Good news so far and I do emphasize 'so far'. I'll only agree with the '..but we expect the situation will not become worse' when the plant is finally and totally shut down.

Does this study show the levels of radiation in Pacific fish? People don't drink sea water 600 kms off the coast but do eat fish from coastal waters. How about some studies on that?

So the samples taken were well below the levels that are considered harmful? Well no need for this scare mongering research tbh.

From the article:

researchers also sampled fish and plankton

Sounds like this was a pretty thorough sampling of water and edible bits so, so far, this is good news, eh?

These samples were taken 8 months ago, Daiichi has leaked radioactive water since then. So retake those tests and give real-time answers. This is like 42% of those tested in May 2011 in Fukushima had internal radiation exposure, which was 9 months ago. But it is just being published in the news this week.

Me thinks if radiation can be detected in a vast ocean, three months after 3/11, then the original level of contamination must have been 'massive'?

8 ( +11 / -3 )

zichi, more like there is an incredible ability to detect minuscule levels of contamination. A Becquerel is basically one atom decaying per second IIRC.

The America atomic bomb testing above, in it, and below the Pacific released far more radiation than Fukushima, didn't it?

This is what you find when people dump cubic tons upon cubics tons of radioactive water in the ocean and their melteddown power plant is still leaking.

At least it´s probably trust worthy since the research comes from outside of Japan...

NICE!! Sushi and radiation??

Cubic tons??

643 kilometers off Japan in the Pacific Ocean, with water showing readings of up to 1,000 times more than prior levels

In an ocean the size of the Pacific this must have been HUGE contamination without question.

The results are for water samples taken in June

Concealed until February 2012...

article on JT.National Aug.26,2011: Fukushima cesium leaks 'equal 168 Hiroshima bombs. This might be a little bit more than the US bomb testing in the Pacific. More tests should be done.

Does this all mean that skinny dipping in Pacific waters off Japan is still a no-no? One thing for sure, I agree with what Nies says above ... from all that I have seen and heard since last March 11, I believe this is not the full picture. But then ... will we ever get a full picture?

The atomic bomb testing from the late 1940's onwards were more than 100 greater than the ones used against Japan.

Looks like the only way to be safe is to avoid the Pacific Ocean completely!

How wonderful. Is there anything that would make the world understand that redioactive plants are a lose-lose situation? How many fish now are contaminated with this???

And this is big news now? People, at least check out this headline from April last year. Vancouver is about 7200 km away from Fukushima.

Talk about major shitsurei to much of the world. I'm not seeing any deep bowing or jumping from high places so far..

Daichi power plant is still putting out radioactive water into the ocean and land on a daily basis. Does anyone have a link to show how much?

Does this study show the levels of radiation in Pacific fish? People don't drink sea water 600 kms off the coast but do eat fish from coastal waters. How about some studies on that?

How about comparative samples taken 3, 6 or 12 months after the tsunami at the same locations? Knowing what it was like 3 months after the disaster is not as useful as knowing how things have changed over time. Also - what kinds of fish were sampled? Concentrations of contaminants will be higher in top predators like Tuna, Swordfish and Shark.

As research this is laudable but as everyone is pointing out there is still ongoing contamination. Not only that but as radioactivity concentrates in living organisms , it would be logical to assume that present readings would be higher.

The incident on March 11th at Daiichi and it's ongoing saga is one of if not the most critically important happenings in the world right now. There needs to be more tests for everything and everyone concerned. Foodstuff, land, air, sea, people, forest.etc. you name it and it needs periodic tests.

@kurisupisu:

Not necessarily higher. The dilution process goes on continuously. There will be an equilibrium distribution in the far future if you wait long enough (I guess at that point most of the cesium would have already decayed), but in principle there is a need for constant monitoring at many different locations in the ocean, since the local distribution is volatile.

@Zichi:

In a nuclear explosion, you have a massive neutron flux. Thus, the daughter products of nuclear decay are in general more neutron rich and have in general shorter half-lives. Thus, you get a high spike in activity which decreases quickly.

As has been said here, the release continues perpetually. Nevertheless, the release rate has been decreased from the initial releases by a factor 10 millions since the beginning until summer (I think the end of July or so). Thus, you'd have to wait a mighty long time to get an amount of further release which is comparable with what TEPCO already dumped into the ocean. We are comparing here the triple of a time span to the 10 million fold radioactive release. The overall contamination will not change dramatically anymore, whereas the local contamination is still volatile. Despite of how these previous sentences might sound, I by no means consider the ongoing release as acceptable or unavoidable.

The sea bed next to the Fukushima NPP, is contaminated with very high levels of cesium from both the leak of contaminated water and from the explosions in the reactors .

TEPCO's answer is to cover 70,000 sq meters of the sea bed with concrete, 60 cms thick. The work will begin at the end of this month, and should be complete within four months.

Is this a first? Covering sea beds with concrete?

Make a movie called, "Ocean 131"...the sequel...

0 ( +0 / -0 )

This is just the beginning. Worse than Chernobyl? Time will tell. And this is just the beginning.

This disaster, which our children's children will inherit, is absolute proof that nuclear power is the worst possible way to boil water.
