Tritium density exceeded the safety limit at one of the bypass wells one day after they discharged 1,600 t to the sea

Tepco announced Tritium density exceeded their desired safety limit at one of the bypass wells.


The reading was 1,700,000 Bq/m3, which exceeds the desired level by 200,000 Bq/m3. This is the highest level from this bypass well.

This sample was taken on 6/9/2014. Tepco had discharged 1,563 t of contaminated bypass ground water to the sea on 6/8/2014.



You read this now because we’ve been surviving until today.

  1. the are thousands of toxic radionuclides flowing out of the reactors, why the regular focus on tritium?

    1. Tritium (HTO, DTO, T2O) is a Beta (β) Emitter. Tritium, in its three most common forms occurs in nature, at a very low level, on Planet Earth. The β particle, or β wave if you prefer, is a high energy (speed) electron. β particles impact (hit) water molecules and metals which result in a Gamma (Γ) ray, or X-Ray or traveling electromagnetic wave or high frequency light waves (if you prefer). Other Beta (β) emitters such as radiocesium and radiostrontium have similar characteristics; at various energy levels.

      These are not the sorts of activities which should be artificially increased in the hearts and minds of children, the unborn, young women; or people, animals or within plants and bacteria.

        Well, they didn’t advise them to stay out of the rain even once over the last 3 years plus, so is this really surprising? Resident populations are literally a liability to governance world-wide – a liability most governments are doing their damnedest to reduce as much as possible.

        http ://

  2. A continuous X-Ray

    The Fukushima groundwateris HIGHLY CONTAMINATED with β emitters. Thus the water storage tanks and water pipes are emitting high levels of X-Rays or Gamma (Γ) Rays if you prefer.

    The very ground at Fukushima is emitting dangerous X-Ray levels. The Japanese have been forced to place metal radiation shields on the ground to reduce the danger level to the workers.

    The Earth and Water at Fukushima are unnatural and quite deadly.

      1. Seriously,

        The above are fairly simple, factual statements, which have been often covered.

        Is Niall the Team Nuke Puke, actually advocating radiation hormesis, along with Ann Coulter and Dr. Brainwasher? Or denying the need for personnel radiation safety measures at the the Fukushima Daiichi Nuclear Power station? Or, both?

        It is not always clear what Niall the moron is trying to communicate.

          1. He appears to be appropriately framing the phenomenon of “braking radiation” or Bremsstrahlung.

            It is surprising that you missed the obvious holes in his previous statement. WTF?

  3. Not that you have to become an expert but from Wikipedia:
    “…Tritium is an uncommon product of the nuclear fission of uranium-235, plutonium-239, and uranium-233, with a production of about one atom per each 10,000 fissions.[7][8] The release or recovery of tritium needs to be considered in the operation of nuclear reactors, especially in the reprocessing of nuclear fuels and in the storage of spent nuclear fuel. The production of tritium is not a goal, but rather a side-effect…”

    So the question arises as to where all this (rare) Tritium is coming from. Just another minor detail when it comes to meltdowns,forgetting Tritium can pass through anything except the densest of materials ex. gold, it combines with oxygen to become tritiated water and is a carcinogen. The half life is still a bit vague.

    Like Plutonium when only a handful could be found on earth before man began fracturing atoms, it is now measured is hundreds of tons and still increasing.

    1. Tritium is not a common fission product but it is copiously produced by neutron capture on the deuterium in the cooling water.

      1. Quote: “According to Edwards, the CANDU reactor in Gentilly, Quebec annually releases 200 trillion Becquerel of radioactive Tritium into the environment. And, according th Edwards, this number is increasing each year.

        Tritium is a low-energy beta emitter, meaning that it is relatively harmless externally. It is often used on modern luminous watch dials and emergency exit signs. But, consumed internally tritium, like most radioactive materials, can be quite dangerous. Tritium is an issue with all nuclear reactors- but, tritium releases are particularly problematic with the CANDU design.”

        quoted from: http ://

        Of course, it is not simply the radioactivity of tritiated water that makes it harmful to biology but it’s differing electrochemical properties from regular water.

        1. CANDU reactors use heavy water with enhanced deuterium content as their coolant. (It improves the neutron economy of the reactor.) Therefore they produce more tritium per kW/hr than regular light water reactors. They can also use normal uranium with U235 content 0f 0.7% which is an advantage over regular reactors that need to have the U235 content enriched to 4% before they can sustain a chain reaction.

          1. Title: “Quebec to shut down its only nuclear reactor”

            Quote: “The government of outgoing Premier Jean Charest decided in 2008 to rebuild the Gentilly-2 nuclear plant at a cost of about $2 billion, but stopped work after the Fukushima disaster in Japan in 2011.”

            Vive le Québec, libre de l’énergie nucléaire!

      2. I am curious to know the origins of deuterium.
        Searching thusfar has been unsatisfactory.
        Can you please tell me where to go?

        1. Huh.

          Try “wiki deuterium” also “wiki nucleosynthesis”.

          Most deuterium in the universe was produced during the big bang. It is also produced in reactors when a hydrogen atom in the cooling water captures a neutron.

          1. Ah, so protium does have a neutron cross-section sufficient for neutron capture.

            So some deuterium could have been produced at the Fuku Daichi site, at least at some point over the last three plus years.

            Will take your advise and research further, though i will start with Dr. Edwards’ wonderful site (linked in username). Thank you.

            1. Will also “wiki nucleosynthesis”.
              The oldest of galaxies (such as Segue 1) have the least amount of heavy metals.

              There at least one can imagine a world without “nukular” power or “nukular” weapons.

  4. folks, many thanks for the answers, but there are thousands of rare radionuclides produced by Fukushima.
    There are all harmful and rare.
    Why the focus on tritium?

      1. Well, Mochizuki-san did do a nice debunk on the alleged SFP #4 fire within the last month or so. Would you like to be quoted again?

        Title: “NO evidence to support the rumor of “fire on reactor4″”

        Quote of Niall: “Well done Iori-san.”

        . quoted from: http ://

        How am i doing so far?

        Where is your “rational focus”?
        It is like reading the postings of a “loose cannon”; one that even goes off on it’s own, though they still “honored” you despite poor representation.

        Does anyone really know what to expect from any consecutive reply by Niall?

        Just how do you represent “irrational exuberance” & increasing epi/genetic entropy in our shared atmospheric/hydrologic systems with a straight face anyway?

        1. I was being sarcastic, dumbass. Seen any bears rolling down hills lately, cos i dont have a detector.

    1. Do you object to the occasional tritium post?

      The Fukushima SIGNATURE radio-isotope is Cesium-134. The Cesium-134 released into the Pacific Ocean from Fukushima, was of the same order of magnitude as the TOTAL radio-cesium content of the Pacific. The Fukushima Cesium-137 release was also about the same. Fukushima roughly tripled the TOTAL Pacific radiocesium contamination. And it is still flowing into the Pacific Ocean today.

      The Fukushima sourced Strontium-90 contamination is similarly disastrous.

      Perhaps in a few days, the subject of Nobel gases or Americium and Plutonium will be the topic.

      There are no shortages of subjects, in the Fukushima disaster.

        1. … not to mention other forms of geoengineering, planned or otherwise (to which you might have a front-row seat, Mr. Duff).

      1. I’m aglow awaiting the occasional tritium (tritiated water) post!

        Is it true that there is no official limit for tritiated water in Japanese drinking water?

        7000 Bq/l is the limit here in Candu, IIRC.

        Of course, the radioactivity relating to internal contamination is not the only process by which tritiated water causes biology harm.

        1. Tritium TEDE is 0.0000169 microSv/Bq

          So if you drink 2 liter of 7000 Bq/L water every day for a year you would get an additional

          7000 Bq/L * 2 L * 365 days * 0.0000169 microSv/Bq = 86 microSv/year of radiation.

          You can compare that to the

          280 microSv/year you get from naturally occurring nuclides in your food and water (K40 and C14)
          210 microSv/year you get from nuclides in your environment and
          330 microSv/year you get from cosmic rays

          Europe sets a drinking water standard for tritium of 100 Bq/L which would only give an addition 1 microSv/year which seems overly conservative to me.

          and note 7000 Bq/L = 7,000,000 Bq/m3

          so the levels that are being discharged would pose no significant health threat even if you were drinking it straight.

          1. 100 Bq/kg is Europe’s limit, 7000 Bq/l is the limit here in Canada, and Japan appears to have no limit for Tritium in it’s drinking water.

            Europeans (et al) have properly reckognized that tritiated water does not harm via radioactive decay alone. There are important chemical differnces between tritiated, deuteriated, and regular water that do have negative consequences for biology.

            Even the differences in density can explain why so much tritium is found deeper than 20 meters than it is near the surface.

      2. not object at all. Just want to know why TEPCO releases so much info about it and this is relayed to us.
        What is more than special about it?

        1. They release info because if they didn’t they would be accused of trying to cover something up.

  5. More Tritium if you please.

    Perhaps we should focus MORE on the dangers of tritium contamination. It is often useful to OBSERVE the reactions of the adversary.

    Quite often, they project their weaknesses and concerns, in their remonstrances, arguments and tirades. That which the nuclear industry trivializes, is often critical. Certainly, there have been many tritium releases in the USA, Canada & Europe.

    More Tritium Reporting is in order.

    1. Quote: “Nuclear Regulator Allows ʻTritium Unlimitedʼ
      by Gordon Edwards, Ph.D., President of CCNR, September 15 2012

      On February 1, 2010, a tritium light factory (SSI) located at the Peterborough
      Airport released 147 trillion becquerels of tritium to the atmosphere in about 5 minutes. This did not become public knowledge until 2012.

      Instead of being alarmed and galvanized by this enormous radioactive release, the Canadian Nuclear Safety Commission staff trivialized the event by saying that the
      release was far below the “derived release limit” of 34 MILLION trillion becquerels per year — a limit so astronomical in size that it is literally absurd.

      In fact the sudden release of 147 trillion becquerels of tritium was about 30% of the maximum allowed annual release according to the LICENCED release limit of 500 trillion becquerels per year — a very permissive limit indeed! But that limit is 68,000 times LESS than the “derived release limit”

      Are you confused? Well, congratulations!

      That’s exactly what the nuclear establishment seems to be seeking to accomplish:
      confusion to the point of mystification.”

      . quoted from: http ://

      1. There’s 5 million trillion kilograms of atmosphere on earth. If you’re going to understand this stuff you’d better get used to dealing with large numbers.

        At sea level a cubic meter of atmosphere weighs about a kilogram. So once that release of 147 trillion Bq is mixed with the atmosphere you’ll have 2.9 microBq/m3 which will have little to no effect on public health.

        Now if you ingested 147 trillion Bq of tritium you would die of acute radiation poisoning in short order.

        So the question then becomes how fast will that release disperse and how much is someone close to the plant likely to absorb. Since hydrogen gas is lighter than air it’s not going to hang around the ground where someone could be exposed.

        1. Quote: “Since hydrogen gas is lighter than air it’s not going to hang around the ground where someone could be exposed.”

          So you do agree then that protium/deuterium/tritium gas can be an effective ozone-depleting substance then?

          Radioactive decay is not the only property of tritium that makes it harmful to biology.

          1. Sure.

            I’m not an atmospheric chemist so I’m not going to try to estimate how big an effect it will be compared to other ozone depleters.

        2. “if you ingested 147 trillion Bq of tritium”

          … if an open-casket funeral were held, they might not need any emergency lighting to point out the nearest EXIT.
          And, actually, as a gas, death would most likely be officially by asphyxiation, neh?

          Radioactive decay is not the only means by which tritium can negatively affect biology.

          1. “And, actually, as a gas, death would most likely be officially by asphyxiation, neh?”

            Probably not. 147 trillion Bq is 0.4 gm. Double that for HT gas and it’s 1gm or 1 liter of volume.

  6. Tritium is much more closely regulated in Europe than in the USA and Canada.

    We can infer concealed danger, from this and the continuing ‘Team Nuke’ pattern of deception.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
