Abstract:	This fact sheet outlines the use of radioactive iodine (RAI) for thyroid imaging and treatment of thyroid disorders. The author first reminds readers that iodine is essential for the proper function of the thyroid gland, which uses it to make thyroid hormones. Iodine is made into two radioactive isotopes that give off radiation for medical uses: I-123, which is harmless to thyroid cells; and I-131, which destroys thyroid cells. I-123 is used to take diagnostic pictures and determine the activity of the thyroid gland; no special precautions are required after the use of I-123. I-131 is given to destroy overactive thyroid tissue that is causing hyperthyroidism or, in larger doses, to destroy thyroid cancer cells. The fact sheet outlines the long-term risks of I-131 RAI and notes special concerns for those who receive RAI treatment. One chart lists the instructions to reduce radiation exposure to others after I-131 RAI treatment, specifying the number of days recommended for each of a variety of activities, such as returning to work, preparing food for others, traveling, and avoiding contact with small children and pregnant women. Readers are referred to the American Thyroid Association website at www.thyroid.org for more information. 1 table. 2 references.
