Swedish researchers exposed 20 people who experience symptoms from mobile phones (like headaches or fatigue) and 20 people without such symptoms to 30 minutes of GSM cell phone radiation at 1 W/kg SAR. While the radiation exposure itself didn't cause measurable changes in either group, the symptomatic individuals showed different nervous system patterns during cognitive tests, suggesting their autonomic nervous systems may respond differently to stress regardless of EMF exposure.

Swedish researchers exposed 20 people who experience symptoms from mobile phones and 20 people without symptoms to 900 MHz cell phone radiation for 30 minutes at levels typical of phone use. While the radiation didn't cause immediate measurable changes in either group, the symptomatic individuals showed different nervous system patterns during cognitive tests, suggesting their autonomic nervous systems may function differently regardless of radiation exposure.

Researchers exposed human immune cells to cell phone radiation at 1800 MHz (the frequency used by GSM networks) to see if it would trigger the production of harmful free radicals or stress proteins. Even at high exposure levels up to 2.0 W/kg, the radiation did not cause any significant increase in free radical production or stress protein expression in the cells. This suggests that cell phone radiation at these levels may not trigger the type of cellular damage that free radicals can cause.

Researchers exposed rats to cell phone frequency radiation and found it caused brain damage through oxidative stress in two key brain regions. However, giving rats melatonin beforehand prevented damage in the hippocampus, suggesting antioxidants may protect against microwave radiation's harmful effects.

Australian researchers measured radiofrequency radiation levels around 60 cell phone towers across five cities, testing distances from 50 to 500 meters away. They found that all measured exposure levels were well below government safety limits, with the highest reading reaching only 0.2% of the allowed public exposure threshold. This study provides baseline data on how much RF radiation people actually encounter from cell towers in everyday environments.

Researchers used computer modeling to examine how radiofrequency energy from cell phones is absorbed by children's heads compared to adults, accounting for the fact that children's tissues have higher water content. They tested common cell phone frequencies (900, 1800, and 2450 MHz) and found that even when tissue water content was increased by 5-20% to simulate children's physiology, energy absorption (SAR) varied by only about 5% on average. The study suggests that tissue composition differences between children and adults may have less impact on RF absorption than previously thought.

Researchers exposed human blood cells to cell phone radiation at 935 MHz (similar to 2G networks) for 24 hours to test whether it damages DNA or makes cells more vulnerable to DNA damage from X-rays. Using multiple standard tests on blood samples from 14 donors, they found no evidence that the radiation caused genetic damage on its own or made X-ray damage worse. The study tested radiation levels of 1-2 watts per kilogram, which are near the upper limits of what brain tissue absorbs during some cell phone calls.
Stronati L et al. · 2006
Italian and British researchers exposed human immune cells (lymphocytes) to 935 MHz cell phone radiation for 24 hours at levels similar to what tissues experience during phone use. Using multiple DNA damage tests, they found no genetic damage from the radiation alone, and the radiation didn't make X-ray damage worse. This suggests that 24-hour exposure to this type of cell phone radiation doesn't directly break DNA or interfere with DNA repair.
Sakuma N et al. · 2006
Researchers exposed human brain and lung cells to 2.1425 GHz radiofrequency radiation at levels up to 10 times higher than public safety limits for up to 24 hours. They found no DNA damage in either cell type, even at the highest exposure levels tested. This suggests that cell phone tower radiation at these frequencies doesn't break DNA strands under laboratory conditions.
Merola P et al. · 2006
Italian researchers exposed neuroblastoma cells (a type of nerve cell) to 900 MHz radiofrequency radiation at levels higher than occupational safety limits for up to 72 hours. They found no significant changes in cell growth, death, or differentiation processes. This suggests that even at elevated exposure levels, this type of cell phone radiation may not directly damage these particular nerve cells in laboratory conditions.

Researchers used computer simulations to compare how much radiofrequency radiation children's heads absorb from mobile phones compared to adults. They found that 10-year-old children absorb over 60% more radiation in their heads than adults when using the same phone. This happens because children have smaller heads, thinner skulls, and different tissue properties that allow deeper radiation penetration.
Krause CM et al. · 2006
Finnish researchers studied how mobile phone radiation affects brain activity in 15 children (ages 10-14) while they performed memory tasks. When exposed to 902 MHz radiation from an active phone, the children showed measurable changes in their brain wave patterns during both memory encoding and recognition phases. This demonstrates that cell phone radiation can directly alter brain function in developing minds, even during short-term exposure.

Researchers exposed human breast cancer cells (MCF-7) to cell phone radiation at 1800 MHz for 24 hours to see if it changed gene and protein activity. While initial tests suggested some genes might be affected, follow-up verification tests found no consistent changes. The study concluded that cell phone radiation at these levels does not produce convincing evidence of biological effects on cellular gene or protein expression.

German researchers exposed human immune cells (Mono Mac 6 cells) to cell phone radiation at 1,800 MHz for 12 hours to see if it would cause cell death or disrupt normal cell division cycles. They found no statistically significant effects on cell death, cell division, or DNA synthesis compared to unexposed control cells. This suggests that at the tested exposure level, cell phone-type radiation did not harm these particular immune cells in laboratory conditions.

Researchers exposed human immune cells to cell phone radiation at 1950 MHz for 8 hours to see if it affected immune function. They tested multiple immune system markers including cytokine production (chemical messengers that coordinate immune responses) and gene activity. The study found no statistically significant effects on any immune parameters tested.
Hirose H et al. · 2006
Researchers exposed human brain and lung cells to radiofrequency radiation at 2.14 GHz (similar to cell tower frequencies) for up to 48 hours to see if it would trigger cell death or DNA damage responses. They tested exposure levels from 0.08 to 0.8 watts per kilogram - with the lowest level matching international safety limits for public exposure. The study found no evidence that this RF radiation caused cells to die, damaged DNA, or activated stress response pathways even at levels 10 times higher than safety guidelines.
Stankiewicz W et al. · 2006
Researchers exposed human immune cells to 900 MHz microwave radiation (similar to GSM cell phone signals) at very low power levels and found that the radiation significantly increased immune cell activity. The exposed cells showed stronger responses to immune stimulants compared to unexposed control cells. This suggests that even weak microwave radiation can alter how our immune system functions.
Stankiewicz W et al. · 2006
Polish researchers exposed human immune cells to 900 MHz GSM cell phone signals at very low power levels (SAR 0.024 W/kg) and found that the microwave exposure significantly increased immune cell activity. The exposed cells showed stronger responses to immune stimulants and higher activity levels compared to unexposed control cells. This suggests that even low-level cell phone radiation can alter how your immune system functions at the cellular level.
Wang J et al. · 2006
Researchers exposed human brain cells (A172) to microwave radiation at 2450 MHz (the same frequency used in microwave ovens and WiFi) to see if it triggers cellular stress responses. They found that extremely high radiation levels (100-200 W/kg) caused specific stress protein changes that couldn't be explained by heating alone. This suggests microwave radiation may cause biological stress in cells through mechanisms beyond just warming tissue.
Takashima Y et al. · 2006
Japanese researchers exposed cells to 2.45 GHz radiation (WiFi frequency) at different power levels. Cell growth remained normal up to 100 W/kg, but died at 200 W/kg when temperatures exceeded 104°F, showing cellular damage occurs only from significant heating effects.
Joubert V et al. · 2006
French researchers exposed human brain cells to cell phone radiation at 900 MHz for 24 hours to see if it would trigger cell death (apoptosis). They tested two exposure levels - one mimicking typical phone use and another eight times higher. The study found no increase in brain cell death at either exposure level, suggesting that 24-hour exposure to cell phone radiation does not kill these particular brain cells.

Researchers exposed pregnant mice to cell phone-like radiation (900 MHz) for one hour daily throughout pregnancy to see if it would damage the blood-brain barrier in developing fetal brains. The blood-brain barrier is a protective filter that prevents harmful substances from entering brain tissue. They found no damage to this protective barrier in any brain region examined, suggesting the radiation exposure did not compromise brain protection during development.
Nasta F et al. · 2006
Researchers exposed mice to cell phone radiation (900 MHz GSM signals) for 2 hours daily over 4 weeks to test whether it affects immune system function, specifically B-cells that produce antibodies to fight infections. They found no changes in B-cell development, antibody production, or immune responses compared to unexposed mice. This suggests that this level of cell phone radiation exposure doesn't impair the immune system's ability to protect against disease.
Calcagnini G et al. · 2006
Italian researchers tested whether GSM mobile phones could interfere with medical infusion pumps that deliver medications to patients. They found that 6 out of 8 volumetric pumps and 1 out of 4 syringe pumps malfunctioned when exposed to phones at maximum power within 30 centimeters. This matters because pump malfunctions in hospitals could deliver incorrect medication doses to critically ill patients.

Researchers exposed Chinese hamster lung cells to cell phone radiation (1800 MHz GSM) at levels similar to what your phone produces during heavy use. After 24 hours of intermittent exposure, they found a 35% increase in DNA damage markers compared to unexposed cells. This suggests that prolonged cell phone radiation exposure may cause genetic damage at the cellular level.
