I found the example that I was thinking of. Good old Answers in Genesis, they still do not seem to understand how a change that only occurs in an extreme plasma state, so we are beyond merely vaporizing the crust, is evidence against them:
Billion-Fold Acceleration of Radioactivity Shown in Laboratory
" More recently, bb
decay has been experimentally demonstrated in the rhenium-osmium (187Re-187Os) system. (The Re-Os method is one of the isotopic ‘clocks’ used by uniformitarian geologists5
to supposedly date rocks.) The experiment involved the circulation of fully-ionized 187Re in a storage ring. The 187Re ions were found to decay to a measurable extent in only several hours, amounting to a half-life of only 33 years.6
This represents a staggering billion-fold increase over the conventional half-life, which is 42 Ga! (Ga = giga-annum = a billion (109) years)."
Yes, if Rhenium is put into a state that would not even occur at the center of the Sun it will have a greatly increased decay rate. And this helps them how?
