Does nuclear medicine perform radioactive iodine therapy?

They confirm that the prescribed radioactive material can be given safely, explain radiation precautions, administer the treatment, and arrange relevant follow-up. An endocrinologist, surgeon, or oncology clinician may also contribute to deciding whether this treatment fits your diagnosis and wider care plan.

Thyroid cells naturally take up iodine. Radioactive iodine uses that pathway to deliver radiation to thyroid tissue, including selected thyroid cancer cells that retain iodine uptake. It is commonly swallowed as a capsule or liquid under controlled conditions. Whether it is suitable depends on the type of thyroid tissue present, previous treatment, test results, and the clinical goal. The nuclear medicine team tailors instructions to the prescribed activity and your circumstances.

Give the team a complete medicine and supplement list, and follow any instructions about diet or thyroid medicines exactly. Report pregnancy, possible pregnancy, or breastfeeding before treatment because radioactive iodine can affect a developing baby and can pass into breast milk. Plan ahead for the contact, hygiene, sleeping, travel, and toilet precautions supplied by the department. Do not copy another patient's precautions; the required measures can differ according to the treatment plan and home setting.

Seek urgent help for breathing difficulty, marked neck swelling, inability to swallow fluids, collapse, or another rapidly worsening symptom. Contact your treatment team promptly if vomiting prevents you from keeping fluids down or if you vomit soon after taking the dose, since they must advise on both medical care and radiation handling. New severe eye pain or a sudden change in vision also needs prompt assessment. Use the emergency instructions provided at discharge when symptoms are serious.

Discuss the purpose of treatment, how preparation will be checked, which medicines should change, and what follow-up testing is planned. Ask for written radiation-safety directions that reflect your household, work, travel, and caregiving responsibilities. You can also clarify who to call after hours if you become unwell or cannot follow a precaution.
