Carbon dating process

carbon dating process-83

When an organism dies, it stops absorbing the radioactive isotope and immediately starts decaying (7).

As previously mentioned, the half life of the C isotope is 5,730 years - this means that it takes 5,730 years to reach half the radioactivity that the organism had at the point of death, another 5,730 years to reach 25% radioactivity it had at the point of death and so on.

The sample passes through several accelerators in order to remove as many atoms as possible until the C pass into the detector.

These latter atoms are used as part of the calibration process to measure the relative number of isotopes (9).

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