Determine if the Full Body Scanners are effecting the health of Americans and if they should be taken out and revised.

I would like to find out if there is harm from these body scanners not only to families but also to the workers and if they actually work. I have heard a multitude of opinions and would like to get the facts on these machines. I also think that they violate your civil liberties and should be revised to make something more effective and less evasive to the public.
