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.

In AMS, the filiamentous carbon or "graphite" derived from a sample is compressed into a small cavity in an aluminum "target" which acts as a cathode in the ion source.

The surface of the graphite is sputtered with heated, ionized cesium and the ions produced are extracted and accelerated in the AMS system.

There are two situations that limit an age; the first is that the measured Fm is smaller than that of the corresponding process blank measured in the same suite of samples on the AMS.

If this is the case, then the reported age will be quoted as an age greater than the age of the process blank. The typical background age for organic combustions is 48,000 years and for inorganic carbon samples, 52,000 years.

The final reported error is the larger of the internal or external errors.

The limiting age is then calculated as -8033 * ln(2sigma) and rounded according to conventions outlined above.

Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts.

Ages are calculated using 5568 years as the half-life of radiocarbon and are reported without reservoir corrections or calibration to calendar years.

For freeware programs, we suggest that you look at the following web site for a list of programs that will calibrate radiocarbon results to calendar years (including making reservoir corrections).[ Radiocarbon-Related Information Sources] The error in the age is given by 8033 times the relative error in the Fm .
