Researchers exposed mice to cell phone radiation at 900 MHz for either one hour or repeatedly over two years, then examined their brains for signs of microglial activation (immune cells that respond to brain stress or damage). They found no evidence that either short-term or long-term radiofrequency exposure activated these immune cells, even though the same cells responded strongly when brain tissue was physically damaged. This suggests that cell phone radiation at these levels may not trigger the brain's stress response mechanisms.

British researchers examined whether children whose mothers lived near cell phone towers during pregnancy had higher rates of cancer. They compared 1,397 children with cancer to 5,588 healthy children, analyzing the distance from their birth address to nearby cell towers and the radiofrequency exposure levels. The study found no increased cancer risk associated with proximity to cell towers or higher exposure levels during pregnancy.

Australian researchers followed 236 seventh-grade students for one year to see if mobile phone use affected their thinking abilities. They found some small changes in how quickly students responded to computer tests, but these changes were likely due to statistical variations rather than actual phone exposure effects. The study suggests that mobile phone use doesn't meaningfully impact cognitive function in adolescents over a one-year period.
Kwon MS et al. · 2010
Researchers tested whether cell phone radiation affects children's ability to process sounds by measuring brain activity in 17 children aged 11-12 while they were exposed to 902 MHz signals from a GSM phone. The study found no significant changes in the brain's auditory processing or sound memory functions during short exposures (12 minutes total). However, the researchers noted their study could only detect large effects, meaning smaller impacts might have gone unnoticed.

Researchers exposed brain immune cells called microglia to cell phone radiation at levels up to 2.0 W/kg for two hours to see if it would activate an inflammatory response. They found no signs of activation or increased production of inflammatory molecules compared to unexposed cells. This suggests that moderate levels of cell phone radiation don't trigger brain inflammation in laboratory conditions.

German researchers used personal dosimeters to measure radiofrequency radiation exposure in nearly 3,000 children and adolescents over 24 hours, then tracked acute symptoms like headaches and concentration problems. While they found a few statistically significant associations between higher RF exposure and symptoms, the researchers concluded these were likely due to chance rather than actual health effects because the results weren't consistent and disappeared when analyzing the highest-exposed participants separately.

Researchers exposed mice to 900 MHz cell phone radiation for either 60 minutes or five days a week for two years, then examined their brains for signs of microglial activation - a cellular stress response that occurs when brain tissue is damaged. They found no evidence of brain cell stress or activation at either exposure duration, even at radiation levels much higher than typical cell phone use.
Vrijheid M et al. · 2010
Spanish researchers studied 587 pregnant women who used or didn't use cell phones during pregnancy, then tested their children's brain development at 14 months using standard infant development tests. Children whose mothers used cell phones during pregnancy showed only small differences in development scores compared to children of non-users, with no clear pattern based on how much mothers used their phones. The study found little evidence that maternal cell phone use during pregnancy harms early brain development in infants.

Italian researchers measured brain wave patterns in elderly and young adults while exposed to cell phone radiation for 45 minutes. They found that older adults showed significantly increased synchronization between the left and right brain hemispheres in the alpha frequency range (8-12 Hz) during phone exposure, while younger subjects showed minimal changes. This suggests that aging brains may be more vulnerable to electromagnetic field effects from mobile devices.
Thomas S et al. · 2010
Researchers followed 236 Australian teenagers for one year to see how mobile phone use affected their thinking abilities. Students who used their phones more showed faster response times on computer-based cognitive tests, though the researchers noted this improvement might be due to statistical factors rather than actual phone effects. The study found changes in reaction speed but not accuracy on mental tasks.

Researchers measured actual radiofrequency radiation exposure in over 3,000 German children and teenagers using personal dosimeters for 24 hours, then assessed their behavior using standardized questionnaires. They found that adolescents with the highest RF exposure were 2.2 times more likely to have behavioral problems, while both children and adolescents showed nearly 3 times higher rates of conduct problems. This matters because it's one of the first studies to use objective exposure measurements rather than relying on self-reported phone use.
Maganioti AE et al. · 2010
Researchers measured brain activity in 39 people performing a memory task while exposed to mobile phone-like radiofrequency radiation. They found that RF exposure altered brain wave patterns differently in men and women, essentially erasing the normal gender differences seen in brain electrical activity. The study reveals that even brief RF exposure can measurably change how our brains process information.

Researchers analyzed 33 studies examining whether mobile phone use increases cancer risk, with most focusing on brain tumors. They found that current epidemiological studies cannot properly detect cancer risks because researchers lack proper exposure measurements, most users haven't used phones long enough to develop cancer, and scientists don't know which specific cancers to look for. Despite these limitations, the overall evidence suggests mobile phone use may increase cancer risk, though the exact magnitude remains unclear.

They found a few statistically significant associations between higher RF exposure and symptoms, but these results were inconsistent and disappeared when analyzing the highest-exposed participants. The researchers concluded the observed effects likely occurred by chance rather than representing true causal relationships.

Swedish researchers studied 346 people who died from malignant brain tumors and found those who used mobile phones for more than 10 years had 2.4 times higher risk of developing these deadly brain cancers. The risk climbed even higher for people with over 2,000 hours of lifetime mobile phone use, reaching 3.4 times normal risk. This study is particularly significant because it examined deceased cases, eliminating the possibility that living brain tumor patients might wrongly blame their phones for their illness.
Croft RJ et al. · 2010
Researchers exposed 103 people across three age groups (teens, young adults, and elderly) to 2G and 3G cell phone signals while measuring their brain waves. They found that only young adults (ages 19-40) showed changes in their alpha brain waves when exposed to 2G signals, while teenagers and elderly participants showed no effects from either 2G or 3G exposure. This suggests that brain sensitivity to cell phone radiation varies significantly by age.
Crespo-Valero P et al. · 2010
Researchers developed a new computer modeling method to precisely map how electromagnetic fields from sources like cell phones are absorbed in specific brain regions. Using detailed brain anatomy maps, they can now track exactly which parts of the brain receive the highest radiation exposure. This breakthrough allows scientists to better understand which brain areas are most affected during phone use and improve safety testing for wireless devices.

Researchers used MRI-based head models to compare how cell phone radiation is absorbed in children's brains versus adults' brains. They found that children absorb significantly more radiation in key brain regions like the cortex, hippocampus, and hypothalamus (over 3 dB higher), with bone marrow showing even greater increases (over 10 dB higher). This happens because children's smaller heads place these tissues closer to the phone, even though overall head absorption remains similar between age groups.

Polish researchers measured brain waves in 15 volunteers while they were exposed to GSM cell phone radiation. They found that a specific brain wave called P300, which reflects cognitive processing, showed reduced amplitude (strength) during EMF exposure but returned to normal when the exposure stopped. This suggests that cell phone radiation can temporarily alter brain function during active use.

Researchers used computer modeling to study how EEG electrodes and wires on the head change the way cell phone radiation is absorbed by the brain. They found that while overall radiation absorption stayed roughly the same, the metal electrodes created hotspots where local tissue absorbed 40 times more radiation in the brain and 100 times more in the skin. This means studies that measure brain activity during cell phone exposure might be seeing effects from these concentrated radiation hotspots rather than the phone's normal radiation pattern.

Researchers exposed rats to 900 MHz cell phone radiation and found it disrupted protective brain enzymes. When rats also received vitamin C, the antioxidant helped restore some enzyme function. This suggests phone radiation creates harmful oxidative stress in brain tissue that antioxidants might help counteract.
Volkow ND et al. · 2010
Researchers exposed 15 healthy people to magnetic fields inside MRI machines and measured brain activity using glucose metabolism scans. They found that stronger magnetic field exposure caused measurable decreases in brain activity in specific regions, with the strongest fields producing the largest reductions. This demonstrates that magnetic fields can directly alter how the brain functions, even without people feeling any immediate effects.
Vecchio F et al. · 2010
Researchers exposed 16 elderly and 5 young adults to GSM mobile phone emissions for 45 minutes while measuring their brain waves with EEG. They found that elderly subjects showed significantly increased synchronization between brain hemispheres in the alpha frequency range (8-12 Hz) during phone exposure, while young subjects showed less pronounced effects. This suggests that aging brains may be more susceptible to electromagnetic field interference from mobile phones.

German researchers studied over 3,000 children and teens, measuring their actual radiofrequency EMF exposure from cell towers and wireless networks over 24 hours using personal dosimeters. They found that adolescents with the highest RF exposure levels were more than twice as likely to show behavioral problems, particularly conduct issues like aggression or rule-breaking. The exposure levels were well below safety limits, suggesting behavioral effects may occur at everyday environmental levels.
Maganioti AE et al. · 2010
Researchers studied how mobile phone radiation affects brain activity patterns during memory tasks in 39 healthy adults. They found that radiofrequency exposure at mobile phone frequencies (900 MHz and 1,800 MHz) altered normal gender differences in brain electrical activity, particularly affecting how men and women's brains processed information differently. This suggests that mobile phone radiation can modify fundamental patterns of brain function.
