Somewhere in Austria, winemakers are wondering how the American's can get away with putting radiation in their wine but they put anti-freeze in their bottles and everyone lost their minds.
Fukushima reactors lend exotic nuclear finish to California's wines
Savants reckon radiation released by the 2011 Fukushima nuclear kerfuffle has made its way into California's wine. A paper emitted this month by researchers at the University of Bordeaux Centre d'Études Nucléaires de Bordeaux-Gradignan (CNRS) in France revealed that levels of cesium-137 in the atmosphere rose as a result of …

Worse than anti-freeze!
There are detectable levels of Di-Hydrogen Monoxide (DHMO) in all California wines! DHMO is a well-known industrial solvent and coolant, and is used in virtually every commercial food growing operation in California! This chemical is adsorbed into all foods during production, and even after a thorough cleaning it is still present! Worse, it is present in all California produced foods, even if they are gluten free, dairy free, non-GMO, unfiltered and organically grown with no tree or ground nuts!
Ban all food produced in California! Write to your Congressman demanding the banning of DHMO, before it becomes so common you drown in it!

Because the levels of radiation are less than what you'd find in just about... anything around you. We're talking mBq per liter.
If you eat a single banana, you'd get more radiation exposure than if you chugged enough of this wine to give you alcohol poisoning.
Also, please, keep in mind that Radiation and Radioactive Particulate are different things. You can't really "put radiation" in anything, any more than you can "put light" in anything - most radiation we interact with *is* light, after all, and little of it lasts more than a few milliseconds.
Radioactive particulate is a different matter; it emits radiation.
Still, we are talking mBq/Liter. You might as well measure a beach by milli-granules-of-sand. Becquerels are not often used in professional communities regarding radiation because you wind up with measures on the orders of "Hundreds of Thousands of Becquerels" without it meaning * a dang thing *.
More common is the Curie.

> If you eat a single banana, you'd get more radiation exposure
It's true that the level of radiation being discussed in this story is tiny, and nothing to worry about.
That said, since we're discussing the banana equivalent dose, I'd point out that it's misleading. It rests upon the fact that bananas contain potassium, of which a very small percentage (in nature) is the radioactive isotope potassium-40.
However, your body doesn't retain potassium much beyond the amount it needs; anything in excess will be secreted via the usual channels. (#) Thus, unless you were deficient to begin with, eating a banana isn't going to noticeably increase the amount of potassium- and hence radioactive potassium-40- in your body, which will remain fairly constant. (Hence, in turn, the (incredibly low) level of radiation that it exposes you to should also remain constant.)
In short, the radioactive potassium from bananas doesn't "build up" inside your body if you eat more of them, in contrast to other radioactive substances that can accumulate in your bones et al.
(#) It doesn't really matter whether the potassium it got rid of is the existing or "new" stuff, as it has a half-life of just over a billion years.

Grapes do not absorb much
The interesting tests are cucumber peel and mushrooms.
My family has a couple of friends who pinched a Geiger counter post Chernobyl and measured everything they could get their hands on (which was going to end up on the table).
There were only two things which drove it off the scale. Cucumbers (specifically the peel) and forest mushrooms.

Just cucumbers? Not melons, squash or gourds?
Cucumber peel specifically. Cucumber collects all sh*t from where it grows and deposits it in the peel. This was in the days when lead fuel was still in wide use so a couple of years later I decided to run some spectrometer tests on the peel. The results were let's say not pretty. I have been peeling cucumbers ever since (the core has little or no contamination).

The peel also collects all (or nearly all) the useful nutrients. You know, the stuff that keeps you alive. The inside of the cucumber is mostly water. So, essentially, you have a choice.
* You can eat the whole thing, in which case you die slowly of radiation poisoning.
* Or you can peel it, in which case you die slowly of malnutrition.
(Unless, of course, the di-hydrogen monoxide gets you first.)

Re: Grapes do not absorb much
Interesting that rosé has less Cs than reds and supports your cucumber peel reading: rosé wines are either pressed or more often “bled” off, so the actual fermenting juice is separated from the grape skin, so it would seem that it’s concentrated in the skin, and not just on it or in the yeast used for the wine ( the white powder on a grape skin is actually yeast and can be used to ferment the grapes naturally, though it can be filtered out in “post processing”.
As for mushrooms, in Germany if you hunt boar, you have to do a radiation test on them as some of them are not clean for human consumption due to their personal consumption of forest mushrooms and sometimes have to be disposed of as low level radioactive waste, and there have been some studies about using fungi in radiation cleanup as they do clean some radioactive elements from the earth where they grow, following some studies in Chernobyl where fungi growing in the plant were much more radioactive than the supports they were growing on - and explains the glow in the dark wild piggies who love shrooms...

Re: Banana Equivalent Dose (BED)
A useful site conversion site.
https://www.translatorscafe.com/unit-converter/en/radiation-activity/
It gives 7.5mBq/litre as about 0.45 decays per minute, so if you drink the whole bottle (0.75 litre) you'll have to cross your legs for a long while to reach the 1860 particle decays in 1 BED minute (31 becquerel/gram)
and obligatory XKCD ref.

and if the article gave the exposure in µSv (or likely nSv), I wouldn't complain, what it did is give the following:

And Becquerel is about as intuitive as chains to the hogshead for fuel efficiency.

At a bottle per day, that's only eleven and a third years. Even if you give it up for Lent, you should be done by April 2032ish.
Hang on a minute...does this mean that we now can work out a formula to convert the BED in to a representative number of liver transplants, such that we could make a statement like "...a dose of radiation like that is equivalent to eating one banana, or to put it another way, a total of 6 months in rehab over a course of 4 visits, as well as 2 liver transplants"?

And, even more amusingly, at a blind tasting of sparkling white wines recently, a French judge scored an English wine more highly than Champagne.
Said English wine went on to claim the top prize.

They missed a source
It turns out the trees are very good at concentrating cesium and now that more of them are being burned near wine country, all that lovely cesium from the cold war that has been concentrated in trees is now being released into the air when those trees burn. The wines from down under seem to have less of an issue but it did show up with the major fires in the last decades. That mostly flat line on their graph is heading up towards the right if the scale is changed. One report from downunder was trying to understand why home fireplaces are releasing more of the stuff than forest fires. Last winter in Europe, most reporting stations are seeing a year on year increase in radiation in the air.

Re: They missed a source
I get the Asimov reference, but it was not R.Daneel Olivaw or R.Giskard Reventlov's plan. It was Levular Mandamus who set up the nuclear intensifier. The two robots merely did not stop the plan, in order to invigorate the human race.
This caused the demise of R.Giskard, as he did not have the flexibility to work around the first and zeroth law.
I always found it strange that R.Daneel was able to invent and invoke the zeroth law, and then partly ignore it to allow 'harm' the humans on Earth for their long-term benefit. He was quite an early humaniform robot (at least in the 'Spacer' era, and ignoring Tony and Georges Nine and Ten), so why was his positronic brain so adaptable?

Re: A dry red with notes of cherry and a pleasing strontium aftertaste...
I once bought some bottled water in Austria - from an alpine spring naturally. Or a Sunbeam Alpine that had sprung a leak...
Anyway, their food labelling regs are rather tougher than ours. One of the minerals it contained was strontium - and there was actually a small radiation symbol on the ingredients list. I didn't think to check if bananas carried a similar warning though.

After what I have read here, they bloody well should! (Perhaps the California ones do- they are not sold here)
Now, I have to wait until dark, then flip off the light-switch to see which ones glow!
They will go to my well-stocked Hazardous Waste bin, along with all those toxic CFLs, that keep breaking here (cough-cough!) and I shall only eat the safe bananas at breakfast!

Millibequerels per liter?
Seriously?
Are we worrying about this?
You literally can't detect levels this small except when measuring by hundreds of gallons *because natural background overpowers it so drastically*. Even on such a scale, you have to evaluate *chemically* unless you have *extremely sensitive equipment*.
We are talking 15mbq per liter. 0.015bq per liter. For reference, take a banana, average, 7". Take a 0.1778mm slice of that banana. Literally so thin you can see through it.
Then blend it up in a 1 liter bottle of water.
THAT IS THE LEVEL OF RADIOACTIVE EXPOSURE WE ARE TALKING ABOUT.

Friday 20th July 2018 09:19 GMT I ain't Spartacus
The article actually tells you why they're doing it. They've built up a database of the relative levels in wines over the years - and that allows them to test any vintage bottle and make an estimate as to whether the label has been faked - and the wine is actually something from a cheaper year.
Remember there's serious money involved in this. My Dad bought a case of 96 Chateau Lafite for about £2k as part of his pension investment in 99. He decided to take a couple of riskier punts with small amounts. Sold it for over £8k ten years later. There's quite a lot of incentive to commit fraud when single bottles of vintages are going for £1,000 or more.

At this point I'm debating whether to sign up for radioactivity testing of French red wine. Especially if it means being sent hundreds to bottles for free.
If I survived[1] I'd certify that they were free of radioactivity..

Re: 1952?
That's because the plutonium 239 turns into uranium 235
Uh? I'm puzzled as to the process that makes Pu-239 into U-235... Fission of U-235 produces a zoo of isotopes, nearly all of them radioactive. The proportions of each isotope follow something called the M-curve in terms of atomic mass with most of them being roughly half of 235. The commonly-produced longer-lived ones like Cesium-137 (half-life about 30 years) are the ones to worry about since the short-lived ones are gone in a few milliseconds, days or weeks, for example Iodine-131, half-life 8.5 days.
The same thing applies to the fission of Pu-239 nuclei, most products are roughly half of 239 which is damn close but not exactly the same as the fission of U-235. It's one way to characterise a nuclear test, to determine whether it was a uranium or plutonium core (there are other ways and there are methods to obscure the results if the tester doesn't want others to find out easily).
TL;DR -- the Gadget exploded at Trinity in July 1945 released Cs-137 into the atmosphere just like Little Boy did over Hiroshima in early August a month later. Saying that, some Cs-137 probably escaped into the wild from the startup of the Chicago Pile-1 reactor back in December 1942.

Re: 1952?
Pu-239 has a longish half-life, about 24,000 years. Any Pu-239 created in the early days of atomic weapons development in the mid-40s will not have experienced much radioactive decay -- one online calculator I've used suggests that about 0.2% of that original Pu-239 would have decayed into U-235.

Re: 1952?
However - there was practically no Caesium-137 in the atmosphere before we started trying to make nuclear weapons.
However I would bet the first release was when some poor bugger was tapping a hemisphere with a ruler and got a blue light and died few days later after finishing his homework.

A superb 2017 Cali Cabernet Sauvignon..
This really is a superb 2017 Cali Cabernet Sauvignon, with its aromas of rich dark currants, nectarine skins, gushing blackberry, but lots of fragrant tobacco, rich soil, white flowers, smashed minerals and metal. Medium-bodied and saucy but racy acidity stabilises the wine nicely – it’s definitely from the north facing vineyard; a piquant of 137 and it glows in the dark…

Friday 20th July 2018 11:06 GMT Credo
So,... a report generated by a French organisation, the largest winemakers in the world, is trumpeting an increase in Cs137 which "theoretically, may "potentially" make Californian wine dangerous to drink.
I can't see any potential for self interest here,... none at all,... not even slightly.

They salvage steel from old battle ships, because they contain large amount of steel made before the nuclear age, so it doesn't contain radioactive isotopes like modern steel, and thus doesn't interfere with modern medical and scientific equipment.

Re: Same reason they use steel from old battleships for medical scanner.
Kinda, sorta, ish.
They did make "isolation rooms" out of scrap pieces of steel armor plate salvaged from warships, yes. This was to minimize background radiation when measuring exposure of various folks for various reasons. But that was then, this is now. Today, they just use normal metals & correct for instrumentation error. Computers are kinda handy when it comes to that kind of thing.
One other bit of marine salvage that I am aware of ... SLAC, Sandia and Lawrence Livermore all have lead shielding that was salvaged from centuries old ship's ballast. Most of the stories included pirates of the Caribbean; some included lurid tales of how the ship was sunk. Allegedly this was because of the old lead's lack of man-made radiation, which would skew the data. Again, modern computers make this kind of thing pointless ... One of my older mentors wrecked the romantic stories by telling us that the real reason they used it was because it was the cheapest lead they could get their hands on at the time.
