Recent Advances in Optically Stimulated Luminescence Dosimetry

The Optically Stimulated Luminescence (OSL) technique has gained acceptance as a personal dosimetry system after the introduction of aluminum oxide (Al2O3) as the dosimetric material. This stems from the fast, very sensitive, and all-optical nature of the measurement technique. These are the same characteristics that make the technique versatile and allow new applications to be developed. This presentation will introduce the OSL and pulsed OSL technique and give a brief overview of some of the applications of OSL currently under development such as fiber dosimetry for radiotherapy and environmental monitoring, and space dosimetry. Special emphasis is given to space dosimetry and recently discovered ionization density dependence properties of the OSL of Al2O3.
