The decay events for each sample are measured over a week.

The results from the liquid scintillation spectrometer are carefully analysed and provide a radiocarbon age for the sample.

The silica glass vials are loaded into the liquid scintillation spectrometer.

The C-14 atoms present in the benzene decay at a certain rate.

Professor Tom Higham is director of the Oxford Radiocarbon Accelerator Unit at Oxford University and Principal Investigator for the Palaeo Chron Project.

Then a stream of oxygen is added into the system and the sample is combusted.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.It is during this stage that the carbon present in the sample is converted into carbon dioxide.The carbon dioxide is collected and bubbled through various chemicals in the line, which purify it, and the amount of carbon dioxide that has been collected is measured.
