A thermoluminescent dosimeter, or TLD, is a type of radiation dosimeter, consisting of a piece of a thermoluminescent crystalline material inside a radiolucent package. When a thermoluminescent crystal is exposed to ionizing radiation, it absorbs and traps some of the energy of the radiation in its crystal lattice.

This study consists of a theoretical analysis of the directional planchet heating of Thermoluminescent Dosimeters (TLD) with an emphasis on influence of radiation field type, TL material properties, and heating scheme parameters on the resulting glow curve.

This book is comprised of eleven chapters. The preparation of highly thermoluminescent bismuth doped CaS phosphors, where no pre-irradiation is required for measuring ultraviolet doses is reported. All of the important medical applications of lasers are featured. These phosphors exhibit two TL peaks above room temperature when excited by UV light. The effect of dopant concentration and flux is evaluated for maximising the dosimetric peak.

Thermoluminescent dosimeter. Dr Monica Wong ◈ and Dr Ayush Goel et al. Thermoluminescent dosimeter (TLD) is a passive radiation detection device that is used for personal dose monitoring or to measure patient dose. nickel-coated aluminum card with TLD discs. the discs are made of a thermoluminescent material, commonly calcium sulphate doped with dysprosium (CaSO4:Dy) or lithium fluoride (LiF). nearly tissue equivalent, although not at all x-ray energies 1. the discs are . mm thick and have a . 5 cm diameter.

EL materials have a vast array of applications in the illumination and displays industries, from cheap and energy efficient lighting to large high resolution flat panel displays. The Handbook of Electroluminescent Materials begins with a chapter that outlines the basic physical principles of electroluminescence.

Title: Thermoluminescent material. A phosphor for a thermoluminescent radiation dosimeter, comprises lithium tetraborate as a base material and copper as an activator. In addition to these components lithium octaborate may further be included as a base material, and silver as an activator. The phosphors according to the invention have an effective atomic number quite near to that of tissue, so that it is suitable for measuring the radiation dose absorbed by a tissue specimen.

Thermoluminescent Materials – Types. In general, thermoluminescence is a form of luminescence. The two most common types of thermoluminescent materials used for dosimetry are calcium fluoride and lithium fluoride, with one or more impurities (. It is exhibited by certain crystalline materials, such as calcium fluoride, lithium fluoride, calcium sulfate, lithium borate, calcium borate, potassium bromide, and feldspar. manganese or magnesium) to produce trap states for energetic electrons. The impurity causes traps in the crystalline lattice where, following irradiation, electrons are held.
