>NO, Henry, you are not correct....

To reply in-kind...

YES, Dustin, I know I am not correct: now!  The same goes to Jeff, Bill, 
and everyone else who was kind enough to respond to my posts on this 

I stand corrected with respect to the individual sources' activity 
concentrations AND activity limits for exempt consignment not meeting the 
definition of Radioactive Material per 49CFR and possibly IATA , IMDG, and 
other regulations (i.e USPS) and tariffs (i.e. DHL, FedEx, UPS, etc.).

As the sources as described and will be offered for shipment/transport do 
not meet the definition of radioactive material and is therefore not 
subject to the US HMR, I concede that the sources do not have to be 
classified Class 7 Radioactive material or marked as either UN2910 or 
UN2911 for transportation in the US.  As I do not have the IATA/IMDG 
regulations in my office at this time (there are several on-site), I am 
not able to confirm that this is the case for international shipment / 

Also, I appreciate your suggestions in your subsequent post regarding DOT 
training.  However, it is not possible for a trainer to train one on every 
detail of the DOT, IATA, IMDG, and all other regulations.  There comes a 
point where after training, the trainee must carefully and thoroughly 
review the dangerous goods / hazardous materials transportation 
requirements themselves to insure that the packages and consignments he 
offers for shipment / transportation meet all of the applicable 
requirements prior to offering the packages and consignments.  This 
particular discussion and case has alerted me that I need to reset my 
thoroughness and care when preparing or offering radioactive packages for 
shipment / transportation or when offering guidance to others.

Thank you all for the discussion!
