There is no RationalWiki without you. We are a small non-profit with no staff — we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have decayed. Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy. The time that it takes for half of a sample to decay is known as the half life of the isotope.

Some isotopes have half lives longer than the present age of the universe , but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.

Various elements are used for dating different time periods; ones with relatively short half-lives like carbon or 14 C are useful for dating once-living objects since they include atmospheric carbon from when they were alive from about ten to fifty thousand years old.

Longer-lived isotopes provide dating information for much older times.

Radioisotope dating equation

The same is true regarding gravitational, magnetic, and electric fields, as well as the chemical state in which the atom resides. In this analogy , the apples would represent radioactive, or parent, atoms, while the oranges would represent the atoms formed, the so-called daughters. If you prefer to suggest your own revision of the article, you can go to edit mode requires login.

The most widely used radioactive cosmogenic isotope is carbon of mass 14 14 C , which provides a method of dating events that have occurred over roughly the past 50, years. Thank You for Your Contribution! In attempting to date Mt.
