What does OSL stand for?

Explanation:
In this topic, OSL refers to how light can release stored energy in a luminescent material to indicate radiation dose. The acronym stands for Optically Stimulated Luminescence. In practice, ionizing radiation creates trapped electrons in a crystal. When you illuminate the material with light (often blue), those trapped charges are released and recombine, producing luminescent photons. The intensity of that light is proportional to the absorbed dose, so you can read out how much radiation the material has encountered. This approach differs from thermoluminescence, which uses heat to release the stored energy. Materials like aluminum oxide doped with carbon (Al2O3:C) are common OSL dosimeters, read with a light-stimulated signal detected by a sensor.
