The only FDA approved radiation pills for nuclear fallout.

Radiation Pills For Nuclear Fallout

iOSAT™ tablets, Potassium Iodide (KI) radiation pills for nuclear fallout. Maybe you’ve heard of these pills before. Maybe not. It’s something that you might consider keeping with your other medicines, just in case. I do. Here’s some of what you need to know..

You might call them radiation pills. But they are specifically for thyroid protection from nuclear fallout – be it a nuclear weapon attack, or a reactor meltdown.

>> If and when ‘something happens’, it may be too late to get radiation pills. Supplies will be depleted near immediately from ensuing panic.

(jump down to my recommendation)

Radioactive fallout, from powerplants or weapons, can travel long distances. Almost all of the thyroid cancer from Chernobyl took place more than 30 miles from the reactor.

Thyroid cancer, especially among children, is the most common and dangerous effect from radiation exposure. More than 90% of the cancer at Chernobyl was thyroid related.

KI’s value was demonstrated at Chernobyl. More than 18 million people received the drug, and all were protected. But in areas where KI was not available, thyroid damage, including cancer, among children spiked to epidemic rates. All preventable.

The active ingredient is potassium iodide (KI). It is a form of extremely soluble iodine. As a result, the body quickly absorbs and stores it in the thyroid gland. The reason why it works is as follows.. The potassium iodide saturates the thyroid gland and fills it to capacity.

Why is this important? The body will reject the radioactive form and excrete it (RAI – radioactive iodine – a radioactive contaminant that causes thyroid cancer).

What’s the difference between iOSAT™ tablets and other brands of potassium iodide (KI) tablets?

iOSAT™ is apparently the only adult full-strength tablets for radiation protection
that have passed all FDA tests for purity, quality, safety, and efficacy.

How Many Radiation Tablets and How Often To Take Them..

Recommendation: Store one pack of 14 tablets per person for every location frequented (home, work, relative’s home, overnight bag, etc..).

iOSAT Potassium Iodide tablets (a.k.a. radiation pills) should be immediately available in the event of a nuclear radiation emergency (attack / fallout / meltdown).

To be most effective, the first dose should be taken 2-3 hours BEFORE exposure. However few of us know the time or the hour for if-and-when “it” happens.. So, as soon as is reasonably possible afterwards – assuming you are or will be in an affected area. Oh, and to cover my arss, “use as directed by public health officials”.

The manufacturer says, “Administer one dose every day (same time) until your family has evacuated to an uncontaminated area, and then stop administering the tablets (as directed by public health officials). Any remaining tablets will still be foil-sealed and available for a future need.”

Radiation Tablets For Children

From Anbex, the FDA approved manufacturer, “Children under 18 can receive an effective dose from half a tablet. However, KI is known to be very safe for children, so any child over the age of one could take a full tablet with no adverse consequences expected.”

What About The Shelf Life or Expiration Date?

iOSAT Tablets are FDA approved for 10 years from date of manufacture and should be stored unopened in a dry environment at room temperature.

  1. We have kept IOSAT tabs handy everywhere (house, vehicles, go bags etc) since Fukishima. When that event happened we started measuring the air (using an “inspector” radiation alert device) and kept a “log”. On many occasions we felt compelled to put iodine in our livestock tanks as well as feed all the livestock dried Kelp (from a reliable pre-Fukishima source). They did not like the taste, but they ATE IT ALL and DRANK IT ALL…so they must have known they needed it. With all the saber rattling, I felt compelled to update our supplies and have it readily handy everywhere again. They don’t really cost much, but could certainly save lives as needed.

  2. I was curious if you can inadvertently take too much iodine?
    Have started taking some different supplements and shakes, both have iodine in them, not something you usually see as an ingredient in stuff.
    I assume your body just passes excess through like most other stuff other than fentanyl, 🙄

    1. The one supplement i take orally for assisting prostate has iodine from several sources including potassium iodide.

  3. Prices seem stable for now.
    Seems the average is $15 to $17 depending on where you go.
    I liked it more when the average price was $9 per package but that was a few years back.

    If you can afford it, get some.
    The cool/dark/dry/thing is best storage.

    A long time ago I ordered one pound of potassium iodide in crystal form for making the saturated solution plus several 1 liquid oz brown dropper bottles.
    That stuff will if kept sealed last forever.

  4. folks i hate to whiz in your wheaties but do some research as in white papers . potassium iodide NO . potassium iodate YES .

    1. To col.kurtz,

      First of all, I’m not sure of your tone.. or intent.. however I will say the following..

      I am not suggesting that iosat is the only choice for radiation pills. Rather, it is the only FDA approved, given a set of criteria.

      So, lets briefly address the difference between iodide and iodate. Here’s a snippet from Pubmed (anyone can do their own research from a myriad of sources via web-search)..

      “Potassium iodide is the preferred thyroid blocker for personnel handling radioiodine and is recommended as a prophylaxis for the population in the near-field of a nuclear reactor which would be likely to be exposed to radioiodine in an accidental breach of containment.”

      On the other hand, apparently Iodate is a bit more stable, as iodide is readily oxidized to iodine and lost by evaporation when exposed to air (which is likely why the iosat suggested above is individually wrapped and sealed). I recently ordered more, and the so called expiration date is 10 years out.

      In conclusion, do whatever you like. Personally, my source is iosat which I discussed above.

  5. switch now while available . and get some QNOL co q10 . it’s expensive but the cheap brands are garbage . nacent iodine is good to have also .

      1. Have you noticed any difference in your overall health/energy etc from this? I have been looking into adding this to my supplements, this getting old stuff is kinda a problem if we arent on top of it. And the doctors “practicing” (with everyones health) just want to prescribe pharmaceuticals.

        I need a better source for my turmeric, i love the gummies ive been using but think they just are expensive candy
