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

The raw radiocarbon date of any sample can then be converted to true date by using this calibration table.

This calibration step eliminates any concern about fluctuations in historic radiocarbon to stable carbon ratios or decay rates.

Animals (and humans) get their carbon atoms primarily from what they eat (i.e., plants).

date of organic material - but an approximate age, usually within a range of a few years either way.

(This, in turn, is caused by variations in the magnetic fields of the earth and sun, for example.) Although the ratio of radiocarbon to stable carbon in the atmosphere has varied over time, it is quite uniform around the globe at any given time because the atmosphere mixes very quickly and constantly.

Plants obtain all their carbon atoms from the atmosphere.

When an organism dies (whether plant or animal) its intake of carbon atoms ceases.
