Re: RE k-40

Not a problem, Elizabeth. We can 'just explain' that: "It's well within the
variation of the background radiation coming from the CRT anyway."  

(Of course that doesn't work for the LNT when EPA says 15 mrem/year in
background that varies from 70-~80 mrem/yr to 700-800 mrem/year, with
7,000-8,000 in some localities - with no adverse effects!? :-)
