Neither would I, eat fish, caught, near drainage outlets, in the inner breakwater of the plant’s port, at the Fukushima Daiichi nuclear power plant.

Evidently, TEPCO attributes the high radioactivity, in fish caught within the plant’s port, to contaminated sediment, from the initial nuclear meltdown, and continued run-off, from rainwater, that flows into the inner breakwater.

Cesium [Cs-134 & Cs-137] concentration, in the sediment, from the seabed, in the inner breakwater, measures more than 100,000 becquerels per kilogram [Bq/kg] Japan’s safety limit, for radiation in general food, is 100 Bq/kg.
The World Health Organization limits it to 500 Bq/kg; based upon the annual maximum permissible effective dose, from radioactive cesium in foods, as 5 millisieverts [5mSv].
The United States limits it to 1,200 Bq/kg.
It is important to bear in mind, that the dietary exposure to radioactive material. can increase as the result of, either, a high concentration, or a high consumption, of contaminated food, and therefore both aspects need consideration.

The outlet of the undersea tunnel, dug to discharge, the Advanced Liquid Processing System [ALPS] treated, and diluted wastewater, is 1 kilometer [1,094 yards] offshore.

TEPCO will start releasing treated, and diluted radioactive wastewater, from Japan’s Fukushima Daiichi nuclear plant, into the Pacific Ocean, as early as this Thursday, August 24/23, if weather and sea conditions permit.

TEPCO plans to release 7,800 tons of treated water, in the 17-day first round of the release, and plans to release 31,200 tons of the treated water, by the end of March 2024, which would empty only 10 tanks at the site.
The water, now amounting to 1.34 million tons, is collected, filtered, and stored in about 1,000 tanks, which fill much of the plant's grounds, and will reach their capacity in early 2024.

I might avoid cruising, in that vicinity, for a while.

It’s hard to have a concept of how much radioactive material this is or how much it might impact the environment, fish, etc.

What about all those open air tests they used to do?

I wonder how this compares.

My country alone has detonated 210 nuclear bombs in the open air. Russia did 219.

109 of these nuclear bombs were set off in Nevada!

No one talks about this radiation/fallout

I’m wondering how this release compares

have we learned nothing from TV...

Isn't this how Gozilla was born?

We though fending off orcas was tough.

Phhft! I just will not moor in Tokyo. All good!

Do you think it is coincidence that the corporation who is venting this water is the Tokyo Electric Power Company (Tepco)? I sense a deeper conspiracy.

[Shrew]

I honestly believe we are talking about two different things here.

The wild caught fish are believed to be contaminated from run-off into the water from the disaster site.

The 'treated' water is reported to not contain these contaminants. They are growing fish in tanks in the plant in the treated water and analyzing the results. There are no issues with the fish being tested in the treated water tanks.

I believe this is a bit of propaganda to point to one issue to argue against the other. That being the planned release of the treated water.

I recently sailed through the Montebello Islands (NW Coast Australia) where the Brits let off a few sizeable nukes in the 50's


Have a Look at:


https://www.montebello.com.au/nuclear-testing/


Lots of signs telling you not to spend more than a couple of hours on the islands that they used and not to take anything off the island.


Beautiful set of islands though with some amazing protected anchorages, although very shallow in a lot of places.



Like how Tepco report the water in Tons Rather than liters - Releasing a Million Tons sounds much better than a Billion liters

Cesium [Cs-134 & Cs-137] concentration, in the sediment, from the seabed, in the inner breakwater, measures more than 100,000 becquerels per kilogram [Bq/kg] Japan’s safety limit, for radiation in general food, is 100 Bq/kg.

Do note that one does not eat the sediment from the seabed, rather, one eats fish who might swim in the water above the seabed. The correlation between sea bed contamination and that in the fish is not discussed in t his quoted statement. Those "shocking" numbers are not relevant to the hazard that may be faced in eating the fish caught inside the breakwater. They well may exceed 100 Bq/kg, but not by the 1000:1 factor suggested in the quote... and have nothing at all to do with the proposed release's effect on oceanic fish

The seabed contamination has been in place for most of the time since the meltdown. The new release of tritiated water, at levels below drinking water standards (prior to dilution in the sea) will not raise the exposure of people eating oceanic fish or swimming in the sea to a discernable or measurable degree, especially at distant islands and seas.
