Radiocarbon dating and thermoluminescence use shane kippel dating
Radiocarbon dates can be obtained from many types of organic material including charcoal, shell, wood, bone and hair.The amount of carbon dioxide in the living organism is equal to that in the atmosphere.
Very few artifacts recovered from an archeological site can be absolutely dated.
When the organism dies, the carbon 14 (C14) atoms disintegrate at a known rate, with a half-life of 5,700 years.
It is possible then to calculate the date of an organic object by measuring the amount of C14 left in the sample.
This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.
