#### Use of radioisotopes in dating

since the 1950s, geologists have used radioactive elements as natural "clocks" for. carbon-14 dating: what does it really tell us about the age of the earth? the age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to closure temperature. dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age.
## Radioisotopes used in radiometric dating

for this reason, icr research has long focused on the science behind these dating techniques. dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques. radiometric dating is also used to date archaeological materials, including ancient artifacts.
