Radiocarbon dating is simply a measure of the level of C isotopes in the atmosphere can vary.This is why calibration against objects whose age is known is required (14).

The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.Stone and metal cannot be dated but pottery may be dated through surviving residue such as food particles or paint that uses organic material (8).
