>You may have an instrument or article with a sealed source in it that may 
be shipped under UN2911, but a sealed source (or calibration standard) by
itself is not an instrument or article.

How is a sealed source (or calibration standard) different from an 
electronic tube provided as an example in the 49CFR173.403 definition?  An 
electron tube by itself is not an instrument, it is an article.  A sealed 
source falls under the category of "... or similar instrument or article 
having Class 7 (radioactive) material in
gaseous or non-dispersible solid form as a component part."

Again, it is assumed that Mr. McCarn might ship the source from within or 
to the DOT jurisdiction of the US - 49CFR might not apply to his potential 
source shipment.
