It has always been assumed that decay rates for radioactive decay is constant and not effected by natural processes. But recent discoveries at the Brookhaven Natural Laboratory casts doubt on it. They showed there were statistical discrepencies of measured decay rates published over the years. During a solar flare in 2006 a decay rate of a manganese radioisotope slowed. The test was repeated later with similar results. Then over in Germany it was discovered to occur with radium-226. The culprit was thought to be neutrinos. Another discovery was that the decay rate modulation is in sync with the earths orbit.
Not just the sun, but also supervovae produce a neutrino flux.
So this means what? That apparently there are natural processes that can effect decay rates and therefore change dates from our dating methods. CMI
