Japan started releasing treated radioactive water from the wrecked Fukushima nuclear power plant into the Pacific Ocean on Thursday, a polarising move that prompted China to announce an immediate blanket ban on all aquatic products from Japan.

China is “highly concerned about the risk of radioactive contamination brought by… Japan’s food and agricultural products,” the customs bureau said in a statement.

The Japanese government signed off on the plan two years ago and it was given a green light by the U.N. nuclear watchdog last month. The discharge is a key step in decommissioning the Fukushima Daiichi plant after it was destroyed by a tsunami in 2011.

    The water is less radioactive than humans, the ban is purely political and in no way safety related

      Fish accumulate toxins and heavy metals as you move up the food chain. This is well-known.

      Even though swordfish swim in waters that have perfectly safe mercury concentrations, eating swordfish everyday is inadvisable because of their high mercury contents.

        That’s a great point, however it ignores just one inconvenient fact:

        Tritiated water cannot bio-accumulate in the environment

              US psyops trying to gaslight the content of the article. There are trace elements of other contaminants… Of unknown concentration, and we have to take TEPCO’s word that it’s “like, totally safe man, just like our nuclear reactors”

                There’s 4.5 billion tons of uranium dissolved in the ocean, I’m pretty sure a couple milligrams of trace elements isn’t going to change anything.

                  Oh, because that’s a great answer to a localized ban.

                  Guess what? Most of the volume of the ocean isn’t chilling in Japanese territorial waters.

              But he does think that non-tritium contaminates missed by the ALPS system could build up over time near the shore.

              “Nearshore in Japan could be affected in the long term because of accumulation of non-tritium forms of radioactivity,” he says. That could ultimately hurt fisheries in the area.

                  Ah yes, because the only danger of nuclear meltdown industrial wastewater is tritium.

                  One big concern is that the ALPS system is imperfect: it supposedly removes other radioactive contaminants to within legal limits, but those legal limits ARE higher than that of seawater. The ALPS has also been custom-designed for this project: it is a bespoke system that hasn’t been tested in production.

                  Plus, this is coming from the same private entity that mismanaged the Fukushima plant enough to cause the disaster… How much faith do you have in them to not fuck up again? Tepco’s optimizing for their bottom line, not for what’s best for society.

            I recommend reading the article again. They got anything but the tritium out of the water. Which is comparable easy to accomplish, and also important. The remaining tritium is as harmless as radioactive things can get in the first place.

            A radiation scientist here reminded people of those radium-based glow-in-the-dark wrist watches, and compared the radiation caused by this wastewater release to adding about 70 to 80 of those watches to the pacific ocean.

    Sure. Because Chinese food regulations are notoriously tight and the populace is so protected from contaminated foods.

    I’m guessing this has more to do with fishing rights in the South China Sea and this is just convenient for them.

          Unfortunately that shows that it’s probably a bad sample, the paper calls it out at the end. The curious issue here is they found it in Jan 2020 but them March of 2019…but nothing in between. So the odds of the march sample being a false positive are pretty high.

          The medical community is pretty well positive it originally came from the Wuhan lab, that was found to be selling their used animals on the wet market, I don’t think I’ve seen anything for a while now say different. Unless it’s a Chinese source which doesn’t want to take responsibility at all.

    China having the audacity to take a stance on this while taishan has been leaking since 2020 is easily the funniest fucking thing I’ve seen all year. For anyone uneducated in the matter of radiochemistry, the water from fukushima is more well treated than the water that comes out of Canadian or American reactors from regular use.

    At the very least people should be forced to read the IAEA report before being allowed an opinion on something they clearly do not understand, especially when disingenuous garbage information is being spread around by malicious actors and bots.

      This is standard geopolitical bullshit. They wanted to ban seafood imports from Japan and this is a good excuse. Radiation is easily detected. It’s not like they would be taking some unpredictable , unknowable risk here. The radiation contamination risk isn’t the point at all.

      It’s the same as the international beef market. A cow falls over in Alberta somewhere and suddenly 5 countries ban Canadian beef imports across the board. The reason they give is “because of the possibility of mad cow” but the truth is they’re constantly looking for an excuse to issue protectionist measures .

    Let them worry about minute amounts of tritium in the ocean - it is political hubhub, nothing more. The tritium is less pollution and will vanish faster than microplastics in the seas.

      No poison acts like a boolean value, it’s all about dosage and exposure. The idea that fish closer to the contamination site will be more contaminated than fish farther away seems pretty obvious.

      If I stand next to you while you fart, I will smell more than if I stand a kilometer away.

      Mind you, I’m not saying China is right, it’s obviously a political ploy. But I disagree with your logic.

              OK, I’m not sure if you’re arguing with me, or really aggressively and antagonistically agreeing with me.

              I’m arguing against your initial point. I don’t think I’m being “really aggressive and antagonistic”.

              I’ve been through graduate psychopharmacology and know all about toxicity. I think you should consider reading my post, again, in a different light, and maybe terminating this conversation.

              Please explain to me which light I should read your post in. It seems to me that you said: even if China were right, their fish would be just as contaminated as Japans fish, as you wrote:

              Even if your premise was anything but political-- and it’s not-- how would your seafood be any better?

              This is obviously wrong if you understand that toxicity is based on exposure and dosage, since Japans fish would be closer to the point where contaminated water is poured out.

              Later you wrote:

              They’re not fishing from the damn power plant.

              Nobody stated this. However it’s not like “distance to powerplant” is a boolean value (in powerplant/not in powerplant). It’s a distance. Japans fish are closer to the point where the contaminated water is poured than Chinas fish are. So why is your retort only that they’re not fishing from the power plant?

              How else am I supposed to read your comments?

      This is tritiated water, that is water with tritium (aka hydrogen-3 , regular hydrogen [a proton] with two additional neutrons) in place of regular hydrogen.

      Tritium has a half life of 12 years. The incident was in 2011, so there’s been one half life already. The remaining tritium will be diluted with seawater and naturally decay over a few more half lives until it’s indistinguishable from background radiation.

      Edit: the decay product is helium and an electron +and strictly speaking a neutrino, but those don’t really interact with much so we can ignore it). Nothing to really worry about!

      My understanding is that they can chemically remove damn near everything except the tritium. It’s because the tritium hydrogen atoms aren’t in the place of regular hydrogen in H2O.

      So essentially they can’t filter the water out of the water, if that makes sense.

      Which shows one of two things: Either you were fast asleep in physics in school, or your physics teacher was an idiot.

      All that tritium water release is about as “dangerous” as losing 70-80 glow-in-the-dark wristwatches in the ocean. And in comparison to the microplastics issues, the Fukushima water is laughably harmless.
