James,
You mentioned stocking up on Potassium Iodide (KI). The head trainer at Medical Corps [1]–(I took their awesome class, thanks for giving it kudos)–developed Potassium Iodate (KI03). It has a huge benefit over KI, in that it doesn’t upset the stomachs of the people taking it [as much as KI]. Medicine is much more beneficial if you don’t involuntarily purge it.
Another thing I’d like to mention to SurvivalBlog readers is that KI and KI03 don’t expire, even if the bottles have expiration dates marked. Since it is not an organic–it a very basic chemical compound. Iodine might leach out and turn the tablets dark, but iodine is still iodine. Just mix it with food to cover the bad taste and it’ll still be effective. With Regards, – Cody (a 10 Cent Challenge [2] Subscriber)
