Calculating Half-Life - Chemistry LibreTexts

Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life ( years). While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms.

Carbon 14 Dating: What assumptions should we take?

Oxidizable carbon ratio dating is a method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35, years old. The method is experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating.

Carbon 14 Dating

The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. The carbon decays with its half-life of 5, years, while the amount of carbon remains constant in the sample.

Dating Methods Using Radioactive Isotopes

A critical assumption used in carbon dating has to do with this ratio. It is assumed that the ratio of 14 C to 12 C in the atmosphere has always been the same as it is today (1 to 1 trillion). If this assumption is true, then the AMS 14 C dating method is valid up to about 80, years.

Absolute Geologic Time

In the atmosphere, cosmic rays smash into normal carbon 12 atoms (in atmospheric carbon dioxide), and create carbon 14 isotopes. This process is constantly occurring, and has been for a very long time, so there is a fairly constant ratio of carbon 14 atoms to carbon 12 atoms in the atmosphere.
