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.Throughout the life of an animal or plant, the amount of C14 is perfectly balanced with that of its surroundings. The C14 in a dead organism slowly decays at a known rate: its "half life".The half-life of an isotope like C14 is the time it takes for half of it to decay away: in C14, every 5,730 years, half of it is gone.If something carbon dates at 7,000 years we believe 5,000 is probably closer to reality (just before the flood).Robert Whitelaw has done a very good job illustrating this theory using about 30,000 dates published in Radio Carbon over the last 40 years.Libby, the discoverer of the C14 dating method, was very disappointed with this problem.He understood that archaeological artifacts were readily available.

She says this is ok so long as you take into account the correction factors from dendrochronology.Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.This standard content of C14 can then be used for wood not associated with a historically documented date.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.
