This will probably sound like a strange question, but here goes. We all have heard about the potential health risks of use of cell phones, and that phone manufacturers recommend that you keep the phone as far away from you as possible while in use to reduce potential harmful exposure to radio waves.

What about the use of bluetooth headsets? It seems to me that these devices also receive the same radio transmissions, and being worn directly next to the brain they could potentially be even more dangerous than simply holding a cell phone to your ear.

Does anybody have any good information on this? Thanks.

Headsets and other bluetooth devices only need to broadcast 20 meters (max) or so, less than 2 KM for cellphones and PDA"s such as blackberries. As a result the batteries required are much smaller, therefore the intensity of the radio waves is greatly reduced.

It's still a worry, but your talking orders of magnitude less than that of a cellphone. Best get rid of the cellphone if you are that paranoid. =)

I'm not that paranoid. I only ask because now you get a federally mandated safety notice when you buy a cellphone, and the same is not true of bluetooth devices. I was just curious.
