Fukushima's Nuclear Signature Found In California Wine (technologyreview.com) 140

An anonymous reader quotes a report from MIT Technology Review: Is it possible to see the effects of the Fukushima nuclear disaster in California wines produced at the time? Today we get an answer, thanks to a study carried out by french pharmacologist Philippe Hubert and a couple of colleagues. "In January 2017, we came across a series of Californian wines (Cabernet Sauvignon) from vintage 2009 to 2012," say Hubert and company. This set of wines provides the perfect test. The Fukushima disaster occurred on March 11, 2011. Any wine made before that date should be free of the effects, while any dating from afterward could show them. The team began their study with the conventional measurement of cesium-137 levels in the unopened bottles. That showed levels to be indistinguishable from background noise.

But the team was able to carry out more-sensitive tests by opening the wine and reducing it to ash by evaporation. This involves heating the wine to 100 degrees Celsius for one hour and then increasing the temperature to 500 degrees Celsius for eight hours. In this way, a standard 750-milliliter bottle of wine produces around four grams of ashes. The ashes were then placed in a gamma ray detector to look for signs of cesium-137. Using this method, Hubert and his colleagues found measurable amounts of cesium-137 above background levels in the wine produced after 2011. "It seems there is an increase in activity in 2011 by a factor of two," conclude the team.

    You have proven we can detect previously unmeasurably small amounts of radiation. Seriouslly? You had to boil down an entire bottle of wine to 4 grams of solids, then put that into the core of a gamma ray detector, just so you can determine that instead of one atom of Cesium-137, there were two.

          No. The background noise statement was referring to unopened bottles. The "factor of two" statement refers to concentrated samples without water or glass shielding.

          It's still "a factor of two" compared to a baseline that is unstated and probably not much above background -- a meaningless statement couched in scientific terms.

          If you read TFA, however, it is a bit clearer:

        Add to that the sampling has no statistical significance at all. They have proven they can find a one bottle of wine with a tiny bit more than another.

        At least we can sit back and see how many weak minds soak this up.

      • If your unique DNA were found in what was smelled in Uluru it would be pretty conclusive the smell came from you in Kansas. Probably not possible in that case, but one needs to look at the statistics in the wine tests to confirm the analysis and the origin of the nuclide.
      • by AmiMoJo ( 196126 )

        Nope, nothing to do with any of that.

        Cesium detection is used to non-invasively date wines to prevent fraud. Vintage wine is worth more so of course people try to counterfeit it.

        Older wines show much higher levels due to the fallout from nuclear weapon testing.

        This is interesting because while it's obviously not non-invasive it does show that it is possible to use Cesium levels to date wine around the time of the accident.

        It's a good analogy, an atomic fart. It's the one the Japanese made with Nuclear Boi [youtube.com] and just like a silent but deadly fart it traveled across the pacific to find a home in American wine.

You have to check to make sure, but now that you have checked, the result appears less than overwhelming. Great. Move on, and know it isn't an issue. What we don't have to do is make it known in the popular press, only in agricultural circles would this be an important (but negative) result.

You are assuming this is about safety of wine, it isn't. And it is valuable to know if, for some reason, someone proposes to build 100 fukushima type plants (with all the poor choices that would entail).

    No...

    The team began their study with the conventional measurement of cesium-137 levels in the unopened bottles. That showed levels to be indistinguishable from background noise.

    What I conclude is that this testing method, removing the 99.5% water mass, simply makes it possible to detect otherwise undetectable amounts of cesium-137.

    Sounds more like a French "researcher" wants to scare people off California wine so they will buy more French wine. OMG! DOUBLE the radiation as before! And if that "double dose" of radioactivity is still 4 orders of magnitude less than, say, standing out in direct sunlight, then it's a bit dishonest to publish this "conclusion" and pretend it's very significant.

      Then you would be wrong. "Background" and "undetectable" are not synonyms. "Background" can be quite a bit higher than the detection limit.

      What removing the water and ashing the remainder does is concentrate the sample and bring the level above background, which is what you would expect if you concentrate anything. Doing the same thing to a pre-Fuk wine of recent vintage results in a reading of X. Post-Fuk you get 2*X. In both cases X is detectable and above background. Unconcentrated wines don't measure

    The only real use of this research beyond curiosity is authenticating wine (but only if there's enough that destroying a liter of it is worthwhile). Fukushima created a barely detectable bump compared to the few years before the incident.

    Looking at the graphs in the actual paper, The signature isn't really even visible compared to the spikes after the '50s nuclear tests.

    The levels of Cesium-137 are a radioisotopic measure, not a location measure.

          Thanks for pointing that out. My point is that the stuff coming out of coal are natural isotopes and whilst they should be collected the stuff coming out of the Nuclear are artificial products and generally much more toxic.

          If there is going to be issue about natural isotopes being released then they should not be released from Nuclear Industry processes either.

      About 94.6% of Cesium-137 decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137mBa, Ba-137m). The remainder directly populates the ground state of barium-137, which is stable. Ba-137m has a half-life of about 153 seconds, and is responsible for all of the emissions of gamma rays in samples of caesium-137. 85.1% of metastable barium then decays to ground state by emission of gamma rays having energy 0.6617 MeV.
