Potassium Iodide 

If you are exposed to aerosolized I¹³¹, you inhale it into your lungs, and it quickly enters your bloodstream. If you consume contaminated water or food, I¹³¹ is absorbed from your gut and makes its way to your thyroid. This type of internal contamination can cause immediate illness or even death if the radiation exposure is high enough. Usually, however, internal exposure causes problems (cancer is the dreaded complication of radiation exposure) many months or years after the initial event.

Potassium iodide helps to limit internal contamination

Your thyroid's ability to absorb iodine is limited, but, on any given day, it usually has many unoccupied sites available for iodine storage. Once its capacity is reached, it stops collecting iodine from your bloodstream.

Since your thyroid cannot tell the difference between the various isotopes of iodine, any empty storage sites can be filled with either radioactive I¹³¹ or stable, non-radioactive iodine. KI is a stable form of iodine. If you begin taking KI immediately following a nuclear event, the stable iodine atoms will compete with radioactive iodine for absorption, and your thyroid will accumulate a lower radioactive load.
