Thermoluminescence response of Ge-doped SiO2 fibres to electrons, X- and γ-radiation
TL;DR: In this article, the authors investigate the thermoluminescence (TL) response of tailor-made Ge-doped SiO2 fibres for accelerated electrons (6, 12 and 20 MeV), megavoltage X-rays (6 and 10 MV) and 1.25 MeV γ-rays, delivered by a linear accelerator (LINAC) and a Co-60 irradiator respectively.

Commercial optical fibre as TLD material
TL;DR: The SiO2 commercial optical fibre studied demonstrates useful TL properties and is an excellent candidate for use in TL dosimetry of ionising radiation and can be re-used several times, after thermal annealing, without any detriment in the dose-response.

Low Pre- and Post-Irradiation Fading of LiF:Mg, Ti (TLD-100, TLD-600, TLD-700) Using a Preheat Technique
TL;DR: An attempt was made at the Soreq Dosimetry Centre to reduce the fading following or preceding gamma radiation, by employing a high post-irradiation preheat temperature of 150°C, lending support to the claim that the technique of high preheatTemperature reduces the fading of LiF:Mg,Ti TL signal.
