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.
(They conveniently forget to mention that the tree ring chronology was arranged by C14 dating.
The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which (using the bristlecone pine).
Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.Despite this she continually uses the c14 dates to create 'absolute' chronologies.She says this is ok so long as you take into account the correction factors from dendrochronology.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.
Furthermore, if a sample has been contaminated, scientists will know about it.
