I was also challenged about decay rates, so I found an article on CMI by john woodmorappe entitled
billion-fold acceleration demonstrated in laboratory.

john woodmorappe is a grade school teacher in Chicago public schools using a fake name.

His "article" cited other sources, including a certain grade school teacher from Chicago, himself. But he completely misinterprets the results and his conclusion is nothing less than insane fantasy.

"Conclusion

This exciting demonstration that isotopic 'clocks' can be accelerated at least a billion-fold is good news to creationist scholars. It raises fundamental questions about the temporal stability of isotopic 'clocks'. What else have we failed to consider in terms of the physics of radioactive decay? The myth of the virtual invincibility of radioactive decay to external forces has been decisively shattered, and the door to further research has now been swung wide open."

The finding that "isotopic 'clocks' can be accelerated at least a billion-fold" is not good news, when that acceleration occurs when heavy elements are heated to the point of plasma is far from good news to "creationist scholars" Its like saying that the ratio of of carbon 14 to carbon 12 can be changed by burning the sample to ash and reconstituting it with a star trek replicator set on "age the sample"

The article DOES not in any way address the problem of carbon 14 dating.

If God created everything in 6 days, isn't it more logical that he simply created all the fossils and biological remains with ratios of isotopes that make them appear to be the the ages that we detect rather than heating them to the point that the atomic bonds start to break down, but only for the isotopes he wants to age while presumably leaving alone the other elements in the rocks such as silicon then magically cooling them and putting back with nothing changed except isotope ratios. Yes Steve, I know that sounds awkward. But john woodmorappe's idea is very awkward.
