Why Should I Stock Potassium Iodide?

According to the CDC, in some radiation emergencies (usually nuclear power plant accidents), radioactive iodine may be released into the environment and enter the body through breathing or eating. This is known as internal contamination.

When the thyroid absorbs high levels of radioactive iodine, it can increase the risk of thyroid cancer in infants, children, and young adults many years after exposure. The thyroid is a gland in the neck that plays an important role in many body functions.

Potassium Iodide may be used as a thyroid blocker during a nuclear radiation emergency. Radioactive Iodine (I-131) can destroy the thyroid of humans and animals. Even small amounts of I-131 can cause cancer of the thyroid. By taking Potassium Iodide (KI), the thyroid becomes saturated with "good iodine" and cannot absorb the "bad iodine" I-131.

How KI Protects the Thyroid

KI and radioactive iodine are both types of iodine. According to the CDC, they are both absorbed by the thyroid. For KI to work, a person must take it before or shortly after exposure to radioactive iodine. When a person takes the right amount of KI at the right time, it can help block the thyroid from absorbing radioactive iodine. This happens because the thyroid has already absorbed the KI, and there is no room to absorb the radioactive iodine.
