Radiometric dating is a method of establishing how old something is – perhaps a wooden artefact, a rock, or a fossil – based on the presence of a radioactive isotope within it.

What premise does radiometric dating rely on?

Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. The decay rate is referring to radioactive decay, which is the process by which an unstable atomic nucleus loses energy by releasing radiation.

What is the principle of radiometric dating?

To be more specific, it is a method used to date rocks based on the known decay rate of radioactive isotopes that are found within the rocks. This decay rate is referring to radioactive decay, which is the process by which an unstable atomic nucleus loses energy by releasing radiation.
