Radiocarbon dating jobs
In fact, 14C is forming FASTER than the observed decay rate.
This skews the 'real' answer to a much younger age.
Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
He understood that archaeological artifacts were readily available.
So they tested some of the ring sequences by C14 to put the sequences in the 'right' order.
Once they did that they developed the overall sequence.
(2.) I just listened to a series of lectures on archaeology put out by John Hopkins Univ.by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.This is only because it is well calibrated with objects of known age.The lecturer talked at length about how inaccurate C14 Dating is (as 'corrected' by dendrochronology).The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error.
