Thermoluminescence dating accuracy

These crystalline solids are constantly subjected to ionizing radiation from their environment, which causes some energized electrons to become trapped in defects in the molecular crystal structure.An input of energy, such as heat, is required to free these trapped electrons.The 100 simulated natural variants are generated by keeping the transition probabilities between energy levels fixed, while allowing simultaneous random variations of the concentrations of the 11 energy levels.The SAR-OSL protocol was found to be intrinsically both more accurate and more precise than the SAR-ITL protocol.decay or the rate of other cumulative changes in atoms resulting from radioactivity. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number..One half-life is the amount of time required for of the original atoms in a sample to decay.

Heating the material enables the trapped states to interact with phonons, i.e.The simulations are carried out using a recently published comprehensive kinetic model for quartz, consisting of 11 electron and hole traps and centers.
