PET/CT Decommissioning

Special considerations

• LYSO/LSO crystals — naturally radioactive (Lu-176); trace but detectable. Dispose per local regulations.
• Ge-68 rod sources — decay first (half-life 271 days), then dispose as radioactive waste.
• Hot lab — full nuclear safety decommissioning if on-site lab existed.
• NRC license amendment — required.

CT components

Standard CT decommissioning (tube, generator, gantry).

Activation

PET beam is not activating — no waiting period like linac.
