I'm not going to try to persuade anybody one way or the other about whether or not things that we all take for granted every day might be causing some pretty frightening health situations.  There are people who are very willing to take the government's word on the safety of any given device or technique or treatment.  And there are others who suspect a great many things about a great many people - including government officials. 

So, whatever your bent may be, I'll simply refer you to an interesting piece of data that was assembled by the Environmental Working Group on the radiation emission levels of various cell phone models.  If this is something that concerns you, you might want to check it out.  If it's not something that concerns you, it still might prove a thought-provoking read.
