Photostimulated Luminescence (PSL)

Used in wide range of dosimetric applications.

Photostimulated Luminescence (PSL or POSL)

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
