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

[-] Aliendelarge@lemmy.world 29 points 1 year ago

A government using "safety" for political reasons? Never seen thst before.

Well China should ban their own fish, since they release waste tritium themselves. https://en.m.wikipedia.org/wiki/Tritium

China has entire towns that are toxic wastelands. This is just a political statement, probably their usual brainwashing of self.

[-] Treczoks@lemmy.world 4 points 1 year ago

Or just compare the dangers of microplastic, of which China is quite a source. The microplastic will be around long after (most of) the tritium is long gone.

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.

Wasn't that virus issue that we just had and continued to have caused from wet markets over there?....or no that was the Japanese who caused it right?

/S if no one got the joke

Does that mean China will stop fishing in those waters too?

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.

[-] Sodis@feddit.de 23 points 1 year ago

China release more tritium in the sea than what is planned at Fukushima, so yeah...

[-] Treczoks@lemmy.world 8 points 1 year ago

And they release way more plastics in the sea, which is way more critical than the tritium.

[-] Rand0mA@lemmy.world 4 points 1 year ago

Just a question here but do you treat radioactive ☢️ water? I thought once it was radioactive that's it for like 100000 years

[-] Kangie@lemmy.srcfiles.zip 27 points 1 year ago* (last edited 1 year ago)

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.
