This transformation may be accomplished in a number of different ways, including radioactive decay, either by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous fission, and electron capture.
any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product.
It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.
Nuclides useful for radiometric dating have half-lives ranging from a few thousand to a few billion years.
Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts.
Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.
While the moment in time at which a particular nucleus decays is random, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques.
After one half-life has elapsed, one half of the atoms of the substance in question will have decayed.
But new research by creationists has revealed a large number of problems with radiometric dating.
