Response of TLD‐100 in mixed fields of photons and electrons
Medical Physics, 2013Purpose:Thermoluminescent dosimeters (TLDs) are routinely used for dosimetric measurements of high energy photon and electron fields. However, TLD response in combined fields of photon and electron beam qualities has not been characterized. This work investigates the response of TLD‐100 (LiF:Mg,Ti) to sequential irradiation by high‐energy photon and ...

On the order of kinetics for thermoluminescence in LiF (TLD-100)
Journal of Physics D: Applied Physics, 1983Studies of TL glow curves on powder and single crystals of TLD-100 give essential the same results. Differences in materials are not the source of the discrepancy between the authors' results and those of Kathuria and Sunta (1982). In the authors' results, from isothermal annealing of the TL, they find no evidence for non-first-order kinetics and ...

On the mechanism of phototransfer thermoluminescence in LiF TLD-100
Journal of Physics D: Applied Physics, 1988LiF TLD-100 exposed to 25.8 C kg-1 and then annealed at 350 degrees C for 15 minutes contains defects responsible for the 225 nm optical absorption band and peak XII. Other defects have not been identified in this sample. Consequently, phototransfer thermoluminescence (PTTL) has been assumed to originate from peak XII.

Thermoluminescence of LiF TLD-100 dosimeter crystals
IEEE Transactions on Nuclear Science, 1974The unusually complex thermoluminescence obtained from Harshaw dosimeter type TLD-100 LiF crystals has been studied with apparatus for measuring emission intensity simultaneously as a function of both wavelength and sample temperature. A separate signal averaged spectrum is obtained at 5.5 C temperature intervals.

On the trapping centres in LiF TLD-100
Solid State Communications, 1980Abstract Most of the TL in TLD-100 originates from the defects responsible for the optical absorption bands at 310 and 380 nm. Different models have been suggested for these defects and TL mechanism in TDL-100.

On the peculiarities of peak 4 in LiF TLD-100
Radiation Measurements, 1994Abstract A detailed study of the different glow curves that can be obtained from LiF TLD-100 is presented. This study has been made measuring glow curves after different preparation and readout conditions, and using computerized glow curve analysis to resolve individual glow peaks.

Order of kinetics for thermoluminescence in LiF TLD-100
Journal of Physics D: Applied Physics, 1981Comments on the result given by Kathuria and Sunta (ibid., vol.12, p.1573, 1979) for the order of kinetics of peak V of the TLD-100 thermoluminescence. Further results are presented to support the view that peak V has constant first-order kinetics.

Thermoluminescence of LiF TLD-100: Glow-curve kinetics
Journal of Applied Physics, 1978The thermoluminescence kinetics have been determined for the 13 glow peaks contained in the glow curves obtained from LiF TLD-100 after exposure to 60Co irradiations. The glow curves were constructed from measurements made with recently developed equipment for recording emission spectra at closely spaced temperature intervals. In addition, the recorded

Effect of deep traps on the sensitization in LiF (TLD-100) phosphor
Physica Status Solidi (a), 1980The effect of residual thermoluminescence (RTL) on sensitization (S/S0) of peak 5 (197°C) and peak 7 (257°C) in LiF (TLD-100) is studied. Intense UV irradiation (253.7 nm) at a temperature of 300°C is found to completely remove the RTL peak 8 (321°C) and RTL peak 10 (415°C) without altering very much the sensitization of peak 5.

The emission spectrum of LiF (TLD-100) at low and high exposures
Physics in Medicine & Biology, 1972The emission spectrum of LiF (TLD-100) was studied for high and low exposures. The ratio of the thermoluminescence of the high exposure (3.4*104 R) to that of the low exposure (100 R) was the same for all wavelengths. A tendency for the emission spectrum to shift to shorter wavelengths with higher temperature glow peaks was observed.
