Radiometric dating

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its . 6 Oct Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.

Ever wonder how scientists concluded the age of the earth to be about 4. Or even how they dated the age of Pompeii bread?

Well, scientists are able to answer all of these wondrous questions and more by use of a process called radiometric or radioactive dating. Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale.

Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils and other substances. Elements occur naturally in the earth, and they can tell us a lot about our Earth's past. Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.

The carbon it contained at the time of death decays over a long spell of time. By measuring the amount of carbon left in dead native material the approximate circumstance since it died can be worked out.

After example, in , two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain. Some rocks contain traces of uranium. Uranium has a very long half-life and so by measuring how much uranium is formerly larboard in a rock its approximate age can be worked out. Back to Radiation for life indicator.

Some isotopes, however, decay slowly, and several of these are used as geologic clocks. The parent isotopes and corresponding daughter products most commonly used to. Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
