For radiocarbon dating to be possible, the material must once have been part of a living organism.
This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
Carbon dating is not perfect, but it can give you a rough idea. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years. Both U-238, and C-14 (radiocarbon, for carbon dating) are used to estimate the age of certain types of matter.
These atoms decay, and from the amount of atoms remaining, an estimate of the age can be made.
By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. Radioactive elements were incorporated into the Earth when the Solar System formed.
