When I started worrying about a nuclear EMP, I also started worrying about fallout. I ordered a radiometer and some Potassium Iodide tablets from AMAZON. I bought about 3 cards of the tablets. One for me and one for the wife and one or two more for family members. If you ain't got 'em, you better get 'em. The cards that I got have the punch out pills and when and how to take them.
