Researchers studied the relationship between cordless phone and mobile phone use among 317 Australian teenagers. They found that students who used mobile phones frequently also tended to use cordless phones frequently, creating a strong correlation between the two types of radiofrequency exposure. This matters because most health studies only measure mobile phone exposure while ignoring cordless phones, potentially underestimating people's total RF radiation exposure.

Researchers exposed 73 healthy adults to 3G cell phone radiation (UMTS) at 1.75 W/kg SAR for 20 minutes and tested their hearing function before and after exposure. They found no measurable effects on hearing thresholds, inner ear function, or brain responses to sound. This suggests that short-term exposure to 3G radiation at levels similar to heavy phone use doesn't immediately damage the auditory system.

Researchers tested whether 30 minutes of mobile phone exposure affects eye movement control, specifically the brain's ability to suppress unwanted eye movements (called saccades). They found no significant effects on this type of brain function after exposure. Both real phone exposure and fake exposure produced similar small changes in eye movement patterns, suggesting the changes were unrelated to the electromagnetic fields.

Researchers exposed human blood vessel cells (endothelial cells) to cell phone radiation at 1800 MHz for one hour at levels similar to what phones emit during calls. They used advanced protein analysis to detect any changes in how the cells functioned. The study found no statistically significant changes in protein expression, suggesting this type of radiation exposure didn't alter cellular activity in these particular cells under these conditions.

Swiss researchers studied 1,375 people in Basel to see if everyday radiofrequency radiation from cell towers, mobile phones, and cordless phones affected their sleep quality. They found no connection between RF exposure levels and sleep problems or daytime sleepiness, even among the 10% most exposed participants. This large population study suggests that typical environmental RF exposure doesn't impair sleep quality.
Mohler E et al. · 2010
Swiss researchers studied 1,375 people to see if everyday exposure to radiofrequency electromagnetic fields (RF EMFs) from cell towers, mobile phones, and cordless phones affected their sleep quality. They found no association between RF EMF exposure and sleep disturbances or daytime sleepiness, even among the 10% most exposed participants. This large population study suggests that typical environmental RF EMF exposure doesn't impair sleep quality.
Lu ST et al. · 2010
Researchers exposed four rhesus monkeys to intense 2.8 GHz microwave radiation for 36 hours total over three weeks and measured any damage to the corneal endothelium (the inner layer of cells in the eye's cornea). The study found no changes in corneal cell density or thickness, even at power levels more than ten times higher than previous studies that reported eye damage. This suggests that microwave exposure at these levels may not harm this specific part of the eye.

Researchers tested whether cell phone radiation affects children's brain processing of sounds by placing GSM phones emitting 902 MHz signals next to 17 children's heads for 12 minutes while measuring brain activity. They found no statistically significant changes in the children's auditory processing abilities during exposure. However, the study was only large enough to detect major effects, meaning smaller impacts could have been missed.

Researchers tested whether cell phone radiation affects how the brain processes sound by measuring auditory brainstem responses (electrical signals that travel from the ear to the brain) in 17 young adults exposed to GSM phone emissions. They found no differences in these brain signals whether the phone was on or off, suggesting that short-term cell phone radiation doesn't disrupt the basic pathway that carries sound information from the ear to the brain.
Kowalczuk C et al. · 2010
Researchers tested whether living cells and tissues can act like radio receivers that convert cell phone frequency signals (883 MHz) into other frequencies. They exposed over 500 samples of human and animal cells and tissues to radiofrequency energy and looked for signs that the biological material was converting the signal. No consistent signal conversion was detected, indicating that living tissue does not demodulate RF energy the way electronic devices do.
Kim KB et al. · 2010
Researchers exposed breast cancer cells (MCF7) to cell phone radiation at 849 MHz for one hour daily over three days, then analyzed whether the radiation changed protein production in the cells. They found no significant or consistent changes in protein expression at either exposure level tested (2 or 10 W/kg SAR). This suggests that radiofrequency radiation at these levels does not alter how cells make proteins, which is important because protein changes can indicate cellular stress or damage.

Researchers studied brain tumor risk in over 5,000 people across 13 countries, comparing mobile phone users to non-users. They found no overall increased risk of brain tumors from mobile phone use, but did see a 40% higher risk of glioma (a type of brain cancer) in the heaviest users who reported over 1,640 hours of cumulative call time. However, the researchers noted that recall bias and other methodological issues prevent drawing firm conclusions about causation.

Researchers analyzed 15 years of brain cancer data from the SEER cancer registry (1992-2006) to see if rising cell phone use correlated with increased brain tumors. They found no overall increase in brain cancer rates during this period of explosive cell phone adoption, and importantly, no increases in the specific brain regions (temporal and parietal lobes) that would receive the highest radiation exposure from phones held to the ear. The one exception was frontal lobe cancers in young women, but this increase began before widespread cell phone use and occurred in brain areas with lower phone radiation exposure.

Researchers examined cells from the inside of the mouth (buccal mucosa) in 131 people to see if mobile phone use causes DNA damage by looking for micronuclei, which are fragments that indicate genetic harm. They compared non-users, light users (3 hours per week or less), and heavier users (more than 3 hours weekly) and found no significant increase in DNA damage markers. This suggests that typical mobile phone use may not cause detectable genetic damage in mouth cells.

Researchers exposed human sperm samples to mobile phone radiation at levels of 2.0 and 5.7 W/kg to see if the radiation would trigger cell death (apoptosis) through several biological pathways. They found no statistically significant effects on any of the markers they tested, including DNA damage, oxidative stress, or cellular death signals. This suggests that if mobile phone radiation does harm male fertility as some studies indicate, it's likely through mechanisms other than directly killing sperm cells.

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.
Bourthoumieu S et al. · 2010
Researchers exposed human cells to GSM-900 MHz radiation (the type used by 2G mobile phones) for 24 hours to see if it caused genetic damage. Using advanced chromosome analysis techniques, they found no evidence of DNA damage or chromosomal changes at a specific absorption rate of 0.25 W/kg. This study adds to the scientific debate about whether cell phone radiation can harm our genetic material.
Luukkonen J, Juutilainen J, Naarala J. · 2010
Researchers exposed human brain cells to 872 MHz radiation (similar to older cell phone signals) at high levels for up to 3 hours, looking for DNA damage and cellular stress. They found no effects from the radiation exposure, even when combined with iron chloride, a chemical known to cause cellular damage. This suggests that at these specific conditions, the radiofrequency radiation did not harm the brain cells or their DNA.
Thomas S et al. · 2010
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.
Okano T et al. · 2010
Researchers tested whether 30 minutes of mobile phone radiation affects eye movement control, specifically the brain's ability to inhibit unwanted eye movements (saccades). They found no significant effects on inhibitory control - the changes they observed happened equally whether phones were on or off, indicating they were not caused by the electromagnetic fields. This suggests short-term mobile phone exposure doesn't impair this particular brain function.
Nylund R, Kuster N, Leszczynski D · 2010
Researchers exposed two types of human blood vessel cells to 1800 MHz cell phone radiation at levels similar to phone use (SAR 2.0 W/kg) for one hour and examined whether this changed protein production in the cells. They found no statistically significant changes in protein expression compared to unexposed cells. This suggests that short-term cell phone radiation exposure may not immediately alter how these particular blood vessel cells function at the molecular level.
Mohler E et al. · 2010
Swiss researchers studied whether exposure to radiofrequency EMFs from cell towers, mobile phones, and cordless phones affects sleep quality in 1,375 people from Basel. They found no association between RF EMF exposure and sleep disturbances or daytime sleepiness. This suggests that everyday RF EMF exposure at current environmental levels may not significantly impact sleep quality.
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.

Finnish researchers tested whether cell phone radiation affects hearing by measuring brain responses to sounds in 17 healthy adults. They found no changes in how the brain processed auditory signals when exposed to GSM phone emissions at 902.4 MHz. This suggests that short-term cell phone use doesn't interfere with the basic hearing pathways from the inner ear to the brainstem.

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.
