This document describes rules for the procedures, applications, and systems of thermoluminescence 
dosimetry (TLD) for dose measurements according to the probe method. It is particularly applicable to 
solid “TL detectors”, i.e. rods, chips, and microcubes, made from LiF: Mg ,Ti or LiF: Mg ,Cu ,P in crystalline 
or polycrystalline form. It is not applicable to LiF powders because their use requires special 
procedures. The probe method encompasses the arrangement, particularly in a water phantom or in a 
tissue-equivalent phantom, of single TL detectors or of “TL probes”, i.e. sets of TL detectors arranged in 
thin-walled polymethyl methacrylate (PMMA) casings.
The purpose of these rules is to guarantee the reliability and the accuracy indispensable in clinical 
dosimetry when applied on or in the patient or phantom. This document applies to dosimetry in 
teletherapy with both photon radiation from 20 keV to 50 MeV and electron radiation from 4 MeV 
to 25 MeV, as well as in brachytherapy with photon-emitting radionuclides. These applications are 
complementary to the use of ionization chambers.
