I imagine there's a "de minimis" quantity.  We didn't declare the cesium 
in the CSAC that we hand carried, and I'm pretty sure people have hand 
carried SRS Rb sources.

off of the MSDS from Symmetricom/Microsemi

"All Symmetricom’s rubidium product can be shipped both domestically and 
internationally as a non-hazardous product. Symmetricom has received 
letters of interpretation from both the United States Department of 
Transportation (US DOT)Ref. No. 08-0154 and the International Air 
Transport Association(IATA) stating that Symmetricom’s rubidium product 
are not considered a hazardous Class 4 material in transportation.
