In other words, the change in numbers of atoms follows a geometric scale as illustrated by the graph below.other carbon isotopes in the same ratio as exists in the atmosphere.

Following death, however, no new carbon is consumed.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.

In the same year, Kurie (Yale) exposed nitrogen to fast neutrons and observed long tracks in a bubble chamber. The mean life time of roughly 8000 years is ideal for dating of reservoirs that are a few decades to a few ten thousand yeas old.For groundwater, this means that C is a widely used tool to establish chronologies for groundwater flow systems and climate records for the Holocene and Pleistocene.It is considered to be the most important tool for age dating of ‘old’ groundwater.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.
