What Does OSTL Stand For?

OSTL stands for Optically Stimulated Thermoluminescence

OSTL, or Optically Stimulated Thermoluminescence, is a luminescence dating technique used to determine the last time mineral grains were exposed to sufficient heat and light. This method involves stimulating trapped electrons within the mineral structure using light, enabling the measurement of stored energy from previous radiation exposure. OSTL is widely utilized in archaeology, geology, and environmental sciences for dating sediments, pottery, and archaeological artifacts, providing valuable insights into past human activities and natural events.
