TL/OSL dating has been developed rapidly since it was proposed about 60 years ago. TL dating was mainly applied in fired or heated materials, where the luminescence clock was reset when they were last heated, while OSL dating has been primarily applied to sediments in which the clock was reset to zero when they were last exposed to sunlight. TL/OSL dating has its advantages over other dating methods in both age range and material range, so that it can determine ages that cannot be achieved with other radiometric dating methods. This chapter describes the practical aspects of TL/OSL dating. Commonly used minerals and protocols are described. Dating techniques and methodologies are presented and outlined, and developments in recent years are discussed.
