Investigation of LiF, Mg and Ti (TLD-100) Reproducibility [PDF]

Journal of Biomedical Physics and Engineering, 2015
LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137.

A Photo-transfer Thermoluminescence (PTTL) Study of TLD-100 over a Wide Dose Range

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2023
Photo-transferred thermoluminescence (PTTL) is defined as the transfer of electrons from deep traps into shallow traps via optical stimulation. The importance of PTTL is that it allows for a second measurement of dose assessments for accuracy in cases ...
