== Don't use wikipedia to try and delude people == 

 The OP was about as insipid as I've seen.  If somebody hears about Strontium-90 and goes here to learn, don't have a one line OP that says nothing.  The source for the edit (which of course will be contested) is the American EPA, which means there is no reason at all to attempt to beat around the bush.  Strontium-90 is the most dangerous part of fallout and reactors, trying to hide that is ridiculous.  It makes a mockery of Wikipedia.
