Fraction Modern is a measurement of the deviation of the C is also affected by natural isotopic fractionation.
Fractionation is the term used to describe the differential uptake of one isotope with respect to another.
At the present time, for a 1 milligram sample of graphite, this limiting age is about ten half-lives, or 60,000 years, if set only by the sample size.
However, limiting ages or "backgrounds" are also determined by process blanks which correspond to the method used to extract the carbon from the sample.
In the process of disintegration, the atom gives off radiation (energy emitted in the form of waves).
