March 19, 2011 - "Hummm" Speaking of iodine I just heard that if you fear radiation poisoning, all you have to do is swap a little iodine on your skin. If it disappears after five minutes, then your skin absorbed it because your body needed it. If it's still there after five or ten minutes, then your body didn't need it and you can wash it off. I don't know if this is true or not. Anyone have an answer?
