Frequent Questions

Should I take Potassium Iodide (KI) during a radiological emergency?

Never take potassium iodide (also known as KI) and never give to your children unless you have been specifically advised to do so by the health department, emergency management officials, or your doctor.

Potassium iodide is a non-radioactive form of iodine. KI can be useful in situations where radioactive iodine has been released into the environment. It works by filling a person’s thyroid gland with safe iodine so that harmful radioactive iodine in the environment is not absorbed. But KI is only useful in situations involving radioactive iodine, and it only protects the thyroid gland. It is not an “anti-radiation” drug.
