radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.
The following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methods carbon 14 is used for this example which was put out by dr hovind dr hovind r1 the atmospheric c14 is presently only 13 of the way to an equilibrium value.

isotope one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties every chemical element has one or more isotopes an atom is first identified and labeled according to the number of protons in its nucleus.
Radiometric dating he question of the ages of the earth and its rock formations and features has fascinated philosophers theologians and scientists for centuries primarily because the answers put our lives in temporal perspective.
