Photostimulated Luminescence (PSL)

Used in wide range of dosimetric applications.

Photostimulated Luminescence (PSL or POSL)

Green stimulated OSL response of a single Al2O3:C crystal to 100 cycles of the identical beta dose measured in a lexsyg research

Photostimulated Luminescence (PSL or POSL) is also called Optically Simulated Luminescence (OSL) and can be used for a wide range of dosimetric purposes. It is gaining importance in radiation protection dosimetry, personal dosimetry, medical dosimetry and space dosimetry due to the high sensitivity of some phosphors and is a good alternative for film dosimetry.

  • Al2O3:C from a few µGy up to several Gy

  • BeO from a few µGy up to several Gy

  • Na-dosemeters: Na2SiF6:Cu,P

  • Other materials like BaSo4, BaSo4:Eu, …

  • In the form of powder, discs, cubes, …

  • Natural minerals like quartz and feldspar from a few mGy up to several 100 Gy

  • Dating of sediments

  • Higher sensitivity than TL

  • Sensitivity  to light requires extra safety precautions
