Radioactive Decay Article Summary

Image found here.
According to Brian Thomas' article, radioactive elements do not decay at steady, predictable rates.  Several laboratories and universities found that some decay rates, specifically of silicon-32, altered with the seasons.  After the matter was looked into more in depth it was found that solar neutrinos from the sun are the most probable cause for this fluctuating decay rate.  Though little else is known about the why's and how's of this new puzzle it's a certain fact that this discovery rather shakes the foundations of rock dating.  If the decay rates of these radioactive isotopes can be effected by solar flares how are we able to tell just exactly how old something is?  Food for thought.



P.S. I've made an entire prezi and tumblr post for radioactive decay.  Go check it out!
