That brave crew must know the odds against their long term survival. I thank them, and hope their sacrifice is not in vain.
More info on the potassium tabs. Important to know there are two types available, with (of course!) conflicting info regarding which is best. But most important to know there is a difference in DOSAGE amounts between the two.
The potassium iodide is referred to as KI, and that is the type described in thirty's post above with the tablet mg loads and dosages as described.
There is also potassium iodate, referred to as KIO3, and if you've purchased tabs in the past few years yours may be this type. This has the advantage of a longer shelf life (decades if unopened). Different mg in the tabs from the KI, and different dosages of mgs/tabs per day.
****************************
http://www.nukepills.com/potassium-iodate-vs-potassium-iodide.html*this site indicates the KI is superior to the KIO3 (bear in mind they sell only the KI, so FWIW)
http://www.baproducts.com/ki.htm*this site indicates that the KIO3 is superior for longer shelf life-again FWIW
Please read the cautions at this site for allergies, sensitivities, etc.<snip>
Potassium Iodate (KIO3) is a superior form of Potassium Iodide (KI) because of its extended shelf life and lack of bitter taste. The extra molecule of oxygen in Potassium Iodate (KIO3), can guarantee the Iodate's continued freshness without adding stabilizers. The Potassium Iodate we offer is a 85mg tablet, 200 tablets to a bottle. It should be kept sealed, dry, and out of reach of children. If unopened, it should be effective for decades. Use during a NUCLEAR EMERGENCY ONLY.
TAKING POTASSIUM IODATE
The tablets should be taken as a single daily dose within 3 hours of exposure, or up to 10 hours after exposure, although this is less effective. Authorities will tell you if there is a need to take KIO3.
The usual recommended “daily dose” is as follows:
Adults (including the elderly): 2 tablets
Children aged 3-12 years: 1 tablet
Children aged 1 month-3 years: ½ tablet
Newborns to 1 month: ¼ tablet
For young children or newborn children, the ½ or ¼ tablet may be crushed and taken mixed with milk or water. Under emergency conditions ½ tablet may be given to newborns as a starting dose.
In cases of prolonged exposure, repeat dosing may be necessary:
1-2 days for a “small” reactor leak
10 to 14 days for a “minor” event
Longer for a catastrophic event.

Again, be sure to read the full instructions and the cautions at the site on this drug.
Crikey, tough choices time I guess.
