Examples of how to use “radiometric dating” in a sentence from the Cambridge Dictionary Labs.
Carbon Dating Carbon dating to determine the age of fossil remains In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon dating is based upon the radiometric dating of 14C, a radioactive example of carbon with a relatively long half-life years. Returning to our example of carbon, knowing that the half-life of 14C is years, we can use this to find the constant, k.
The half-life for 14C is approximately years, therefore the 14C isotope is only useful for dating fossils up to about 50, years old. For example, the radioactive isotope potassium decays to argon with a half life of 1. Other isotopes commonly used for dating include uranium half-life of 4.
