The atoms of crystalline solids, such as pottery and rock, can be altered by this radiation.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.However, paleoanthropologists rarely use it to date sites more than several million years old.rock, soil, and clay produce constant low amounts of background ionizing radiation.Over the second half-life, of the atoms remaining decay, which leaves of the original quantity, and so on.

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.

The methods that are used depend on the presumed age of the site from which they were excavated.
