associations raise questions about environmental RF exposure during critical brain development years.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency radiation around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. While most measures showed no effects, boys living in areas with higher RF exposure (though still below safety guidelines) had lower verbal skills and higher rates of anxiety-related behaviors compared to those in lower exposure areas. The researchers cautioned that study limitations prevent drawing definitive conclusions.

Researchers exposed pregnant rats to 900 MHz cell phone radiation for 6 hours daily and then tested their offspring's brain function. The exposed offspring showed reduced brain cell activity in the hippocampus (the brain's memory center) and performed worse on learning and memory tests. This suggests that cell phone exposure during pregnancy may impair brain development in offspring.
Erdem Koç G et al. · 2016
Pregnant rats exposed to cell phone radiation (900 MHz) for one hour daily had offspring with fewer brain cells in the hippocampus, the memory center. Melatonin and omega-3 supplements during pregnancy prevented this brain damage, suggesting potential protective strategies for human prenatal development.
Erdem Koç G et al. · 2016
Pregnant rats exposed to cell phone-level radiation (900 MHz) for one hour daily produced offspring with fewer brain cells in the hippocampus, the memory center. However, melatonin and omega-3 supplements during pregnancy prevented this brain damage in the developing babies.
Erdem Koç G et al. · 2016
Turkish researchers exposed pregnant rats to cell phone radiation (900 MHz) for one hour daily throughout pregnancy, then examined brain development in their male offspring. They found that prenatal radiation exposure significantly reduced the number of pyramidal neurons in the hippocampus (a brain region critical for memory and learning). However, when pregnant rats received protective supplements like melatonin or omega-3 fatty acids alongside the radiation exposure, their offspring's brain development remained normal.

Australian researchers measured radiofrequency electromagnetic field (RF-EMF) exposure levels in kindergarten children from cell towers, Wi-Fi, and other wireless sources. They found that environmental exposure levels in kindergarten settings were significantly higher than the personal exposure levels children experienced, with cell tower signals being the dominant source of exposure at levels up to 179 mV/m.

Researchers exposed male mice to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for 4-8 hours daily for 35 days to study effects on sperm production. The radiation caused DNA damage in sperm-producing cells and disrupted the normal development process, resulting in significantly reduced sperm counts. While some recovery occurred after radiation exposure ended, the study demonstrates that RF radiation can impair male fertility through cellular damage.
Odacı E et al. · 2016
Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for one hour daily during pregnancy, then examined the reproductive health of their male offspring at 60 days old. The exposed animals showed significantly reduced sperm quality, including lower sperm motility and vitality, along with increased DNA damage and cell death in their testes. This study suggests that EMF exposure during critical developmental periods may have lasting effects on male fertility.

Researchers exposed pregnant rats to cell phone-frequency radiation (900 MHz) for one hour daily during late pregnancy and examined their female offspring's ovaries at 34 days old. The exposed offspring had significantly fewer healthy egg follicles and more damaged, dying follicles compared to unexposed controls. This suggests that EMF exposure during pregnancy may harm the developing reproductive system of female offspring.
Son Y et al. · 2016
Researchers exposed mice genetically modified to develop Alzheimer's-like symptoms to cell phone radiation (1950 MHz) for 3 months to see if it would worsen their memory problems. The radiation exposure at 5 W/kg (about 5 times higher than typical phone use) did not make the mice's memory worse or increase the brain plaques associated with Alzheimer's disease. This suggests that cell phone radiation may not accelerate Alzheimer's progression, at least in this animal model.
