Cognitive impairment in rats after long-term exposure to GSM-900 mobile phone radiation.

Nittby H et al. · 2008

Swedish researchers exposed rats to cell phone radiation (GSM-900) for 2 hours weekly over more than a year, using power levels similar to what your phone emits. The exposed rats showed significantly impaired memory, specifically struggling to remember objects and when they encountered them compared to unexposed control rats. This suggests that chronic low-level cell phone radiation exposure may affect cognitive function and memory formation.

Blood-brain barrier permeability and nerve cell damage in rat brain 14 and 28 days after exposure to microwaves from GSM mobile phones

Eberhardt JL, Persson BR, Brun AE, Salford LG, Malmgren LO · 2008

Swedish researchers exposed rats to cell phone radiation at levels similar to what users experience and found it damaged the blood-brain barrier (the protective shield around the brain) and harmed brain cells. The damage appeared at very low exposure levels and persisted for weeks after exposure ended. This suggests that regular cell phone use could potentially compromise brain protection and cause neurological damage over time.

Blood-brain barrier permeability and nerve cell damage in rat brain 14 and 28 days after exposure to microwaves from GSM mobile phones.

Eberhardt JL, Persson BR, Brun AE, Salford LG, Malmgren LO. · 2008

Swedish researchers exposed rats to cell phone radiation at 900 MHz for 2 hours and examined their brains 14 and 28 days later. They found that the radiation compromised the blood-brain barrier (the protective shield around the brain) and caused nerve cell damage. The blood-brain barrier leaked proteins into brain tissue within 14 days, while actual nerve cell death appeared after 28 days.

Radiofrequency electromagnetic fields (UMTS, 1,950 MHz) induce genotoxic effects in vitro in human fibroblasts but not in lymphocytes.

Schwarz C et al. · 2008

German researchers exposed human cells to cell phone radiation (UMTS, 1,950 MHz) at levels well below safety limits to test for DNA damage. They found that skin cells (fibroblasts) showed significant genetic damage at extremely low exposure levels - as little as 0.05 W/kg, which is 40 times lower than the current safety limit. However, immune cells (lymphocytes) showed no damage, suggesting different cell types respond differently to radiofrequency radiation.

Radiofrequency electromagnetic fields (UMTS, 1,950 MHz) induce genotoxic effects in vitro in human fibroblasts but not in lymphocytes.

Schwarz C et al. · 2008

Researchers exposed human cells to 3G mobile phone radiation (UMTS at 1,950 MHz) at levels well below safety limits to test for DNA damage. They found that certain cells called fibroblasts showed significant genetic damage after exposure, while immune cells called lymphocytes were unaffected. This suggests that 3G radiation can cause DNA damage in some human cell types even at supposedly safe exposure levels.

Proportion-corrected scaled voxel models for Japanese children and their application to the numerical dosimetry of specific absorption rate for frequencies from 30 MHz to 3 GHz

Nagaoka T, Kunieda E, Watanabe S · 2008

Japanese scientists created computer models of children's bodies to study how radiofrequency radiation from cell phones and WiFi affects kids differently than adults. They found children's smaller size and body proportions change how much electromagnetic energy they absorb, highlighting potential increased vulnerability.

The effect of mobile phone electromagnetic fields on the alpha rhythm of human electroencephalogram.

Croft RJ et al. · 2008

Researchers measured brain waves in 120 people while they used mobile phones for 30 minutes, finding that phone radiation significantly changed the brain's electrical activity patterns. Specifically, the phones increased "alpha waves" (brain rhythms associated with relaxed awareness) more on the side of the head closest to the phone. This study confirms that mobile phone radiation can alter normal brain function in real-time.

Reproductive HealthNo Effects Found

Mobile phone exposure does not induce apoptosis on spermatogenesis in rats.

Dasdag S, Akdag MZ, Ulukaya E, Uzunlar AK, Yegin D. · 2008

Researchers exposed male rats to 900 MHz cell phone radiation for 2 hours daily over 10 months to see if it would trigger cell death (apoptosis) in sperm-producing cells. They found no significant increase in cell death markers in the testes of exposed rats compared to unexposed controls. This suggests that this level of cell phone radiation exposure may not directly damage sperm production through cell death pathways.

High frequency (900 MHz) low amplitude (5 V m-1) electromagnetic field: a genuine environmental stimulus that affects transcription, translation, calcium and energy charge in tomato.

Roux D et al. · 2008

French researchers exposed tomato plants to 900 MHz electromagnetic fields (the same frequency used by cell phones) at low power levels for just 10 minutes. The plants immediately activated stress response genes and began producing proteins typically associated with injury or environmental damage. The study demonstrates that even brief, low-level radiofrequency exposure can trigger biological stress responses in living organisms.

Non-thermal effects in the microwave induced unfolding of proteins observed by chaperone binding.

George DF, Bilek MM, McKenzie DR. · 2008

Researchers exposed proteins to 2,450 MHz microwave radiation (the same frequency used in microwave ovens and WiFi) and compared the results to regular heat exposure at the same temperature. They found that microwave radiation caused significantly more protein damage and unfolding than conventional heating, even when both reached identical final temperatures. This suggests that microwaves affect biological molecules through mechanisms beyond simple heating.

Proliferation, oxidative stress and cell death in cells exposed to 872 MHz radiofrequency radiation and oxidants. Radiat.

Höytö A, Luukkonen J, Juutilainen J, Naarala J. · 2008

Researchers exposed human brain cells and mouse cells to cell phone-like radiation at 5 W/kg (10 times higher than typical phone use) for up to 24 hours. The radiation alone caused no harmful effects, but when cells were already stressed by chemical toxins, the radiation made some cellular damage worse. This suggests radiofrequency radiation might amplify harm in cells that are already under stress from other sources.

A 60-Hz sinusoidal magnetic field induces apoptosis of prostate cancer cells through reactive oxygen species.

Koh EK, Ryu BK, Jeong DY, Bang IS, Nam MH, Chae KS · 2008

Researchers exposed prostate cancer cells to 60-Hz magnetic fields (the frequency of household electricity) and found the fields killed cancer cells by increasing harmful molecules called reactive oxygen species. This suggests power-line frequency magnetic fields might potentially be developed as cancer treatments.

Influence of Electromagnetic Fields Emitted by GSM-900 Cellular Telephones on the Circadian Patterns of Gonadal, Adrenal and Pituitary Hormones in Men.

Djeridane Y, Touitou Y, de Seze R. · 2008

French researchers exposed 20 healthy men to 900 MHz cell phone radiation for 2 hours daily over 4 weeks and measured their hormone levels around the clock. They found temporary decreases in growth hormone (28%) and cortisol (12%) during exposure, but these changes disappeared after stopping exposure and all hormone levels stayed within normal ranges. The study suggests that typical cell phone use may cause minor, reversible changes to certain hormones but doesn't disrupt the body's overall hormone system.

Effects of weak mobile phone - electromagnetic fields (GSM, UMTS) on event related potentials and cognitive functions.

Kleinlogel H et al. · 2008

Researchers tested whether cell phone radiation from GSM and UMTS networks affects brain activity and cognitive performance in 15 healthy adults. They measured brain waves and reaction times during various mental tasks while participants were exposed to phone radiation at levels typical of actual phone use. The study found no significant changes in brain activity or cognitive function during EMF exposure compared to fake (sham) exposure.

Histopathological examinations of rat brains after long-term exposure to GSM-900 mobile phone radiation.

Grafström G et al. · 2008

Swedish researchers exposed rats to GSM-900 cell phone radiation once weekly for over a year at power levels similar to what humans experience during phone calls. When they examined the rats' brains afterward, they found no signs of damage including blood-brain barrier leakage, cell death, or aging-related changes. This suggests that intermittent cell phone radiation exposure at typical usage levels may not cause detectable brain tissue damage.

Intercomparison of whole-body averaged SAR in European and Japanese voxel phantoms.

Dimbylow PJ, Hirata A, Nagaoka T. · 2008

Researchers compared how different computer models of human bodies absorb electromagnetic radiation (SAR) when exposed to frequencies from 30 MHz to 3 GHz. They found that European and Japanese body models showed different absorption patterns, with variations depending on how tissue properties like skin and fat were defined in the calculations. These differences matter because SAR calculations are used to set safety limits for devices like cell phones.

Reproductive HealthNo Effects Found

In vitro effect of pulsed 900 MHz GSM radiation on mitochondrial membrane potential and motility of human spermatozoa.

Falzone N et al. · 2008

Researchers exposed human sperm samples to cell phone radiation at two different intensities to see if it affected sperm health and movement. They found no effects at the lower intensity (similar to normal phone use), but at the higher intensity, sperm swimming patterns became impaired over time. This suggests that stronger EMF exposures may harm male fertility, though typical phone use levels showed no immediate damage.

Evaluation of genotoxic effects in human leukocytes after in vitro exposure to 1950 MHz UMTS radiofrequency field.

Zeni O et al. · 2008

Researchers exposed white blood cells from six healthy people to 3G cell phone radiation (1950 MHz UMTS) at levels similar to those from phones held against the head (2.2 W/kg SAR). They used intermittent exposures over 24 to 68 hours and tested for DNA damage using two sensitive laboratory methods. The study found no evidence of genetic damage or changes in how cells divide and grow.

Brain & Nervous SystemNo Effects Found

Effects of weak mobile phone - electromagnetic fields (GSM, UMTS) on well-being and resting EEG.

Kleinlogel H et al. · 2008

Swiss researchers exposed 15 healthy adults to mobile phone signals from both older GSM phones (900 MHz) and newer UMTS phones (1950 MHz) for 30 minutes to see if the radiation affected brain activity or how people felt. Using brain wave monitoring (EEG) and self-reported wellness measures, they found no significant changes compared to fake exposure sessions. This suggests that typical mobile phone radiation levels don't immediately alter brain function or cause noticeable symptoms in healthy users.

Brain & Nervous SystemNo Effects Found

Effects of weak mobile Phone-Electromagnetic fields (GSM, UMTS) on well-being and resting EEG.

Kleinlogel H et al. · 2008

Researchers exposed 15 healthy adults to electromagnetic fields from both GSM (2G) and UMTS (3G) mobile phones while measuring their brain activity with EEG and asking about their well-being. They found no significant changes in brain wave patterns or reported symptoms compared to fake (sham) exposure. The study suggests that typical mobile phone radiation levels don't produce detectable immediate effects on brain activity in healthy users.

Effect of low frequency modulated microwave exposure on human EEG: individual sensitivity.

Hinrikus H, Bachmann M, Lass J, Karai D, Tuulik V. · 2008

Researchers exposed 66 healthy volunteers to low-level microwave radiation at various frequencies and measured their brain activity using EEG. They found that microwave exposure increased brain energy levels, with 13-31% of subjects showing significant changes in their brain wave patterns depending on the frequency used. The study demonstrates that microwave radiation can alter normal brain function even at exposure levels considered safe by current standards.
