forms of dating that rely upon the fact that electrons become trapped in minerals' crystal lattices as a function of background radiation. the age of the specimen is the forms total radiation received divided by the annual dose of radiation. carbon dating is used to determine the age of biological artifacts up to 50, 000 years old. this technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils ( like those of the dinosaurs alleged to be millions of years old). there are forms of dating artifacts several common radioactive isotopes that are used for dating rocks, artifacts and fossils. the most common is u- 235. u- 235 is found forms in many igneous rocks, soil and sediment. u- 235 decays to pb- 207 with a half- life of 704 million years. due to its forms long half- life, u- 235 is the best isotope for radioactive dating, particularly of older. relative dating before the advent of absolute dating methods in the twentieth century, nearly all dating was relative. the main relative dating method is stratigraphy ( pronounced stra- ti- gra- fee), which is the study of layers of rocks or the objects embedded within those layers.
