Hereafter these isotopes will be referred to as 12C, 13C, and 14C.14C is radioactive and has a half-life of 5730 years.Transform the radiocarbon ages into calendar dates using the calibration program CALIB (you can see this and other programs at: New Zealand The laboratory number is a unique identifier given to each radiocarbon sample.Three isotopes of carbon are found in nature; carbon-12, carbon-13 and carbon-14.Carbon-12 accounts for ~99.8 % of all carbon atoms, carbon-13 accounts for ~1% of carbon atoms while ~1 in every 1 billion carbon atoms is carbon-14.
The New Zealand numbers are part of the New Zealand Archaeological Association Site Recording Scheme.
