Potassium Iodide (KI)


Potassium Iodide (also known by its chemical symbol "KI") is a small tablet that can be an effective means to protect the human thyroid from the effects of radioactive iodine, one of the radioactive isotopes that could be released during extreme emergency conditions at the plant.  KI will not protect the entire body from radiation exposure, only the thyroid.

It is important to understand that federal, state, and local health officials all agree that evacuation away from a radioactive plume is by far the best means of limiting radiation exposure.  Evacuation procedures and policies are in place to protect all citizens, but if you would like more information regarding this supplement, including how to obtain it, please contact the Manitowoc County Emergency Management office at (920) 683-4207
