Researchers exposed two important enzymes (lactoperoxidase and horseradish peroxidase) to 900 MHz radiofrequency radiation, the same frequency used by many cell phones. The radiation altered the enzymes' structure and function, changing how they catalyzed chemical reactions and affecting the stability of free radicals they produce. This suggests that RF radiation can directly interfere with fundamental biological processes at the molecular level.

Researchers exposed pregnant rats to cell phone and Wi-Fi radiation for 60 minutes daily throughout pregnancy and tracked their offspring for multiple generations. They found that this exposure significantly decreased essential reproductive hormones (prolactin, estrogen, and progesterone) in both mothers and offspring, while increasing oxidative stress damage in the uterus. This suggests that everyday wireless radiation exposure during pregnancy could disrupt hormonal balance and reproductive health across generations.
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.
Shivashankara AR et al. · 2015
Researchers analyzed saliva samples from college students to compare light and heavy cell phone users. They found that heavy users had significantly higher levels of stress enzymes and oxidative damage markers in their saliva. This suggests that frequent cell phone use may trigger cellular stress responses that can be measured through simple saliva tests.

Researchers exposed rats to mobile phone radiation, ringtones, and vibrations for 10 minutes daily over 4 weeks to study effects on anxiety and brain chemistry. All exposed groups showed increased anxiety-like behavior, while rats exposed to ringtones or combined ringtone/vibration also had reduced levels of catalase, an important antioxidant enzyme in the brain. This suggests that mobile phone emissions may affect both behavior and the brain's ability to protect itself from cellular damage.

Researchers exposed young male rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwaves) for 3 hours daily over 30 days and found significant damage to their testes. The radiation increased oxidative stress, triggered inflammation, and reduced sperm production in the animals' reproductive organs. However, when rats received gallic acid (a natural antioxidant) alongside the radiation exposure, it protected against much of this testicular damage.
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.
Marconi A et al. · 2015
Researchers exposed 18 volunteers to GSM mobile phone signals for 30 minutes and measured oxidative stress markers in their blood and breath. They found that phone exposure changed how these biological markers were organized in the body, suggesting the radiation interacts with cellular processes. While the study doesn't prove harm or safety, it provides evidence that mobile phone signals do affect biological systems at the cellular level.

Researchers exposed rats to 900 MHz mobile phone radiation for 4 hours daily over 18 days and found significant liver damage. The radiation caused increased oxidative stress (cellular damage from harmful molecules), liver cell death, and visible tissue damage including cell swelling and death. This suggests that prolonged exposure to mobile phone frequencies may harm liver function through cellular stress pathways.
Lewicka M et al. · 2015
Polish researchers exposed human blood platelets to electromagnetic fields from car electronics, physiotherapy equipment, and LCD monitors for 30 minutes. All three EMF sources triggered oxidative stress (cellular damage from free radicals) in the platelets, with car electronics causing the most severe effects. This suggests that common electronic devices may contribute to cellular damage that could lead to various health problems.
Kazemi E et al. · 2015
Researchers exposed blood cells from 13 healthy volunteers to 900 MHz radiation (the frequency used by cell phones) for 2 hours and measured cellular damage. They found that exposure significantly increased reactive oxygen species (ROS) - harmful molecules that damage cells - in monocytes, a type of immune cell. This suggests that cell phone radiation can trigger oxidative stress in immune system cells.
İkinci A et al. · 2015
Researchers exposed young male rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during adolescence and examined their spinal cords. They found significant damage including breakdown of the protective myelin sheaths around nerve fibers, increased oxidative stress markers, and structural abnormalities in nerve cells. This suggests that radiofrequency exposure during critical developmental periods may harm the developing nervous system.
Hancı H et al. · 2015
Researchers exposed pregnant rats to 900 MHz cell phone radiation for one hour daily and examined the immune organs (spleen and thymus) of their male offspring at 21 days old. The prenatal radiation exposure caused significant oxidative damage and structural abnormalities in these critical immune system organs. This suggests that EMF exposure during pregnancy may compromise immune system development in offspring.
Bin-Meferij MM, El-Kott AF · 2015
Male rats exposed to cell phone radiation (900 MHz) for one hour daily showed damaged sperm quality, reduced sperm count, and abnormal testicular tissue after seven days. This research suggests that cell phone radiation may harm male fertility in mammals.
Barteri M et al. · 2015
Researchers exposed two important enzymes (lactoperoxidase and horseradish peroxidase) to 900 MHz radiofrequency radiation and found that the exposure caused structural changes to the enzymes' active sites. These changes affected how the enzymes functioned and how they formed free radicals. This matters because these same types of enzymes play crucial roles in human cellular processes.
Osera C et al. · 2015
Researchers exposed neuroblastoma cells (a type of brain cancer cell) to pulsed electromagnetic fields for short periods over several weeks, then tested how well the cells handled oxidative stress (cellular damage from harmful molecules). They found that the EMF pre-exposure increased the cells' natural antioxidant defenses and made them more resistant to damage from hydrogen peroxide, suggesting that certain EMF exposures might help cells protect themselves against harmful oxidation.
Ozgur E et al. · 2015
Scientists exposed guinea pigs to cell phone radiation (900 MHz) for seven days and found it significantly reduced SOD, a protective antioxidant enzyme in liver tissue. Surprisingly, two common antioxidant supplements caused cellular damage when used alone, showing radiation's complex effects on cellular protection.

Scientists exposed hamster cells to cell phone radiation (1800 MHz) for 10-60 minutes. Even brief 10-minute exposures significantly increased harmful molecules called reactive oxygen species that can damage cells, showing that phone radiation disrupts cellular balance.
Holovská K et al. · 2015
Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 3 weeks at power levels of 2.8 mW/cm². They found liver damage including inflammation, blood vessel dilation, and cellular changes including fat accumulation and dying liver cells. This suggests that chronic exposure to common microwave frequencies may harm liver function.
Furtado-Filho OV et al. · 2015
Brazilian researchers exposed pregnant rats and their newborns to cell phone frequency radiation (950 MHz) for 30 minutes daily throughout pregnancy and after birth. They found that 6-day-old exposed rats showed protein damage specifically in the right side of their brain, plus lower blood sugar levels. Newborn rats showed no effects, suggesting developing brains become more vulnerable to EMF damage as they mature.
Djordjevic B et al. · 2015
Serbian researchers exposed rats to 900 MHz microwave radiation (similar to cell phone frequencies) for 4 hours daily over 20-60 days and found significant liver damage, including increased oxidative stress and cellular damage markers. When rats were also given melatonin supplements, the treatment partially protected against some of the radiation-induced liver damage. This suggests that microwave radiation can harm liver function, but natural antioxidants like melatonin may offer some protection.
Cao H, Qin F, Liu X, Wang J, Cao Y, Tong J, Zhao H. · 2015
Researchers exposed rats to cell phone-level radiation for 2 hours daily over 32 days. The radiation disrupted natural 24-hour cycles of antioxidant production, with nighttime exposures causing the biggest drops in protective compounds like melatonin. This suggests RF radiation may interfere with the body's internal clock.
Liu X et al. · 2015
Researchers exposed rats with artificially induced Alzheimer's disease symptoms to 50-Hz electromagnetic fields (the same frequency as household power lines) for 60 days. The EMF exposure actually improved the rats' memory and reduced brain damage associated with Alzheimer's disease. This suggests that certain types of electromagnetic field exposure might have protective effects on the brain, contrary to concerns about EMF causing neurological harm.
