RADIATION DOSIMETRY: FROM THERMOLUMINESCENCE DOSIMETER ##(TLD) TO OPTICALLY STIMULATED LUMINESCENCE DOSIMETER ##(OSLD).
Pak J Radiol Jan ;21(3):107-9.

In medicine, radiation dosimetry is an important and regulatory requirement for surveillance of radiation workers in radiology, nuclear medicine and radiation oncology. It is also required for quality assurance (i.e. precise estimation of delivered dose to patient) in external beam radiation therapy and brachytherapy as well. In this review we will discuss types of dosimeters used in medical physics, principles of luminescence, comparison of thermoluminescent detectors (TLD) and optically stimulated luminescence (OSL).
