Facts About Potassium Iodide (KI) | CDC

Potassium Iodide (KI)

As part of Harnett County’s continuing emergency preparedness effort, we continue to make available free potassium iodide tablets (KI) to county residents who live, work, and or/attend schools within a 10-mile radius of Emergency Planning zone (EPZ) of the Harris Nuclear Power Plant.

Potassium iodide is a non-prescription medication that is used to protect the thyroid gland, in the event of a nuclear release or radiological emergency. If taken at the appropriate time and at the proper dosage, potassium iodide can block the intake of radioactive iodine, therefore reducing the risk of thyroid cancer.

Potassium iodide should NOT be taken unless directed by public health officials. If taking potassium iodide is recommended by public health officials, residents and businesses should still follow evacuation or shelter-in-place recommendations as well.

 Call the Harnett County Health Department at 910-893-7550 for more information and for how to pick up Potassium Iodide tablets.
