Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. 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 it can be used to date a wide range of natural and man-made materials. The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating. By establishing geological timescales, radiometric dating provides a significant source of information about the ages of fossils and rates of evolutionary change, and it is also used to date archaeological materials, including ancient artifacts.
Uses of Radioactive Isotopes
Mankind has made some incredible scientific discoveries and radioactive dating is one of them. Also called radiometric dating, this technique is used by geologists and physicists to determine how old a substance is. We have learned some fascinating history from dating rocks and fossils, thanks to dating. Radioactive dating has an important function, history and many interesting features. There are two main types, both of which have their limitations.
