Potassium Iodide (KI) 
Based on medical studies, federal guidance and an increased public interest in KI-potassium iodide, New York State and Westchester County have developed a program to provide KI-potassium iodide to residents who live, work or travel within the 10-mile Emergency Planning Zone.

KI protects only the thyroid gland from radioactive-iodine that may be emitted during a radiological emergency. 

KI offers no protection for other forms of radiation, nor does it protect any other parts of the body from radioactive materials. 

KI provides no protection against external irradiation of any kind. 

The FDA emphasizes that the use of KI should be as an adjunct to, not an option “in lieu of” evacuation, sheltering, and control of foodstuffs.
