Radioactive iodine has been used as a treatment for thyroid disorders, most commonly hyperthyroidism, goitres and thyroid cancer since the 1940s. We have a range of general information to help you understand more about this treatment, how it is used and how safe it is. If you have any specific questions about your own treatment, or that of your family member or the person you are caring for, you should always speak to the medical team involved.
