Radiometric dating , radioactive dating or radioisotope dating is a technique which is 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 decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.

What is Radioactive Dating? - Definition & Facts
Lesson Transcript. Discover how scientists determine the age of fossils, rocks, and other geologic phenomena by using the known half-lives of isotopes within each specimen, a technique known as radioactive dating. Radioactive Dating Ever wonder how scientists concluded the age of the earth to be about 4.
Radioactivity Defined Elements occur naturally in the earth, and they can tell us a lot about its past. The Half-Life Isotopes decay at a constant rate known as the half-life.

Radiocarbon Dating Since all living things contain carbon, carbon is a common radioisotope used primarily to date items that were once living. Lesson Summary So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives.

How Does Radiometric Dating Work? - Ars Technica
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it. For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products in this case strontium. The object's approximate age can then be figured out using the known rate of decay of the isotope.
For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.
As that interestingly sounds27.03.2020|Reply
On mine the theme is rather interesting. I suggest you it to discuss here or in PM.29.03.2020|Reply
