What type of radiation is used in carbon dating

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.

This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.These are released as radioactive particles (there are many types).So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.

The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time.
