Mobile phones for kids raise concerns

Researchers have speculated for more than 10 years that the electromagnetic radiation emitted from cell phones may damage DNA and cause benign brain tumors, said Henry Lai, a bioengineering professor at the University of Washington.
...Several research studies have pointed to the potential impacts of long-term absorption of cell phone-emitted radiation but little of the research has focused on the children.
Lai said he was concerned about the impact on children because young skulls are thinner and the growing brain may be more susceptible to radiation.
He also said that because brain tumors usually take 30-40 years to develop, children who use cell phones from their teen years onward would have a longer period of time to see a cumulative impact.
