Radiation Protection Dosimetry, 2004
In this paper, the various models dealing with the effects of ionisation density on the thermoluminescence (TL) response (efficiency) of TL LiF dosemeters are discussed. These include (i) the Unified Interaction Model (UNIM), which models photon/electron linear/supralinear dose response; (ii) the Extended Track Interaction Model (ETIM), which models ...

TL Emission Spectra from Differently Doped LiF:Mg Detectors
Radiation Protection Dosimetry, 2002There are two widely applied types of thermoluminescent detectors based on LiF:Mg luminophor: Lif:Mg,Ti and highly sensitive LiF:Mg,Cu,P. The role of luminescence centres in these materials is usually attributed to defects connected with, respectively, titanium and phosphorus dopants. In order to check how composition of dopants introduced into the LiF

Comparison of time effects, decision limit and residual signal in Harshaw LiF:Mg,Ti and LiF:Mg,Cu,P
Radiation Protection Dosimetry, 2006The personal dosimetry service of the UK Health Protection Agency--formerly of the National Radiological Protection Board (NRPB)--is currently commissioning a body thermoluminescence dosemeter (TLD) system based on the use of Harshaw 8800 readers and two-element cards.

Behaviour of LiF:Mg,Cu,P and LiF:Mg,Ti thermoluminescent detectors for electron doses up to 1MGy
Radiation Measurements, 2010Abstract The behaviour of LiF:Mg,Cu,P and LiF:Mg,Ti detectors at ultra-high doses up to 1 MGy, has been investigated. The presence of the ultra-high-temperature peak (450 °C) of reproducible properties was observed in various batches of LiF:Mg,Cu,P, confirming earlier findings. The results indicate that this peak is not an effect of random impurities

Personnel Dosimetry Using LiF:Mg,Cu,P
Radiation Protection Dosimetry, 1999Significant advances have been made in recent years in the development of new and improved thermoluminescent (TL) materials for applications in personnel and environmental dosimetry. One of the most promising new TL materials is LiF:Mg,Cu,P. This paper provides an up-to-date review of the main dosimetric properties of LiF:Mg,Cu,P, emphasising recent ...

Radiation Measurements, 2004
Abstract An environmental radiation monitoring system using standard MTS-N (LiF:Mg, Ti) and high-sensitive thermoluminescent LiF:Mg,Cu,P (MCP-N) detectors was applied to control the radiation exposure over the area of the Institute of Nuclear Physics (INP) in Krakow.

Thermoluminescence and Color Centers in LiF:Mg
Journal of Applied Physics, 1967A variety of optical absorption, emission and luminescence excitation spectra have been measured in an attempt to identify the centers involved in the thermoluminescence of commercial LiF:Mg. It is concluded that the principal trapping centers consist of a hole trapped near various groupings of Mg2+ ions and vacancies.

The Annealing Characteristics of LiF:Mg,Ti
Radiation Protection Dosimetry, 1990New data concerning some of the standard annealing procedures routinely applied to LiF:Mg,Ti, especially the influence of the reproductibility of the annealing temperature profiles on the dosimetric precision, are presented. Based on these investigations, and based on the criterion that the annealing should be carried out at a temperature where the TL ...

Radiation Protection Dosimetry, 1994
Thermoluminescence (TL) dosemeters, placed about 1 m above the ground in selected outdoor sites, provide a simple tool for the measurement of the dose, due to both natural and man-made radiation, in the environment. Since the radiation doses to be monitored are usually low (0.3 to 0.8 mGy per year) the TL chips required for long-term dose measurements ...
