Pediatric researchers suggest potential dangers for children from cellphone exposure
Doctors and scientists from Harvard and Yale medical schools warned Tuesday that pregnant mothers limit their unborn babies exposure to potentially harmful radiation by keeping cellphones away from their tummies because of the possible effect on brain development.
The doctors offered the advice during the Pediatric Academic Societies annual meeting in Baltimore U.S.A., where they also said parents should limit their children’s use of cellphones, iPads and other wireless technology because it can cause behavioral and concentration problems.
In one study, Dr. Hugh Taylor, chair of obstetrics, gynecology and reproductive sciences at Yale School of Medicine, put cellphones on the top of cages containing pregnant mice. He then studied the behavior of the offspring and found that they had decreased memory and were hyperactive.
Dr. Martha Herbert, with Harvard University and Massachusetts General Hospital, looked at the biological factors that can go wrong in autism and found a strong correction with the electromagnetic field of Wifi. The fields disturb calcium signaling in the brain, which is supposed to regulate the flow of information at the cell membrane going into the nucleus, she said in a phone interview after the her presentation. “It can make the brain get too excited and irritated,” Herbert said. “It is not inconceivable that it can cause (autism), but there are other factors that can play a role. It certainly can aggravate it.”
In other research, brain models and computer simulations show that children absorb 10 times more microwave radiation than adults because a child’s skull is thinner and smaller.
