Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time. This constant probability may vary greatly between different types of nuclei, leading to the many different observed decay rates. The radioactive decay of certain number of atoms mass is exponential in time.

Equipping youth pastors, parents, and students with Biblical answers for evolutionary teaching in public schools. Carbon dating assigns ages to once-living materials such as wood, bone, teeth, and shells. Evolutionary researchers do not use it to age-date rocks. It begins by measuring the ratio of radioactive versus stable versions of an element.

Carbon dating , known also as radiocarbon dating , is a method for determining the age of an object containing organic material by using the properties of radionuclide carbon In spite of this short half-life compared to the age of the earth, carbon is a naturally occurring isotope. Its presence can be explained by the following simple observation.
