True facts about ocean radiation and the Fukushima disaster

  • Simpsons guide to radiation

On March 11th, 2011 the Tōhoku earthquake and resulting tsunami wreaked havoc on Japan. It also resulted in the largest nuclear disaster since Chernobyl when the tsunami damaged the Fukushima Daiichi Nuclear Power Plant. Radioactive particles were released into the atmosphere and ocean, contaminating groundwater, soil and seawater which effectively closed local Japanese fisheries.

Rather unfortunately, it has also led to some wild speculation on the widespread dangers of Fukushima radiation on the internet. Posts with titles like “Holy Fukushima – Radiation From Japan Is Already Killing North Americans” and ”28 Signs That The West Coast Is Being Absolutely Fried With Nuclear Radiation From Fukushima” (which Southern Fried Science has already throughly debunked ) keep popping up on my facebook feed from well-meaning friends.

I’m here to tell you that these posts are just plain garbage. While there are terrible things that happened around the Fukushima Power Plant in Japan; Alaska, Hawaii and the West Coast aren’t in any danger.  These posts were meant to scare people (and possibly written by terrified authors). They did just that, but there is a severe lack of facts in these posts. Which is why I am here to give you the facts, and nothing but the facts.


The radioactive rods in the Fukushima power plant are usually cooled by seawater [CORRECTION: they are usually cooled by freshwater. As a last ditch emergency effort at Fukushima seawater was used as a coolant.]. The double whammy of an earthquake and a tsunami pretty much released a s**tstorm of badness: the power went out, meltdown started and eventually the radioactive cooling seawater started leaking (and was also intentionally released) into the ocean. Radioactive isotopes were also released into the air and were absorbed by the ocean when they rained down upon it. These two pathways introduced mostly Iodine-131, Cesium-137, and Cesium-134, but also a sprinkling of Tellurium, Uranium and Strontium to the area surrounding the power plant.

There aren’t great estimates of how much of each of these isotopes were released into the ocean since TEPCO, the company that owns the power plant hasn’t exactly been forthcoming with information, but the current estimates are around 538,100 terabecquerels (TBq) which is above Three-Mile Island levels, but below Chernobyl levels. And as it turns out, they recently found contaminated groundwater has also started leaking into the sea. TEPCO, the gift that keeps on giving.


Units of Radiation are confusing. When you start reading the news/literature/blogs, there are what seems like a billion different units to explain radiation. But fear not, I’ve listed them below and what they mean (SI units first).

Becquerel[Bq] or Curie[Ci]: radiation emitted from a radioactive material  (1 Ci = 3.7 × 1010 Bq)

Gray [Gy] or Rad[rad]: radiation absorbed by another material (1Gy = 100 rad)

Sieverts[Sv]* or “roentgen equivalent in man”[rem]: how badly radiation will damage biological tissue (1 Sv = 100 rem)

Simpsons Guide to RadiationYou can convert from Grays and Rads to Rem and Sieverts, but you have to know what kind of radiation it is. For example alpha radiation from naturally occurring Polonium-210 is more damaging to biological tissues than gamma radiation from Cesium-137. Even if you absorbed the same number of Grays from Cesium or Polonium, you would still effectively receive more damaging radiation from Polonium because the number of Sieverts is higher for Polonium than Cesium. And kids, Sieverts and Seavers  are both dangerous to your health but please don’t confuse them.


Cesium-137 is product of nuclear fission. Before us humans, there was no Cesium-137 on earth. But then we started blowing stuff up with nuclear bombs and VOILA!, there are now detectable, but safe, levels of Cesium-137 in all the world oceans.


There are a bunch of maps being thrown around on the internet as evidence that we are all going to die from Fukushima radiation. I’m going to dissect them here. Apologies in advance for dose of snark in this section because some of these claims are just god awful. Spoiler: radiation probably has reached the West Coast but it’s not dangerous.

MAP OF TERROR #1: The Rays of Radioactive Death!



This is not a map of Fukushima Radiation spreading across the Pacific. This is a map of the estimated maximum wave heights of the Japanese Tohuku Tsunami by modelers at NOAA. In fact, tsunamis don’t even transport particles horizontally in the deep ocean. So there is no way a Tsunami could even spread radiation (except maybe locally at scales of several miles as the wave breaks onshore). Dear VC reporter, I regret to inform you this cover image could be the poster child for the importance of journalistic fact-checking for years to come.


I mean I guess this is a bit better. At least this map used an ocean model that actually predicts where radioactive particles will be pushed around by surface ocean currents. But it still gets a BIG FAT FAIL. The engineering company that put this image/piece of crap out there couldn’t even be bothered to put a legend on the map. Their disclaimer says “THIS IS NOT A REPRESENTATION OF THE RADIOACTIVE PLUME CONCENTRATION.” Then what do the colors mean?


It’s true, oceanographic models have shown that radiation from Fukushima has probably already hit Aleutians and Hawaiian Island chain, and should reach the California Coast by Fall 2014 [Beherns et al. 2012]. The map above is showing the spread of Cesium-137 from the Fukushima reactor would look like right now, I mean radiation is apparently EVERYWHERE! But what is missing from most of the discussion of these maps is what  the colors ACTUALLY mean.

We shall now seek guidance from the little box in the upper right hand corner of the map called the legend**.  The colors show how much less radioactive the the decrease in the radioactive concentrations of Cesium-137 isotopes have become since being emitted from Fukushima. For example, the red areas indicate the Fukushima Cesium-137 is now more than 10,000 times less radioactive concentrated than when released. The California Coast, more than a million times less. The punchline is that overall concentrations of radioactive isotopes and therefore radioactivity in the Pacific will increase from Pre-Fukushima levels, but it will be way less than what was seen in coastal Japan and definitely not enough to be harmful elsewhere (we’ll get to more of that later).

** As Eve Rickert has thoughtfully pointed out, my description of the image is a little confusing. I’ve added corrections in blue to clarify.


Practically, what does ten thousand or a million times less radiation mean? It means that these models estimate the West Coast and the Aleutians will see radiation levels anywhere from 1-20 Bq/m3,while Hawaiian Islands could see up to 30 Bq/m[Beherns et al. 2012, Nakano et al. 2012,  Rossi et al. 2013 ].

I could write a small novel explaining why the numbers differ between the models. For those that love the details, here’s a laundry list of those differences: the amount of radiation initially injected into the ocean, the length of time it took to inject the radiation (slowly seeping or one big dump), the physics embedded in the model, the background ocean state, the number of 20-count shrimp per square mile (Just kidding!), atmospheric forcing, inter-annual and multi-decadal variability and even whether atmospheric deposition was incorporated into the model.

Like I said before, the West Coast will probably not see more than 20 Bq/mof radiation. Compare these values to the map of background radiation of Cesium-137 in the ocean before Fukushima (from 1990). Radiation will increase in the Pacific, but it’s at most 10 times higher than previous levels, not thousands. Although looking at this map I would probably stop eating Baltic Herring fish oil pills and Black Sea Caviar (that radiation is from Chernobyl) before ending the consumption of  fish from the Pacific Ocean.



No it will not be dangerous. Even within 300 km of Fukushima, the additional radiation that was introduced by the Cesium-137 fallout is still well below the background radiation levels from naturally occurring radioisotopes. By the time those radioactive atoms make their way to the West Coast it will be even more diluted and therefore not dangerous at all.

It’s not even dangerous to swim off the coast of Fukushima. Buessler et al. figured out how much radiation damage you would get if you doggie paddled about Fukushima (Yes, science has given us radioactive models of human swimmers). It was less than 0.03% of the daily radiation an average Japanese resident receives. Tiny! Hell, the radiation was so small even immediately after the accident scientists did not wear any special equipment to handle the seawater samples (but they did wear detectors just in case). If you want danger, you’re better off licking the dial on an old-school glow in the dark watch.


For the most part the answer is YES. Some fisheries in Japan are still closed because of radioactive contamination. Bottom fish are especially prone to contamination because the fallout collects on the seafloor where they live. Contaminated fish shouldn’t be making it to your grocery store, but I can’t guarantee that so if you are worried just eat fish from somewhere other than Japan.

Fish from the rest of the Pacific are safe. To say it mildly, most fish are kinda lazy. They really don’t travel that far so when you catch a Mahi Mahi off the coast of Hawaii its only going to be as contaminated as the water there, which isn’t very much.Hyperactive fish, such as tuna may be more radioactive than local lazy fish because they migrate so far. As Miriam pointed out in this post, there is a detectable increase of radiation in tuna because they were at one point closer to Fukushima, but the levels are not hazardous.

To alleviate fears that you may be glowing due to ingestion too many visits to your local sushi joint, Fischer et al. figured out exactly how much damaging radiation you would receive from eating a tower of tuna rolls. Seriously. Science is just that awesome. Supermarket tuna hunters would receive 0.9 μSv of radiation, while the outdoors subsistence tuna hunter would receive 4.7 μSv. These values are about the same or a little less than the amount a person receives from natural sources.

To put 0.9 μSv of radiation in perspective check out this awesome graph of radiation by xkcd. You’ll get the same amount of radiation by eating 9 bananas. Monkeys might be doomed, but you are not.


I hope this list of facts has answered most of your questions and convinced you the Pacific and its inhabitants will not be fried by radiation from Fukushima. I certainly feel safe eating sustainable seafood from the Pacific and so should you. If you are still unsure, please feel free to ask questions in the comments section below.


There’s been a lot of discussion in the comments about the contribution from the groundwater leaks. I did some homework and here’s what I came up with. (Also thanks to everyone for the interesting discussions in the comments!)

The ground water leaks are in fact problematic, but what has been released into the ocean is MUCH less than the initial release (although I admit the groundwater itself has extremely high radiation levels).  The estimates from Jota Kanda are that 0.3 TBq per month (1012 Bq) of contaminated groundwater is leaking into the ocean, which has added another 9.6 TBq of radiation into the sea at most.  The initial releases were about 16.2 PBq (1015 Bq), about 1500 times more radiation. With this in mind, the additional radioactivity leak from ground water isn’t a relatively large addition to the ocean.

The models by Behrens and Rossi used initial source functions of 10 PBq and 22 PBq, which is on par with the most recent estimates.  Since their models used a much higher source function, that says to me that this relatively smaller input from groundwater still won’t raise the radioactivity to dangerous levels on the West Coast, Alaska and Hawaii.  Recent observations around Hawaii by Kamenik et al. also suggest that the models may have even overestimated the amount of radiation that hit Hawaii, which is good news.

But there are caveats to this information as well. The leaking groundwater contains strontium and tritium which are more problematic than Cesium-137. But it sounds like strontium accumulates in bones and is only problem if you eat small fish with the bones in, like sardines (and it will only affect sardines caught near Japan since they don’t travel far). I suspect there might be some precedent for understanding the dangers of tritium in seawater from the 20th century nuclear testing in atolls, but I really don’t know. There is also 95 TBq of radioactive cesium is in the sediment around Fukushima, which is still super problematic for bottom dwelling fish and therefore local Japanese Fisheries. Lastly, another source is terrestrial runoff. These numbers haven’t been quantified but they are probably minor because they contain a fraction of the total deposition from atmospheric fallout, which itself was a fraction of what was released into the ocean.

So even with the new groundwater leaks, the available evidence still tells me I can eat fish from the West Coast, Hawaii, and Alaska.


For more in depth articles about radiation from Fukushima in the ocean you should definitely check out some of Marine Chemist’s Posts at Daily Kos. Written by Jay T. Cullen, a Marine Chemist at the University of Victoria, the posts walk you through the most current research on Fukushima Radiation from a variety of sources. I especially recommend his most recent post on Update on Fukushima Radionuclides in the North Pacific and Off the West Coast of North America, were he discusses the recent detection of Fukushima radiation off the coast of Canada. The most recent observations from June 2013 shows the spread of Cesium-137 was on par with the predictions by Rossi et al., but the concentrations are safe and lower than predicted.

  • Chris Graviss

    As a radiologist familiar w these terms, I’m so glad you did this article, so I can just link it to respond to my chicken little friends.

  • Nate

    The Google Earth map appears to be a map showing the spread of plankton and other ocean life that were in the vicinity of Fukushima at the time of the disaster. Again, though, no legend and really no explanation of what the colors even represent. Plus this is based on what COULD happen as of 2012, not what did.

    • CFACT Ed

      That’s the point, Nate, the map is innocent and being used to scare people about radiation which does not relate.

  • lyradd

    Can you comment on this:
    David Suzuki has issued a scary warning about Japan’s Fukushima nuclear plant,
    saying that if it falls in a future earthquake, it’s “bye bye Japan”
    and the entire west coast of North America should be evacuated.

    • kumachanTokyo

      Just ask yourself: if with the meltdown of 3 reactors we had ZERO deaths by radiation and 20 thousand by tsunami and the release of most of the inventory of the 3 reactors, what could happen that would make an even much much much much much much greater release of radiation?
      Besides, I`m curious, did this “person” give the numbers of how much Bq/m3 would arrive in the USA to require an evacuation? And then, did IT went backward to give the numbers of how much needs to be released from Fukushima1 to reach that level in the USA?

      Not to mention that the only building that would have been slightly at risk [reactor 4] saw a huge increase of steel pillars and concrete since april 2011 and it`s now being emptied.

      Btw, if you wonder if there has been any big earthquake after THE ONE, this might show you what we had here and no one cared.
      PUMP UP THE VOLUME and have fun!

      For the weekly updates of sea contamination just ouside the plant:

      • Chew

        “and the release of most of the inventory of the 3 reactors,”

        Only about 4% of the Cs-137 inventory and less than 0.2% of the Sr-90 inventory of the cores has escaped. But your premise is correct. Just because another earthquake and/or tsunami were to hit Fukushima it doesn’t mean the cores will somehow magically release the remainder of their contents and propel it directly at north America.

        Search for “276 PBq” here:

        • kumachanTokyo

          I knew the NISA numbers of 770PBq [but I didn`t look for the separated components] so I thought it was higher, also because what was releaseable released itself. The rest was mixed in the coria with steel, zircalloy and concrete or attached to any available surface.

          But if by your document I see that [276PBq] 40% is in the water filtered by SARRY and KURION, I can only be happy.

          But again, how could we reproduce even the previous leves of release with a super earthquake after 3 years of exponential decreasing of thermal power with the reactors at 18C, 28C and 25C?

          • Chew

            The majority of the NISA estimation was mostly iodine-131.

            The cesium and strontium in the basements isn’t dissolved in the water. It is sitting in the basements as lumps and streamers of corium. The secondary containments were cracked by the earthquake and explosions. Groundwater is leaking into the basements, picking up the cesium that is leeching out of the corium (cesium has a melting point of 28 C), and then making its way to the Pacific. When all the corium cools below 28 C most, if not all, of the radiation will stop escaping.

            There is no way to reproduce the previous levels of release. Corium is a melted mixture of fuel, fuel assembly cladding, and control rods. It can’t go critical.

      • Guest

        This is “this person”, as you called them:

        • kumachanTokyo

          Exactly, you wrote nothing after “:” because you think It is nothing, but IT is worse than nothing, the “IT” is a special category of Kaiju!!
          I also called “this person” IT as you might have noticed.
          And I call IT all the “persons” like Busby that came to Japan to tell us that we were going to die of radiation but if we bought ITs magic pectine pills we would have had no cancer at all.
          Then there are the Gundersen and the Caldicott kaiju: the former IT that said [check ITs own videos please] that reactor 3 had a nuclear explosion that vaporized pool3 [note: the pool 3 is OF COURSE there with all its assemblies]; and the latter IT, at every presentation of ITs unscientific books, shows this picture to say that the world needs to listen to ITs words.

          A friend of mine also contacted the Australian company whose symbol is at the bottom left corner and received confirmation it was fake. Of course the numbers written already meant it was fake, but he asked this confirmation for the chemtrailers “kind”.
          Just to be clear: if those numbers were real, after a few hours the whole West coast would have died within weeks.

          About Gundy that says to be a nuclear operator: IT should know as every 8 y.o. US citizen that a nuclear reactor [or its pool] cannot PHYSICALLY explode like a nuclear bomb.
          OR, if IT is really older than 8 or really studied some physics, IT knows it and IT knows IT is saying poop that a lot of “people” is happy to buy.

          Then there is the worst kaiju of them all, THESUPERDUMB: it is made by billions of cells, each cell weights an average of 60kg and often they clicks buttons on things like this one:

          BTW the petition started from the poops of the previously mentioned Gundy kaiju, and of course immediately bought by the cells listed in the petition.

          BTW, can you tell me the numbers that I requested?
          How many Bq/m3 are needed for a West USA evacuation and therefore how many Bq and in how much time must be released by Fukushima1?

      • Lisa Greene
        (What I pasted previously didn’t post…)

        ‘did IT went backward’????

  • Lisa Greene

    So areas around Chernobyl, after so many years, are NOW too dangerous to eat food from, but the fallout from Fukushima is ok? How stupid do you think we are? (And we won’t even get into WHY they locate these facilities in such dangerous areas to begin with – near coasts, in earthquake zones, etc…)

    • Chew

      The reason there is a difference between the Baltic and Pacific contamination levels is Chernobyl dumped about 14 PBq of Cs-137 into the Baltic Sea and the Baltic Sea has 31,000 less volume than the Pacific.The Baltic is separated from the Atlantic by a narrow strait so very little water in the Baltic makes its way into the Atlantic and vice versa.

    • kumachanTokyo

      What is dangerous around Chernobyl are eventually the small pieces of the reactor that were jettisoned with the graphite explosion.
      Chernobyl didn`t have any Containment Vessel as the democratic countries had at those times and this explains why the total emissions of 3 Japanese reactors are 1/6 of Chernobyl with most of it above and inside the Pacific Ocean, and if it there it`s not in Japan.
      Of course there are some more contaminated zones, but what is dangerous has been restricted beyond reasoning, especially when that crazy woman of the Komiyama set the food limit to 100Bq/kg [USA 1250Bq/kg] with the result that the some of the best European fruit jams have been banned in Japan.

      You put nuclear reactors where there is water to cool them down.
      The problem has never been the earthquake, it was that the power and control lines of the cooling pumps were under water and short circuited, so even when they had the power they couldn`t use them.
      All the list of what happened is very long so I`ll stop here just saying that reactor 6 was able to cool also reactor 5 and Tepco wanted to restart them in the near future but the government said no because people wouldn`t understand.
      Besides the 4 reactors of Fukushima2 will be restarted.
      Do you think that the earthquake did any damage to the Tokyo Skytree which is only 636metres tall?

      Please, don`t ask again “How stupid do you think we are?”.

  • Chew

    When I try to counter the doomsdayers who say Fukushima is an “Extinction Level Event” and it will wipe out all humanity I refer them to this document. See page 8 for a handy table.

    It discusses in detail the amount of radiation dumped into the oceans from nuclear weapons testing, nuclear reprocessing, and all others causes. Fukushima is a minor contributor. When people bring up the fact that Fukushima is still leaking radioactivity into the Pacific, I tell them there is already so much Cs-137 in the Pacific from nuclear weapons testing that 700 times as much Cs-137 decays every day than what Fukushima is adding to it. In other words, the leak from Fukushima would have to be 700 times worse than it is just to maintain the amount of Cs-137 in the Pacific.

    the reactors are leaking. kill the Krill and you Kill life. Krill are all thru out the ocean… all they have to do is swim thru radiation…what eats them dies, etc. and so on.
    stupid, stupid to say this will all be OK. these levels.
    not only are you helping to melt the polar ice caps by heating up the ocean but you are irradiating all the fish and plant life in the ocean – getting in the air is whatever moisture evaporates from the ocean… drops radiation back onto the ground. IT IS A NEVER ENDING CYCLE UNLESS U CONTAIN IT> contain it with cement casing lined with lead all around and under – like a dome!!! do it now!!! expensive. lol… yes, its cheaper to just let the Earth die. Get people to DO IT ‘IF’ they want to Live!
    once u kill the world, you cant buy it back.

    If the radiation is harmless then why are so many US Navy personnel sick from their rescue efforts?

    • Mike O’Brien

      Because most of them aren’t sick from the rescue efforts.

      Actually the only ones who seem to be sick are those frightened and stressed out by radiophobia and lack of knowledge, exacerbated by unscrupulous lawyers looking for a big payday.

    Ok, Fukushima: move on, nothing to see here, it’s all a conspiracy theory, right? Does our Ph.D. have the same opinion of depleted uranium, chemtrails & WiFi? And how’s about those twin towers? Vaccines? Agenda 21? Al Gore’s version of global warming? Our trusted “experts” would never, ever lie to a naive public would they?

  • el laposta

    I have to disagree with you on this article. Too many factors debunk it, especially Stephen Harper having all “radiation detection stations” along the BC coast line turned off until further notice tell me that there is indeed alot to hide in this disaster. Just how bad will it effect us as compared to japan is yet to see…anyone speculating would be foolish. But with underwater currents and storms the radioactive isotopes and or other waste from the rods could impact anyone bordering the pacific ocean. The FDAA already ok’ed the sale of radioactive fish in American stores and I don’t think they would do that unless they knew we were also absorbing waste from the Fukushima disaster! I say we will find out who is correct and who isn’t. Take everything you read with a grain of salt. There are many false flags and war propaganda stories to keep aspiring conspiracy theorists going.

    Kim, could you weigh in on this new hypothesis?

    A Scientific Basis For Destruction Of Ocean Food Chain Via Radiation

  • helennowlin

    While the dilution factor is always considered, dilution is not a solution to pollution (opposite of the meme used by industry when discussing the Clean Water Act). If the release of radiation is continuous and by any one’s account unknown as to duration (no end in sight), dilution will become less important as concentration increases. Radiation is still just about exposure and even “low levels” over a longer period of time still have real consequences on the human body. I think it less important to debate “how little is okay” and talk more about how to stop the release all together. No one seems to have any solutions!
