Thyroid blocker

Potassium iodide (KI) and potassium iodate (KIO3) are called thyroid blockers when used in radiation protection.[1]

If a person consumes a dose of one of these chemical compounds, his or her thyroid may saturate with stable iodine, preventing accumulation of radioactive iodine found after a nuclear meltdown or explosion.
