A phone and a microwave aren't comparable. A microwave contains an extremely focused emitter.

It's the difference between staring at an LED light and a Class 3B or Class 4 laser.

That laser will burn right through your cornea but you could affix the LED directly to the surface of your eye without any measurable ill effect.

Take your phone and tape it to your head with it ringing day in and day out every second of every day. How long will you live?

Even though your proposition is outside of the scope of typical cell phone use, I would likely live just as long as I would have lived without it, given that its radiation is A) non-ionizing and B) not focused.

As an example, you could spend 14 hours a day in the sun to no ill effect, but only about two minutes with a magnifying glass focusing sun rays onto your forehead.
