Scientific definition of radioactive dating

Isotopes decay at a constant rate known as the half-life.The half-life is the amount of time it takes for half of the atoms of a specific isotope to decay.Since all living things contain carbon, carbon-14 is a common radioisotope used primarily to date items that were once living.Carbon-14 has a half-life of approximately 5,730 years and produces the decay product nitrogen-14.Radiocarbon dating was used to identify a forged painting based upon the concentrations of carbon-14 detected on the canvas within the atmosphere at the time that the picture was painted.

The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity.Elements occur naturally in the earth, and they can tell us a lot about its past.Carbon, uranium, and potassium are just a few examples of elements used in radioactive dating.Each element is made up of atoms, and within each atom is a central particle called a nucleus.Within the nucleus, we find neutrons and protons; but for now, let's just focus on the neutrons.

Just as in the example with uranium, scientists are able to determine the age of a sample by using the ratios of the daughter product compared to the parent.
