Cell phone "brain rays"

Microwave radiation from your cell phone penetrates your brain

Everywhere I look, the news is abuzz with reports of Dr. Sanjay Gupta and his wired “ear bud.” Dr. Gupta will not use his cell phone without the wired ear bud attached. He’s not taking any chances with microwave radiation penetrating his brain.

Is Dr. Gupta being too careful? I don’t think so. In a 2003 Swedish study, Professor Leif Salford linked radiation from mobile phone handsets to damage to the parts of the brain associated with learning, memory and movement. Professor Salford further suggested this may trigger Alzheimer’s symptoms.

In the study, researchers studied rats aged 12-26 weeks, because their brains are believed to be in the same stage of development as teenagers, who are some of the heaviest users of cell phones.

Rats brains are similar to the human brain. They have the same blood-brain barrier and neurons. Researchers exposed the rats to two hours of radiation equivalent to 50 days of heavy mobile phone usage. Upon examination, the researchers found an abundance of dead brain cells in the rats that had been exposed to medium and high levels of radiation.

“We have good reason to believe that what happens in rats’ brains also happens in humans,” Dr. Salford said. There is a chance that exposure to mobile phone radiation could trigger Alzheimer’s Disease in some people, he added. “What we are saying is those neurons that are already prone to Alzheimer’s Disease may be stimulated earlier in life…we cannot exclude that after some decades of often daily use, a whole generation of users may suffer negative effects in their middle age.”
