INSTRUCTIONS FOR DISPOSAL 
 
8.1
 
Disposal 
 
By international regulations, radioactive materials that are no longer required must be transferred to a 
licensed recipient for final disposition.  Cobalt-60 source assemblies that have depleted beyond their 
useful working life may be returned to authorized recipients using a source changer authorized for the 
specific model source assembly. 
 
Authorized recipients will provide any specific conditions to the shipper as required by regulatory 
authorities. As a minimum, sources that are transferred for a final disposition must be within a current leak 
test and properly secured within an authorized package before shipment. 
 
Damaged, cropped, modified or contaminated source assemblies may require special handling and 
special transport containers. Notify the authorized recipient for specific instructions in these 
circumstances.  
 
Depleted Uranium (DU) shielded exposure devices that are removed from service due to severe damage, 
worn through ‘S’ tubes or decommissioning reasons must be sent to a licensed recipient for final 
disposition. If the Type B transport status of a damaged exposure device is impaired, the exposure device 
must be transported without radioactive source assemblies. DU shielded exposure devices sent for final 
disposition must be properly packaged, surveyed, marked and labeled before placement into the 
transportation system.

disposition
