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 ofthe brainclosest to the phone antennas, glucosemetabolismincreased by seven percent.
“What we showed isglucosemetabolism (a sign ofbrainactivity) increases in the brain in people who were exposed to acell phonein the area closest to the antenna,” said Dr. Nora Volkow ofNIH, one of the study authors. “What the study does is show the human brain is sensitive to electromagneticradiationfrom cell phone exposures.”
The researchers were quick to deny any link between the increased brain activity and the propensity towards cancer, but thefindingsdo show that such radiation does, indeed, affect the brain. Like many otherstudiesof this nature, the team suggests that further research be conducted to verify indicators suggesting long-term damage caused bycell phone use.
A 2007 Finnish study published in theInternational Journal of Cancerdid, however, find a link between cell phone use andcancer. 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 (http://www.naturalnews.com/021634.html).
