Craig-

You mention potassium iodide. Here's an interesting discussion of alternatives, one being the topical application of a 2 percent tincture of Iodine.

I know that everyone on this forum is mindful of the obvious: in the wrong hands, or administered to the wrong people, any of these "cures" could be worse than the "disease."

Your question about the likelihood of a nuclear event...I'm not a doomsdayer by any stretch, but clearly 9/11 [should have] taught us that we no longer have the luxury of believing that certain events are "unthinkable." Particularly if one puts any credence in articles such as "Al-Qaida nukes already in U.S.".

Just my $.02.
