How to cut your exposure to cell-phone radiation

Q. Is it true that cell phones emit dangerous levels of radiation?

A. Possibly. Cell phones expose you to radio­frequency electromagnetic energy, a form of “non-ionizing” radiation (similar to what’s emitted from microwave ovens). Some studies have suggested that cell-phone use alters brain function and may increase the risk of some cancers, although the overall evidence hasn’t found a clear link. More study is needed to determine the health effects of cell-phone use, and what constitutes a safe level of use.

For now, you can reduce radiation exposure by:

• Limiting talk time;
• Using a speakerphone or headset;
• Holding the phone away from your ear; and
• Replacing some calls with text messaging or e-mail.
