I found a few videos that talk about the dangers of cell phone radiation and how we can protect ourselves. It is pretty eye-opening to see how dangerous cell phones are appearing to be.
Since I started looking into this, I have begun using a corded land-line as much as possible, and have tried to use my cell phone a whole lot less. And when I do use it, I turn the speaker all the way up and hold it at a distance, or just use the speakerphone.
CNET has a great list of cell phones that emit the most and least radiation. You can also look up your particular phone to see how much radiation it emits.
