How To: Reduce phone radiation from cell phones

This "radiation" he's talking about is electro-magnetic radiation if I'm not mistaken, which is also everywhere. It comes out of your speakers when you play music, it is the radio waves that carry music to your radio, even electric motors and computers that don't have proper casing radiate this stuff. The only difference with the cell phone is that you're holding the source to your face, but I am seriously skeptical that it's any more dangerous than any other piece of technology we use nowadays.
