Area Health Departments Distribute Potassium Iodide (KI)

KI Pills

Since 2002, potassium iodide (KI) has made available for residents who live within 10-miles of the McGuire and Catawba Nuclear Power Plants.

Mecklenburg County residents who live within 10 miles of either nuclear plant can obtain KI for their families during normal business hours throughout the year at the Cornelius, Huntersville, and Pineville Police Headquarters, as well as the Mecklenburg County Health Department (Beatties Ford Drive location). You are asked to call ahead to these locations prior to picking up KI. See more information about these distribution sites, potassium iodide (KI), and other places you can obtain KI.

KI distribution now includes those who work near area nuclear power plants, and provides additional opportunities for those who live nearby. Distribution sites for distribution sites in Mecklenburg, Gaston, Catawba, Iredell and Lincoln Counties.

Local Health Department's Role in Distributing KI 

The State of North Carolina is required to consider providing potassium iodide (KI) as a protective measure for the general public to supplement evacuation and sheltering in the event of a severe nuclear power plant (NPP) accident. This requirement is the result of a revision to the Nuclear Regulatory Commission's (NRC) section of its emergency preparedness regulations (10CFR50.47(b)(10) as published in the Federal Register (Volume 66, Number 13, page 5427) on January 19, 2001. The change became effective on April 19, 2001. More information is available on the NC Public Health web site

Potassium Iodide

KI is a type of salt that is added to table salt in small amounts to "iodize" the salt so that people have sufficient iodine in their diets to maintain normal, healthy thyroid function.  KI is also a non-prescription medication that is used to protect the thyroid gland in the event of a radiological emergency.  If taken at the appropriate time and at the proper dosage, KI blocks the thyroid gland's uptake of radioactive iodine, thereby reducing the risk of thyroid cancer.
