It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.

In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).

Radiocarbon dating is simply a measure of the level of C isotopes in the atmosphere can vary.

This is why calibration against objects whose age is known is required (14).

It is presumed that the proportion of atmospheric C is the same today as it was in 1950 (10), (11) and that the half-life remains the same.

If a radioactivity level comes back as half of what would have been expected if the organism had died in 1950, then it is presumed to be 5,730 years before 1950.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.AMS works slightly differently; it converts the atoms of the sample into fast-moving ions so that they become charged atoms.
