Most of the radioactive iodine not taken up by your thyroid will be eliminated within two days after treatment.
For DIAGNOSTIC radioactive iodine (iodine-123), it lasts a few days until you can’t detect it.
For THERAPEUTIC radioactive iodine (iodine-131), it lasts about a month. If you get iodine-131, your doctor may give you more detailed instructions.
