Abstract
The lifetimes of infrared stimulated luminescence (IRSL) signals have been determined with a method involving a pulse annealing experiment. At an ambient temperature of 10 °C, lifetimes of 1.0 x 10 9 and 0.9 x 10 4 y were obtained for potassium and sodium feldspar separated from a sediment, respectively. Implications for IRSL dating limits are discussed.
