How to alter carbon 14 dating

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.

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.

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.

Typically, a Master's Degree in chemistry is required because of the extensive lab work.
