i happened to note:

we too have had experience incinerating carcs chock full o' microspheres 
(Ce-141, Sr-89, Cr-51, Sc-46, Sn-113) and our analysis of incinerator 
ash indicates very little if any of the activity goes up the stack but 
rather remains in the ash.... 
 
in the name of curiousity could you discuss this subject further??? 
 
if you can find the time, any experiences you have had with monitoring 
ash would be appreciated.
