Radiocarbon dating decay

To see how we actually use this information to date rocks, consider the following: Usually, we know the amount, N, of an isotope present today, and the amount of a daughter element produced by decay, D*.

Cuvier established amongst the scientific community the fact of extinction.

The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.

Simulation of many identical atoms undergoing radioactive decay, starting with either 4 atoms per box (left) or 400 (right).
