Researchers exposed genetically modified mice (lacking a key protective protein called HSP70) to cell phone radiation at 849 MHz and 1763 MHz frequencies for 10 weeks to see if repeated exposure would trigger cellular stress responses. Even though these mice were more vulnerable to stress than normal mice, the radiofrequency radiation at 0.4 W/kg caused no detectable changes in cell death, cell growth, or stress protein production. This suggests that moderate levels of RF radiation may not activate cellular stress pathways even in compromised organisms.

Japanese researchers exposed mouse cells to 2.45 GHz microwave radiation (the same frequency used in microwave ovens and WiFi) for 2 hours at extremely high power levels up to 100 watts per kilogram. They found no chromosomal damage or genetic changes in the cells, even at these intense exposure levels that far exceed what humans typically experience from wireless devices.

Researchers exposed mice to radiofrequency radiation at cell phone frequencies (849 MHz and 1,763 MHz) for 19 weeks to test whether RF exposure could promote skin tumor growth in animals already treated with a cancer-causing chemical. No skin tumors developed in any of the RF-exposed groups, while 95% of mice treated with a known tumor promoter developed tumors. This suggests that RF radiation at levels similar to mobile phones does not act as a tumor promoter for skin cancer.
Hata K et al. · 2005
Japanese researchers exposed 208 rats to cell phone-like radiation at 1439 MHz for 12 hours to see if it affected melatonin production (the hormone that regulates sleep). They found no changes in melatonin or serotonin levels even at radiation levels four times stronger than typical mobile phones. However, the authors noted that longer exposure studies are still needed to fully understand potential effects.
Green AC et al. · 2005
Researchers exposed brain and heart cells to TETRA radio signals (the frequency used by emergency services) to see if it disrupted calcium levels inside the cells. Calcium is crucial for cell function, especially in neurons and heart muscle. The study found no significant changes in calcium activity at any exposure level tested, suggesting TETRA fields don't interfere with this fundamental cellular process.
Gorlitz BD et al. · 2005
Researchers exposed mice to cell phone radiation (GSM and DCS frequencies) for 2 hours daily over 1 and 6 weeks to test whether it causes DNA damage in blood cells and other tissues. They found no increase in micronuclei (tiny fragments that indicate genetic damage) in any of the cell types examined, even at radiation levels up to 33.2 mW/g. This suggests that cell phone-type radiation at these exposure levels does not cause detectable genetic damage in mice.
Galloni P et al. · 2005
Researchers exposed rats to cell phone radiation at 900 and 1800 MHz frequencies for 2 hours daily over 4 weeks to test if it damaged their inner ear function. Using sensitive hearing tests that measure the health of cochlear hair cells (the tiny structures that convert sound waves into nerve signals), they found no differences between exposed and unexposed animals. This suggests that typical cell phone radiation levels may not directly harm the delicate hearing mechanisms in the inner ear.
Galloni P et al. · 2005
Researchers exposed rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) and measured their hearing function using specialized tests that detect the health of inner ear cells. The study found no significant changes in hearing function during or after EMF exposure. This suggests that cell phone radiation at 900 MHz may not directly damage the delicate hair cells in the cochlea that are essential for hearing.

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used in WiFi routers and microwave ovens) and tested their ability to navigate a maze with limited visual landmarks. The rats showed no impairment in their spatial memory or navigation abilities after the exposure. This study was designed to replicate earlier research that had suggested microwave exposure could affect brain function.
Cosquer B, Galani R, Kuster N, Cassel JC. · 2005
Researchers exposed rats to 2.45 GHz electromagnetic fields (the same frequency used in WiFi and microwave ovens) for 45 minutes and measured their anxiety levels using a standard behavioral test called the elevated plus-maze. The EMF exposure, at levels producing a specific absorption rate of 0.6-0.9 W/kg, did not change anxiety responses compared to unexposed control rats. This finding suggests that short-term exposure to this type of radiofrequency radiation does not affect anxiety-related behaviors in rats.
Harakawa S et al. · 2005
Japanese researchers exposed rats to a 50 Hz electric field (the same frequency as power lines) for 15 minutes daily over a week to study effects on oxidative stress markers. They found that the electric field actually reduced harmful lipid peroxides in rats that were given an oxidizing agent, suggesting a protective antioxidant-like effect. However, the electric field had no effect on healthy rats that weren't under oxidative stress.

Researchers directly measured brain electrical activity in mice while exposing them to cell phone frequency electromagnetic fields. They found that healthy mice showed clear changes in brain wave patterns, with cortical activity shifting to lower frequencies and hippocampal activity increasing in higher frequencies. These real-time brain changes during EMF exposure provide direct evidence that radiofrequency radiation can alter normal brain function.

Researchers exposed cancer-prone mice to radiofrequency radiation for just one hour per week over four months and tracked their health for 18 months. The RF-exposed mice developed cancer earlier and died sooner than unexposed controls, with the radiation disrupting calcium transport in cells - a process critical for normal cell function. This suggests that even minimal RF exposure may accelerate cancer development in vulnerable populations.
Nikolova T et al. · 2005
German researchers exposed developing brain cells to both power line frequencies (50 Hz) and cell phone frequencies (1.71 GHz) for 6 hours to study genetic effects. They found that both types of electromagnetic fields triggered changes in genes that control cell death and DNA damage responses, though the cells themselves appeared to function normally afterward. This suggests that EMF exposure can activate cellular stress responses even when no obvious harm is visible.
Ozguner F et al. · 2005
Turkish researchers exposed rats to 900 MHz mobile phone radiation and found it caused kidney damage by increasing harmful molecules and reducing protective antioxidants. However, when rats were pre-treated with melatonin or CAPE (a natural compound from propolis), both substances protected against this kidney damage, with melatonin showing stronger protective effects. This suggests that mobile phone radiation can harm kidney tissue through oxidative stress, but natural antioxidants may offer protection.
Ozguner F, Oktem F, Ayata A, Koyu A, Yilmaz HR. · 2005
Researchers exposed rats to 900 MHz mobile phone radiation (the same frequency used by many cell phones) and found it caused significant kidney damage through oxidative stress - essentially, the radiation generated harmful molecules that damaged kidney tissue and reduced the kidneys' natural antioxidant defenses. When the researchers treated another group of rats with an antioxidant compound, it prevented most of this kidney damage, suggesting that cell phone radiation harms organs by overwhelming the body's ability to neutralize harmful free radicals.
Wang Q, Cao ZJ, Bai XT. · 2005
Researchers exposed developing rat brain cells to 900 MHz radiation from older cell phones for up to 12 hours. The radiation significantly disrupted GABA receptors, brain chemicals that control neural activity, suggesting cell phone frequencies can alter fundamental brain chemistry during development.
Trosic I, Busljeta I. · 2005
Researchers exposed rats to 2.45 GHz microwave radiation (WiFi frequency) for 2 hours daily. After 15 days, the radiation caused genetic damage in bone marrow cells that produce blood, increasing DNA breaks even at non-heating power levels, raising concerns about wireless device safety.
Seaman RL, Phelix CF. · 2005
Researchers exposed rats to pulsed microwave radiation at cell phone-level intensities and examined brain cell structure under a microscope. High-intensity microwaves (6 W/kg) caused visible damage to brain cell components, while lower-intensity exposure (0.6 W/kg) appeared to have protective effects against a brain toxin. The findings suggest that microwave radiation can alter brain cell structure in complex ways that depend on the exposure intensity.
Nikolova T et al. · 2005
Researchers exposed developing mouse brain cells to power line fields and cell phone radiation for up to 48 hours. Both EMF types altered genes controlling cell death and DNA repair, suggesting cells experienced stress even though they appeared to function normally afterward.
Finnie JW. · 2005
Researchers exposed mice to cell phone radiation for one hour to test if it stressed brain cells by activating a stress gene called c-fos. They found radiation didn't cause brain stress - restraining the animals during testing did, showing proper study controls matter.
Ebert S et al. · 2005
Researchers exposed mice to 905 MHz radiofrequency radiation at various power levels to determine when their bodies could no longer regulate temperature. They found that mice began struggling to maintain normal body temperature at radiation levels between 2-5 W/kg, and completely lost temperature control around 6-10 W/kg during 2-hour exposures.

Researchers exposed mice to cell phone-level radiation (900 MHz) for 12 hours daily over a week and examined sperm DNA for damage. While the mice appeared healthy and sperm counts looked normal, detailed genetic analysis revealed significant DNA damage in both the mitochondria (cellular powerhouses) and nuclear DNA of sperm cells. This suggests that radiofrequency radiation can harm genetic material in reproductive cells even when other measures appear normal.
Lai H, Singh NP · 2005
Researchers exposed rats to cell phone-frequency microwaves (2450 MHz) for 2 hours and found significant DNA damage in brain cells. However, when they simultaneously exposed the rats to a weak magnetic field with random fluctuations, it completely blocked the DNA damage from occurring. This suggests that certain types of magnetic field exposure might actually protect against some forms of EMF damage.
Wolf FI et al. · 2005
Italian researchers exposed cells to 50 Hz magnetic fields from power lines for 72 hours. The exposure increased cell growth by 30% and caused DNA damage through free radicals. Antioxidant treatment prevented these effects, suggesting household electrical fields may harm cells.
