Ams dating definition

The final reported error is the larger of the internal or external error, propagated with errors from the normalizing standards and blank subtraction.

It should be noted that the reported error is an estimate of the precision (repeatability) of measurement for a single sample.

The Fraction Modern corrected for δC of a sample 10 separate times over the course of a run.

Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.

Since atmospheric carbon 14 arises at about the same rate that the atom decays, the Earth's levels of carbon 14 have remained constant.

This correction is performed as follows: $$Fm_ = Fm_ ( Fm_ - Fm_b)\frac$$ Where \(M\) is sample mass, and \(M_b\) and \(Fm_b\) are the mass and Fm of the blank.

Fraction Modern is a measurement of the deviation of the C is also affected by natural isotopic fractionation.
