CDC Recommends Potassium Iodide in a Radiation Emergency

  • In a radiation emergency, some people may be told to take potassium iodide (KI) to protect their thyroid.
  • Do not take KI unless instructed by public health or emergency response officials or a healthcare provider.
  • There are limits to who should use KI and how much it can help. It only protects the thyroid from radioactive iodine (I-131) and does not protect other parts of the body from other types of radiation.
