De Amicis A et al. · 2015
Researchers exposed human fetal cells to terahertz (THz) radiation at 0.1-0.15 THz frequencies and found chromosome damage without DNA breaks. The study revealed increased micronuclei formation and abnormal cell structure changes, suggesting THz radiation can cause chromosomes to separate incorrectly during cell division.

Researchers exposed rats to Wi-Fi radiation (2.4 GHz) 24 hours daily for one full year and found significant changes in brain microRNA expression. Two specific microRNAs decreased by over 3 times compared to unexposed rats. The researchers concluded this could contribute to neurodegenerative diseases.
Megha et al. · 2015
Researchers exposed rats to low-level microwave radiation at cell phone frequencies (900, 1800, and 2450 MHz) for 60 days and found significant brain damage. The radiation caused oxidative stress, inflammation, and DNA damage in brain tissue, with effects becoming more severe at higher frequencies.
Malkemper EP et al. · 2015
Researchers tested whether wood mice can sense magnetic fields by observing where they built nests in circular arenas. They found that mice normally oriented their nests north-south using Earth's magnetic field, but when exposed to weak radio frequency fields (0.9-5 MHz), the mice switched to building nests east-west instead. This demonstrates that low-level RF exposure can disrupt an animal's natural magnetic navigation system.

Researchers exposed diabetic rats to cell phone radiation (2100 MHz) to see if it caused genetic damage in bladder cells by looking for micronuclei - small fragments of broken DNA that indicate cellular damage. They found no increase in genetic damage in either healthy or diabetic rats exposed to the radiation compared to unexposed animals. The study suggests that this level of RF radiation may not cause DNA damage in bladder cells, even in animals with diabetes who might be more vulnerable.
Percherancier Y et al. · 2015
Researchers exposed mouse cells to 50 Hz magnetic fields for 24 hours to study whether these fields affect gap junctions (tiny channels that allow cells to communicate with each other). They found no impact on cell communication at the magnetic field strengths tested (0.4 and 1 mT), contradicting some previous studies that suggested power frequency fields could disrupt this cellular function.
Xiong DF, Liu JW, Li ZX, Zeng GC, Li HL · 2015
Researchers studied 310 electrical workers who regularly inspect power transformers and distribution lines to see if their exposure to extremely low frequency electromagnetic fields caused oxidative stress (cellular damage from harmful molecules). They measured multiple markers of cellular damage and DNA damage in blood samples, comparing the workers to 300 office staff with minimal EMF exposure. The study found no significant differences between the two groups in any of the damage markers tested.
Kesari KK, Luukkonen J, Juutilainen J, Naarala J · 2015
Researchers exposed human brain cells to 50 Hz magnetic fields (the type from power lines) for 24 hours and tracked genetic damage for up to 45 days afterward. They found that the magnetic field exposure caused DNA damage that persisted for at least 30 days, and this damage wasn't prevented by antioxidants, suggesting the fields directly affect cellular genetics rather than just causing oxidative stress.
Jin H, Yoon HE, Lee JS, Kim JK, Myung SH, Lee YS. · 2015
Researchers exposed human lung cells to 60 Hz magnetic fields (1-2 mT) alone and combined with radiation or hydrogen peroxide to test whether EMFs might make cells more vulnerable to genetic damage. The magnetic fields alone caused no genetic damage, and they didn't make the cells more susceptible to damage when combined with other stressors. This suggests that power frequency magnetic fields at these levels don't compromise cellular genetic stability.
Trunk A et al. · 2015
Researchers exposed 25 people to UMTS mobile phone radiation (similar to 3G signals) for 15 minutes while they performed visual tasks, with some participants also given caffeine. While caffeine improved reaction times and brain arousal as expected, the mobile phone radiation had no detectable effects on brain activity or cognitive performance, either alone or when combined with caffeine.
Sauter C et al. · 2015
German researchers exposed 30 healthy young men to TETRA radio signals (used by emergency services) for 2.5 hours at two different power levels to test effects on thinking abilities and well-being. They found no negative impacts on cognitive performance, mood, or physical complaints, with some measures actually showing slight improvement during exposure. This suggests short-term exposure to TETRA signals at these levels doesn't impair mental function in healthy adults.
Salunke BP, Umathe SN, Chavan JG. · 2015
Researchers exposed mice to 2.45 GHz radiofrequency radiation (the same frequency used by WiFi and Bluetooth) for up to 120 days to see if it would cause anxiety, obsessive-compulsive behaviors, or depression-like symptoms. The study found no behavioral changes in the mice across multiple standard tests, even after four months of daily exposure. This suggests that chronic exposure to this common wireless frequency may not directly affect mood or anxiety-related behaviors.
Malek F, Rani KA, Rahim HA, Omar MH · 2015
Malaysian researchers exposed 200 people (half claiming electromagnetic sensitivity) to cell tower signals at 1 volt per meter for short periods and measured cognitive performance, body temperature, heart rate, and blood pressure. They found no statistically significant differences between real exposure and fake exposure in either sensitive or non-sensitive individuals. This suggests that brief exposure to typical cell tower radiation levels doesn't immediately affect these basic body functions or mental performance.
Zalata A et al. · 2015
Researchers exposed human sperm samples from 124 men to cell phone radiation for one hour in laboratory conditions. The radiation significantly reduced sperm movement and increased DNA damage, with the worst effects seen in men who already had fertility problems. This suggests that cell phone radiation may harm male fertility by damaging sperm quality and genetic material.
Sehitoglu I et al. · 2015
Researchers exposed pregnant rats to 900 MHz cell phone radiation for 24 hours daily during pregnancy, then examined the reproductive health of their male offspring at 60 days old. The exposed rats had 13% lower testosterone levels, smaller testes, and increased cell death markers compared to unexposed controls. This suggests that cell phone radiation exposure during pregnancy may harm the developing reproductive system of male offspring.
Sangun O, Dundar B, Darici H, Comlekci S, Doguc DK, Celik S · 2015
Researchers exposed pregnant and newborn female rats to WiFi-frequency radiation (2450 MHz) for one hour daily and tracked their development through puberty. Rats exposed in the womb showed slower growth, delayed puberty, and increased oxidative stress in brain and ovary tissues compared to unexposed controls. This suggests that WiFi radiation during critical developmental periods may disrupt normal reproductive maturation.
Saili L et al. · 2015
Researchers exposed rabbits to WiFi signals (2.45GHz) for one hour and measured their heart function and blood pressure. The WiFi exposure increased heart rate by 22% and blood pressure by 14%, while also disrupting normal heart rhythm patterns. This suggests that common WiFi radiation can directly affect cardiovascular function, even after just brief exposure.
Mahmoudabadi FS, Ziaei S, Firoozabadi M, Kazemnejad A · 2015
Researchers in Iran studied 600 women to examine whether mobile phone use during pregnancy increases the risk of miscarriage. They compared women who had unexplained miscarriages before 14 weeks with those who carried pregnancies past 14 weeks. The study found significant differences in mobile phone usage patterns between the two groups, with higher phone use associated with increased miscarriage risk.
Geronikolou SA et al. · 2015
Researchers studied how children's stress hormone systems respond to cell phone calls after experiencing mental stress. They found that children who regularly use cell phones had different cortisol (stress hormone) patterns compared to occasional users when making a 5-minute phone call after a stressful task. This suggests that frequent cell phone use may alter how young people's bodies handle stress.
Gandhi G, Kaur G, Nisar U. · 2015
Researchers studied 63 people living within 300 meters of a cell phone tower and compared their DNA damage to 28 people living farther away. They found significantly more genetic damage (DNA breaks and mutations) in the blood cells of those living near the tower, where radiation levels exceeded safety limits. Women showed more DNA damage than men, and the amount of damage correlated with how close people lived to the tower and how much they used their phones.
Ulubay M et al. · 2015
Researchers exposed pregnant rats to 900 MHz electromagnetic fields (the frequency used by older cell phones) and examined their offspring's kidneys at four weeks old. They found that prenatal EMF exposure caused the kidneys to grow abnormally larger while reducing the number of glomeruli (tiny filtering units essential for kidney function). Importantly, supplementing with melatonin or omega-3 fatty acids during pregnancy prevented these harmful effects.
Topal Z et al. · 2015
Researchers exposed pregnant rats to cell phone radiation (900 MHz) for one hour daily during the final third of pregnancy, then examined their male offspring at three weeks old. The exposed pups showed significant liver damage, including cellular death and increased oxidative stress markers. This suggests that prenatal exposure to wireless radiation may cause lasting organ damage that persists after birth.
Sokolovic D et al. · 2015
Researchers exposed rats to microwave radiation for 4 hours daily and found it caused oxidative stress and DNA damage in testicular tissue. However, when rats were also given melatonin (a natural hormone), it prevented much of this damage by reducing harmful chemical reactions and protecting genetic material. This suggests melatonin may offer some protection against microwave radiation's harmful effects on reproductive organs.
Olgar Y et al. · 2015
Researchers exposed rats to 2.1 GHz radiofrequency radiation (similar to cell phone frequencies) for 2 hours daily over 10 weeks and studied how their heart muscle cells responded. While the basic heart muscle contractions remained normal, the cells became less responsive to adrenaline-like stress hormones, and nitric oxide levels in the heart increased significantly. This suggests that chronic RF exposure may alter how the heart responds to stress, even when basic heart function appears unchanged.
Odacı E, Özyılmaz C. · 2015
Researchers exposed male rats to 900 MHz electromagnetic fields (the same frequency used by cell phones) for one hour daily over 30 days and found significant damage to testicular tissue and function. The EMF-exposed rats showed structural damage to sperm-producing tubes, increased cell death, and reduced levels of important antioxidants that protect against cellular damage. This suggests that chronic exposure to cell phone-level radiation may harm male reproductive health.
