Welcome to a brave new whirled. The nuclear melt-down in Japan has sent ripples through Ashland, as the antidote for Iodine radiation poisoning blew off the store shelves. This local chemist rides to the rescue by making 1000 CDC doses of Potassium Iodide for the local Southern Oregon community.
The idea of using potassium iodide is to prevent your body from absorbing radioactive iodine. The amount in a single dose is 135 mg KI - this is a lot of iodide. My recommendation is to take a dose now, then hold off for a few days. Then take another half-dose and that is enough, as long as there is no direct radiation cloud. If there is a direct cloud, take a full dose. Cut back the dose proportional to body weight for children, pets and elders.
Iodine is a necessary trace element in life systems, but it is not good in excess. Radioactive iodine is very much worse, and if your body is depleted of iodine, it will absorb the radio-iodine, which then can cause extremely serious damage. I can explain alpha, betas and gammas if there is interest.
Do not take this if you have thyroid problems. If you are worried about reactivity, take a drop of liquid and place it on your skin. If there is no immediate reaction, you are good to go. If you have medical worries - consult your doctor.
Net effect is that I have a three dose bottle for 10$ and a six dose bottle for $20. Call 541-324-7358 while supplies last.
