Japan said on Tuesday it will start releasing into the sea more than 1 million metric tons of treated radioactive water from the wrecked Fukushima nuclear power plant on Aug. 24, going ahead with a plan heavily criticised by China.
It’s a lot of tritium, versus baseline. Continental precipitation tritium is ~10 TU, the maximum ocean surface readings at high runoff locations (elevation runoff, not industrial) are ~2TU, most ocean readings are ~0.25 TU.
1 TU = 0.15 Bql
So this is >125x what is found in uncontimanated freshwater, or >625x what is found in the worst measured ocean runoff locations, or ~5,000x average ocean readings, and >8,000x Southern Ocean surface waters.
Again, the main opponent here is China, who allegedly puts way more tritium into the water than Japan. So it’s a case of the pot calling the kettle black.
South Korea doesn’t seem to have an issue with it, and S. Korea is also an economic rival of Japan. But maybe S. Korea is less affected because of currents, IDK.
So we should definitely study the effects, and I’m sure there are plenty of interested parties doing just that, but we shouldn’t be going on the attack until there’s actual data pointing out harm. Right now there’s mostly FUD, and until that becomes fact (i.e. an adjustment to WHO or a similar body’s standards), I think we should monitor it closely but go forward with it.

This is also after all the atomic bomb tests, that added most of the tritium in the environment today. here is a cool paper about using tritium to measure ocean currents that I got most of my data from.
It may be safe for humans, but I don’t think you can handwave away potential dangers to aquatic life based off that.
