Across all radioactive dating methods there is an assumption of a half-life exponential rate of deteriation. There are many rates they could have used , but the half-life rate is the perfect exponential rate only in a perfectly random environment. ie if you put a geiger counter next to a deteriating rock, the randomness should show no patterns whatsoever. However in trying to use this to create pure random numbers they discovered that there were patterns in the decay , when decay is supposed to be prefectly randomly uniform. Thus the whole assumption of the "half-life" is incorrect which basically ruins the entire methodology of rock dating.
Furthermore the patterns that were observed seem to be based on solar winds, the stronger the solar wind the faster the decay. A strong magnetic field like today's magnetic field deflects the solar wind. But what if the magnetic field was weaker in the past, this would mean that the solar wind was stronger on earth, and rocks would have decayed faster. It has been recorded that the earth went through continuous weakened magnetic fields whenever the magnetic poles reversed, which basically means that rock decay rates were never constant as is currently alleged, but went through periods of acceleration during these pole reversals. Other than the pole reversals, decay rates would have generally been stronger than today because of the general recorded weaker magnetic fields in past periods.
The strange case of solar flares and radioactive element
August 23, 2010 BY DAN STOBER
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.
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.
Direction and intensity of Earth’s magnetic
field at the Permo-Triassic boundary:
geomagnetic reversal recorded by the
Siberian Trap Basalts, Russia
4. August 2003
Detailed studies of palaeodirectional and absolute palaeointensity patterns of geomagnetic reversals are scarce and are restricted to the Cenozoic so far. In order to verify or reject concepts developed on the basis of this dataset, reversal records which
occurred in the more distant geological past of the Earth are needed. This work presents the results obtained from the Siberian Trap Basalts (Russia) which are coeval with the Permo-Triassic boundary (250 Ma). The sequence yields the by far oldest hitherto studied detailed record of a geomagnetic transition from reversed to normal polarity and provides new insights in transitional field behaviour.
