There have been a number of controversial reports available that provide link between cell phone use and its harmful effect on your brain. Cell phone industry continues to claim that their products are safe; there is still no scientific data available to prove this. A recent study published in the Journal of the American Medical Association, considered the most prominent, to offer scientific evidence that cell phones affect brain metabolism. The study was conducted by the National Institutes of Health.
About the Study
Researchers followed 47 participants who underwent two brain scans. During the study, cell phones were placed next to both ears while the participants underwent brain imaging using positron emission tomography (PET scans). Participants were given an injection of glucose to measure brain activity; brain cells use glucose as a source of energy.
During one scan, a cell phone connected to a muted call was attached to participants’ right ear; during the other, they were with turned off phone. Neither the participants nor the researchers knew when the cell phones were off or on.
When the phone was turned on, glucose metabolism in the section of the brain nearest the antenna was about 7% higher than when the phone was off.
“This study shows thatthe human brain is sensitive to this electromagnetic radiation,” said Dr. Nora Volkow, a...
director with the National Institutes of Health and lead researcher for the study. “Whether this electromagnetic radiation has any negative consequences, that is something that needs to be properly evaluated.”
In essence, cell phone is like a radio. When you talk on your cell phone, your voice is transmitted from the antenna as radio frequency radiation (RFR). Depending on how close the cell phone antenna is to your head, between 20% and 60% of the radiation emitted by your cell phone is transferred into your head.
Well! Phone is the one of the basic necessity of human life. The best way to avoid these radiations is to have a cell phone that can work on speakerphone. Doing so, you can greatly decrease your exposure to harmful radio frequencies (RF).
