Web6 jan. 2011 · Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements. The starting isotope is called the parent and the end-product is called the daughter. The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life. WebUranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium-234 (234 U) and uranium-238 (238 U). It is one of several radiometric dating techniques exploiting the uranium radioactive decay series , in which 238 U undergoes 14 alpha and beta decay events on the way to the stable isotope …
