Radioactive dating is carried out with substances which were formed at some unknown point in the past and contained a known proportion of a radioactive isotope of some element. Radioisotopes decay into other elements at a fixed and known rate. So, if you know how much of the radioactive isotope is still left in the sample, then you can work out how long it would have taken for the rest to have decayed into other elements. That gives the age of the sample.

My nerdy brother wants to start a radioactive dating website! The use of radiometric, or radioactive, dating was initiated in 1907 by Bertram Boltwood.
To fully explain radioactive decay you need quantum mechanics.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
Carbon Dating
Radioactive dating estimate the age of rocks.
Carbon-14 is an example of radioactive dating.
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
Carbon dating
Radioactive dating helps geologists determine the age of rocks and minerals by measuring the amount of radioactive isotopes present and their decay products. This information can be used to establish the age of Earth, study the history of geomorphic processes, and analyze the timing of geological events.
Radioactive dating can be used to estimate the absolute age of an object.
