Trace Radiation Found In West Coast Tuna
CNN
May 28, 2012

[…] low levels of radioactive cesium from Japan’s Fukushima Daiichi nuclear accident turned up in fish caught off California in 2011, researchers reported Monday.

Tissue samples taken from 15 bluefin caught in August, five months after the meltdowns at Fukushima Daiichi, all contained reactor byproducts […]

But neither thought they were likely to find cesium at all, they said. And since the fish tested were born about a year before the disaster, “This year’s fish are going to be really interesting,” Madigan said.

“There were fish born around the time of the accident, and those are the ones showing up in California right now,” he said. “Those have been, for the most part, swimming around in those contaminated waters their whole lives.”

[…]

And if any fish are found with dangerous levels of radioactive material in their tissue, “It would be our responsibility to report it right away,” he said.

    Hmm. I have 4 cans of tuna in my cupboard that I bought 6 months ago. I am sure it is safer that what you can buy now. How long does it keep?

      BC sez…I have 4 cans of tuna in my cupboard that I bought 6 months ago.

      >I am sure it is safer that what you can buy now.

      SP: Not necessarily…depends on where the post-311 tuna traveled and the contamination level of their food.

      >How long does it keep?

      SP: A very long time…3 to 10 years…even longer for canned salmon. If we had been clairvoyant we could be rich now selling 2010 salmon and tuna fish. Probably still quite a stock of pre-311 cans in the heartland of America in mom and pop stores. The trick is reading the label codes. There's a radiation-free goldmine in those old general stores. Salmon especially since it is usually far more expensive.

      That four cans will have to keep you going for the next 3 BILLION years..

      It is great that they are testing for iodine and cesium, and the fast to decay poisons…

      Now how about testing for these 93?

    This story has a bit more detail than the San Diego story, enjoy those last few cans of tuna in your house. I won't buy anymore.

    ? …… … that was fast.

    So the Seals, Polar Bears, Eskimos, etc. Wheres that data?

  • tomarsandbeyond tomarsandbeyond

    From the article:
    "By comparison, naturally occurring potassium-40 levels average about 350 bq/kg"

    The amounts found "between 61 and 168 bq/kg." off of Japan and "about 10 becquerels per kilogram of dry weight" off California don't seem high enough to be harmful. Bring on the fish fry! They need to keep checking as levels might rise or be concentrated on some species.

    Radioactive Hook Up…

    This is what we have been saying all along; Japan's radioactive pollution is spreading Globally…

    Fisherman will now have to add Geiger counters to their tackle boxes!

    What a Nuclear Waste!

    …tuna samples off California had Fukushima radiation… back in AUGUST 2011…

    WTF!??

    What else are they delaying to report besides plutonium results?

  • Worth remembering:

    Nuclear Controversies by Vladimir Tchertkoff; Released in 2003, 51 minutes
    30:20 – According to Professor Yury Bandazhevsky (former director of the Medical Institute in Gomel), "Over 50 Bq/kg of body weight lead to irreversible lesions in vital organs" http://video.google.com/videoplay?docid=8746168177815160826#

    Worth keeping in mind:

    According to PEER’s news release in 2010, proposed new guidelines would permit the current lifetime limit of radiation exposure to occur in a single glass of water while significantly reducing EPA radiological clean-up standards, essentially permitting a 25 percent cancer per exposure (PEER, 2010 http://www.peer.org/news/news_id.php?row_id=1325).

  • Current derived intervention levels for radionuclides in food by FDA

    The specific Derived Intervention Levels are here: http://www.fda.gov/downloads/NewsEvents/PublicHealthFocus/UCM251056.pdf

    The specific “FDA derived intervention level or criterion for each radionuclide group” are as follows “for all components of the diet” for Strontium 90, Iodine 131 and Plutonium 238 and 239
    Sr-90 160 Bq/kg
    I-131 170 Bq/kg
    Cs-134 + 137 1200 Bq/kg
    Pu-238 + Pus 239 + Am 241 is 2 Bq/kg

    These guidelines state that the “alternate units for milk” in picocuries per liter are the following:
    SR-90 4400
    I-131 4700
    Cs-134 + Cs-137 33,000

    These are the levels tolerated in milk by the US FDA.

    • pure water

      What will be the intervention when such levels are achieved – mass funeral, or what? Sr goes to the bones 100%.It does not come out.Cs does, but 50 Bq of Cs stored in human body make irreversible tissue changes. Can you imagine how many atoms of Pu with these different half lives have to be present in order to provide 2 disintegrations every second? It is impossible, because if it is only Pu239 the amount will be completely different from the sample, which contains only Pu238.

    • jec jec

      One has to wonder tolerated for HOW LONG? It sounds like the FDA is looking at a single event situation, or is this for daily consumption over a lifetime. Lifetime is what we are talking here..Just Saying.

  • Finally, one more important comment about bio-accumulation.

    We are not just eating contaminated tuna, unfortunately.

    Why the ICRP and EPA Models for Radiation Risk Understate Risks Significantly

    EPA: Cancer Risk Coefficients for Environmental Exposure to Radionuclides
    http://www.epa.gov/radiation/docs/federal/402-r-99-001.pdf

    page 3

    "For both internal and external exposure, a risk coefficient for a given radionuclide is based on the assumption that this is the only radionuclide present in the environmental medium. That is, doses due to decay chain members produced in the environment prior to the intake of, or external exposure to, the radionuclides are not considered”

  • BreadAndButter BreadAndButter

    Maybe I missed it, but do we have any information how high those levels in the tuna are??
