What You Should Be Doing NOW to Protect Yourself from Radiation

George Washington's picture

It is well-known that potassium iodide works to protect against damage from radioactive iodine by saturating our body (the thyroid gland, specifically) with harmless iodine, so that our bodies are unable to absorb radioactive iodine from nuclear accidents.

For example, the World Health Organization notes:

The thyroid gland is at particular risk from irradiation from radioactive iodine because the thyroid uses iodine to produce hormones that regulate the body’s metabolism.  The thyroid gland does not differentiate between non-radioactive and radioactive iodine.




When taken at the appropriate dosage and within the correct time interval around exposure to radioactive iodine, KI [i.e. potassium iodide] saturates the thyroid gland with stable (non-radioactive) iodine. As a result, radioactive iodine will not be taken up and stored by the thyroid gland.

However, KI only protects against one particular radioactive element, radioactive iodine, which has a half life of only 8.02 days.* That means that the iodine loses half of its radioactivity within 8 days.  For example, after the initial Fukushima melt-down, radioactive iodine was found in California kelp.

But the longer-term threat lies elsewhere.  As the New York Times noted – in addition to iodine-131 – the big danger is cesium:

Over the long term, the big threat to human health is cesium-137, which has a half-life of 30 years.


At that rate of disintegration, John Emsley wrote in “Nature’s Building Blocks” (Oxford, 2001), “it takes over 200 years to reduce it to 1 percent of its former level.”


It is cesium-137 that still contaminates much of the land in Ukraine around the Chernobyl reactor.




Cesium-137 mixes easily with water and is chemically similar to potassium. It thus mimics how potassium gets metabolized in the body and can enter through many foods, including milk.




The Environmental Protection Agency says that … once dispersed in the environment … cesium-137 “is impossible to avoid.”

Cesium-137 is light enough to be carried by the wind a substantial distance. And it is being carried by ocean currents towards the West Coast of North America.

Fortunately – while little-known in the medical community – other harmless minerals can help “saturate” our bodies so as to minimize the uptake of other harmful types of radiation.

The U.S. Department of Defense’s Army Medical Department Center and School explained in its book Medical Consequences of Radiological and Nuclear Weapons (Chapter 4):

One of the keys to a successful treatment outcome is to reduce or eliminate the uptake of internalized radionuclides before they can reach the critical organ.




The terms “blocking” or “diluting” agent can, in most cases, be used interchangeably. These compounds reduce the uptake of a radionuclide by saturating binding sites with a stable, nonradioactive element, thereby diluting the deleterious effect of the radioisotope. For example, potassium iodide is the FDA-recommended treatment to prevent radioactive iodine from being sequestered in the thyroid…. Nonradioactive strontium compounds may also be used to block the uptake of radioactive strontium. In addition, elements with chemical properties similar to the internalized radio-nuclide are often used as blocking agents. For example, calcium, and to a lesser extent phosphorus, can be used to block uptake of radioactive strontium.

The American Association of Physicists In Medicine agrees:

As does the book published in 2006 by the American Academy of Orthopaedic Surgeons, called Weapons of Mass Casualties and Terrorism Response:

After the U.S. military conducted above-ground nuclear tests on Bikini Island, scientists found that adding potassium to the soil reduced the uptake of radioactive cesium by the plants:

The first of a series of long-term field experiments was established on Bikini Island during the late 1980s to evaluate potential remediation techniques to reduce the uptake of cesium-137 into plants (Robison and Stone, 1998). Based on these experiments, the most effective and practical method for reducing the uptake of cesium-137 into food crop products was to treat agricultural areas with potassium fertilizer (KCl).

John Harte – Professor at the University of California at Berkeley in Energy and Resources and Ecosystem Sciences, a PhD physicist who previously taught physics at Yale, a recipient of the Pew Scholars Prize, Guggenheim Fellowship,  the Leo Szilard prize from the American Physical Society, and who has served on six National Academy of Sciences Committees and has authored over 170 scientific publications, including six books - notes:

Marine fish are usually about 100 times lower in cesium-137 than are freshwater fish because potassium, which is more abundant in seawater, blocks uptake of cesium by marine organisms.

The same is true in mammals.  The U.S. Department of Health and Human Services’ Agency for Toxic Substances and Disease Registry notes:

Cesium is a close chemical analogue of potassium. Cesium has been shown to compete with potassium for transport through potassium channels and can also substitute for potassium in activation of the sodium pump and subsequent transport into the cell.




Elimination rates of cesium may be altered by potassium intake.  Following the intraperitoneal injection of 137 Cs in rats, a basal diet supplemented with 8–11% potassium resulted in cesium clearance of 60 days compared to about 120 days for rats receiving the unsupplemented basal diet that contained 1% potassium
(Richmond and Furchner 1961). After 20 days on the diets, rats receiving supplemental potassium had body burdens of 137 Cs that were one-half those of the rats not receiving supplemental potassium. This finding shows that  supplemental potassium reduces the uptake and increases the elimination of ingested 137 Cs.

Dr. Ingrid Kohlstadt – a medical doctor with a master’s of public health, on the Faculty at the Johns Hopkins Bloomberg School of Public Health, editor of the best-seller Food and Nutrients in Disease Management – says that the same is true for humans:

Plutonium is treated like iron by our bodies. So getting enough iron will help reduce absorption of plutonium. And see this. (Plutonium is a very heavy element, and so normally cannot travel too far. Therefore, adequate iron intake is primarily important for those living in Japan.)

Here are the recommended daily allowances (RDA) for various minerals (data from the U.S. Department of Agriculture):

You can buy calcium, potassium, iron supplements. You can also buy non-radioactive strontium supplements.  Or incorporate foods high in calcium, potassium, and iron.

(Selenium also helps protect our bodies from radiation. See  this, this and this.)

In addition to these minerals, getting enough of certain vitamins is helpful.

A number of scientific articles conclude that Vitamin A helps to protect us from radiation. See this, this and this.

Numerous studies show that Vitamin C helps to protect the body against radiation.

Vitamin D can help repair damage to DNA, and may help protect against low-level radiation.   As Science Daily reports:

Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body’s main protections against damage from low levels of radiation. Writing in the International Journal of Low Radiation, Hayes explains that calcitriol, the active form of vitamin D, may protect us from background radiation and could be used as a safe protective agent before or after a low-level nuclear incident.




“Vitamin D by its preventive/ameliorating actions should be given serious consideration as a protective agent against sublethal radiation injury, and in particular that induced by low-level radiation,” concludes Hayes.

It takes a couple of weeks or months to build up our body’s levels of Vitamin D.  You cannot just pop a bunch of pills and raise your Vitamin D level.   You should never take more than the recommended dose, and  – even if you did – it wouldn’t raise your vitamin D level all at once.  As such, we should start now …

Vitamin E has also shown promise in protecting from low-level radiation, at least in animal studies. Here and here.

Here are the RDAs for vitamins (data from the U.S. Department of Agriculture):

You can buy vitamin supplements, or eat foods rich in vitamins A, C, D and E.

Antioxidant-rich foods also help protect you against low-level radiation. See this for the science behind antioxidant protection from radiation, tips on inexpensive, anti-oxidant rich foods ... and other valuable tips on how to protect yourself from radiation.

The bottom line: starting to saturate your body now with the right types of healthy vitamins, minerals and antioxidants can help protect you against radiation if it hits in the future.

Postscript: We only advocate taking the RDA for various nutrients, which is healthy for you anyway. We are not talking about mega-doses.

We have spent hours looking through medical journal articles for other foods which help protect against radiation.  Here are the results.

For a more complete discussion of commonly-accepted scientific consensus on different prevention and treatment options, please review the Army’s Medical Consequences of Radiological and Nuclear Weapons and the The American Association of Physicists In Medicine’s Medical Management of Radionuclide Internal Contamination.

You should not take potassium iodide supplements unless you are exposed to high doses of radioactive iodine, because it can damage some people's health.  These supplements are only for short-term, high-dose ratiation protection, not for years-long low-dose exposure. For long-term exposures, a daily, baseline level of iodine is healthier.

Potassium iodide is found in most common table salt.  However, if exposed to air, the iodine content can largely evaporate within a month or so.  So store your salt in as air-tight a condition as possible.  Also, it is important not to ingest too much potassium iodide, and most of us already get a lot of salt in our diets from processed foods.  (The RDA for “sodium” – i.e. salt – is listed in the table above on the RDAs for various minerals)

Here is RDA for iodine:

And here are some iodine-rich foods.

Highly recommend listening to anything on this issue by Dr. Simon Atkins


He not only discusses other effective alternatives to protect oneself from Fukushima, but as an atmospheric scientist, he also discusses how Fukushima radiation will be very hard for the sheeple to ignore by Spring 2014 in this country (that's assuming we make it past the Tepco dummies dropping the fuel rods in reactor 4 this month.

Also, do NOT eat ANYTHING from the Pacific Ocean areas, that includes Alaskan salmon and fish such as tuna caught off the Northwest coasts. They are tainted with radiation and the USA does not monitor this anywhere near adequate.

Another issue I hope GW gets into is how electromagnetic / geomagnetic storms directly affect people. Before you color me crazy, consider the Federal Reserve of Atlanta's confirmation of this.

(Playing the Field: Geomagnetic Storms and the Stock Market
Anna Krivelyova and Cesare Robotti
Working Paper 2003-5b October 2003).

The real concern over ISON isn't the goofy theories one hears about, but how ISON going through earth's magnetic field will impact the (shall we say) um the perpetually angry, borderline crazy subsets of folks around the world.

But I digress. Asides from GW, Enenews.com is an excellent site that updates the daily idiocy in Japan.

Thank you for your continued diligence GW.

In addition to select super foods, I regularly use calcium bentonite clay which not only removes radiation from the body but chelates heavy metal toxins including aluminum (that seems to be everywhere) as well as the high arsenic levels in food like rice. Plenty of good info out there that anyone can find on google.

This is total crap and grossly irresponsible.  Taking iodine has dangerous side effects.  Excessive calcium will damage your kidneys and heart.  Excessive iron will destroy your liver and kill you.  These should only be done if you have an extraordinately large radiation exposure.  Unless you live in Japan and relatively near the damaged reactors, your radiation exposure is de minimus and not the radiation hazard you should worry about.  For example, seawater contains many orders of magnitude more radiation from naturally occuring Potassium 40 than Cesium 137.

Here's some real, practical advice to avoid radiation exposure...

(1) STOP SMOKING!!!  Tobacco plants have a unique affinity for absorbing raidoactive polonium.  Smoking a pack a day exposes you to more than 1000 mrems per year.

(2) Check for radon.  See if you live in a high risk area for radon, and if so, get your house tested.  100's of mrems/year, and much more in some areas.

(3) Manage your medical imaging, especially CT's and PET scans.  Some of these procedures expose you to 1000's of mrems, i.e. years of background exposure.

(4) Consider your air travel.  Long distance air travel, especially over the poles exposes you to lots of extra mrems.

This is the best yet GW, well put together, everythings there.  Maybe QN should go over an show those cocksuckers how it's done eh?   LOL!!!

Cindy_Dies_In_The_End's picture

Perhaps GW should have been clearer, I would hope most of us here know to take the daily recommended dose one finds in a vitamin, as opposed to the type one takes a few minutes before screaming, getting liquored up and yelling "Alas Babylon" while running for the fall out shelter.

That being said, better to stock up on this while its readily available.

If you are so smart, thesis, why don't you explain to the class about how radiation bio accumulates in the body after you read the make up of the fuel rods in the reactor 4 pool.

pondview28's picture

Quantum is entirely correct. Your attempt at snark is a complete fail. It should be added that potassium supplementing can be very dangerous. Check out the recommended daily requirements and the amount in a typical potassium supplement. On the order of 1/100 the amount. Take more at your peril.
Although this GW post is factual it is mostly irrelevant to Fukushima and US residents. His series of posts on Fukushima is easily debunked at most every turn. They use hearsay, conjecture, and also quotes from many nuclear ax grinders to a paint a picture that is not consistent with is actually happening or what may occur. Do your own research. GW is highly, highly biased and not the place to get a well-rounded picture of the actual dangers. It is a mess for sure, but not of the magnitude this series of posts describes it to be.

Are you on the payroll of the nuclear power industry?

Fish Gone Bad's picture

Those are some great tips and I thank you for them.  The potassium 40 must be a talking point that I have really missed.  Let's talk about tritium.  You know, the stuff that can eat stainless steel pipes and is leaking out of every single nuclear plant.  Tritium is scorching hot stuff - Tritium's radioactivity is 9650 curies per gram (357 TBq/g).  Meanwhile, Cesium 137's radioactivity is ONLY 3.2 TBq/g, less than a tenth of tritium's.  Tritium can and does go anywhere water can go, and it does.

No one can do anything about naturally occuring potassium 40.  That does not make being exposed to additional sources of radiation OK.

shameless promotion of the little angry fish ==> cursing fish cafepress <== shameless promotion of the little angry fish.

And thank god for tritium, else the illuminated reticle on our trijicon scopes as well as our night sights on our pistols would not be. Oh, and our H bombs would fizzle. You don't want the dying Russian empire's weirdos or china's or any other psycho states to imagine for a second your nukes are impotent or unreliable, which they would be and will be without keeping their tritium charge up to designed strength.

any thoughts on the natural iodine AJ is selling on infowars.com?

George Washington's picture

My assumption is that AJ has top-quality potassium iodide.  It would be very good to have that for when Fuku pumps out high radioactive iodine levels.

Buy it now - while you still can. But don't take it until then.

In the meantime, take much lower doses of iodine to have some more low-level saturation.

I'm not a healthcare professional, not diagnosis or advice ...

THis is a really good discussion between two doctors about iodine (from 2011 - before the severity of Fuku became apparent).

If in two months their remedial efforts at Fukushima plant goes bad, as it may well, then we will end up with a very big radiation problem...the scope of which to be determined.......BUT you will NEVER be told just how bad. You will have to rely on third parties measuring shit and telling you how bad things are...as has been the case alreay. They lied their asses of from day one about this stuff.

IF things go badly at Fukushima, watch the money of the big corporations....they will know before you and me.

I live in southern Mexico and since no one drinks the tap water here (potable water is bought in 5 to 8 gallon plastic, returnable jugs) the government is kind enough to poison us with dollops of sodium fluoride in all the commercial salt as well as all the major brands of toothpaste.  I am not much into salt myself and have a life time supply of sea salt in the cupboard, but it's nice to know that the governments are helping to make us even stupider than God intended.  Dumb and dumber.  How thoughtful.  Every time I eat at a restaurant though, I feel my IQ go down 5 points.  I thinks it's about minus 25 now.

Good to hear from you Buzzard. Don't be a stranger. I was always a fan of your posts.

And to GW (and all other posters) ... I am surprised no one stated the obvious.

What is the situation with the Nuclear plants and spent rods in the U.S.?
(of course, readers outside the U.S. should be asking the same about their respective countries).

I don't see any signs of Fukushima having kindled a critical mass (sorry for the pun .. couldn't resist) debate about nuke plants and fuel rod storage.

Rod storage has always been contentious of course. For obvious reasons as it's essentially Forever.  The NIMBY (Not In My Backyard ... for all you non U.S. acronym savvy readers)  factor being first and foremost.

Far as I know, only the Southern California plant got closed down due to post Fukushima concerns about plant integrity. That begs the question ...what became of the spent fuel rods at San Onofre. Are they still sitting there. Probably (let's hope there's no tsunami.  I've driven by and it doesn't appear to be that far removed from sea level).

This nuke plant issue seems to have gone walkabout. Not much discussion or debate is visible these days even though Fukushima is very much in the news.  And what ever happened about the promise of thorium based nuclear.

Guess fracking (poisoning groundwater for immediate gratification), and an imploding economy as obviated the pressing need for more long term solutions.


pondview28's picture

They are on-site in pools or cask storage at every plant. The utilities have been paying the government for thirty years to develop and build a storage site. Not done yet purely due to politics. Utilities have had to reconfigure pools to store far more spent fuel than originally planned. If a problem occurs it will mainly be due to this high density storage. Government could alleviate almost all concerns with fuel storage in very short order.

That is good advice, like to be sand bagging as protection from a flood, but only IF the flood does not exceed the level of the bags. As with all preparations, they make sense, but only up to the point where the problems do not overwhelm the possible preparations. My general view is a kind of sour grapes rationalization that it is not possible to actually be prepared, because the storms coming are bigger than anything which can be prepared for.

I am NOT saying to do not attempt to be prepared. I am saying that my opinion is that all of these things are going to gang up on us to a level for which no preparation is practically possible. ... I hope I am wrong ... However, generally speaking, when it comes to being slightly prepared for relatively survivable disasters, the bigger picture appears to me to be that 99% of the population are NOT prepared. In that context, the 1% that are attempting to be prepared are probably not able to prepare for what happens when the other 99% are faced with the real circumstances that they were not prepared for.

Over the longer term, nature selects for diversity, because it favours adaptability, which is the most crucial thing for longer term survival. However, nature also allows for maximum short-term specializations to take advantage, in that short term. Our current society has obviously been driven to be taken over by monopolizing forces, which wanted to make people dependent and vulnerable. Everything that we should be doing is usually diametrically opposite to what we actually are doing, because the government has been taken over to maximize the short-term advantages of the privatizing special interests, who ran away within a positive feedback of getting away with frauds, which enabled them to reinvest the profits from those frauds in more frauds.

The entire uranium atomic energy business was an expression of those social trends in the first place. Those problems are probably trillions times worse than anyone anywhere can actually be prepared for, although, it still makes sense to try, in case things do not actually get that bad. However, as far as I can tell, the runaway powers of monopolists, based on legalized lies, backed by legalized violence, are automatically getting worse, faster, and therefore, the 99% who are not prepared are more probably going to become even less prepared, and therefore, even more overwhelm the 1% that tried to prepare, whenever those preparations become necessary, due to disasters, or megadisasters actually happening.

Theoretically, Planet Earth should be operated as as Life Boat, made out of as many local Life Boat components as possible. However, the runaway power of the monopolists have made their globalized system become one huge, extended systemic risk, where its sinking does not leave enough life boats, or even life rafts, left afterwards.

Atomic power generation was developed in the manner it was because its systems dovetailed into making atomic weapons. Uranium mining became one of the worst industries there has ever been, while the kinds of atomic energy plants actually made were about the stupidest possible design, as even those who designed them protested against. (But then, were fired as whistle blowers usually are, when they interfere with the short-term profits of the monopolizing powers.)

The fundamental problem is that the short-term concern of being the best at dishonesty, and backing that up with violence, has dominated everything that Neolithic Civilization actually did. Therefore, the most insane possible atomic power industry was the one that was actually built. Given that context, which continues to still automatically get worse today, I find it practically impossible to believe anyone could really be "prepared" for the megadisasters and social storms that are coming ... Although, again, I am not suggesting not to try ...
