PDB refers to the Cretaceous belemnite formation at Peedee in South Carolina, USA.

This nomenclature has recently been changed to VPDB (Coplen, 1994).

The resultant ages are termed “normalized”, meaning the measured activity is modified with respect to -25 o/oo (per mille) with respect to VPBD.

The correction factor must be added or subtracted from the conventional radiocarbon age.*****Beta Analytic’s fees already include δ13C measurements in conjunction with C14 analysis.

The evaluation of radiocarbon data and the historical development of radiocarbon dating as a method that aids in archaeological studies are also discussed.

Please email the lab for the rates.*****In order to provide radiocarbon determinations that are both accurate and precise, it is necessary to correct for “isotopic fractionation” using the stable isotopes 13C and 12C.The δ13C value for a sample can yield important information regarding the environment from which the sample comes or the mixtures of materials used to produce it because the isotope value of the sample reflects the isotopic composition of the immediate environment.
