Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Good, it's about time. Tritiated water just isn't dangerous. The ocean naturally contains billions of tons of URANIUM. A few kilograms of short lived tritium isn't going to matter at all.

Finally someone who understands it's not as scary as news want it to sound like.

[–] finestnothing@lemmy.world 5 points 1 year ago

Better yet, the water they're releasing has less tritium in it than average ocean water, so releasing it will actually be an improvement for the ocean (190 vs avg of 500 of some unit)

Wait I get that the ocean is gigantic but billions of tons?

[–] Cleverdawny@lemm.ee 13 points 1 year ago

Yep. Best estimate I have seen is 4.5 billion tons of uranium. Course, most of the natural radioactivity of our ocean is from potassium, actually. But either way, natural levels of radioactivity will not change.

4 billion tons at 3 ppb... It's so much water, don't try to drink it either.

For anyone curious:

From Wikipedia:

The total mass of Earth's hydrosphere is about 1.4 × 10^18 tonnes, which is about 0.023% of Earth's total mass.

This is what I’ve heard too. It’s really no big deal. Concerned local fishermen are probably just not introduced to the physics of this. In general, humans tend to worry a bit more about radioactivity than necessary. This in particular will be diluted into basically nothing. The only real problem is the PR work that lies ahead for them. In practice, their people should probably be more concerned about constantly dying early from pollution and protest more about that.
