Beta analytic inc radiocarbon dating

Radiocarbon dating is one of the most intensively used analyses, as it can place in time organic materials, such as wood, shell, seeds, snail shells, and bones, recovered from archeological sites. Briefly, the samples go through a general clean-up and various pretreatment steps for various types of material.This includes treatment with acid/alkali/acid baths to remove contaminates.All the radiocarbon dates are presented in years before present (B. Radiocarbon is incorporated into various materials by different pathways and this introduces different degrees of isotopic fractionation.Stable carbon isotope ratios (δ13C) are given as per mil (‰) difference from PDB-1 standard ratio and as the corrected radiocarbon age in B. The standard error on an analyzed 13C/12C value is quite small and does not contribute significantly to the combined error on the date.
