Title: Assessment and characterization of radionuclide concentrations from
the Fukushima Reactor release in the plankton and nekton communities of the
Northern California Current
Delvan Neville (Oregon St. Univ.), Richard D. Brodeur (NOAA), A. Jason
Phillips (OSU) and Kathryn Higley (OSU)
The incident at the Fukushima Daiichi nuclear plant released a substantial
radioactive contamination into the environment. With the predominant wind and
current flow in this part of the North Pacific, these radionuclides will gradually spread
to the US West Coast waters after a suitable period of time,
with the possibility of
affecting food quality throughout the food web (including
humans). In addition to the passive transport by currents and
winds, the migratory pathways of large pelagic fish extend from Japan to the
Northern California Current. These organisms can serve as transport vectors for
these nuclides, especially given their capacity to concentrate radionuclides
from surrounding waters and prey. [...] By predicting the radio-biologic stress
(if any) for a managed species as more Fukushima-related radionuclides are
uptaken, appropriate action may
be taken before significant population effects have occurred.
Determination of natural background concentrations and high quality transport
models produced from these data also aid in management in the event of a future
accidental release, and in regulating safe activity releases.
Oregon State University Press Release, Oct. 24, 2012:
[...] Phillips spent this summer collecting more fish at sea, off Oregon and
Washington, as well as from scientists, fishermen and other sources along the
West Coast. [...] As more fish were tested, the results were consistent with the
initial findings: No Cs-134 in fish caught before the disaster, but traces of
the isotope in a significant number of fish caught since. “This is what we’ve
seen after testing about 70 pounds of tuna,” Neville said.
[...]
No mention of the actual cesium levels detected in the tuna, only that it’s
safe to eat.

CORVALLIS, Ore. – Samples of albacore tuna caught off the West Coast of the United States show minute traces of radiation that can be traced to the Fukushima reactor disaster, according to an interdisciplinary team of scientists from Oregon State University and the National Oceanic and Atmospheric Administration.
The radiation levels in fish analyzed to date are far below anything that would pose a risk to humans who consume the fish, the research team emphasized. The findings are preliminary; additional fish remain to be tested.

"far below anything that would pose a risk to humans"
What about: "no treshold"?

“What we can say is that we have detected Cs-134 in fish thousands of miles from where that Cs-134 came from, and over a year since it was released,”…. “It's very interesting scientifically, and it can tell us more about tuna migration and what happens to radioactive releases, but it's nowhere near enough to be concerned about food safety.”
(papa here)
What is near enough? it is obvious the tuna industry is being impacted by earlier reports released in CA concerning the tuna fisheries and scientific evidence of radiation contamination – fishing is the lifeblood of the Oregon coast so it is interesting the scientists are admitting Cs-134 being found in any tuna, they have only tested a total of 70 pounds so out of the tens of 1000's of tuna being caught they were only able to test +/-7 fish and find Cs-134 which only has a life of say 4 years.
(again from the article)
The researchers first identified two Fukushima-linked isotopes – Cesium-137 (Cs-137) and Cesium-134 (Cs-134) – this July, in samples of fish caught and frozen in 2011. (did you catch that frozen fish from2011)
This particular combination of radioactive isotopes is produced by fission in nuclear reactors, and less commonly, nuclear weapons. Cs-134, in particular, is considered key to the Fukushima nuclear “fingerprint” because it decays very rapidly, with a half-life of just more than two years while Cs-137 persists for decades

It is a worry when they say "appropriate action may be taken before significant population effects have occurred." For a managed species, the only realistic intervention is to take it off the dinner plate.
I cannot envisage any sort of "appropriate action" which can magically restore a CHRONICALLY poisoned population of albacore tuna to health and vitality whilst swimming in the North Pacific nuclear sludge bucket.

found this pdf on the symposium though
As one of the effects of this earthquake and tsunami, large amounts of radioactive substances leaked into the North Pacific Ocean from the Fukushima Dai-ichi Nuclear Power Plant. The concentration of the radioactive substances, mainly 134Cs and 137Cs, in seawater decreased to a not detectable level within several months, even in the waters around the power plant. The radioactive contamination in the living resources of the waters off the Tohoku region has also declined to not detectable or quite low levels with time. However, in some areas, the concentrations in submarine sediments and some benthic organisms still remain at relatively high levels. We will continue to monitor the radioactive substances and examine their movement in the ocean ecosystems…..

SP: They lie and then in the next breath admit there are "high levels".
Do you think the Symposium attendees ate Fukushima sushi at the $130 Extravaganza Dinner on October 17 (page 7)? I bet not. Chilean bass maybe.
Liars in Japan. They would have fooled virtually everyone pre-Internet. But not now. The real history of the world is right here, right now. Not in Big Brother's publications. They live in the past of 500-year old communications.
They will not escape the verdict of 2012 historians. Their lies will collapse one day and I will be there to watch them fall. The Matrix Generation of intellectuals are far advanced compared to these feeble prevaricators.

night you wonderful lot!!
USA -Study will assess cancer risks -Flawed methodology? Media ignoring other studies?
the top industry trade group had argued against it, saying the study is “unlikely to produce scientifically defensible results.”
http://nuclear-news.net/2012/10/25/usa-study-will-assess-cancer-risks-flawed-methodology-media-ignoring-other-studies/
well the top trade group has pulled the monitoring and they will rely on maths to work out the dosages blah blah like the WHO report on the fukishima children.. same format to cover it up! and its so blatant!!
grrrrrrr!
peace

"In a briefing paper, the NRC staff says that given the known amounts of radiation released from nuclear reactors, researchers would not expect to observe any increased cancer risks for nearby residents."

"While Cs-137, which persists for decades in the environment, could come from other possible sources," is a tacit admission that Nnorth Pacific albacore already have trace pollution of Cs-137 from Chernobyl, nuke tests, etc.
No surprise that the combined activity of Cs-134 + Cs-137 are not expressed in Bq/kg of tuna meat. Key facts are being withheld by patronizing scientists.

"…appropriate action may be taken before significant population effects have occurred." I think they mean people. Can't you just see the government jumping up and down at how fast they must act?
We grew up near the Gulf Coast of Florida so we ate seafood most of our lives. It never occurred to us that the day would come when this was no longer possible. When the Macondo well blew and BP despoiled the GOM with corexit, I knew we could never eat seafood again and we have not. That was the end of it forever. However, many natives continue to eat GOM and other seafood such as tuna, so the they really needs to study this ASAP.
