AMS works slightly differently; it converts the atoms of the sample into fast-moving ions so that they become charged atoms.By applying magnetic and electrical fields, the mass of these ions is measured and the accelerator is used to remove ions that might contaminate the dating.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).Archaeologists had used Relative Dating methods to calculate their reigns.

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.The next big step in the radiocarbon dating method would be Accelerated Mass Spectrometry which was developed in the late 1980s and published its first results in 1994 (3).This was a giant leap forward in that it offered far more accurate dates for a far smaller sample (9); this made destruction of samples a far less delicate issue to researchers, especially on artefacts such as The Shroud of Turin for which accurate dates were now possible without damaging a significant part of the artefact.
