For a century, the radioactive decay of unstable elements into more stable ones has been used as a natural clock to estimate the age of earth materials. Even the solar system has been dated using one of these systems, by measuring the amount of a decaying element and Greensborough girls com au it to the amount of its stable decayed daughter material Radiometric dating problems in Australia meteorites.

Stimulating these mineral grains using either light optically stimulated luminescence or infrared stimulated luminescence dating or heat thermoluminescence dating causes a luminescence al to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral. This technique has established a known sequence of Radiometric dating problems in Australia from dated layers found all around the world.
