The creation rate of C14 (and so the proportion in the atmosphere) depends on the suns activity - so a lot of dates which assumed a constant rate are known to be wrong.We can now calibrate this out by looking at C14 in tree rings of a known age - but the charge of "C14 dates are wrong" is used by nutters (sorry creationists) either deliberately or in ignorance.

What is their proposed mechanism for these abundances changing?There are a few effects that can alter radioactive half-lives, but they are mostly well understood, and in any case would not materially affect the radiometric dating results.That is, the analysis of the isotopic and chemical composition of the sample has far greater uncertainty than any uncertainty in the decay rate itself.Electron capture requires that there be an electron in the vicinity of the nucleus, so its activity depends strongly on the configuration of the electron cloud, which depends on the chemical state.In fact, it is possible to shut down electron capture completely‚ÄĒsimply ionize the substance so that there are no electrons nearby.

There is another effect that takes place in the "electron capture" type of Beta decay.
