Effects of 900-MHz radio frequencies on the chemotaxis of human neutrophils in vitro, IEEE Trans Biomed Eng. 2008 Feb;55(2):795-7

Unknown authors · 2008

Researchers exposed human immune cells (neutrophils) to 900-MHz RF radiation at extremely low power levels in laboratory conditions. The RF exposure increased cell movement speed by 50% compared to temperature effects alone and dramatically altered the cells' direction of movement away from their normal chemical tracking pattern. These changes occurred at power levels producing less than one-millionth of a degree of heating.

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 phone frequencies) for up to 3 hours at very low power levels. They found that 3-hour exposures damaged the cell's internal structure and significantly reduced cell growth for days afterward, suggesting that even brief, low-level exposures can disrupt normal cellular function.

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.

Mobile phone base stations and adverse health effects: Phase 1: A population-based cross-sectional study in Germany

Unknown authors · 2008

German researchers surveyed over 30,000 people about their health complaints and proximity to cell tower base stations. They found that people living within 500 meters of cell towers reported slightly more health symptoms, and this increase couldn't be fully explained by worry or concern alone. Nearly 19% of participants were concerned about health effects from nearby cell towers.

Cellular phone use and brain tumor: a meta-analysis

Unknown authors · 2008

This 2008 meta-analysis of nine case-control studies examined whether cellular phone use increases the risk of brain tumor development, analyzing data from 5,259 brain tumor cases and 12,074 controls. The pooled analysis found no overall increased brain tumor risk among cellular phone users (OR 0.90), though long-term users with ≥10 years of follow-up showed a potentially elevated risk (OR 1.25) that the authors noted requires confirmation by future studies.

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.

Effects of 900-MHz radio frequencies on the chemotaxis of human neutrophils in vitro, IEEE Trans Biomed Eng. 2008 Feb;55(2):795-7

Unknown authors · 2008

Researchers exposed human neutrophils (white blood cells) to 900-MHz radio frequency radiation at levels comparable to cell phone exposure and found their movement speed increased by 50% compared to temperature effects alone. More significantly, the cells stopped following chemical signals they normally track to fight infection, instead moving at right angles to those signals. The calculated temperature change from the RF exposure was negligible, indicating a non-thermal biological effect.

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.

Prenatal and Postnatal Exposure to Cell Phone Use

Unknown authors · 2008

Researchers tracked 13,159 children from pregnancy through age 7 and found that those exposed to cell phone use both before birth and after showed 80% higher odds of behavioral problems including hyperactivity and emotional difficulties. The Danish study suggests cell phone radiation exposure during critical developmental periods may impact children's behavior, though researchers acknowledge other factors could explain the association.

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.

Microwaves from UMTS/GSM mobile phones induce long-lasting inhibition of 53BP1/gamma-H2AX DNA repair foci in human lymphocytes

Unknown authors · 2008

This 2008 study examined whether microwave radiation from UMTS and GSM mobile phones affected DNA repair mechanisms in human lymphocytes from both healthy individuals and those reporting electromagnetic hypersensitivity. The researchers found that UMTS microwaves inhibited the formation of DNA repair foci (53BP1/gamma-H2AX) for up to 72 hours after exposure, with effects persisting longer than typical stress responses, and observed some differential responses between hypersensitive and healthy subjects depending on the signal type.

Cognitive effects of radiation emitted by cellular phones: The influence of exposure side and time

Unknown authors · 2008

Researchers tested 48 healthy men performing memory tasks while exposed to GSM cell phone radiation on either the left or right side of their heads. They found that left-side phone exposure significantly slowed reaction times for right-hand responses during the first few minutes of testing. This suggests cell phone radiation can immediately affect brain function in ways that depend on which side of your head the phone touches.

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.
