As someone intimately involved in this issue for one of the major oilfield 
service companies, I can assure you that the requirements of IAEA and local 
regulators (e.g NRC, DHS, etc) have been acted on fully in all our 
installations throughout the world.
Of course, the security during transfer of these sources from our 
installations to the wellsites where they are utilized, and their security 
at these wellsites, are issues that are somewhat dependent on local 
political stability, security arrangements in conjunction with clients and 
local security forces and client implementation of security at their 
wellsite installations.

I am pretty sure that the other major service companies have taken similar 

Unfortunately, there will always be instances of people (among the many 
users of radioactive sources) slipping in their control of sources, as 
highlighted by the loss of two (soil?) gauges that "fell of the back of a 
truck" on a major highway in Houston yesterday, causing total chaos during 
rush hour yesterday.....
One was recovered while the other remains lost........

And, of course, having nukes accidently overfly the US shows that even 
those we "assume" are in control of their assets can screw up, with 
potentially greater consequence than the loss of a soil gauge......
