We disposed of a Keleket-Barnes cobalt-60 teletherapy unit in September 1992.  
The source was 880 Ci.  Only Neutron Products was willing to quote us a price.
Their quote was $16200.  This price covered everything except fees for NRC 
inspections of their operations at our site (there were none).

They showed up on schedule, pulled the machine in less than 48 hours, and 
left us a clean room.  They brought everything they needed, and took 
everything away (head, stand, control panel, etc as well as source).
