Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.

Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

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.

No tritium found in fish one month after Fukushima water release (www.japantimes.co.jp)

No detectable amount of tritium has been found in fish samples taken from waters near the crippled Fukushima No. 1 nuclear plant, where the discharge of treated radioactive water into the sea began a month ago, the government said Monday.

Tritium was not detected in the latest sample of two olive flounders caught Sunday, the Fisheries Agency said on its website. The agency has provided almost daily updates since the start of the water release, in a bid to dispel harmful rumors both domestically and internationally about its environmental impact.

The results of the first collected samples were published Aug. 9, before the discharge of treated water from the complex commenced on Aug. 24. The water had been used to cool melted nuclear fuel at the plant but has undergone a treatment process that removes most radionuclides except tritium.

Samples of local fish have been collected at two points within a 5-km radius of the discharge outlet, except during rough weather conditions, with the agency announcing its analysis results on an almost daily basis since Aug. 26.

No tritium was detected in 64 fish, which included flounder and six other species, collected since Aug. 8.

I mean... you could have read the article.

I mean, you are correct, it was not two fish. But is 64 fish some sort of good sample size?
Follow up question: does this type of thing accumulate in small fish and then concentrate in larger and larger fish?

Given the results, it is significant.

Follow up question: does this type of thing accumulate in small fish and then concentrate in larger and larger fish?

No, tritium is treated by organisms just like normal H2O, bioaccumulation is no problem.

I love when people tell on themselves for not knowing a thing about statistics.

Yes, it's more than enough.

[–] [email protected] 3 points 11 months ago

I don't know the answers to those questions, as I am not a nuclear scientist. But the nuclear scientists seem to think so.

In any case, I think those are good questions. Those are the kind of good questions we get when people read the articles.

What number, in specific, would be a sample size you would accept?

But then they wouldn't be able to bitch!
