Tests of seawater near Japan’s Fukushima nuclear power plant have not detected any radioactivity, the environment ministry said on Sunday (Aug 27), days after authorities began discharging into the sea treated water used to cool damaged reactors.

Japan started releasing water from the wrecked Fukushima plant into the Pacific Ocean on Thursday, sparking protests within Japan and neighbouring countries, in particular China, which banned aquatic product imports from Japan.

Japan and scientific organisations say the water is safe after being filtered to remove most radioactive elements except for tritium, a radioactive isotope of hydrogen.

    As totally expected.

    I’m no scientist, but even I know the basics of how it works. And then there’s the actual scientists…

    Wanna bet most people making a scene out of it don’t even use sunscreen?

    The sun pumps out some amazing stuff. It happens to be the OG nuclear reactor.

      Sunscreen doesn’t protect from gamma rays, does it? It’s not really fair to compare radioactivity with sunshine.

    The elites dont want you to know this but the Godzillas in the ocean are free you can take them home I have 458 Godzillas

    On one hand it’s weird how people are so upset about this, on the other these morons were talking about radioactive fallout hitting the US right after the tsunami hit. They aren’t the brightest bulbs.

      Because no human activity could ever have effects that accumulate at the macro scale. All that plastic has been successfully diluted and SO2, CO, CFCs and CO2 are all harmless once released.

        (I mean, we’re talking about radioactive water from one nuclear power plant. I’m pretty sure the adage applies in this case.)

    Did they test the sea floor? Some of it sinks. The concern isn’t radioactive seawater, it’s seabed accumulation working its way into the food chain

      The sea floor will have a lot of thorium and uranium, because every inch of the ocean floor does. This is because uranium oxide is water-soluble, and billions of years of erosion have led to the oceans being full of the stuff.

      Thorium does not have a natural water-soluble oxide, but can end up in suspension, to participate out to the ocean floor.

      Now, we’re not actually talking about uranium or thorium in this water discharge, instead we’re talking about deuterium and tritium, both of with can naturally be found in seawater, but natural tritium is vanishingly rare. It’s usually created via cosmic ray, and has a half life of 12 years.

      Anyway, the point is, all this radioactive material, both natural, and discharge, will be so diluted that it’s not an issue.
