Dose–Response of TLD-100 in the Dose Range Useful for Hypofractionated Radiotherapy [PDF]

open access: yesDose-Response, 2020
Purpose: The aim of the study was to exploit the feasibility of thermoluminescent dosimeters (TLDs) in radiation therapy techniques in which high dose per fraction is involved. Methods: Dose–response of TLD-100 (LiF: Mg, Ti) was investigated in both 6-MV

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

open access: yesJournal 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.

Evaluation of LiF:Mg,Ti (TLD-100) for Intraoperative Electron Radiation Therapy Quality Assurance. [PDF]

open access: yesPLoS ONE, 2015
Purpose of the present work was to investigate thermoluminescent dosimeters (TLDs) response to intraoperative electron radiation therapy (IOERT) beams. In an IOERT treatment, a large single radiation dose is delivered with a high dose-per-pulse electron ...

The use of LiF (TLD‐100) as an out‐of‐field dosimeter [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2007
The commonly used thermoluminescent dosimeter TLD‐100 (Harshaw Chemical Company, Solon, OH) responds not only to photons and electrons, but also to neutrons that are produced during high‐energy therapies. As a result, TLD‐100 measurements outside of the treatment field are suspect when high‐energy radiation is used.

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

open access: yesSüleyman 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 ...

Investigation of Thermal Quenching Effect for Lithium Fluoride (LiF) Type Dosimeters

open access: yesCumhuriyet Science Journal, 2023
Thermal quenching is described as a decrease in luminescence efficiency with increasing measurement temperature. Luminescence intensity decreases with increasing heating rates in the presence of thermal quenching.
