There are several problems that trash the effort to deny radioactive decay series in the ICR "reports" linked by Mr. Swords Guy.
The first obvious failure was
"Unfortunately for the secularist, there are radiohalos formed from what appears to be primordial Po (polonium), rather than Po in the form of daughter isotopes from U decay." (This is the correct link to Creationist Silly Part 1, by the way).
The failure is of course that the creationists merely make the empty assertion without any evidence. This particular creationist fraud has been popular since Robert Gentry's publications in the 1970s. What he, now any later creationist was never ever able to explain was how they could tell the difference between "primordial" Polonium and the regular sort. The entire creationist fantasy is debunked by (PDF)
Collins, Lorence G. "Polonium halos and myrmekite in pegmatite and granite." (1997). Then there is the basic error of the Helium content of zircons promoted by Russ Humphreys. Among the gross errors of fact are that the tested material was removed from very high pressure rock which alters Helium diffusion, and that the silly notion of "accelerated nuclear decay" would have melted the Earth, and slaughtered all life.
Then there is this little horse's gift to the pasture,
"Unfortunately for the secularist, there are serious problems with the uniformitarian view as it is applied to radioactive dating. Recent experimental evidences verify that the decay rates of radioisotopes can vary significantly from the currently accepted values—by as much as 10[SUP]9[/SUP] times faster (that’s 1 billion times faster) when exposed to certain environmental factors." The
"certain environmental factors" happen to be heated to a ionized plasma. That is correct, boys and girls. All we need to do to alter negative beta decay is turn the Earth into a glowing ball of electron free gas.
Sure- no problem.
That was followed by the comparatively minor lie that, "It is particularly interesting that the alpha-decay rates of [SUP]228[/SUP]Th are increased by as much as 10[SUP]4[/SUP] (10,000 times) under conditions which give rise to high pressure waves."
This cited a paper that was refuted by a half dozen later experiments. But even if it was not a failure as science, the "environmental conditions" in this case were a dissolved thorium oxide subjected to ultrasound cavitation.
Sure- no problem. Just liquefy the Earth in a giant blender in an ultrasound machine, and then there might be some effect that cannot be replicated by anyone. (2009.
