How Atomic Particles Helped Solve A Wine Fraud Mystery

Caesium 55 Cs , or radiocaesium , is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from natural fission of uranium It is among the most problematic of the short-to-medium-lifetime fission products because it easily moves and spreads in nature due to the high water solubility of caesium’s most common chemical compounds , which are salts. Caesium has a half-life of about The remainder directly populates the ground state of barium, which is stable. One gram of caesium has an activity of 3. Caesium has a number of practical uses. In small amounts, it is used to calibrate radiation-detection equipment. Caesium is not widely used for industrial radiography because it is hard to obtain a very high specific activity material with a well defined and small shape as cesium from used nuclear fuel contains stable cesium and also long lived Cs

Trace amounts of isotope from Fukushima disaster found in California wine

Large quantities of artificial radionuclides from the fission of uranium were released into the atmosphere during the atmospheric nuclear tests of the s and s. Today, there remain only radioelements having a long radioactive period such as caesium Cs with a half-life of 30 years. Since the nuclear tests, this caesium was deposited over time more or less evenly throughout the globe and in particularly on the vines.

It is normal to find traces of Cs on the grapes and therefore in the wine.

The Cesium Test. Jim Elroy had a hunch that the wine in the Jefferson bottles did not date back to the 18th century, but he needed a way to.

Those tests released vast quantities of radioactive material into the air and triggered fears that the nuclear reactions could ignite deuterium in the oceans, thereby destroying the planet in a catastrophic accidental fireball. Atmospheric tests ended in , when China finished its program, but the process has left a long-lasting nuclear signature on the planet.

One of the most obvious signatures is cesium, a radioactive by-product of the fission of uranium After release into the atmosphere, cesium was swept around the world and found its way into the food supply in trace quantities. Such an addition is rarely welcomed. But in , the French pharmacologist Philippe Hubert discovered that he could use this signature to date wines without opening the bottles.

Radioactive Traces of Fukushima Have Been Found in Wine All The Way in California

Following the Fukushima nuclear power plant accident , radioactive waste leaked into surrounding areas and contaminated waters and food. Seven years later, traces of the disaster were found half a world away — in California’s wine. Cabernet sauvignon, for example, had double the amount. The researchers used two methods to look for traces of a radioactive isotope called cesium The first method was developed about 20 years ago and could detect the particles through the wine bottle, without destroying or opening it.

Since the presence of cesium prior to is impossible it’s a man-made isotope first released into the surroundings by nuclear testing in the midth century , it has proven quite effective for detecting fraud in old vintage wines, according to the study.

Philippe Hubert and his team used the same principle as carbon dating to calculate the age of wine by measuring its caesium levels – the.

Physicists at Bordeaux University have developed a method of dating wine by measuring its radioactivity. Philippe Hubert and his team used the same principle as carbon dating to calculate the age of wine by measuring its caesium levels — the amount of radioactive material it contains. Wines from Bordeaux, Burgundy, Alsace and Corsica dating from can be differentiated according to caesium levels.

The research is funded by the French fraud office. Their laboratory was installed to check vintages after recent fraud cases although where higher sensitivity is required, the experiments are performed in a high-security underground laboratory on the French-Italian Alpine border. Previous experiments have been able to date wine approximately using carbon decay, but required the wine to be opened, evaporated and burned, using the ashes for measurements. Hubert and his team produced initial measurements in this way, but the new technique means the vintage can be checked without opening the bottle.

How Radioactive Dating Is Used to Authenticate Wine

The infamous Hardy Rodenstock Jefferson bottles. Photo: New District website. Wine fraud is a phenomenon with an enduring fascination. In May this year, German wine collector Hardy Rodenstock, long suspected of wine fraud, died and with him went the secret of the supposed hidden Parisian wine cellar in which he claimed to have discovered bottles of wine from the late s that had been owned by Thomas Jefferson.

Carbon 14 dating is the method archaeologists use to establish the age of organic materials, such as plants and animals, and plays a key role in our knowledge of the dates of prehistory — the end of the last Ice Age, the demise of dinosaurs, the eruptions of volcanoes, etc. More recently, Cesium from nuclear fallout is being used to date wine and has helped detect wine fraud.

Did the Fukushima incident in leave its signature via the Cs radioactivity in wines, mainly from the Nappa Valley? This is a short note about a few.

In , French pharmacologist Philippe Hubert discovered a new way to date wine. In the s, countries like the U. This material has left a significant amount of nuclear waste across the world, most notably Cesium, which has found its way into foods. Hubert realized that traces of Cesium could date wine accurately without opening it, thus preventing wine fraud. Detecting wine with no Cesium would necessarily mean that was made after , the year of the last nuclear test. However, the Fukushima nuclear power plant meltdown released a new wave of radioactive residue into the atmosphere.

Hubert and his colleagues conducted a special test to detect whether the disaster had any effect on Californian wine made between and The test involved opening and evaporating the wine and converting it into ash. Afterwards, the ash was scanned for Cesium, and Hubert discovered a noticeably different amount of the chemical in wines dated before and after the Fukushima disaster. Nevertheless, this difference was only apparent after opening and ruining the wine, so it has no practical use for wine dating.

Wines dated more recently will still appear to have no traces of Cesium, as they should. How are we different? Why a Machine Learning Investment? Using Miniature Robots to Fix Engines.

Some wealthy wine aficionados are comfortable spending millions on supposedly rare vintages. Here are some cases to illustrate the problem and ways to investigate the fraud. The world of rare and expensive wine collecting is populated with high rollers who enjoy the one-upmanship that private sales or public auction purchases often bring. They enjoy the limelight of owning one or several bottles of an extremely rare vintage that renowned wine experts have authenticated.

A fine winery produces a limited number of cases of a particular excellent vintage and connoisseurs desperately want it. That vintage is ripe so to speak for counterfeit versions.

As long as rich men are willing to pay exorbitant amounts for old, fermented juice, there will be schemers willing to dupe them out of their money. But if you’re dropping a cool half million on four bottles of wine supposedly owned by Thomas Jefferson true story , you want to make sure you have the real thing, right? You can, thanks in part to the atomic bomb.

The art of wine forgery isn’t really about creating an authentic-tasting wine; the bottle is equally important. Collectors rarely crack open a bottle upon sale, and old wines can vary widely bottle to bottle after all those years. Plus, when it comes to wine, human brains are easily fooled by expectations.

Inspired by similar tests conducted in the aftermath of the Chernobyl disaster , the French team decided to analyze the California wines for traces of radioactive particles, specifically cesium, a man-made isotope. Their findings, newly published in the pre-print online journal Arxiv , suggest that currents and atmospheric patterns carried radioactive particles across the Pacific, where they settled on grapevines growing in California’s wine regions.

The team writes that bottles produced following the nuclear meltdown contain increased levels of cesium, with the cabernet revealing double the amount of pre-Fukushima radiation. This method, which allows researchers to conduct tests on unopened bottles, is a key tool in detecting wine fraud, or the mislabeling of newer wines in order to inflate their prices. After failing to detect cesium in the unopened bottles, the physicists vaporized the wine. To study co-author Pravikoff, the study is more about scientific curiosity than a tangible threat to public safety.

Dating the wine is a simple process of matching the amount of cesium to atmospheric records from the time the wine was made.

July 24, report. Michael Pravikoff and Philippe Hubert have written a paper describing their study and have posted it on the arXiv preprint server. Prior research has shown that after nuclear accidents such as the Chernobyl disaster in , isotopes such as cesium a radioactive byproduct produced by fission of uranium can be absorbed by plants.

Where they wind up is generally dependent on geography and the direction of the wind. Grape vines are one such plant that can be impacted by the isotope—it can show up in wine produced from the grapes. In , one of the researchers in this new effort discovered that he could date bottles of unopened wine by testing them for cesium levels. Such levels are not considered dangerous for humans, however, because they are too low.

In this new effort, Hubert and his colleague Michael Pravikoff wondered if the same situation might now be the case for wines made in California after the Fukushima disaster—prior research by other teams had shown that some degree of fallout had made its way across the Pacific Ocean. To find out, the pair used the same technique used to test bottles of wine produced after Chernobyl—namely, using sensors to measure gamma rays in proportion to the isotope levels emitted from unopened bottles.

The researchers report that this approach failed—likely because the levels of the isotope were too low. Undeterred, they opened some of the bottles and tested them more closely. This resulted in reducing the wine to ash. The research pair then tested the ashes with a gamma ray detector and found trace amounts of cesium The researchers reiterate that the levels they found pose no threat to human health—officials with California’s health department have also issued statements promising that the isotopes found in California wines or other agricultural products pose no threat to human health.
