Potassium Iodide (KI)

In the event of a radiation emergency or accident that involves a release of radioactive Iodine, Potassium Iodide (KI) may be used to help prevent the risk of thyroid cancer. Local and state officials may ask citizens to evacuate or shelter-in-place as the primary public safety measure and use Potassium Iodide (KI) tablets as a supplemental protective measure in addition to evacuation or shelter-in-place.
