Stone and metal cannot be dated but pottery may be dated through surviving residue such as food particles or paint that uses organic material (8).

There are a number of ways to enter into a career in studying radiocarbon dating.

AMS counts the quantity of C isotope is constantly formed in the upper atmosphere thanks to the effects of cosmic rays on nitrogen-14 atoms.

It is oxidised quickly and absorbed in great quantities by all living organisms - animal and plant, land and ocean dwelling alike.

There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.

The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.

Though their initial calculations were slightly incorrect thanks to the contaminants of extensive nuclear testing of the age, scientists soon discovered the error and developed methods that were more accurate, including a date of calibration to 1950.When an organism dies, it stops absorbing the radioactive isotope and immediately starts decaying (7).
