I once held "Secret". Never heard of "Q".

Were you military when you held your Secret? Q is a DOE clearance for nuclear secrets. Go to www.knoxnews.com and search the employment classifieds for the word "Clearance." You'll see Q mentioned a few times. Here in Oak Ridge, where we do a lot of nuke work, there's a lot of Q clearances.
