Travel documents after radionuclide therapy in China

Share your itinerary before discharge

Tell the nuclear medicine team about planned flights, connections, ground transport and companions. Ask what written radiation-protection instructions apply to your circumstances and whether your planned itinerary fits them. Discharge and permission to board are separate decisions.

Ask for a travel letter

Some border or airport monitors can detect radiation after treatment. Ask whether the department can provide a letter explaining the treatment, with your name as shown on the passport, the procedure and date, and a contact that can verify it. Ask if a translation is available or needed.

Check the carrier and keep the letter handy

Confirm documentation or advance notification with the carrier for your route. Carry the letter where you can reach it at screening and provide it if asked. It explains a potential reading; it does not guarantee boarding or clearance. If your itinerary changes, check it with the treating team.
