This method involves comparing the ratio of radioactive isotopes in the fossil to that. Radiometric dating is the determination of the date at which materials were formed by analyzing the decay of radioactive isotopes that were incorporated into the.
Major radioactive elements used. Other methods of dating are used for non-living things. The isotopes that are searched for radioisotopes used in radiometric dating generally radioactive ones. What Is Radioactive Dating? Radioactive isotopes, or radioisotopes, can be used to estimate the ages of not only of rocks, but also of fossils and artifacts made.
