Many, many christians who are also scientists support maintstream radiometric dating theory. I can say this with confidence because a considerable majority of Christians worldwide accepts mainstream science and rejects YEC. The one in that article is one who has troubled to explain it.
He doesn't acknowledge that all fossils have been found to have more than expected Carbon-14 still in them, which should have been fully depleted.
Oh dear, you have been sold standard creationist website lie #8545. Do some more research. But not on poisoned wells like ICR and AiG which are designed to spin lies to the uninformed. Look up the real science on this issue. Its generally best to know something about a technical subject before you sound off about it.
I understand that under older technology, background radiation which could be mistaken for C-14, made it impossible to determine the C-14 level below a certain threshold. That's what effectively limited C-14 dating methods to 50,000 years.
Using new technolgoties, (accelerator mass spectrometer) the actual molecules in a sample can be counted, not relying on the radiation for an inferred count. This extends the accuracy of C-14 dating to 90,000 years. However, using the new technique, the amount of C-14 in the fossils were orders of magnitude higher than expected.
Secular scientists examining the fossils say the C-14 appears to be intrinsic to the fossils and no source of contamination to explain the levels has been identified.
Carbon Dating Undercuts Evolution's long ages
There are some on Freerepublic thought that have suggested groundwater contamination. But if fossils are so easily contaminated, what does that say about all the other radiometric dating methods.
