Energy dependence of TLD 100 and MCP-N detectors

Radiation Measurements, 2008
Abstract One of the most important characteristics of thermoluminescent detectors, if they are intended to be used in a wide range of energies, is their energy response. Thermoluminescent detectors (TLD) 100H and MCP-N, which are the commercial names of the LiF:Mg,Cu,P material, are being examined for their energy response against the well known and ...

TLD-100 and Radiochromic Dye Film in Medical Dosimetry

AIP Conference Proceedings, 2006
TLD‐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 ...

Fractional order of kinetics in LiF-TLD 100

Journal of Physics D: Applied Physics, 1984
In a recent letter, McKeever and Lilley (1983) have argued that the non-first-order kinetics for LiF-TLD 100 obtained by Kathuria and Sunta (1983) is an artefact of their experimental set-up. In this letter it is shown that this is not the case.

Thermal quenching by phototransfer in LiF TLD-100

Physics in Medicine & Biology, 1981
Describes an application of the phototransfer property of LiF TLD-100 in the quantitative estimation of a factor for thermal quenching for the high temperature glow peak (385 degrees C) relative to the TL in the temperature region 25-300 degrees C.

Mixed radiation dosimetry with LiF (TLD-100)

Physics in Medicine & Biology, 1970
The LiF dosemeter presents two main glow peaks, one at 210 degrees C and the other at a temperature between 250 and 300 degrees C. It is shown that the two-peak ratio depends on the type of incident radiation. This characteristic makes it possible to use LiF to measure doses in mixed fields (slow neutrons and electromagnetic radiations).

Thermoluminescence of LiF TLD-100 by phototransfer

Journal of Physics D: Applied Physics, 1976
The residual trapped charge carriers remaining after incomplete annealing of an irradiated thermoluminescent (TL) sample can be transferred to empty trapping sites by incident ultraviolet (UB) photons. Phototransferred thermoluminescence (PTTL) in LiF TLD-100 was studied as a function of the residual glow curve intensity the photon energy of the ...

Order of kinetics for thermoluminescence in LiF (TLD-100)

Journal of Physics D: Applied Physics, 1982
Results are presented on the decay of glow peak V (190 degrees C) in powder as well as single crystal chip samples of LiF. The absence of peak IV (170 degrees C) is confirmed and any contribution from higher temperature glow peaks is accounted for, to ascertain that the decay represents the uncontaminated peak V.

Response of TLD‐100 in mixed fields of photons and electrons

Medical Physics, 2013
Purpose: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 ...
