Plants and animals absorb both C-12 and C-14 in the course of their natural lifetimes simply by carrying out these basic functions.

When they die, they cease to consume them, and the isotope of C-14 begins to revert back to its Nitrogen state at an exponential rate due to its radioactive decay.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.

Here on Earth, Carbon is found in the atmosphere, the soil, the oceans, and in every living creature. C-12, so-named because it has an atomic weight of 12 – is the most common isotope, but it is by no means the only one.

Carbon 14 is another, an isotope of carbon that is produced when Nitrogen (N-14) is bombarded by cosmic radiation.

How do scientists know how old an object or human remains are?

What methods do they use and how do these methods work?

Radiocarbon enters the biosphere through natural processes like eating and breathing.Carbon-14 is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.
