Potassium Iodide Distribution

Mecklenburg County sits between two Duke Energy nuclear power plants, McGuire and Catawba. Due to their proximity to Mecklenburg County, residents and business should be prepared to protect themselves should a nuclear release affecting the health and safety of County residents occur.

In preparation of a possible nuclear release, the MCPH Preparedness Team provides potassium iodide (KI) tablets to Mecklenburg County residents and businesses who are within 10-miles of either 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.
