Bluetooth Headset Danger How About Bluetooth Headset Danger?

How about Bluetooth Headset danger? - bluetooth headset danger

If you usually speak on the phone hands free Blutooth ...
The waves or radiation can damage the brain, is not it?

I'm afraid, because they talk on the phone to 2-3 hours a day ...

Maybe the Bluetooth radio waves is not the brain, or a little tampering with the device, there is no danger (I think)

Please answer me ... Thank you very much
