Japan exported about $600 million worth of aquatic products to China in 2022, making it the biggest market for Japanese exports, with Hong Kong second. Sales to China and Hong Kong accounted for 42% of all Japanese aquatic exports in 2022, according to government data.

    They still can’t come up with anything other than “it’s not safe!” And “you’re so irresponsible”?

    Previous articles on this say the water is less contaminated than that which comes out of some of China’s plants.

    This article: IAEA says 10,000 becquerels per liter is the safe limit. Japan’s output will be 63 per liter.

      China are the ultimate projectionists with this stuff. No transparency for themselves, and very quick to scream blue bloody murder about everyone else.

      And that’s probably the figures China allows the international community to know. If the reports on that are anything like their emissions reports, it’s not even worth the time it took to generate them.

    According to Tepco test results released on Thursday, that water contained about up to 63 becquerels of tritium per litre, below the World Health Organization drinking water limit of 10,000 becquerels per litre. A becquerel is a unit of radioactivity.

    I live in Japan and am not at all worried about this. Maybe local seafood prices will drop. Great for us, but sucks for the fishermen and their families.

    Now, if we could properly build things and not cheap out on the plans so that this doesn’t happen again, that’d be great… (also, more geothermal!)

      Because the color gradient is relative. A large enough banana would also light up. Also exposure time is another factor and this will dissipate very quickly. You can play it safe by abstain of seafood and swimming for a week.

      Radiation levels have decreased since the accident in 2011:

      https://upload.wikimedia.org/wikipedia/commons/0/06/Fukushima_radiation_dose_map_2011-04-29.png

      Note that on Safecast, you can enable “Crosshair” in the hamburger menu to see the actual numbers.

      The central blob area is currently around 5 μSv/hr, so if you live there for a year it’s 44000 μSv, or 44 mSv. The xkcd chart says 100 mSv is the lowest one-year dose clearly linked to increased cancer risk.

          Cancer risk from radiation is not just the absolute amount of exposure, but the duration of the exposure as well. Short high-intensity radiation doses carry higher risk than long, low-intensity doses.

          And 100mSv/yr is a rate, which is greater than 44mSv/yr. After 4 years, you will still have not had the dose needed that is linked with increased cancer risk.

            if you live there for a year it’s 44000 μSv, or 44 mSv

            44 x 3 = 132 which is GREATER than 100

              You can’t compare exposure over 3 years to a limit for one year.

              Radiation damage depends on time period of exposure.

                Though I still wouldn’t want to live there; the area has been evacuated for good reason.

                the graph on the map is μSv/h

                using the crosshairs shows 29.88 μSv/h at the waterfront by the plant

                that is 0.02988 μSv/h = 261.7488 mSv/a

                so not a place I’d want to get food from to say the least

                  That’s on land. Where a whole bunch of various radionuclides have concentrated and remain fixed in place.

                  This “wastewater release” that’s being discussed is the release of low-intensity tritium that will immediately dilute into the whole ocean. You’re comparing apples to moonrocks. Completely different things.

    I know this is a political move by China, the water is (probably) fine. I also know the loss of export is not great for Japan.

    But I hope this means there is a little less intensive fishing going on.

      Japan isnt dumping water so radioactive that it glows in the dark. It is TREATED water. The only isotope that cant be easily removed is Tritium (an isotope of Hydrogen) which is highly diluted and has a relatively short half life meaning that it isnt as persistent as most other radioactive isotopes are.

      TLDR: people are being stupid about this

          Japan is releasing radioactive water into the atmosphere!!!

          The water was already cleaned, but Japan’s historical enemies are pouncing on the chance to throw a fit.

          Tritium is chemically identical to the non-radioactive isotopes of Hydrogen in water. It does differ slightly in its rate of chemical reactions, rate of diffusion and boiling point (i.e T2O, THO etc. Have slightly higher boiling points) but these differences are small and difficult to leverage at the concentrations involved (parts per trillion and lower) and no matter what process you use, the concentration of Tritium wont be zero. And it doesnt need to be. It just needs to be low enough that the radiation exposure is arbitrarily low enough i.e within normal background level deviation. Which given enough dilution by sea water, it is
