Researchers calculated how much radiofrequency energy from smart meters gets absorbed by human bodies. Children absorbed the most energy, especially when within 15 centimeters of 2.4 GHz meters. Though levels stayed below safety limits, the study confirms smart meters cause measurable energy absorption in tissue.

Researchers tested whether long-term mobile phone use affects hearing by comparing the phone-using ear to the non-phone-using ear in 40 medical students who had used phones for over 4 years. They found no differences in hearing tests or brain response measurements between the two ears, even among heavy users (more than 60 minutes daily). The study suggests that chronic mobile phone exposure at the ear doesn't impair auditory function.

Researchers studied 155 military personnel exposed to radar frequencies of 8-12 GHz and 12.5-18 GHz to measure how electromagnetic fields affect melatonin (the sleep hormone) and serotonin (a mood chemical) in their blood. Workers exposed to the higher frequency range (12.5-18 GHz) showed significantly lower melatonin levels and higher serotonin levels, especially those with more than 10 years of exposure. This suggests that long-term exposure to certain radar frequencies can disrupt the body's natural hormone balance.

Researchers measured radiofrequency radiation from cell phone towers in different neighborhoods of Basel and Amsterdam using portable meters. They found that downtown and business areas had radiation levels of 0.30 to 0.53 V/m, while residential areas had lower levels of 0.09 to 0.41 V/m. The study demonstrated that these measurements were highly consistent day-to-day, making portable meters a reliable tool for assessing cell tower radiation exposure in urban environments.

Researchers exposed mice to cell phone radiation (900-1900 MHz) for 48 minutes daily over six months and examined their kidneys under a microscope. The study found significant structural damage to kidney tissue, including enlarged spaces in filtering units (glomeruli) and damaged tubules that process urine. This suggests that chronic exposure to cell phone-level radiation may harm kidney function at the cellular level.
Pelletier A et al. · 2013
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.

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.
Kitaoka K, Kitamura M, Aoi S, Shimizu N, Yoshizaki K. · 2013
Researchers exposed mice to extremely low frequency magnetic fields (ELF-MF) at 3 milliTesla for 200 hours and measured their behavior and stress hormone levels. The exposed mice showed significantly more depression and anxiety-like behaviors, along with elevated levels of the stress hormone corticosterone. This suggests that chronic exposure to strong magnetic fields may affect mental health and stress response systems.
Pelletier A et al. · 2013
French researchers exposed young rats to cell phone-frequency radiation for five weeks and found disrupted sleep patterns, reduced blood flow to extremities, and increased daytime eating. These changes suggest that chronic radiofrequency exposure can interfere with the body's natural energy regulation systems.
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.
Bodera P et al. · 2012
Polish researchers exposed rats to cell phone frequency radiation (1800 MHz) and found it interfered with tramadol, a common painkiller used for moderate to severe pain. The electromagnetic fields didn't change pain levels on their own, but they significantly reduced the effectiveness of the pain medication 30 minutes after injection. This suggests that EMF exposure from devices like cell phones might interfere with how our bodies process certain medications.
Breckenkamp J et al. · 2012
German researchers measured EMF exposure in 1,348 bedrooms nationwide. They found cordless phones and WiFi devices created 82% of nighttime EMF exposure, though levels were extremely low and well below safety limits. This shows bedroom EMF exposure is widespread but typically minimal during sleep.
Sokolovic D et al. · 2012
Researchers exposed rats to mobile phone radiation for 4 hours daily over 60 days and found the animals lost significant body weight and developed anxiety-like behaviors including agitation and irritability. When rats were given melatonin (a natural hormone) along with the radiation exposure, these negative effects were largely prevented, suggesting melatonin may offer protective benefits against microwave radiation damage.
Bodera P et al. · 2012
Polish researchers exposed rats to cell phone-frequency electromagnetic fields (1500 MHz and 1800 MHz) for 15 minutes and tested how well the painkiller tramadol worked afterward. While the EMF exposure alone didn't change pain sensitivity, it significantly reduced tramadol's pain-relieving effects when the two were combined. This suggests that EMF exposure from devices like cell phones might interfere with how certain medications work in the body.

Researchers exposed rats to cell phone radiation from both CDMA and WCDMA technologies (the frequencies used by older 2G and 3G networks) for 45 minutes daily over one full year. The exposure levels were set at 4 W/kg total, which is four times higher than current safety limits. While most health measures remained normal, the study found some changes in blood chemistry and blood cell counts, though no increase in tumors or overall illness.

German researchers equipped over 3,000 children and teens with personal radiation meters for 24 hours to measure their actual exposure to radiofrequency electromagnetic fields from cell phones and other wireless devices. They then looked for connections between measured exposure levels and chronic symptoms like fatigue and headaches. The study found no statistically significant link between RF exposure and health complaints, with all measured exposure levels falling far below international safety guidelines.

Researchers tested the hearing of 125 long-term mobile phone users (both GSM and CDMA networks) against 58 people who had never used mobile phones. They found that phone users had significantly more hearing damage in their inner ears and auditory processing centers in the brain, with the damage affecting both ears and worsening after three years of use.
Baliatsas C et al. · 2011
Dutch researchers studied 3,611 adults living near cell towers and power lines to understand what causes non-specific physical symptoms like headaches and fatigue. They found that people's belief about how close they lived to these sources predicted symptoms better than the actual measured distance. The study suggests psychological factors and perceived risk may play a larger role in these health complaints than the electromagnetic fields themselves.
Panda NK, Modi R, Munjal S, Virk RS. · 2011
Researchers tested the hearing of 125 long-term mobile phone users and compared them to 58 people who never used mobile phones. They found that both GSM and CDMA phone users had significantly more hearing damage, including problems with the inner ear (cochlea) and brain's auditory processing centers. The damage was worse in people who used phones for more than 3 years and affected both ears equally.

Researchers exposed adult rats to 50-Hz magnetic fields (the same frequency as power lines) for either 1 or 4 hours daily over 4 weeks. They found that rats exposed for 4 hours showed increased anxiety-like behaviors but also improved spatial learning and long-term memory. This suggests that extremely low frequency magnetic fields can affect both emotional and cognitive brain functions, even at relatively short daily exposure periods.

Researchers exposed adult rats to 50 Hz magnetic fields (the same frequency as power lines) for either 1 or 4 hours daily over 4 weeks. Rats exposed for 4 hours showed increased anxiety-like behaviors but surprisingly improved spatial learning and long-term memory. This suggests that chronic exposure to power frequency magnetic fields can alter brain function in complex ways, affecting both emotional and cognitive processes.

Researchers studied 112 long-term mobile phone users and 50 non-users to see if cell phone radiation affects hearing. While they found no statistically significant differences between the groups, they observed concerning trends: users showed more high-frequency hearing loss and inner ear damage that worsened with longer phone use and in people over 30. The study suggests intensive mobile phone use may gradually damage the inner ear.
Panda NK, Jain R, Bakshi J, Munjal S. · 2010
Researchers compared hearing tests in 112 long-term mobile phone users versus 50 non-users. While overall differences weren't significant, phone users showed more high-frequency hearing loss and inner ear damage that worsened with longer use, suggesting phones may gradually harm hearing.
Bartsch H et al. · 2010
German researchers exposed female rats to cell phone radiation (900 MHz) throughout their lives. Exposed rats lived 9% shorter lives than unexposed rats - about 72-77 fewer days. The radiation levels matched typical cell phone exposure, suggesting chronic use might affect human lifespan.
