Patients are asked to follow some radiation precautions after treatment in order to limit radiation exposure to others (see below). There is no clear evidence that RAI leads to infertility. The Wolff-Chaikoff effect is an effective means of rejecting the large quantities of iodide and therefore preventing the thyroid from synthesizing large quantities of thyroid hormones. The amount of radiation exposure markedly decreases as the distance from the patient increases. 2000 Jun;78(6):660-7. doi: 10.1097/00004032-200006000-00008.

It is proposed that iodopeptide(s) are formed that temporarily inhibit thyroid peroxidase (TPO) mRNA and protein synthesis and, therefore, thyroglobulin iodinations. Potassium iodide (KI) to block the thyroid from exposure to I-131: current questions and answers to be discussed. Its main effects are to decrease the response of the thyroid to thyrotropin (TSH); to acutely inhibit its own Calcium iodate-another effective blocker of radioiodine uptake by the thyroid gland. Iodine, in the form of iodide, is made into two radioactive forms of iodine that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells). 2013 Aug 30;6(1):10. doi: 10.1186/1756-6614-6-10.
