WARNING: Holding a cellphone against your ear or storing it in your pocket may be dangerous to your health.
This paraphrases (解释) a warning that cellphone manufacturers include in the small print that is often taken for granted when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters. Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cellphone use, the results are serious. Voice calls—Americans chat on cellphones 2.26 trillion minutes annually—bring in $109 billion for the wireless carriers.
Devra Davis, who has worked for the University of Pittsburgh, has published a book about cellphone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cellphones arrived. But the average covers an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable (易受伤害的) to radiation than adults, Ms. Davis and other scientists point out. Radiation that enters the brain of an adult only five centimeters will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cellphone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should send text message rather than call, she said, and pregnant women should keep phones away from the abdomen (腹部).
