Researchers exposed yeast cells to both 50 Hz magnetic fields and 1800 MHz radiofrequency radiation to see if electromagnetic fields could change gene activity. They found that magnetic fields caused no confirmed gene changes, while radiofrequency exposure affected only 2-5 genes out of thousands tested. This suggests that EMF effects on basic cellular processes may be more limited than some studies indicate.

Japanese researchers exposed human brain cells (glial cells) to 2.45 GHz radiofrequency radiation at various power levels for up to 24 hours and examined whether this changed gene activity. Using advanced genetic analysis techniques, they found no significant changes in how genes were expressed in the exposed cells compared to unexposed controls. This suggests that RF radiation at these levels did not trigger detectable genetic responses in this type of brain cell.
Roux D et al. · 2011
Researchers exposed human skin cells (keratinocytes) to 900 MHz radiofrequency radiation similar to cell phone signals for 10 minutes at very low power levels. They found essentially no biological effects, with only 20 out of 47,000 genes showing minor changes that weren't confirmed in follow-up testing. This suggests that brief, low-level cell phone radiation exposure may not significantly affect skin cells in laboratory conditions.

Researchers surveyed Australian schools and found that while all schools banned cellphones in class, 43% of students admitted to breaking this rule. Students who used phones at school were also more likely to carry them switched on for over 10 hours daily and keep them in their pockets. The researchers reviewed fertility studies and concluded there's enough evidence of reproductive harm to warrant removing phones from students during the entire school day.
Bourthoumieu S et al. · 2011
Researchers exposed human cells to GSM-900 MHz cell phone radiation for 24 hours at various power levels to see if it caused aneuploidy (abnormal chromosome numbers that can lead to genetic disorders). They found no significant changes in chromosome structure even at the highest exposure level of 4 W/kg. This suggests that cell phone radiation at these levels does not cause this particular type of genetic damage in laboratory conditions.
Sakurai T et al. · 2011
Researchers exposed human brain cells (glial cells) to 2.45 GHz radiofrequency radiation at power levels up to 10 times higher than current safety limits for up to 24 hours. They used advanced genetic analysis to look for changes in how genes were expressed, but found no significant alterations. This suggests that even at high exposure levels, this type of RF radiation may not directly damage the genetic machinery of brain cells.
Esmekaya MA et al. · 2011
Turkish researchers exposed human blood cells to 1.8GHz cell phone radiation for up to 48 hours and found significant genetic damage, including broken chromosomes and destroyed cell structures. However, when cells were pre-treated with Ginkgo biloba extract, much of this damage was prevented. The study suggests that cell phone radiation can harm our DNA, but natural antioxidants might offer some protection.
Chaturvedi CM et al. · 2011
Researchers exposed mice to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) for 2 hours daily over 30 days. The exposed mice showed disrupted sleep patterns, increased blood cell counts, DNA damage in brain cells, and impaired spatial memory compared to unexposed mice. This study suggests that chronic exposure to common wireless frequencies may affect brain function and biological rhythms.
Garaj-Vrhovac V et al. · 2011
Croatian researchers studied marine radar operators exposed to microwave radiation and found significant DNA damage and cellular stress compared to unexposed workers. The exposed group showed doubled genetic damage markers and clear oxidative stress, providing evidence that occupational microwave exposure causes measurable harm to human cells.
Sannino A et al. · 2011
Researchers exposed human immune cells (lymphocytes) to cell phone radiation at 1.25 W/kg for 20 hours, then tested how well the cells could protect themselves against a cancer-causing chemical. They found that cells exposed during their DNA-copying phase developed better defenses, while cells exposed during resting phases did not. This suggests that cell phone radiation may trigger protective responses in immune cells, but only when cells are actively dividing.

Researchers exposed human immune cells (lymphocytes) to electromagnetic fields from clinical 3 Tesla MRI scanners for different time periods, from 22 to 89 minutes. They found that longer exposures caused increasing levels of DNA damage, including single-strand breaks and chromosome abnormalities. This suggests that the powerful electromagnetic fields used in high-strength MRI machines may pose genetic risks that increase with exposure time.
Esmekaya MA et al. · 2011
Researchers exposed human immune cells to 1.8GHz cell phone radiation for up to 48 hours and found significant DNA damage and cellular destruction that worsened over time. Ginkgo biloba extract provided some protection, suggesting certain antioxidants might help reduce radiation-induced genetic damage in immune cells.
Trosić I et al. · 2011
Researchers exposed rats to cell phone radiation at 915 MHz for one hour daily over two weeks and examined DNA damage in brain, liver, and kidney cells using a comet assay test. They found measurable DNA breaks in liver and kidney cells, with less pronounced effects in brain cells. This suggests that radiofrequency radiation at levels similar to cell phone emissions can cause genetic damage in multiple organs.
Amara S et al. · 2011
Scientists exposed rats to static magnetic fields for 30 days, both alone and with cadmium toxin. Magnetic field exposure worsened cadmium's harmful brain effects, increasing cellular damage and reducing protective antioxidants. This suggests magnetic fields may make brains more vulnerable to environmental toxins.
Calabrò E, Condello S, Magazù S, Ientile, R. · 2011
Italian researchers exposed human brain cells to 50 Hz magnetic fields (like power lines) for three hours and found cellular damage including membrane changes, potential DNA harm, and protein breakdown indicating cell death, providing evidence that power-frequency fields can damage neural cells.
Trosić I et al. · 2011
Researchers exposed rats to cell phone radiation (915 MHz) for one hour daily over two weeks. DNA damage was found in liver and kidney cells using comet assay testing. This suggests short-term radiofrequency exposure at cell phone levels can cause genetic damage in organs.
Trosić I et al. · 2011
Researchers exposed rats to cell phone radiation (915 MHz) for one hour daily over two weeks and measured DNA damage in brain, liver, and kidney cells using the comet assay. They found measurable DNA breaks in liver and kidney cells, with slight increases in brain cells compared to unexposed control animals. This suggests that repeated exposure to cell phone-type radiation can cause genetic damage at the cellular level.

Researchers examined blood samples from people living near cell phone towers to look for genetic damage markers (micronucleus frequency and chromosomal aberrations) that could indicate cancer risk. They found no statistically significant differences between people living near towers and control groups. The study concluded that cell phone base stations do not produce important cancer-causing genetic changes.
Takeda H et al. · 2010
Researchers exposed three types of human cells to 2.1 GHz radiofrequency radiation (similar to 3G cell phone signals) for up to 96 hours at various power levels. They found no significant effects on cell growth, survival, or gene activity compared to unexposed cells. The study suggests that RF exposure at levels within current safety guidelines doesn't cause immediate cellular stress or damage.
Sekijima M et al. · 2010
Japanese researchers exposed human brain cells and lung cells to 2.1 GHz radiofrequency radiation (similar to 3G cell phones) for up to 96 hours at various power levels. They found no significant changes in cell growth, survival, or gene expression patterns compared to unexposed cells. The study suggests that RF exposure within current safety guidelines doesn't trigger obvious cellular stress responses in laboratory conditions.
Hintzsche H, Stopper H. · 2010
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.

Turkish researchers exposed rats to 1800 MHz cell phone radiation (the same frequency used by GSM networks) for 20 minutes daily over a month to test for DNA damage in bladder cells. They found no increase in micronuclei (cellular markers of genetic damage) compared to unexposed control rats. This suggests that short-term exposure to GSM radiation at these levels did not cause detectable genetic damage to bladder 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.
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.
