All infants, including breast-fed infants need to be given the dosage of KI (potassium iodide) recommended for infants.

Infants have the highest risk of getting thyroid cancer after being exposed to radioactive iodine. Young children and people with low amounts of iodine in their thyroid are also at risk of thyroid injury. The thyroid glands of a fetus and of an infant are most at risk of injury from radioactive iodine.
