Devra Davis, an epidemiologist(皮膚病專家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation（輻射）"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase in brain cancer in the 20-to-29 age group and a drop for the older people.

Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（電波頻率）radiation had destroyed DNA in their brains.

Ms. Davis recommends using wired earphones（有線耳機）or the phone's speaker. (2)Children should send text messages rather than call, she said, and pregnant（懷孕的） women should keep phones away from their bodies.
