So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

Radiocarbon dating, also known as carbon-14 dating or simply carbon dating, is a method used to determine the age of organic material by measuring the radioactivity of its carbon content.

So, radiocarbon dating can be used to find the age of things that were once alive, like the Iceman.

Carbon-14 is continually being created in the atmosphere due to the action of cosmic rays on nitrogen in the air.

Carbon-14 combines with oxygen to create carbon dioxide.
