Why is there so much C14 in Cambrian diamons if they are so old?

Question

Confirmation that there is in situ carbon-14 in diamonds has now been reported in the conventional literature.3 R.E. Taylor of the Department of Anthropology at the University of California–Riverside and of the Cotsen Institute of Archaeology at the University of California–Los Angeles teamed with J. Southon at the Keck Accelerator Mass Spectrometry Laboratory of the Department of Earth System Science at the University of California–Irvine to analyze nine natural diamonds from Brazil. All nine diamonds are conventionally regarded as being at least of early Paleozoic age, that is, at least several hundred million years old. So, if they really are that old they should not have any intrinsic carbon-14 in them. Eight of the diamonds yielded radiocarbon “ages” of 64,900 years to 80,000 years. The ninth diamond was cut into six equal fragments, which were each analyzed. They yield essentially identical radiocarbon “ages” ranging from 69,400 years to 70,600 years. This suggests the carbon-14

Answer 1

Coal (and subsequently diamonds) often has uranium deposited along with it. I don't know the reason but this is frequently found and therefore a fact. This uranium frequently contaminates the coal (and also subsequently diamonds) for radiation readings. It is a much different process from merely taking a piece of wood or cloth, cleaning it, and carbonizing it in a lab and then taking C14 readings. It is more accurate with regard to coal (and diamond) deposits to check uranium-lead isotope ratios.

Sorry, but Berayshet (Genesis) is still poetry, not science.
