Tips to limit your cell phone risk

Cell phones do emit radiation. No one knows definitively whether it's enough to worry about.

Mobile phones meet federal safety limits, but if you're still worried, there are some simple steps you can take to lower your exposure to radiation.

Use the speakerphone. Hold it away from a minimum of a few inches, a foot or two is ideal.

Use a wired headset with a ferrite bead. The bead is designed to absorb the radiation so you don't.

Use a Bluetooth earpiece. A Bluetooth earpiece still has radiation, but it's at least 100 times less than the radiation you get when you hold a cell phone to your head.

Use a "hollow tube" earpiece. It's just like a regular wired earpiece, except the last six inches or so -- the part next to your ear -- is a hollow tube and there’s no wire under the plastic.

Get a phone with less radiation. Phone radiation is measured in specific absorption rate, or SAR.
