But some species, such as the Pacific bluefin tuna, can swim long distances and could pick up cesium in their feeding grounds off Japan. However, cesium is a salt taken up by the flesh that will begin to flush out of an exposed fish soon after they enter waters less affected by Fukushima. By the time tuna are caught in the eastern Pacific, cesium levels in their flesh are 10-20 times lower than when they were off Fukushima.
Is there concern about other radionuclides, such as strontium-90?
The continued release of radionuclides from groundwater and leaking tanks at Fukushima nuclear power plants site needs to be watched closely, as the character or mix of radionuclides is changing. One example is the higher levels of strontium-90 contained in groundwater and storage tanks that are leaking into the ocean. Because strontium-90 mimics calcium, it is taken up by and concentrated in bones, where it remains for long periods of time (it has a half-life of 30 years and calcium/strontium is not replaced as quickly in the body as cesium). If leaks of strontium-90 continue, this radionuclide could become a larger concern in small fish such as sardines, which are often eaten whole. So far, however, evidence suggests that levels in fish of strontium-90 remains much lower than that of cesium-137.
No. We don't know that. We know that strontium levels in the waste water were higher than first calculated. We don't know how much has been reaching the ocean since the original release. But the fish don't seem to be showing much. The strontium levels, when high enough to be detected, are far below those of cesium.
As we now know the release of Strontium 90 was huge according to recently released figures from TEPCO despite stating otherwise last year.
No. I did not say it was just the bottom of the sea that was affected, I said that bottom feeders show high concentrations because they are bottom feeders. Yes I said it was localized. Yes, as I have said, cesium from Fukushima was found in bluefin tuna in California. Bluefin tuna migrate from Japan to California. And, like I said, when the tuna leave the Fukushima region the level of contamination decreases. Now, I suppose that if a shark living in California waters ate only contaminated tuna, that could be considered affecting the food chain in California waters. But I wouldn't worry about it too much.
This stuff is getting into the food chain, you said at first it was just the bottom of the sea that was affected, then you said it was localised, now your own source has proven that BlueFin Tuna has traces.
My source does not say it is affecting the food chain a lot further away. It says what I said.
Is the radiation just localised to the sea floor around Fukishima, or localised to the food chain in the immediate area or as your source said affecting the food chain a lot further away?

The "Plume" of Fukushima was, of course, not harmless

By this short conversation I see you do not have a wealth of knowledge in biology, (which is ok this is not an attack) but as someone who does work in medicine and has a considerable amount schooling and practice in the area of cancer, I would get the F out of japan.

Sensationalist much?
Anywhere in Japan? Hokkaido? Shikoku? Kyushu? Okninawa? I guess Koreans should leave Korea too since there are places there that are closer to Fukushima that places in Japan are.
Just how intense to you think the radiation levels are? Are they above background levels everywhere within 1,000 miles of Fukushima? Do you think people should leave Denver because radiation levels are higher there than they are in Iowa?edit on 2/10/2014 by Phage because: (no reason given)

Or there could be another Earthquake that would turn this clean up operation into one of the biggest catastrophes this world has ever seen. Whilst you may assume we are all scaremongering, I believe we all have to have an open mind about the devastation this has caused and could cause if things go wrong.
What news? You mean news like that in the OP? What news has been discredited? You mean the news in your kelp thread?
To me its like TEPCO have an army of shrills working the internet to discredit any news about the incident that has not been sanctioned by them.
No. Because it is going to happen. We know that contamination from Fukushima will arrive in California. We also know it will do so at far below dangerous levels.
What will your views be when the "Kelp Watch 2014" announce they have found Caesium in US kelp directly linked to Fukishima, will you move the goalposts again?
I did not say that.
1) Only the bottom feeders were affected by Radiation
That is true. And once affected some of that sea life leaves the area. And when that sea life leaves the area the level of contamination in that sea life ceases to accumulate. When that sea life leaves the area the level of contamination goes down.
Only Sea Life in the immediate area were affected by Radiation
That was a joke. But if I tried to explain it to you, you wouldn't understand because your confirmation bias would prevent you from doing so.
Sharks could eat Tuna contaminated by radiation of the coast of the US.
You haven't been discussing. You've been throwing out random statements that fly in the face of the known facts.
With this in mind Phage, you are no more clued up to all of this than anyone else, and I am done discussing this subject with you.
