Thermoluminescent Response of TLD-100 to Low Energy Protons
Radiation Protection Dosimetry, 1999The fluence-response curve of LiF:Mg,Ti (TLD-100) exposed to 0.7, 1.5 and 3 MeV protons has been measured in the 10 7 -10 12 protons.cm -2 fluence range. The total TL signal and glow curve peaks show in all cases a linear-supralinear response and the degree of supralinearity increases with the energy of the incident beam and the temperature of the TL

Photoluminescence and thermoluminescence of Ti centers in LiF (TLD-100)
Journal of Applied Physics, 1984The influence of thermal treatments (quenching and annealing) on the optical absorption and luminescence (emission and excitation) spectra of the Ti-related 200-nm absorption band is studied. Correlations between thermoluminescence (TL) and photoluminescence (PL) emission spectra at different temperatures support the identification of the 200-nm Ti ...

Supralinearity, sensitisation and phototransferred thermoluminescence in LiF TLD-100
Journal of Physics D: Applied Physics, 1982A recently proposed model to explain the supralinearity, sensitisation and PTTL in LiF TLD-100 is discussed in detail. It is shown that the predictions of the model are not borne out by the experimental results, and hence the model in its present form is inadequate.

High ambient temperature effects in LiF TLD-100
Journal of Physics D: Applied Physics, 1991Experimental results for the evolution of the TLD-100 glow peaks IV and V during storage at 70 degrees C are presented. These results confirm a previous conclusion on the null incidence of spontaneous release of radiation-induced trapped charges on this evolution.

On the mobile interstitial model for TL in LiF-TLD 100
Journal of Physics C: Solid State Physics, 1984In recent years, Alvarez Rivas and co-workers (1972, 1974) have proposed a model for thermoluminescence in alkali halides in which the mobile entity is an interstitial, and not a hole or an electron as assumed in the conventional models. Recently, Sagastibelza and Alvarez Raivas (1981) have extended the model to LiF-TLD 100.

Role of peak IV in the sensitisation of LiF TLD-100
Journal of Physics C: Solid State Physics, 1982Peak IV in LiF TLD-100 is different from the rest of the glow peaks (I-V) in that it does not appear in the glow curves of sensitised samples or in photo-transferred TL glow curves. This behaviour is discussed in the light of a recently suggested model for the TL process in this material.

Relative Efficiency Of TLD-100 Exposed to X-Rays
AIP Conference Proceedings, 2008The relative efficiency of TLD‐100 (LiF:Mg,Ti) exposed to X‐rays in the range from 30 to 250 kV, with respect to 60CO gamma rays has been measured. Glow curves were deconvoluted into peaks 3 to 9. All efficiencies were greater than 1 having a maximum of 1.38 for the dosimetric region (peaks 3+4+5) and peaks 4, 5 and 9, and 2.2 for peaks 6a, 6b, 7 and 8

On the hole character of LiF TLD-100 peak IV
Journal of Physics D: Applied Physics, 1992This communication presents new experimental evidence on the intrinsic character of the TLD-100 peak IV trap, which is not created by exposure to ionizing radiation. This intrinsic character, together with the confirmation of the absence of this peak from the UV transferred thermoluminescence glow curve, permits the identification of this peak as being

TLD-100 and Radiochromic Dye Film in Medical Dosimetry
AIP Conference Proceedings, 2006TLD‐100 and radiochromic dye films are two types of the dosimeters most used in the medical physics area. Both are secondary detectors and operate in a different way and in different dose measurement ranges. The use of TLD‐100 is based on the thermoluminescent process, and the RDF in the optical density change when has been exposed to an irradiation ...
