Exposure to electromagnetic fields and the risk of childhood leukaemia: a review

Unknown authors · 2008

This 2008 review examined the connection between electromagnetic field exposure and childhood leukemia risk. The analysis confirmed that extremely low-frequency magnetic fields above 0.3-0.4 microT are associated with increased childhood leukemia risk, leading to their classification as possibly carcinogenic. However, no biological mechanism has been established and the association could still be due to chance or bias.

DNA and chromosomal damage in response to intermittent extremely low-frequency magnetic fields

Unknown authors · 2008

Researchers exposed human skin cells to intermittent extremely low-frequency magnetic fields (50-1000 microTesla) for 15 hours to test for DNA and chromosomal damage. Using multiple sensitive detection methods, they found no evidence of genetic damage from the magnetic field exposure, contradicting some previous studies that reported harmful effects.

Case-only study of interactions between DNA repair genes (hMLH1, APEX1, MGMT, XRCC1 and XPD) and low- frequency electromagnetic fields in childhood acute leukemia

Unknown authors · 2008

Researchers studied 123 children with acute leukemia to see if certain DNA repair gene variants interact with power line and transformer EMF exposure. They found children with a specific XRCC1 gene variant had over 4 times higher odds of leukemia when living within 100 meters of electrical infrastructure. This suggests some children may be genetically more vulnerable to low-level electromagnetic field exposure.

Childhood Leukemia in Relation to Radio Frequency Electromagnetic Fields in the Vicinity of TV and Radio Broadcast Transmitters

Unknown authors · 2008

German researchers studied 1,959 children with leukemia and 5,848 healthy controls living near TV and radio broadcast transmitters between 1984-2003. They found no increased risk of childhood leukemia from radio frequency electromagnetic field exposure, even among children living within 2 kilometers of high-power broadcast towers. The study represents one of the largest investigations into broadcast tower EMF and childhood cancer.

GSM base stations: Short-term effects on well-being

Unknown authors · 2008

This 2008 analysis reexamined data from a controversial study on electromagnetic hypersensitivity (EHS), finding that people claiming EMF sensitivity actually did show measurable physiological responses to cell tower signals. The original researchers had dismissed these responses, but this reanalysis revealed significant reactions in tension, anxiety, and skin conductance among sensitive individuals when exposed to GSM and UMTS base station signals.

Assessment of DNA sensitivity in peripheral blood leukocytes after occupational exposure to microwave radiation: the alkaline comet assay and chromatid breakage assay

Unknown authors · 2008

Researchers tested DNA damage in radar facility workers exposed to microwave radiation (1,250-1,350 MHz) and found significantly more genetic damage compared to unexposed controls. The workers showed increased DNA breaks and their cells were three times more sensitive to additional DNA damage when tested in the lab.

Biological effects from electromagnetic field exposure and public exposure standards

Unknown authors · 2008

This 2008 review examined biological effects from both power line frequencies and wireless radiation, finding evidence linking EMF exposure to childhood leukemia, brain tumors, and other health effects. The authors concluded that current safety standards ignore non-thermal effects and recommended significantly lower exposure limits. The paper specifically highlighted the BioInitiative Report's findings that reasonable suspicion of health risks exists at environmentally relevant EMF levels.

Mobile phone use, exposure to radiofrequency electromagnetic field, and brain tumour: a case-control study

Unknown authors · 2008

Japanese researchers studied 322 brain tumor patients and 683 healthy controls to examine whether mobile phone use increases brain tumor risk. They found no significant increase in brain tumor risk from mobile phone use, even when accounting for the specific absorption rate (SAR) of radiation inside tumor tissue. All exposure levels were well below thermal heating thresholds.

Elevation of plasma corticosterone levels and hippocampal glucocorticoid receptor translocation in rats: a potential mechanism for cognition impairment following chronic low-power-density microwave exposure

Unknown authors · 2008

Researchers exposed rats to 2.45 GHz microwave radiation (similar to WiFi frequency) at very low power levels for 3 hours daily over 30 days. The exposed rats showed significant learning and memory problems, along with elevated stress hormones and brain cell death in the hippocampus. When researchers blocked the stress hormone receptors, the cognitive damage was partially prevented.

Radiofrequency electromagnetic field exposure and non-specific symptoms of ill health: A systematic review

Unknown authors · 2008

This 2008 systematic review examined whether people claiming electromagnetic hypersensitivity (EHS) can actually detect radiofrequency fields from phones and base stations. The study found that people with EHS could only detect RF fields 4.2% better than random chance, with no meaningful difference from non-EHS individuals. While population studies show associations between RF exposure and symptoms, controlled laboratory tests suggest these may be psychological rather than biological effects.

Effect of superposed electromagnetic noise on DNA damage of lens epithelial cells induced by microwave radiation

Unknown authors · 2008

This retracted 2008 study examined how 1.8 GHz cell phone radiation affects DNA damage in human eye lens cells. Researchers found that higher radiation levels (3-4 W/kg) caused DNA damage and increased harmful molecules called reactive oxygen species. Interestingly, adding electromagnetic 'noise' appeared to block these damaging effects.

Analysis of time-frequency fine structure of transiently evoked otoacoustic emissions to study the effects of exposure to GSM radiofrequency fields

Unknown authors · 2008

Researchers tested whether 10 minutes of GSM mobile phone radiation affects inner ear function in 27 healthy young adults using sensitive hearing tests called TEOAEs. Both standard and advanced wavelet analysis showed no immediate changes to cochlear function after real versus fake exposure. The study found no detectable impact on the ear's ability to produce these subtle acoustic emissions.

Recall bias in the assessment of exposure to mobile phones

Unknown authors · 2008

Researchers analyzed mobile phone records from 212 brain tumor patients and 296 healthy controls to check if people accurately remember their past phone use. Both groups made similar memory errors - underestimating call frequency by 19% while overestimating call duration by 40%. This finding suggests that memory bias likely doesn't skew mobile phone health studies significantly.

Radiofrequency and extremely low-frequency electromagnetic field effects on the blood-brain barrier

Unknown authors · 2008

This 2008 review examined scientific evidence on how radiofrequency and extremely low-frequency electromagnetic fields affect the blood-brain barrier, the protective system that prevents harmful substances from entering brain tissue. The researchers found mixed results, with some studies showing EMF exposure can disrupt this crucial barrier at non-thermal levels, while others showed no effect.

Mechanism for combined action of microwaves and static magnetic field: slow non uniform rotation of charged nucleoid

Unknown authors · 2008

Researchers developed a theoretical model explaining how microwaves and static magnetic fields work together to affect DNA structure in bacterial and human cells. The model proposes that this combination causes the charged DNA core (nucleoid) to rotate slowly and unevenly, with the rotation speed depending on magnetic field properties. This provides a potential mechanism for non-thermal biological effects from microwave radiation.

Mobile phone radiation and the risk of cancer; a review

Unknown authors · 2008

Nigerian researchers reviewed decades of scientific studies examining whether mobile phone radiation causes cancer. The review found no significant increase in cancer rates among mobile phone users, even in studies following people for over ten years. However, the authors emphasized caution since cancer can take up to 40 years to develop.

Analysis of RF exposure in the head tissues of children and adults

Unknown authors · 2008

French researchers used MRI-based head models to compare RF radiation absorption in children versus adults when using cell phones at multiple frequencies (900-2400 MHz). They found that children aged 5-8 years absorbed about twice as much radiation in peripheral brain tissues compared to adults, while older children showed similar absorption levels to adults. The higher absorption in younger children was attributed to their thinner skull, skin, and ear tissue.

In vitro testing of cellular response to ultra high frequency electromagnetic field radiation

Unknown authors · 2008

Croatian researchers exposed hamster cells to 935 MHz radiation (similar to older cell phones) at very low power levels for up to 3 hours. They found that the radiation disrupted the cells' internal structure and slowed their growth for several days afterward. This suggests that even weak radiofrequency radiation can interfere with basic cellular functions.

Gene and protein expression following exposure to radiofrequency fields from mobile phones

Unknown authors · 2008

This 2008 review examined studies using advanced gene and protein screening techniques to detect cellular changes from mobile phone-level radiofrequency radiation. The analysis found that most positive results were flawed by methodological problems, and no consistent patterns of gene or protein changes could be identified. The authors concluded that current evidence doesn't support the idea that cell phone radiation acts as a cellular stressor at typical exposure levels.

Cellular EffectsNo Effects Found

Radiofrequency radiation does not significantly affect ornithine decarboxylase activity, proliferation, or caspase-3 activity of fibroblasts in different physiological conditions

Unknown authors · 2008

Finnish researchers exposed mouse fibroblast cells to 872 MHz radiofrequency radiation (similar to older cell phone frequencies) under different stress conditions to see if cell state affects EMF sensitivity. They found no consistent biological effects on cell growth, death, or key enzyme activity, even when cells were stressed or stimulated. This suggests that varying cell conditions don't explain why EMF studies sometimes produce conflicting results.

Genetic damage in subjects exposed to radiofrequency radiation

Unknown authors · 2008

This 2008 review examined cytogenetic biomonitoring studies of humans exposed to radiofrequency (RF) radiation from occupational sources or frequent use of RF-emitting devices. A majority of the reviewed studies reported increased frequencies of genetic damage such as chromosomal aberrations in lymphocytes or buccal cells of RF-exposed individuals, though the authors noted most studies had significant methodological shortcomings including lack of radiation dosimetry data.

Mobile phones and brain tumours: a review of epidemiological research

Unknown authors · 2008

Australian researchers reviewed all available epidemiological studies examining whether mobile phone use increases brain tumor risk. While some individual studies suggested weak associations between long-term phone use and certain brain tumors, the overall evidence was inconsistent and likely influenced by recall bias. The review concluded that the research does not provide convincing evidence of a link between mobile phones and brain tumors.

DNA & Genetic DamageNo Effects Found

Evaluation of HSP70 Expression and DNA Damage in Cells of a Human Trophoblast Cell Line Exposed to 1.8 GHz Amplitude-Modulated Radiofrequency Fields.

Valbonesi P et al. · 2008

Researchers exposed human placental cells to cell phone radiation (1.8 GHz GSM signals) for one hour at levels twice the current safety limit to see if it would trigger cellular stress responses or DNA damage. The radiation exposure produced no detectable effects on stress proteins or DNA integrity, unlike positive control treatments that did cause measurable damage. This suggests that short-term exposure to this type of cell phone radiation may not immediately harm these particular cells.

Immune SystemNo Effects Found

Effects of GSM-modulated radiofrequency electromagnetic fields on mouse bone marrow cells.

Prisco MG et al. · 2008

Italian researchers exposed mice to cell phone radiation (900 MHz GSM signals) for 4 weeks, then transplanted their bone marrow cells into radiation-damaged mice to test if the EMF exposure affected the immune system's ability to rebuild itself. The bone marrow cells from EMF-exposed mice performed just as well as unexposed cells in rescuing the damaged mice and rebuilding their immune systems. This suggests that moderate cell phone radiation exposure doesn't impair the bone marrow's critical immune-building functions.

Symptoms & SensitivityNo Effects Found

Can evidence change belief? Reported mobile phone sensitivity following individual feedback of an inability to discriminate active from sham signals.

Nieto-Hernandez R et al. · 2008

Researchers tested whether people claiming sensitivity to mobile phone signals could actually detect when phones were on versus off, then told participants their results to see if accurate feedback would change their symptoms. Even when told they couldn't actually detect phone signals, participants' sensitivity symptoms and beliefs remained unchanged six months later. The study suggests that providing scientific evidence alone may not be enough to help people with electromagnetic hypersensitivity reconsider their symptoms.
