potassium iodide and nuclear power

[Timelord]

Potassium iodide is protection against radioactive particles accumulating in the Thyroid gland. It does not matter from what source. It does not protect against general external body irradiation. It is the internal dose, say from the thyroid or ingestion that your body has no defence against. Externally the body can tolerate a measured amount depending on other variable factors. A dirty bomb will have much more localised effects and so be leass threat generally. More of an economic catastrophy and a terror weapon. Effective all the same. TL.
