The strange case of solar flares and radioactive elements
August 23, 2010 BY DAN STOBER(PhysOrg.com) -- When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics.
It's a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles away.
Is this possible?
Researchers from Stanford and Purdue University believe it is. But their explanation of how it happens opens the door to yet another mystery.
There is even an outside chance that this unexpected effect is brought about by a previously unknown particle emitted by the sun. "That would be truly remarkable," said Peter Sturrock, Stanford professor emeritus of applied physics and an expert on the inner workings of the sun.
The story begins, in a sense, in classrooms around the world, where students are taught that the rate of decay of a specific radioactive material is a constant. This concept is relied upon, for example, when anthropologists use carbon-14 to date ancient artifacts and when doctors determine the proper dose of radioactivity to treat a cancer patient.
Random numbers
But that assumption was challenged in an unexpected way by a group of researchers from Purdue University who at the time were more interested in random numbers than nuclear decay. (Scientists use long strings of random numbers for a variety of calculations, but they are difficult to produce, since the process used to produce the numbers has an influence on the outcome.)
Ephraim Fischbach, a physics professor at Purdue, was looking into the rate of radioactive decay of several isotopes as a possible source of random numbers generated without any human input. (A lump of radioactive cesium-137, for example, may decay at a steady rate overall, but individual atoms within the lump will decay in an unpredictable, random pattern. Thus the timing of the random ticks of a Geiger counter placed near the cesium might be used to generate random numbers.)
As the researchers pored through published data on specific isotopes, they found disagreement in the measured decay rates - odd for supposed physical constants.
Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation. The decay rate was ever so slightly faster in winter than in summer.
Was this fluctuation real, or was it merely a glitch in the equipment used to measure the decay, induced by the change of seasons, with the accompanying changes in temperature and humidity?
"Everyone thought it must be due to experimental mistakes, because we're all brought up to believe that decay rates are constant," Sturrock said.
The sun speaks
On Dec 13, 2006, the sun itself provided a crucial clue, when a solar flare sent a stream of particles and radiation toward Earth. Purdue nuclear engineer Jere Jenkins, while measuring the decay rate of manganese-54, a short-lived isotope used in medical diagnostics, noticed that the rate dropped slightly during the flare, a decrease that started about a day and a half before the flare.
If this apparent relationship between flares and decay rates proves true, it could lead to a method of predicting solar flares prior to their occurrence, which could help prevent damage to satellites and electric grids, as well as save the lives of astronauts in space.
The decay-rate aberrations that Jenkins noticed occurred during the middle of the night in Indiana - meaning that something produced by the sun had traveled all the way through the Earth to reach Jenkins' detectors. What could the flare send forth that could have such an effect?
Jenkins and Fischbach guessed that the culprits in this bit of decay-rate mischief were probably solar neutrinos, the almost weightless particles famous for flying at the speed of light through the physical world - humans, rocks, oceans or planets - with virtually no interaction with anything.
Then, in a series of papers published in Astroparticle Physics, Nuclear Instruments and Methods in Physics Research and Space Science Reviews, Jenkins, Fischbach and their colleagues showed that the observed variations in decay rates were highly unlikely to have come from environmental influences on the detection systems.
Reason for suspicion
Their findings strengthened the argument that the strange swings in decay rates were caused by neutrinos from the sun. The swings seemed to be in synch with the Earth's elliptical orbit, with the decay rates oscillating as the Earth came closer to the sun (where it would be exposed to more neutrinos) and then moving away.
So there was good reason to suspect the sun, but could it be proved?
Enter Peter Sturrock, Stanford professor emeritus of applied physics and an expert on the inner workings of the sun. While on a visit to the National Solar Observatory in Arizona, Sturrock was handed copies of the scientific journal articles written by the Purdue researchers.
Sturrock knew from long experience that the intensity of the barrage of neutrinos the sun continuously sends racing toward Earth varies on a regular basis as the sun itself revolves and shows a different face, like a slower version of the revolving light on a police car. His advice to Purdue: Look for evidence that the changes in radioactive decay on Earth vary with the rotation of the sun. "That's what I suggested. And that's what we have done."
A surprise
Going back to take another look at the decay data from the Brookhaven lab, the researchers found a recurring pattern of 33 days. It was a bit of a surprise, given that most solar observations show a pattern of about 28 days - the rotation rate of the surface of the sun.
The explanation? The core of the sun - where nuclear reactions produce neutrinos - apparently spins more slowly than the surface we see. "It may seem counter-intuitive, but it looks as if the core rotates more slowly than the rest of the sun," Sturrock said.
All of the evidence points toward a conclusion that the sun is "communicating" with radioactive isotopes on Earth, said Fischbach.
But there's one rather large question left unanswered. No one knows how neutrinos could interact with radioactive materials to change their rate of decay.
"It doesn't make sense according to conventional ideas," Fischbach said. Jenkins whimsically added, "What we're suggesting is that something that doesn't really interact with anything is changing something that can't be changed."
"It's an effect that no one yet understands," agreed Sturrock. "Theorists are starting to say, 'What's going on?' But that's what the evidence points to. It's a challenge for the physicists and a challenge for the solar people too."
If the mystery particle is not a neutrino, "It would have to be something we don't know about, an unknown particle that is also emitted by the sun and has this effect, and that would be even more remarkable," Sturrock said.

The becquerel (Bq) unit equates to one decay per second. For comparison, natural potassium (40K) in a typical human body produces 4,000 disintegrations per second (i.e. 4 kBq of activity). The nuclear explosion in Hiroshima (14 kt or 59 TJ) is estimated to have produced 8x10 E24 Bq.

The core's rotation speed is best indicated by the subtle ripples driven by gravity, i.e. so/called the the g-mode waves, which get distorted as they pass through the Sun. They're believed to occur when gas churning below the surface plunges even deeper and collides with denser material, sending ripples propagating through the interior and up to the surface, the equivalent of dropping a stone in a pond, but in space.

My sincere congratulations to the involved, who noticed the variations, made the initial assumptions (that the effect might be sun-related), and then took the effort to sift through data to find some evidence. Science as it should be! :)
Even if nothing more comes out of this in the near future, be it for whatever reason (like not being able to come up with a sufficiently satisfying theoty, for example) - if confirmed, they have just found a way to measure the rotation period of the Sun's core! I mean, even that alone is a great achievement - the more so for being just "accidental" (as many of the greatest finds in physics actually were..)

I am not sure I understand what you are referring to but neutrinos are neutral radiation, they are their own antiparticle. The rate of decay would either speed up of slow down depending directly on the intensity of the background of neutral neutrino radiation.

At the moment I can think of 3 possible candidates for the observed variations in decay times:
A.) Solar neutrino flux. The closer we are or the higher the activity, the higher the flux. This is a very promising candidate indeed. Just the mechanism needs to be figured out. Maybe some of the neutrinos DO indeed react - particulary with the atomic nuclei? Adding/substracting energy, essentially altering the decay times? We will see..
B.) Magnetic flux variation. Earth indeed resides "inside" the Sun's magnetic field, which is directly related to the Sun's core. The strength of this field varies with distance AND position of Earth in relation to the core,aswell as with it's rotation, as the magnetic field is not uniform and also strongly depends on the surface activity.

Hey: you only mentioned 2 of those 3 candidates - what's your third idea?
Well, we already know neutrinos interact very weakly with nucleii, or else our detectors would'n't work! So this is a top contender imo. Absolutely *fascinating* that an interaction/collison would *increase* stability though...
I seem to recall that intense magnetic fields have been tested on radioactivity with a null result. If they hadn't, we'd be able to unify the electroweak with the electromagnetic force right?

That's true with photons and gravitons sure, but there are interactions (such as quantum teleportation) where information (albeit non-useful information) is conveyed without exchanging energy.
And if we're seeing new physics and a new particle here, then all bets are off until we model it accurately. I'm just saying that if it's a new particle from the Sun, it probably couldn't carry energy or we would've noticed it by now in accelerator collisions.

..The surface activity dependance would also represent the corelation with the flares - causing directional fluctuations in the field. Albeit, for now, I can hardly come up with any possible explanation as to the underlying mechanism responsible for the observed decay variations in regard to Earths position in the Solar magnetic field, it might be a candidate, as it seamingly could be in unison with the observed data.
C.) Position in the gravity well. Or "how deep" the observed element (located on Earth) is at the time of observation. As our planet orbits on an eliptical orbit, it is closer to the Sun at certain times of the year - or with other words "deeper" within Sun's gravity well. Albeit the decay times are most certainly related to this aswell, it is a very unlikely explanation, as this effect is purely observer dependat - eg. the observer would have to be "outside" of the particular gravity well, to measure a change caused by this effect. Relativity at its best :)

I'll try to explain.. Take for example an orbiting planet. The planet is orbiting the host star at a speed a little bit less than the escape velocity - eg. its orbit is slowly decreasing with time, because the planet doesn't have enough kinetic energy (relative to the star).
Now imagine an object of non-negligible mass/kinetic energy snapping into the planet - altering the relative momentum of the planet towards the star in a way, that makes the planet orbit a bit faster, but still not above escape velocity.
This way it will take longer till the planet smashes into its host star - increasing stability of the whole system, so to speak.. :)

The same side of the Moon always faces the Earth, not the Sun. The Moon goes through equal day and night cycles too, just much more slowly than the Earth.
And this effect doesn't depend on day and night anyway, as far as we've seen so far - it depends on solar proximity, solar flares, and the neutrino 'hot spot' of the rotating solar core.

Yes, of course I know one side of the moon always faces the Earth and it goes through day/night cycles, but because of the Earth and the fact that only one side faces the Earth at all times, the light side would actually have less neutrino interaction (if any such interaction occurs) than the dark side, because when the Earth is between the sun and moon, the Earth would block more neutrinos over time, from hitting the light side.

Okay we have problems here - relativity is so far consistant. Now the issue hear is that they are suggesting that by measuring radioactive decay on earth you will know 8 minutes in advance that a huge solar flare is coming at earth. This violates the rules that information cannot travel faster than the speed of light.
issue two Everything in this solar system is probably a by product of our sun on some level except trapped comets. SO are we suggesting that most of the radioactive material on Earth is already coupled with material in the sun. Like quantum level coupling spins and all that.
three - back to the article - it states that possibly nuetrinos are doing this or some other particle that is being ejected from the sun --- but since nothing travels faster than light we would already know about the solar flare by the time the nuetrinos got here.
Aren't Nuetrinos notorious for not reacting with anything - like huge vats of water.

First of, our current quantization of time is by definition directly related to isotope decay rates. So, if the effect described by this article really is causing decay rates to "slow down" (or speed up), the question would be: Did "time", as we know it, just got slowed/sped up? :-D
After comming up with this, I realised, that the explanation of what's really happening there, might not be as simple. After all, a decrease of speed of the decay process might not be the only viable explanation to the observed decrease in the average rate of isotope decay.
It is possible that the increased neutrino flux is somehow just temporarily "prohibiting" the decay process to happen - like for example from a side effect caused by oversaturation of the nucleus, or other possibilities like the ones I meantioned in previous posts, where energy transfer between the neutrinos and the nucleus was considered.
Howgh :)

"The decay rate was ever so slightly faster in winter than in summer."
Notice the rate dropped slightly during the flare and the decrease started about day and a half before the flare. This would indicate something is going in the interior of the sun before the flare surfaces. From this we could predict a solar flare was coming soon.
Also notice the decay rate was ever so slightly faster in the winter, when the earth is at its closest to the sun. This indicates that as the solar neutrino radiation increases, probably by the inverse square rule, as the earth get closer to the sun. It does not indicate that an increase in neutino radiation inhibites radioactive decay, just the opposite.

If you place the Earth into more dense vacuum (no matter, which weakly interacting particles its density is really formed by), the speed of energy spreading and therefore the time will slow down and gravity constant will decrease, because inside of such dense environment the material object will "swell" while losing its weight. It will affect the fine structure constant, for example.

Of course, this is why I asked Skeptic_Heretic and david_42, how did they come into their speculations. The more particles is in vacuum, the easier the massive objects are "dissolved" with it. For example, if we place particles of common matter into dense vacuum around black hole, they will evaporate into accretion radiation there. It may be not so easy for us to distinguish vacuum density variations from changes of physical constants. By recent French study the light speed slows down by a few centimeters per second each year as determined by Lunar ranging data.

Albeit there are better and more stable/accurate methods to measure time, like for example magneto-optical traps (which utilize lasers, as you wrote above), the definition of a standard "second" in the International System of Units is still based on "periods of radiation" of the caesium-133 atom, which is closely related with its half-life/decay rate.
Why so complicated, when you can just say "into more curved space" or "deeper into a gravity well" - and then it is just a basic effect of relativity, rather than making up piles of nonsensical terms to describe it.. (?)

Because there is no direct apparent logic between curvature of space and stability of particles.
For example, most of physicists believe, the accretion radiation occurs only when the particles falling into black hole are colliding mutually under friction. They do not realize, accretion radiation is produced even when single particle is falling into black hole.
Whereas in context of dense aether theory the curved space-time, which manifests with gravitational lensing is really area of more dense vacuum foam, something like blob of jelly around massive bodies. It has its own mass (dark matter) and surface tension (dark energy).

This doesn't affect the rest of insights of yours about shifted time definition in presence of weakly interacting particles, which is actually quite correct and relevant. You just fabricated the evidence for it with using of radioactive decay based definition of time too easily. Because our current definition of time is NOT based on radioactive decay, its "quantization" the less. Period.

If the observer goes into the "denser aether" region together with the observed sample, he will not measure any change. But if you take 2 samples and send one sample into a region with "denser aether" while keeping the second sample outside, with the observer holding position, and then return the sent sample, the observer should be able to measure a change in the returned samples decay progression - by comparing (relating) the both samples.
And now a classic: Because arguments do not allways have to be based on some (wiki) links, as you might believe..

But it's a certain way of thinking, which makes even the relativity relative, so it cannot be replaced with it. Dense aether theory is actually even more relativistic, then the relativity alone - because its postulated so. Aether is invisible recursive geometry based concept in it - it cannot be never seen directly.
For example, from relativity follows, universe should expand in increasing rate, which introduces an inertial reference frame for Universe. In dense aether theory it's a dispersion effect - we would perceive ourself at the center of Universe expansion at all places of it - which violates Big Bang concept.

All I did point out is, that those two "things" are closely related - which you would probably agree with, if you understood the subject in full extent.

I just pointed out a relation, and used it as a base for a few simple assumptions.

On to seasonality, we're assuming neutrino "density" increases closer to the sun. OK, I'll buy it. The guess is that this increase in neutrinos slows the decay. I like SH's hypothesis about density. Since the solar flare activity isn't tied to neutrino activity, yet, no contradiction.

Whereas the graphs in later article are clearly indicating, that during solar flares the decay speed actually decreases in contrary to first Jenkins article.
It context of dense aether theory such finding has a good meaning, as it predicts, massive objects should be surrounded with dark matter composed of antineutrinos, which are accelerating beta decay, whereas solar flares are composed of neutrinos, which are decelerating it, as I explained above. At least we have some phenomena, in which this theory can be tested.

The trouble is that solar flares are relatively brief - it's an effect that lasts 20 - 40 minutes. The studies of annual variations were performed over a period of two years and still the statistical errors are just a little below the expected effect. If solar flares caused an effect observable over few minutes, it would surely have to be much larger to stand out from the noise.

It fairly easy to understand why they used the term Transition of cesium. The odd part was they didn't say what kind of transition till the end.
The hyperfine transition has to do with the spin of the electron. The magnetic moment of the spin can be either the same as for the nucleus or the opposite of the nucleus which has a higher energy level than for the same spin. This a much lower energy transition than for a change of orbitals. Thus the change can have a higher frequency.
Apparently this spin flip frequency is more stable than most other oscillators. Hydrogen masers are more accurate but it is more difficult to maintain their stability.

This article does not state that the neutrino radiation slows down the rate of radioactive decay. It states that the rate of decay slows down slightly a day and a half before a solar flare becomes visibile. Why? Probably because less neutrino radiation is being created below where the flare will erupt.
This article also states that radioactive decay increases slight in the winter. The earth is closest to the sun during this period. One can assume the neutrino radiation from the sun would follow the inverse square and be slightly more intense closer to the sun.

Thanks. I had it backwards twice, but that's roughly what I thought. I thought the solar flare would increase neutrino output and the output was prohibitive, not causative. So, is it possible now that this discovery could suggest that the sun is completely responsible for decay? I think someone else alluded to the possibility of little to no decay in intergalactic space.
Also, what was wrong with Zaero's last two responses? Is he, Alize, Jigga, etc making stuff up again? Are his percentages at least correct? How does the strong force affect decay? Sorry for my ignorance.

Let's assume that neutrino radiation is responsible for almost all radioactive decay. From the slight changes caused by the sun it is safe to say that almost all the radioactive decay is caused by the natural background of neutrino radiation whose source is from elsewhere in the universe. So interstellar space radioactive decay rates would be only slightly less than they are in our solar system.

A scalar field is simply a tensor field of order zero, meaning it is independent of coordinate systems and displays characteristic distribution homogenously allowing two disparate observers to agree upon a measurement.

“Peter Cooper of the Fermi National Accelerator Laboratory in Batavia, Ill., recently did just that. He obtained and analyzed data from the Cassini mission to Saturn. Deep-space probes usually generate power from the heat emitted by a chunk of radioactive material—plutonium-238 for the Cassini spacecraft. Cassini journeyed as close to the sun as Venus and then far back to Saturn, spanning a much wider range of distances from the sun than Earth does during its yearly orbit. If the sun had an effect on plutonium decay, the fluctuations would have been much more substantial than those seen in Earth-bound experiments. As a result, Cooper reasoned, Cassini should have measured substantial changes in its generator’s output. It didn’t. (His paper is posted online at http://arxiv.org/...)"

My only hunch is that if something is really going on that there is some quantum entanglement involving the quantum fields of these forces that is somehow set up. I am not going to put any bet on this, for even still this is an extreme dark horse prospect. Neutrinos produced in the core of the sun interact so weakly with anything sitting on a lab bench, whether that being a neutrino detector or an isotope of some element, that it is difficult to imagine there being some causal process going on here."

Definitely agree. Having read some of Dr Fischbachs papers on the "fifth force" that were reported on here a few years ago, there was a tendency to stray from simple explanations in order to explore new possibilities (that really didn't seem warranted in light of the evidence he presented). From what I can see, this trend has continued back to his original work in the *mid 80s*. This is one reason I'd want to see independent verification of his results before investing more time in his theories. Papers (and popular news accounts) are listed in the link I gave above. If you're not familiar with Dr. Fischbachs work, check some of them out before giving this current claim further thought.

Disagree. If current observations are correct, the Universe is flat. The relevance to this is that if the Universe is flat, and our formulae are reasonably close to correct then the Universe has a net zero energy, meaning that something did come from nothing, and will eventually return to nothing. QM postulates that the Universe, under these conditions, is a large quantum fluxuation with no net energy.

In some Big Bang model scenarios, the vacuum should be full of relic neutrinos (about 100 neutrinos in cubic centimeter) with average speed 700 km/sec estimated for neutrinos with 0.4 eV rest mass - i.e. less than the escape velocity from the surface of the Sun. Such neutrinos therefore may be expected to have accumulated in gravitational potential wells. Weiler estimated that the density of relic neutrinos in our own galaxy would increase by four orders of magnitude if their mass were 1 eV. Therefore relic neutrinos can form Boltzmann gas with rather complex distribution and behavior.

The decay rates trend down BEFORE the flare. Why isn't this questioned as some unknown outside influence on both the decay samples and the sun, causing the flares? Since the slowest points seemed to coincide with the flare activity, ending the reduction cycle in the rate of decay.
It’s also consistent with the observation that being closer to the sun, assuming a North American winter, causes an increase in decay rates by virtue of an increase in energy availability from the sun by proximity.

If a particle possesses neither mass nor energy it doesn't exist. Neutrinos exist and certainly have energy. Whether or not they also have mass has been a subject of extensive debate recently. The latest consensus is that they appear to, but not much.

If this effect can detectibly reduce the decay rate of radioactive elements at 1 AU, has anyone considered what this could be doing to radioactive elements in the core of the sun, and how this effects our understanding of solar aging?

I agree with (a) and (b) but what determines (c), the half-life? I have offered my theory in earlier postings here, I would like to hear the Standard Model's reason.

Here you go.
http://www.period...ife.html The stablity of the isotope. The more stable, the longer the half life, or lack of half life. The less stable, the shorter the halflife.

Stability is a factor, but there has to be a trigger also. I believe neutral neutrino radiation is this trigger. What is the trigger in the Standard Model?

My knowledge of radioactive decay isn't extensive, but from what I remember, the arrangement of neutrons and protons within the nucleas determine the stability due to the weak nuclear force (beta decay), strong nuclear force (alpha decay, spontaneous fission), and then there are a few rarer types of decay which I think are a combo of the two due to the extremes under which the isotopes are created.
That's from memory and I think I may be wrong in one or two places up there but from recollection it is the nuclear forces that govern half-life and decay.

There is a very good reason why they don't all evaporate at the same time and that is because they are heated unevenly. Certainly you aren't claiming that temperature plays a role in radioactive decay are you? Something does, what is it?

If you were to extrapolate this to decay you'd see a continuous emission and re-enrichment process occuring, which doesn't occur.

After stellar nucleosynthesis could you explain the trigger that cause radioactive decay here on earth?
Also I fail to see the connection between stellar nucleosynthesis and radioactive decay. One is the putting together the other is the breaking apart.

You should explain, why solar flares are slowing the radioactive decay, not accelerating.

If I am not mistaken solar flares are actually cooler spots on the surface of the sun. Lower temperature, less fusion, less neutrino radiation leads to slightly lower decay rates here on earth.

We still have no method (except the approximations of lattice QCD) to solve the QCD equations of motion for the nucleus. These equations won't be easier to solve when we have to additionally consider the influence of solar neutrinos. An alternative explanation of radioactive decay by solar neutrinos only would not simplify things.

Couldn't this be tested pretty easily?
Like, send some satellite with some radioactive material to the far end of the solar system away from the sun, and see what the decay rate is compared to the earth? Or is it not that simple?

By the way, which kind of decay is variable ? alpha, beta or gamma ?
