nuclear decay rates and solar activity



wavewatching | Radioactive decay is supposed to be the ultimate random process, immutably governed by an element's half life and nothing else. There is no way to determine when a single radioactive atom will spontaneously decay, nor any way to speed-up or slow down the process. This iron clad certainty has always been the best argument of opponents to conventional nuclear fission power generation, as it means that the inevitable nuclear waste will have to be kept isolated from the biosphere for million of years (notwithstanding recent research attempts at stimulated transmutation of some of the longer lasting waste products.)

There is a video talk on this phenomenon. It takes some patience to sit through, but gives a more complete picture in explaining how these observed patterns can be correlated to the the Sun's core activity with surprising accuracy. The evidence for the reality of this effect is surprisingly good, and that is rather shocking. It does not fit into any established theory at this time. Fist tap Dale.
