The most important archaeological dating method is radiocarbon dating.
It is a technique that can yield absolute dates with accuracy up to approximately 5000 years before present.
The radiocarbon method measures the rate of decay in the C14 of organic matter therefore estimating how long ago death occurred.
Archaeologists can use this method to date bone, teeth, plants, seeds, burned food remains, coprolites, wood, and any artefact that contains organic materials such as an iron axe head (iron cannot be tested using C14) with a wooden handle or a bronze spear with a wooden shaft.
Smaller sample sizes can be accommodated, but please contact us.
N, during which one of the neutrons in the carbon atom becomes a proton.
The industrial revolution has belched hundreds of thousands of tons of carbon gases into the atmosphere increasing the C12 ratio and atomic weapons testing have increased neutron levels.
Thirdly, the environment in which the artefact lies heavily impacts on the rate of decay.
Secondly, the theory behind C14 dating demands that there is the same rate of cosmic production of radioactive isotopes throughout time.We recommend that if at all possible, we take the sample for you.This allows us to discuss the sampling and measurement procedure with you at the time.Organic matter, being porous, can easily be contaminated by organic carbon in groundwater.
This increases the C12 content and interferes with the carbon ratio.Authenticity of the sampling is up-held by a photograph taken together with our unique laboratory reference number for the object.
