INSTRUCTIONS FOR DISPOSAL
By international regulations, radioactive materials that are no longer required must be
transferred to a licensed recipient for final disposition. Iridium-192 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.
Contact AEA Technology QSA, Inc. for assistance in the transfer of DU shielded exposure
device for final disposition.
