First, THIS IS NOT A TREATMENT FOR Radio Iodine 131. READ the linked article
Cesium 137 has a half life of 30 Years which is why you don't want it to accumulate in your body after a release of the isotope (from whatever cause).
Iodine 131 has a half life of only 7 days, so it is a different problem than Cesium 137.
http://www.naturalnews.com/2017-03-28-health-ranger-awarded-u-s-patent-for-breakthrough-anti-radiation-formula-that-eliminates-cesium-137-from-your-body.htmlSadly, the product is NOT available for public purchase (Read the article). It is only intended for use in the event of a contamination problem.
I quote from the article:
"...
(In a pinch, for anyone who wants to take advantage of this discovery in a real emergency, you can simply
consume zeolites, knowing that you’ll also be consuming large quantities of aluminum at the same time. But in the race of aluminum vs. cesium-137, it’s far more important to eliminate the cesium.)
..."
Do you own due diligence on this, but the article makes it very clear why you may and MAY NOT want to use this option.
OPINION: The reference to aluminum being a problem is debatable and the subject of much argument in the "health" products community. Again, do you own research. Should you chose to stock zeolites in your prepper supplies, it is readily available at most
garden shops.
If you don't need it, zeolite still makes a good soil amendment.
