Sånn apropos nevnt tidligere i tråden, om at det norske forsvaret ikke lenger lagrer jod til bruk ved atomkatastrofer:

Fant dette her http://www.mythyroid.com/iodine.html :

In the event of the detonation of a nuclear weapon or the release of radioactive material from a nuclear reactor, the most likely treatment of internal contamination would be the use of potassium iodide or iodate to prevent radioiodine from accumulating in the thyroid. The recommended daily dose of potassium iodide is 130 mg for adults, 65 mg for children 3 to 18 years old, 32 mg for children 1 month to up to 3 years old, and 16 mg for infants less than 1 month old. Potassium iodide must be taken shortly before exposure or within several hours after exposure to be effective. Both the Nuclear Regulatory Commission and the FDA have approved the use of potassium iodide in emergencies. Potassium iodide is widely available through the mail and the Internet. Too high a dose will result in iodism, but the risk of serious side effects with the recommended dose is extremely small. Chelating agents (calcium or zinc diethylenetriamine pentaacetic acid) are investigational drugs and are useful only if there is direct dispersal of plutonium or americium. Such agents are not very useful for the treatment of contamination with other radionuclides, and they are not useful after the detonation of a nuclear weapon.
