This is one of those lurking issues that is a slow motion disasters. How soon, and it is a when, not if, will commercial fishing be stopped in the Pacific? 2 years, 5 years? There is already reported elevation in Pacific fisheries and waters along west coast and up to Alaska. This is very scary and more effort should be put in stopping the drainage into the Pacific. I bet 99% of Americans don’t realize the reactors are still dumping radiation into the ocean.
Embrittlement of metal generally requires displacement damage and gamma radiation is not terribly efficient for doing that. You generally need high-energy neutrons, and you aren’t going to have those in any kind of fuel residue, at least not in significant quantities. Gammas cause ionization and eventually heat, and can damage junction devices, but the metal itself is not likely to be degraded by exposure to gamma sources.
Oh yeah no harm could come from setting off a nuke. doofus
“IATDS (In after the doomsayers) who believe everything put out by the NOAA agendanistas.”
i’m guessing NOAA wanted to promote the idea that climate change and global warming were responsible for the below average fish catch. now that the Fukushima disaster may be related this may upset their plea for more money to offset the catastrophic effects of climate change.
let’s hope that Wilbur Ross, Dept of Commerce Secretary Designate, becomes informed about the data manipulation that NOAA has been caught doing in order to support Obama’s climate change agenda.
I remember from training that 200-300 roentgens would be 50% deadly and 400 was 90-100%...
The oceans mix fairly well over time, but how the radiating isotopes would sort out is hard to tell.
We do not know if they are dissolved, or in particulates.
There is a tremendous amount that is not known.
We do know that the radioactive increase on the west coast is quite small.
“Out of the 110 new contaminated samples detected off the US west coast, the most radioactive was collected around 2,500 km off the coast of San Francisco. It contained 11 Becquerel’s per cubic metre of seawater – which is equivalent to 50 percent higher cesium levels than other samples collected in this part of the ocean so far.
Buesseler’s research has also shown that Fukushima is still leaking radioactive material into the ocean in Japan, with the levels off the Japanese coast between 10 to 100 times higher than the levels off the US West Coast today.
“Levels today off Japan are thousands of times lower than during the peak releases in 2011,” said Buesseler. “That said, finding values that are still elevated off Fukushima confirms that there is continued release from the plant.”
Isotopes with short half-lives give off lots of radiation, but drop off very quickly, so the danger passes quickly.
Isotopes with long half-lives give off tiny amounts of radiation, but last for a long time. That is most of background radiation.
Researchers find high cesium in some Pacific plankton

Scientists said Tuesday they have detected radioactive cesium from the Fukushima No. 1 nuclear plant in plankton collected from all 10 points in the Pacific they checked, with the highest levels at around 25 degrees north latitude and 150 degrees west longitude.
This dispersion model only shows radiation levels in seawater.
What is there to be said about radiation in the rain water as a result of evaporation?
“The oceans mix fairly well over time, but how the radiating isotopes would sort out is hard to tell.
We do not know if they are dissolved, or in particulates.”
If in particulate form, then it could be deadly eating seafood contaminated by it.
Yes, and no level was safe. I was a reactor operator in the Navy and remember the training very clearly.i am not anti-nuclear power but if they cannot handle disasters then they should shut them down. I don’t trust the government to tell the truth. Bothersome and curiously worrying that most of the US monitoring went offline, publicly, when the radiation was initially due here. Lots of US Navy personnel got cancer from Japanese area deployment, rescue, and recovery. Wonder what over stats are for cancers since?

with the highest levels at around 25 degrees north latitude and 150 degrees west longitude.
What the article does not say is that the “highest levels” are only 50% higher than the background radiation.
We haven’t been able to detect ill effects at 10 times that level of background radiation on the continents, and from Cesium 134, that level drops in half every two years.
Sorry dude, that is one stupid-butt solution, and you have no concept of what you speak.
What was the MPD (max permissible dosage)?
Wasn’t it 10 rems??? Something like that...
A fine piece of journalism. Comparing Fukushima to TMI and Chernobyl is a scare tactic. Typical. Dishonest writing like this is not to be believed. It is merely advocacy journalism.
Is this "writer" actually surprised that an accident in a reactor 50 feet from the ocean puts more radiation into the ocean than ones dozens or hundreds of miles from salt water?
I remember we had to wear those pocket dosimeters any time we were in a nuke space....
They will also need very clever mechanical designs that allow field replacement of major working elements by remote-controlled repair robots.
Think of a remote-controlled earth mover or front loader that is fueled, maintained and serviced by remote-controlled mechanics.
None of these machines will ever leave their work areas until they are removed by remote-controlled disposal vehicles, and transported to a dump zone.
It will be a very complex mechanical ecosystem requiring very smart people to build and operate it over many decades.
One of the world’s most popular dive sites is Bikini Atoll, for all the sunken warships there. They were once highly radioactive. Not any more; the radioactivity has been washed away in the vastness of the Pacific Ocean.
