Russo R et al. · 2006
Researchers tested 168 people on attention and cognitive tasks while exposed to mobile phone signals (both GSM and continuous wave) versus fake signals. They found no significant differences in performance on reaction time, vigilance, or mental math tasks regardless of which type of signal participants were exposed to or which side of the head the phone was positioned on.
Remondini D et al. · 2006
Researchers exposed six different types of human cells to mobile phone frequencies (900 and 1800 MHz) and analyzed whether the radiation changed gene activity patterns. Three cell types showed no changes, while three others had small numbers of genes (12-34) that became more or less active, particularly genes involved in protein production. The changes didn't indicate cellular stress or damage responses.
Regel SJ et al. · 2006
Swiss researchers exposed 117 people (including those who claimed sensitivity to electromagnetic fields) to cell tower-like radio frequency signals for 45 minutes at different intensities. They found no meaningful effects on well-being or cognitive performance at any exposure level, even among people who believed they were sensitive to EMF. The study contradicted earlier Dutch research that suggested cell tower exposure could affect well-being.
Radon K et al. · 2006
German researchers tested whether personal dosimeters could accurately measure people's daily exposure to cell tower radiation by having 163 participants wear monitoring devices for 24 hours. They found that people's self-reported exposure levels didn't match what the dosimeters actually measured, and two different dosimeter models showed only moderate agreement with each other (correlation of 0.35). This suggests that while personal dosimetry might be useful for research studies, the measurement tools need improvement for reliable exposure assessment.
Qutob SS et al. · 2006
Researchers exposed human brain cancer cells (glioblastoma) to 1.9 GHz radiofrequency radiation for 4 hours at power levels ranging from very low to quite high (0.1 to 10 W/kg SAR). They found no changes in gene expression at any exposure level, while heat treatment successfully triggered expected cellular stress responses. This suggests that RF fields at these levels don't alter how genes function in these particular brain cells.
Natarajan M et al. · 2006
Researchers exposed human immune cells to extremely powerful pulsed electromagnetic fields (1,000 times stronger than typical EMF exposures) for 90 minutes and found that while the fields initially activated a key cellular stress response called NF-kappaB, this activation was functionally meaningless - it didn't actually trigger the downstream immune responses that normally follow. The study suggests that even very high EMF exposures may not necessarily translate into biological consequences.
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.
Nam KC, Kim SW, Kim SC, Kim DW · 2006
Researchers exposed 42 volunteers (21 teenagers and 21 adults) to radio frequency radiation from CDMA cell phones for 30 minutes while measuring vital signs like blood pressure, heart rate, and breathing. The study found no changes in these cardiovascular measures, though skin resistance decreased temporarily in teenagers and males during exposure. This suggests that short-term cell phone use doesn't immediately affect basic vital signs, though the skin resistance change indicates the body does respond to the radiation in measurable ways.
Nagaoka T et al. · 2006
Japanese researchers created a detailed computer model of a pregnant woman and her 7-month-old fetus to study how radiofrequency radiation affects both mother and baby during whole-body exposure. This was a modeling study that developed tools for calculating radiation absorption (called SAR) in pregnant women, rather than measuring actual health effects. The research provides important groundwork for understanding how EMF exposure during pregnancy might differ from exposure in non-pregnant women.
Muscat JE, Hinsvark M, Malkin M · 2006
Researchers analyzed brain cancer rates in the United States from 1973 to 2002, comparing them to the dramatic rise in mobile phone use that began in 1984. Despite mobile phone subscriptions increasing exponentially during this period, rates of neuronal brain cancers remained unchanged. This suggests that mobile phone use does not increase the risk of these specific types of brain tumors.
Mora R, Crippa B, Mora F, Dellepiane M · 2006
Italian researchers tested whether cell phone radiation affects hearing by exposing 20 healthy men to phone signals (900-1,800 MHz) for 15-30 minutes while measuring their auditory responses. They found no changes in hearing function during or after exposure. This suggests short-term cell phone use doesn't immediately damage the auditory system.
Mjøen G et al. · 2006
Norwegian researchers studied whether fathers exposed to radiofrequency radiation at work had children with more birth defects or pregnancy complications. They analyzed data from over 100,000 births and found mixed results: fathers with the highest occupational RF exposure had an 8% increased risk of preterm birth, but actually lower rates of some birth defects like cleft lip. The researchers concluded the findings were "partly reassuring" for exposed fathers.
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.
Masuda H et al. · 2006
French researchers exposed hairless rats to cell phone radiation (GSM-900 and GSM-1800 signals) for 2 hours at high intensity levels (5 W/kg SAR) and examined their skin tissue for damage. They found no changes in skin thickness, cell death, cell growth patterns, or key skin proteins compared to unexposed animals. This suggests that acute exposure to these cell phone frequencies at high levels does not cause immediate visible damage to skin tissue.
Maby E, Jeannes Rle B, Faucon G · 2006
French researchers studied how cell phone radiation affects brain activity by measuring electrical responses to sound in 9 healthy people and 6 epilepsy patients. They found that GSM phone signals altered the timing and strength of brain waves, with different effects in healthy people versus those with epilepsy. While the changes were measurable, the researchers couldn't determine if these brain activity modifications cause actual health problems.
Lonn S et al. · 2006
Researchers in Denmark and Sweden studied whether long-term mobile phone use increases the risk of parotid gland tumors (tumors in the salivary glands near your ears). They compared 172 people with these tumors to 681 healthy controls, examining their mobile phone usage patterns over more than 10 years. The study found no increased risk of either malignant or benign parotid gland tumors associated with mobile phone use, even among long-term users.
Lee JS, Huang TQ, Kim TH, Kim JY, Kim HJ, Pack JK, Seo JS. · 2006
Researchers exposed human immune cells and rat brain cells to cell phone-level radiofrequency radiation (1763 MHz) at power levels of 2 and 20 W/kg for up to one hour while carefully controlling temperature. They found no activation of cellular stress responses, including heat shock proteins and stress-signaling pathways that typically activate when cells are damaged. This suggests that RF radiation at these levels does not trigger the cellular alarm systems that respond to harmful stressors.
Lantow M, Viergutz T, Weiss DG, Simko M. · 2006
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.
Lahkola A, Tokola K, Auvinen A. · 2006
Researchers analyzed 12 studies involving 2,780 people with brain tumors to determine if mobile phone use increases cancer risk. They found no significant increase in brain tumor risk for people who used mobile phones for more than 5 years, with odds ratios (risk measures) hovering around 1.0 for all tumor types studied. This suggests that at least for the first 5-10 years of mobile phone use, the risk of developing brain tumors does not appear to increase substantially.
Keow MA, Radiman S. · 2006
Malaysian researchers measured radiofrequency radiation levels at 200 locations around 47 cell phone base stations mounted on rooftops. They found that all measured radiation levels were well below the safety limits established by various international agencies and countries. This study was conducted to address growing public concerns about potential health risks from these increasingly common wireless infrastructure installations.
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.
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.
Hepworth SJ et al. · 2006
Researchers studied 966 glioma patients and 1,716 healthy controls to see if mobile phone use increases brain tumor risk. They found no overall increased risk of glioma from phone use, with an odds ratio of 0.94 (meaning slightly lower risk, though not statistically significant). However, they noted some curious findings about tumor location that they attributed to recall bias rather than real biological effects.
Heikkinen et al. · 2006
Finnish researchers exposed female rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for 2 hours daily over 2 years while also giving them a known cancer-causing chemical in their drinking water. The study aimed to see if RF radiation would make tumors more likely to develop. The researchers found no evidence that RF radiation increased cancer risk, even when combined with a chemical known to cause tumors.
Hamblin DL, Croft RJ, Wood AW, Stough C, Spong J. · 2006
Researchers exposed 120 people to mobile phone radiation for 30 minutes while measuring their brain activity and reaction times during cognitive tasks. They found no significant changes in brain function, reaction speed, or electrical brain patterns compared to fake exposure sessions. This contradicts some earlier studies that suggested cell phones might affect how quickly the brain processes information.
