Radiocarbon dating new zealand

In just the past 10 years over 25,000 samples have been measured from clients in New Zealand and throughout the world.As well as the AMS facility, the Rafter Radiocarbon Laboratory operates a modern, well equipped sample processing laboratory.We hope it will be of occasional use to radiocarbon users and interested students alike.Copyright 1999 Tom Higham, Radiocarbon Laboratory, University of Waikato, New Zealand (Email: [email protected]).This carbon dioxide becomes incorporated in plants through the process of photosynthesis, and into animals via the food chain.Throughout their lives, trees like Kauri take up 14C from the atmosphere.Radiocarbon dating is one of the main lines of evidence of Polynesian arrival some time between 12.Since the 1950s, when this method was developed, scientists have learnt more about its application in the New Zealand setting.

On average, a particle of 14C will exist on Earth for 8033 years, before it decays, or changes back to 14N by losing an electron.This process of radioactive decay is the basis for the radiocarbon dating method.The 14C atoms rapidly oxidize, and become carbon dioxide (CO2). Radiocarbon dating is the technique upon which chronologies of the late Pleistocene and Holocene have been built.This resource is designed to provide online information concerning the radiocarbon dating method.Lab manager Dr Christine Prior already has bad news for another client – an art authenticator in Hong Kong.
