| Résumé≠ | Electron spin resonance (ESR) dating is a chronometric method that determines the age of bones, teeth, mollusk shells, and sediments by measuring accumulated radiation-induced unpaired electrons. Developed by Michael Aitken in the 1980s, ESR detects free radicals trapped in mineral crystal structures. Unlike luminescence techniques that require heating or light exposure, ESR directly measures paramagnetic defects, making it particularly valuable for dating dental and skeletal remains that are inaccessible to other methods. | Thermoluminescence (TL) dating is a chronometric technique that determines the age of pottery, ceramics, and sediments by measuring light emitted when heated to high temperatures. Pioneered by Michael Aitken in the 1960s, it quantifies the accumulated radiation dose stored in mineral crystal lattices. The method revolutionized archaeological dating by enabling scientists to date ceramic vessels and fired clay objects directly, providing absolute chronologies for human occupation sites worldwide. |
