Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. Uranium-lead dating can be used to find the age of a uranium-containing mineral. Uranium-238 decays to lead-206, and uranium-235 decays to lead-207.Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes

What does the radiometric dating method use to determine age?

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.
