Each radioactive isotope decays by a fixed amount, and this amount is called the half-life.

Libby was awarded the Nobel Prize in chemistry for his work in 1960.

Carbon dioxide in the atmosphere contains a constant amount of carbon-14, and as long as an organism is living, the amount of carbon-14 inside it is the same as the atmosphere.
