Lightning Can Trigger Nuclear Reactions, Creating Rare Atomic Isotopes (sciencemag.org)

sciencehabit shares a report from Science Magazine: Rare forms of atoms, like carbon-13, carbon-14, and nitrogen-15, have long been used to figure out the ages of ancient artifacts and probe the nuances of prehistoric food chains. The source of these rare isotopes? Complicated cascades of subatomic reactions in the atmosphere triggered by high-energy cosmic rays from outer space. Now, a team of scientists is adding one more isotope initiator to its list: lightning. Strong bolts of lightning can unleash the same flurry of nuclear reactions as cosmic rays, the researchers report in Nature. But, they add, the isotopes created by these storms likely constitute a small portion of all such atoms -- so the new findings are unlikely to change the way other scientists use them for dating and geotracing.

      Heavy water is not a product of a nuclear reaction. It's produced by filtering ordinary, natural water and extracting the D2O. The water is used to slow down neutrons in a reactor. In a PWR (almost all nukes) it's kept at a high pressure and does not boil out of the system. At some point the heavy water is replaced. At this time it will only have a slightly elevated level of tritium (Half life, only 12 years).

There are circumstances where reactors have released (usually small amounts of) radioactive material into the air - these things are well-studied. Also, the potentially bigger environmental concern raised by some has been the affect of increased water temperature on fish and other aquatic life due to the release of cooling water into rivers and such.

      This "account of creation" begins to fall apart when comparing the internal inconsistencies:
      "And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his own image, in the image of God created he him; male and female created he them."
      But things get sticky with:
      "And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him. And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof."

      So which was it, Man first or Beasts first? And a further confusion arises as to just when Woman arrives on the scene. Was it after all that naming? "Sweet Cheeks", "Damn Fine Ass", and "Let's Make the Beast With Two Backs" must have given God second thoughts, and he created Woman to contain some of Adam's rampant dominioning over every creeping thing that creepeth. Though Adam still had a fondness for a damn fine Ass, even to this day.

      "There is still no disproof of the solid claims made in the Bible's record of creation."
      This is right, there is no disproof, because there are no solid claims, just a lot of hand waving, a "Fiat Lux!" or two, and taking Sunday off to catch a ballgame. The "Enlightened Creationism" posited above is still bullshit. Whether bullshit preceded the Creation of Adam is still not clear; I suspect so. But I'm entirely open to the explanation that Adam, out one day seeking Carnal Knowledge of a likely Ewe, stepped on a big steaming pile, and yelled up to the Heavens "What the hell is this crap?"

      Now about Radiocarbon Dating. This is very tiresome; 14C takes its damn sweet time decaying to form 14N. Counting Decays is so last century. Count the Atoms instead. The Mass difference between 14C and 14N is quite small, about 1:100K, but with a high enough Harmonic Order Cyclotron, they can be separated, and this has been done. Or with an Energy high enough for full Stripping in a Foil, 14C+6 comes out at M/Q=~2.333, and 14N+7 is M/Q=~2.000. Easy. But one historical problem with Radiocarbon Dating was getting a large enough sample to count, usually several milligrams is needed, and the counting for good statistics might take months.
      With these Accelerator Isotope Separation techniques, a microgram sample ionized in an ECRIS takes less than a second to analyze, and the sensitivity is enough for at least a hundred equivalent half-lifes; half a million years or so. Beyond that, the Noise level starts to rise, as secondary Transmutation processes come into play.

There's also a good historical record of 14C concentration in the atmosphere thanks to tree rings, glacial ice cores, and corals going back thousands of years. Example. Other than the mess made by 14C production since ~1945 thanks to atmospheric nuclear bomb testing, those concentrations jive with what would be expected primarily from the cosmic ray production. If lightning contributes too, it would have to be a relatively small proportion or the equilibrium achieved between 14C production and decay would be at a much higher concentration.

      It's also worth noting that the gamma-ray production from lightning, which is associated with the process producing 14C, is only observed for the most extreme lightning events, detected at rates of around 50 per day world-wide versus the millions of individual lightning strikes that presumably aren't strong enough.

      That was my thought too. Cosmic rays strike the atmosphere continuously and the resulting isotopes mix quickly to normalized background concentration ratios. IIRC, the assumed evenness of atmospheric isotopes is what allows all measurements, anywhere, to be treated as the same.
      Thunderstorms are "point" events on a planetary scale and usually include precipitation. The concentration of atmospheric rare isotopes is incredibly small (I looked up C-14, it's 1 or 1.5 atoms per 10^12 atoms of the carbon in the atmosphere). If lightning is locally producing higher concentrations of rare isotopes and they are immediately precipitated to ground level instead of diffusing, it seems that regions with regular storms could receive statistically more isotopes over time.

      You don't understand how science applies the principle of uniformitarianism. It's not an assumption. It's a testable hypothesis. Like if physics of the past worked the same as today, then we should see "X" in the evidence, otherwise we will see something different. Whether the experiment was conducted 5 minutes ago, 500 years ago, or 5 million years ago affects the practical aspects of doing the science, not the fundamental nature of how science is performed by making predictions and then going out and comparing the evidence to them.

      For example, we don't assume 14C decayed in the past like it does today. We can count annual growth rings in trees, corals, and glacial ice going back thousands of years to see whether the carbon isotope results match. Likewise, for longer-term isotopic systems like uranium-lead we can make predictions about how nuclear processes worked, and see if the geochemical signatures in natural nuclear reactors such as Oklo, which was active almost 2 billion years ago. There are also many tests of whether nuclear processes worked the same in the past via such things as astronomy, where the distances involved are large enough that you are looking back far into time. If nuclear processes worked differently in fundamental way, for example, then you'd see differences in the way that light fades after a star goes supernova as you looked at events further and further away. Scientists have always been interested in the possibility that fundamental physical constants have changed in the deep past, and have looked for evidence, but it's kind of a boring exercise because usually the results show no detectable change to within measurement limits.

      We don't simply assume this stuff works exactly the same and ignore ways to test it, especially when there is evidence for variation of rates of *some* processes today, and some fundamental things about the Earth have changed over the long term (e.g., little or no free oxygen in the atmosphere billions of years ago, or changes in the Moon's orbit that have affected the tides). Those differences yield different products. The more fundamental nuclear stuff, not so far.

      The only people who think scientists blindly apply the principle of uniformitarianism are usually pseudoscientists with an axe to grind or people who don't understand how scientists actually use it.

    Arguing that ISIL isn't an example of Islam, is a form of the No True Scotsman logical fallacy. While many Muslims reject ISIL as blasphemous, ISIL is run by Muslims. They are Muslim because they worship Allah as God and believe that the Qur'an as the literal word of God as given to the Prophet Mohammed.

    With respect to Christianity, the situation is similar. Many Christians consider violence committed for Christianity to be blasphemy. Yet the people who committed the violent acts, and those who do so today in the name of the Christian God, are still Christians because they worship Jesus Christ as God.

    You're essentially doing the same thing in regard to Christianity that you criticize the previous poster for doing with respect to Islam. The fact that some people use Christianity and Islam as excuses to engage in violent behavior does not mean that either religion is inherently violent or should be condemned.

    Your post is an example of why many Christians believe that there's a double standard applied to Christianity and Islam. It would be far more effective to say that of peaceful Christians don't want to be criticized for the acts of violent and hateful Christians, they shouldn't criticize peaceful Muslims for the acts of violent Muslims. The words of Jesus Christ apply here: Judge not, lest ye be judged.

    Each individual is responsible for their own behavior, peaceful or violent, good or bad. Let's be intelligent enough to understand that Christianity and Islam are defined by a few core beliefs shared by their followers, but encompass a wide range of beliefs outside of the core defining elements of those religions.

    Your post is also a troll. The grandparent post objects primarily to the original post being off-topic. If you read the post and comprehend it, you'll note that it is objecting to politics being inserted into discussions where it has no relevance. Slashdot posts plenty of stories where political discussion is on-topic. This isn't one of them.

      When I first read this incoherent little sample of your personal stream of consciousness, I assumed that it was a context-less braindump from some autistic super-genius, of the kind you sometimes get on Slashdot.

    There are 31,536,000 seconds in a calendar year (non-leap year).

    That puts the number of strikes about 2 orders of magnitude higher than you calculate.

    Snowflake status is politically and religiously agnostic. It only requires being unique like everyone else, melting when faced with real heat, and the ability to pile on top of other snowflakes to avalanche at the slightest peep. Conservatives, Liberals, Moderates, people off the artificially one dimensional political scale... Anyone can be a snowflake.

    That said, the idea of nuclear reactions being triggered by lightning does not seem any more shocking (pun intended) to me than a troll trying to turn a science post into an unrelated political discussion.
