Radiocarbon dating is a method of determining the age of an object explaining the principle of carbon dating organic material Carbon is one of the major building block for organic material, mainly in stable form of C12 and unstable form of C I asked this in the religious section, Dating is done using the principle of half lives.

The estimated value, parts per mil, yields an adequate correction only if the animal never consumed C4 plants. The very old samples have such low radioactivity that they cannot be distinguished reliably from the background radiation. Targets tuned to different atomic weights count the number of c12, c13, and c 14 atoms in a sample.

The unstable carbon gradually decays to carbon at a steady rate.

This provides a value for the background radiation, which must be subtracted from the measured activity of the sample being dated to get the activity attributable solely to that sample's 14 C.

The half-life is the time required for half of the original sample of radioactive nuclei to decay. However, their association with cultural features such as house remains or fireplaces may make organic substances such as charcoal and bone suitable choices for radiocarbon dating.
