I’m not a doctor, but I blog like I play one on TV. How’s that for a disclaimer?
The truth is I don’t know. And no one else does either. What I do know is that today’s cell phones put out less power than they ever did before, about 1/100th of those 1980s behemoths.
There is a lot of common sense involved here. We know that cell phones give off radiation. We know that radiation will hurt you. So it should follow that a cell phone next to your head should hurt you, right? Truth is, the amount of radiation given off by a cell phone is less than you would get from the sun on a bright day.
So far there is no conclusive study either way, although it seems like both sides have their own studies to back up their own points of view.
If you are worried about a cell phone cooking your brain, use a bluetooth headset. It puts out far less radiation than a cell phone. Or, use a wired headset; it puts out essentially no radiation at all.
