Researchers compared the cognitive performance of 100 military radar operators to 57 unexposed controls, testing their reaction times and short-term memory abilities. They found radar workers had significantly faster reaction times but substantially worse memory performance across all measures tested. This suggests that occupational exposure to high-powered radar microwaves (2-18 GHz) may alter brain function in ways that could both help and harm job performance.

Researchers exposed rats to cell phone radiation for different durations daily over three months and measured their blood sugar levels. Rats exposed for more than 15 minutes per day developed significantly higher fasting blood glucose and insulin levels, along with increased insulin resistance (when cells don't respond properly to insulin). This suggests that regular cell phone radiation exposure may disrupt normal blood sugar regulation, potentially contributing to diabetes risk.

Greek researchers measured radiofrequency radiation levels in 40 indoor locations across homes, offices, and schools over an 18-month period using personal dosimeters. They found that exposure levels in Greece were higher than similar studies across Europe, with cell tower signals dominating workplaces and schools during the day, while WiFi and cordless phones created the highest exposures in homes during evening hours. While all measurements remained below international safety guidelines, the study reveals that our indoor environments contain measurable RF radiation from multiple wireless sources throughout the day.

Researchers studied college students to examine how cell phone use affects physical fitness and activity levels. They found that students who used their phones more had significantly lower cardiorespiratory fitness, even after accounting for other factors like body fat and exercise motivation. The study suggests this happens because heavy phone users often skip physical activities to use their devices, and phone use tends to be part of a broader pattern of sedentary behavior.

Swiss researchers developed a method to measure total daily RF-EMF exposure by combining radiation from mobile phones (near-field) and cell towers (far-field sources). They found that your own mobile phone dominates your daily EMF exposure, contributing far more radiation to your body than environmental sources like cell towers. The study showed that older GSM phones created higher exposure levels than newer UMTS phones due to their higher power output.

Turkish researchers exposed rats to cell phone radiation for 8 hours daily over 20 days using a Philips phone with high radiation output. They found significant kidney damage including damaged filtering units (glomeruli), swollen tissue spaces, and inflammation in exposed rats compared to unexposed controls. The damage persisted even 20 days after exposure ended, suggesting lasting effects from intensive cell phone use.

Turkish researchers studied 500 pregnant women to see if using electronic devices affected birth outcomes. They found that mothers who used mobile phones or computers during pregnancy were significantly more likely to deliver prematurely (before 37 weeks), though device use didn't affect birth weight. The study suggests everyday EMF exposure from common devices may influence pregnancy duration.

Researchers exposed rats to WiFi radiation (2.45 GHz) for one hour daily over 21 days and found it created a diabetes-like condition by damaging the body's natural antioxidant defenses in the liver and kidneys. The WiFi exposure reduced key protective enzymes by 33-68% and increased cellular damage markers by up to 51%. When researchers gave the rats olive leaf extract, it prevented most of the metabolic disruption and restored the protective enzymes, suggesting that WiFi radiation causes harm through oxidative stress.

Researchers exposed pregnant rabbits and their offspring to cell phone-like radiation (1800 MHz GSM) for 15 minutes daily and measured blood chemistry changes in the baby rabbits. They found that even brief daily exposures caused oxidative stress (cellular damage from free radicals) and altered blood chemistry parameters, with different effects in male versus female offspring. The findings suggest that developing animals may be particularly vulnerable to radiofrequency radiation during critical growth periods.
Bodera P et al. · 2013
Researchers exposed rats to cell phone radiation (1800 MHz) for 15 minutes and found it significantly reduced the blood's ability to fight harmful free radicals. This antioxidant damage occurred in both healthy and inflamed animals, suggesting cell phone radiation may weaken natural cellular defenses.

Researchers measured radiation from people's phones while traveling, comparing phones turned off versus standby mode. They found phones constantly emit radiation even when not in use, with car exposure levels orders of magnitude higher than with phones off, challenging assumptions about phone radiation safety.

French researchers exposed young rats to cell phone radiation (900 MHz) for five weeks and found disrupted sleep patterns, increased daytime eating, and impaired blood vessel function affecting temperature control. These changes suggest chronic RF exposure interferes with basic biological processes controlling energy use.
Estenberg J, Augustsson T. · 2013
Swedish researchers developed a mobile monitoring system to measure radiofrequency radiation levels across different environments, collecting over 70,000 measurements in rural, urban, and city areas. They found that radiation levels increased dramatically from rural to urban settings, with city areas showing 150 times higher exposure than rural areas. The study demonstrates how cell phone towers create significant differences in public RF exposure depending on where you live and work.

Researchers measured radiofrequency radiation levels at various distances from cell phone towers in Nigeria using calibrated equipment. They found the highest radiation levels occurred at 50-200 meters from the towers, with maximum readings of 2,972 µW/m². All measured levels were below international safety guidelines, suggesting people living near these towers face relatively low RF exposure.

Researchers exposed mice to extremely low-frequency magnetic fields (ELF-MF) at 3 milliTesla for 200 hours to study effects on mood and stress hormones. The exposed mice showed depression-like behaviors, increased anxiety, and elevated levels of corticosterone (a stress hormone), suggesting that chronic magnetic field exposure may affect mental health and stress response systems.

Researchers exposed rats to power line frequency magnetic fields while giving them manganese, a potentially toxic metal. The magnetic field exposure significantly increased manganese buildup in the brain, kidneys, and liver, suggesting EMF exposure may impair the body's ability to eliminate toxic substances.

Researchers studied whether extremely low frequency magnetic fields could prevent bone loss in rats with spinal cord injuries. They exposed injured rats to 50 Hz magnetic fields (17.96 microTesla) for 2 hours daily over 8 weeks and found the treatment significantly prevented osteoporosis, maintaining bone density and mineral content compared to untreated injured rats. This suggests that specific magnetic field therapy might help preserve bone health after spinal cord injury.

Researchers tested whether people claiming electromagnetic hypersensitivity (EHS) could actually detect cell phone radiation or experience symptoms from it. They exposed 17 EHS subjects and 20 healthy controls to real and fake WCDMA phone signals for 32 minutes while monitoring heart rate, breathing, and symptoms. Neither group showed any physiological changes or could reliably tell when they were being exposed to real radiation.

Researchers analyzed the health records of US embassy staff in Moscow who were exposed to microwave radiation (2.5-4.0 GHz) from 1953-1976, comparing them to staff at other Eastern European embassies. The study found no adverse health effects from the microwave exposure, which was at levels similar to or higher than current cell phone tower emissions. This Cold War incident provides unique long-term data on radiofrequency exposure effects in humans.
Sokolovic D et al. · 2012
Researchers exposed rats to microwave radiation from mobile phones for 4 hours daily over 20-60 days and found the animals lost significant body weight and developed anxiety-like behaviors including agitation and irritability. When the same rats were given melatonin (a natural hormone and antioxidant), it prevented the weight loss and reduced the stress-related behaviors caused by the radiation exposure.

Iranian researchers studied 41 dentists and dental students, comparing cortisol levels (a stress hormone) between those who used magnetostrictive dental scalers and those who didn't. They found that dentists exposed to the electromagnetic fields from these common dental tools had significantly lower cortisol levels by the end of their workday. This matters because cortisol helps regulate blood pressure, cardiovascular function, and immune system response, so chronically low levels could affect health.
