Description: Radioactive iodine (131-I) is a radioactive isotope that is administered orally, in a liquid or capsule form.Thyroid tissue concentrates iodine.

In the setting of thyroid cancer, all normal tissue should be removed (total thyroidectomy) along with any gross neck disease (neck dissection) in order for any residual microscopic disease or distant metastases to receive an optimal dose.(Ref: Practical Management of Thyroid Cancer: A Multidisciplinary ApproachErnest L.
