In article <837@helios.toronto.edu> I write:

	I should perhaps add to this statement by saying that there is
no simple device that you could attach to your monitor to filter out
rf radiation (you'd have to seal the whole thing in a copper lined room
and leave the building if you wanted to make any real difference).
In my previous article I said that there is no significant x-ray
radiation coming from a video display terminal.  So let me just 
reiterate that anybody who wants to sell you a radiation filter 
that will make your monitor safer probably has some nice property 
in Florida for sale as well ;->.
