Both are, however, 'children' of the same parent -- the Zero Point Energy.Because of this, and because the speed of light is in the numerator of every reduced radio decay rate equation, any changes in the speed of light are indicating changes in atomic decay rates. Importantly, the original short half-life elements were also a contributor and they have gone now.
I emailed you about this topic a year or two ago, and I've since taken a class in radioisotope chemistry at UCI.
As a result I was using some of my texts to examine the decay of Americium 241 and noted the naturally occurring decay chains for U235, U238 and Th232, as well as the fully decayed chain for Pu241.
My thought is, can the relative natural abundances of these chains' terminal products (Pb208,207, and 206) be used to calculate an initial abundance and time frame for the original atomic abundances of the parent isotopes which could be compared to the predictions of Willie Fowler regarding stellar nucleogenesis processes. Thanks again for all your interesting and informative web postings and work.
Setterfield: I believe that it is possible to determine the initial ratios of the parent elements in the various chains.

Isn’t dendrochronology accurate for checking radiocarbon dating?

Setterfield: Atomic decay rates do not depend on the speed of light.
It is through this mechanism that the radiometric age of the universe is usually calculated as being on the order of ten billion years.
Professor Fowler did exactly this and has maintained his calculated radiometric age for the universe at about 10 billion years, with which I am basically in agreement.
Interestingly, using these sorts of ratios, one piece of moon rock dated as being 8.2 billion years old, to the amazement of the dating laboratory involved.
