Development of magnesium tetraborate as a material for thermoluminescence dosimetry
… is a candidate phosphor for a laser-heated thermoluminescence (TL) dosimetry system which is under development. Near tissue-equivalent radiation absorption properties and reported sensitivity to low radiation doses offer advantages over commonly employed LiF phosphors. Sintered wafers …

Thermoluminescence in Carbonate Rocks and its Application to Stratigraphic correlation and Geologic Age Determination
<p>Thermoluminescence is the temperature dependence of phosphoroscence and is common to most carbonate rocks. Although the phenomenon has been known since at least 1663, its use in geology was not investigated until 1948. </p><p>Thermoluminescence results from the release of energy stored as …

Electron Spin Resonance Spectroscopy: A Potential Technique for Dating Ancient Ceramics
Thermoluminescence dating of archaeological ceramics is a well-established technique. Another instrumental method for measuring the same information (ionizing radiation damage in crystal) is electron spin resonance spectroscopy (ESR), a method which offers the advantages of no temperature dependent …

Optimization of the MgS:Eu:Sm phosphor for potential use as an optically stimulated personnel dosimeter
… lattice. In addition, UV photoluminescence and thermoluminescence of the MgS:Eu:Sm phosphor was investigated to improve the understanding of the optical processes in MgS:Eu:Sm phosphors.

Structure-Composition Relationships and Their Influence on Long Luminescent Lifetimes in Persistent Luminescent Phosphors
… responsible for creating electron traps; yet, thermoluminescence experiments proved a co-dopant was not necessary to observe PersL. This supports the notion that lattice defects are the main electron traps driving PersL. The work presented herein addresses this question using a combination of …

Photoluminescence Properties of Lanthanide doped Wide Gap Compounds of Interest in Photonics
… a function of temperature. Phosphorescence and thermoluminescence properties were also investigated. In particular three main issues of basic research and technological relevance were addressed: the interactions between the rare earth elements and the thiogallate matrix, the interactions between …

Les terres cuites architecturales des églises du haut Moyen Age dans le nord-ouest de la France et le sud-est de l'Angleterre : application de la datation par luminescence à l'archéologie du bâti
… species used in the dating process. Results from thermoluminescence (TL) and optically stimulated luminescence (OSL) dating performed on 53 CBM samples from 12 churches of north-west France and south-east England showed that the practice of reusing Roman brick was commonplace in small parish …

Archaeomagnetic Directional Studies Of Large Fired Structures In Britain
… general consistency with 14c dating but not with thermoluminescence dates. An archaeomagnetic curve of "best fit" incorporating all dating methods largely confirms the previous Iron Age secular variation curve. Field observations, systematic sampling and magnetic measurement of features of various …

Luminescence dating of Scottish burnt mounds: new investigations in Orkney and Shetland
… dose rates of samples collected. Additive dose thermoluminescence dating techniques have been applied to extracted feldspar grains. A procedure for correcting temperature-shift due to thermal contact variation has been developed and implemented, leading to improvements in data processing. …

Evaluation of The Effectiveness of Anisotropic Analytical Algorithm In Flattened and Flattening-Filter-Free Beams For High Energy Lung Dose Delivery Using The Radiological Physics Center Lung Phantom
… with the experimental data as measured using thermoluminescence detectors (TLD) and radiochromic films that were placed inside the phantom. The results demonstrate that the AAA superposition-convolution algorithm is able to calculate SBRT treatment plans with all clinically used photon beams …

Attempts to analyse D/H ratios of sub-micromole quantities of hydrogen : applications in the study of ordinary chondrites
… analytical techniques (chemical/petrographic, thermoluminescence and hydrogen isotope) to study individual fragments of this meteorite. The deuterium-rich phase was found to be concentrated in the chondrules, average δD = +3890‰, with a maximum measured δD of +7500‰ in one of the chondrules. …
