Formula for carbon dating
After all, this what the archeologist guessed in their published books.
Some believe trees are known to be as old as 9,000 years. A lot of people doubt this claim for various good reasons I wont go into here.
Before the nuclear age, the amount of radiocarbon in the environment varied little in the span of a century.
In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.
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.
This skews the 'real' answer to a much younger age.And this big sequence is then used to 'correct' C14 dates. (3.) Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question.(4.) Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.If you have any more questions about it don't hesitate to write.(2.) I just listened to a series of lectures on archaeology put out by John Hopkins Univ.
