ESR Dating

Abbreviation for electron spin resonance dating, a chronometric dating method based on the accumulated natural radiation damage in crystalline substances such as carbonates and tooth enamel. The method measures the level of radioactive bombardment undergone by tooth enamel by determining the number of electrons that have been knocked out of their energy shells, and subsequently become trapped in crystals of apatite found in tooth enamel.
