Don't waste your money on those expensive pills. Or just get maybe one bottle to carry with you for emergencies. Go to http://www.postapplescientific.com/ and get the Potassium Iodide in USP form. You can get 26 grams (enough for 200 doses) for about 25 FRN's. Basically you just put 26 grams into a one litter bottle, then drip 5 cc's (same as 5 ml) onto a piece of bread and eat it. This would be your daily 130mg dose.
"Less than saturated Potassium Iodide (KI) solutions, when properly mixed, should give even more accurate dosages because there is more solution overall to be measured out per dose. For example, mixing and dissolving exactly 26 grams of Potassium Iodide USP into a one liter bottle of water, for example, produces 1000 ml of Potassium Iodide solution with a strength of 130 mg for each 5 ml of that Potassium Iodide (KI) solution. There are 200 of those 5 ml servings in that 1000 ml (1 liter). 5 ml can be easily and accurately measured out with a common graduated medicine dropper. 5 ml is also equal to one measuring teaspoon." --- Nuclear War Survival Skills
thinks about this. If you need to take ki, you are in a hell of a lot of trouble. the ole thyroid might get protected but the rest of you is just screwed. just remember radiation is not thyroid selective. Best thing to do? Get out of the area. Also, try not to leave near or downwind of a nuc plant. Of course, if you have lead suit, then just ignore this.
KI fills the thyroid with harmless Iodine so that radioactive Iodines can not enter. If you are in a shtf situation where you are having to take KI bug out asap or get the fallout shelter. Remember time distance and sheilding to lower your dose. All nuclear sites have to keep KI on hand to distribute in an emergency. Better to have it on hand to avoid the lines at the distribution center.
