I kinda feel like the size of the full ocean isn’t relevant to the effects of acute radiation exposure to the fish immediately in the area around the dumping zone. I’m not saying the whole ocean will be irradiated, or even the entirety of Japanese seas. But there will definitively be a section of the ocean, that, at least for the duration of the dumping of the (300 million gallons was it?) irradiated water will be exposed to significantly higher than acceptable amounts of radiation.
What I’m trying to figure out is not if this zone will exist, it will, period. What I’m trying to figure out is how big will that zone be, and will iT persist after dumping has completed? It could be just the 30ft immediately surrounding the outlet, or it could be 30mi, but I can’t seem to find any estimates, everyone is using the whole ocean as their metric, when I’m talking about the immediate area around the dumping area.
