Potassium Iodide tablets
Iodine supplement are effective in blocking thyroid uptake of radioactive Iodine (I131) but have NO OTHER PROTECTIVE EFFECT – NONE! If you do not have Potassium Iodide tablets or supplement-grade iodine, use tincture of Iodine by painting it on your skin: paint 8 ml of a 2 percent tincture of Iodine on the abdomen or forearm approximately 2 hours prior to I-131 contamination. That would be now.
Do it daily until further notice. You will probably notice a general increase in your general health and well-being, as many people are chronically Iodine deficient; but do not over do it!.
Do not drink or swallow other forms of iodine because they are poisonous.
Do not drink Betadine or iodine water purification tablets
