Truck-scale scrap detection systems

[burrill.s@adlittle.com]

Radsafers:

I am looking for some information on the truck scale detection systems used at  
scrap metal facilities to survey loads of scrap for sealed sources. The type of 
scrap I am looking at is primarily lead, however, any information related to 
steel scrap would also be helpful. 

Please forward information on any papers/publications on detection system 
efficiency and applicability, vendors, personal experiences with specific 
systems, etc.

Please reply to me directly:
