Why is iodine used in nuclear attacks?

Potassium iodide protects the thyroid gland against internal uptake of radioiodines that may be released in the unlikely event of a nuclear reactor accident. The purpose of radiological emergency preparedness is to protect people from the effects of radiation exposure after an accident at a nuclear power plant.

Also know, why does iodine help with radiation?

KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.

People also ask, how much iodine should I take for nuclear fallout?

KI can be in the form of a pill or a supersaturated solution. The recommended daily dosage for an adult is 130 milligrams. If the thyroid absorbs all the iodine that it needs from the nonradioactive KI, then the radioactive iodine will not be absorbed and will be eliminated from the body mostly by way of the urine.

How long can you keep iodine?
