Radiocarbon Dating Shell, Coral, and CaCO3
According to scientific studies, shellfish obtain organic carbon from marine or terrestrial plants and inorganic carbon from ocean water bicarbonate, atmospheric carbon dioxide, or freshwater bicarbonate. Send your tracking number to lab radiocarbon. We have applied the new steps, screening and separation, on standard and archaeological examples and our initial results suggest that it is successful and reproducible.

The most common contaminants of shell samples for radiocarbon dating are those that are caused by isotopic exchange and recrystallization. Shells are often sent to accelerator mass spectrometry AMS labs for radiocarbon dating.REGISTER TO VIEW
