CRT's DO NOT emit any radiation other than visible light!  Anyone that
says otherwise is a vendor trying to use scare tactics to get you to
buy his screen filter product.  Probably the thing that some people
mistakenly think is radiation is the static electric charge on the
surface of the screen that you can feel when you bring your arm near to
the screen.

Gas plasma screens work like miniature neon lights.  The gas ionizes and
gives off light.
