(NaturalNews) A new study published in the
Journal of the American Medical Association has found that the radio frequency waves emitted from mobile phones demonstrably alter brain wave activity. The findings lend credence to previous studies that have suggested long-term use of such devices may be implicated in causing brain cancer.
Researchers from the U.S. National Institutes of Health (NIH) evaluated the effects of mobile phone radiation on the brains of 47 health adults. The team placed active phones on both the left and right ears of participants for 50 minutes, while simultaneously taking PET scans to measure
brain activity. They found that in the areas of
the brain closest to the phone antennas, glucose
metabolism increased by seven percent.
"What we showed is
glucose metabolism (a sign of
brain activity) increases in the brain in people who were exposed to a
cell phone in the area closest to the antenna," said Dr. Nora Volkow of
NIH, one of the study authors. "What the study does is show the human brain is sensitive to electromagnetic
radiation from cell phone exposures."
The researchers were quick to deny any link between the increased brain activity and the propensity towards cancer, but the
findings do show that such radiation does, indeed, affect the brain. Like many other
studies of this nature, the team suggests that further research be conducted to verify indicators suggesting long-term damage caused by
cell phone use.
A 2007 Finnish study published in the
International Journal of Cancer did, however, find a link between cell phone use and
cancer. Depending on the rate and duration of use, cell phone radiation was shown to be responsible for an up to 270 percent increase in gliomas, a type of brain tumor (
