You're just making me drag you kicking and screaming through the obvious. So be it.
Carbon 14 shows the usual inverse exponential decay curve. Because of the contamination factors already mentioned, and you have done nothing to explain why such should not be considered, the decay curve does not extend to a zero floor. It has a "noisy" floor, just as your local radio spectrum has a floor of static around the spikes of radio station signal.
From article: ... Most of these papers acknowledge that most of the 14C in the samples studied appear to be intrinsic to the samples themselves, and they usually offer no explanation for its origin.
"Intrinsic to the samples" means "not introduced in excavation or subsequent handling," which is another way to get contamination. It means that the carbon is thoroughly imbedded in the sample. Ground water or atmospheric contamination will produce this result and is not eliminated thereby.
Do the ICR charlatans not know this? Of course they know this! They're hoping most of the dummies out here don't know this.
Does that help any?
nice long-winded post, vade. But where is the proof of their mis-conduct? Lets see it.
