After interviewing physicists, engineers and doctors, CNN medical correspondent Elizabeth Cohen assembled a list of simple steps you can take to lower your exposure to cell phone radiation:

Use the speakerphone

This was the favorite alternative of the experts she talked to. Every inch you can get away from your body, the radiation reduces very quickly. Six inches can make a big difference.

Get a phone that emits less radiation

To look up the radiation emission for your phone, check this list on CNET.com. But be careful — there may simply be no safe level for cell phone radiation.

Use a wired headset with a ferrite bead, or a Bluetooth earpiece properly

A ferrite bead is a clip you put on the wire of a headset. The bead is designed to absorb the radiation that the wire itself emits into your ear.

A Bluetooth earpiece still emits radiation, but it’s at least 100 times less than the radiation you get when you hold a cell phone to your head. But don’t wear it when you’re not talking, because it still sends out a signal.

Even better — use a “hollow tube” earpiece

It’s just like a regular wired earpiece, except the last six inches or so is a hollow tube. There’s no wire under the plastic.
