摘要

Numerous naturally occurring mineralsMineral serve as thermoluminescent dosimeter (TLDThermoluminescent dosimeter (TLD)) materialsMaterials. The thermoluminescenceThermoluminescence (TLThermoluminescence phenomena (TL)) characteristicsCharacteristics of these mineralsMineral are influenced by the specific type and concentration of trace elementElement impuritiesImpurities they contain. MineralMineral formation and impurityImpurities concentration are both influenced by mineral'sMineral geological and geographical origin. Silicate mineralsSilicate minerals, including quartzQuartz and feldsparFeldspar, along with certain oxideOxides mineralsMineral like aluminum oxidesAluminum oxides, distinctly exhibit TL peaksTL peaks in glow curvesGlow curve resulting from trapsTrap formed through thermal treatmentThermal treatment and irradiationIrradiation. QuartzQuartz (SiO2), a particularly abundant silicate mineralSilicate minerals in the Earth's crust, forms under various geological conditionsGeological conditions, including magmaticMagmatic, hydrothermalHydrothermal, sedimentarySedimentary, and metamorphicMetamorphic processes. It plays a crucial role as a rock-forming mineralMineral across all rock typesRock types (igneous, sedimentarySedimentary, and metamorphicMetamorphic). Natural quartzNatural quartz, one of the dosimeters utilized in luminescenceLuminescence investigations, is significantly important for assessing the radiation record of materialsMaterials in a wide range of applicationsApplications including evaluating the authenticity of artifacts or retrospective dosimetry (nuclear accident). This chapter discusses TLThermoluminescence phenomena (TL) phenomena and types of luminescenceLuminescence. The kineticKinetics modelsModel which describe the TLThermoluminescence phenomena (TL) phenomena were included. Different methods used to analyze TL glow curvesTL Glow Curve and extracting the kinetic parametersKinetic parameters were deliberated. The physical propertiesPhysical properties and the applicationApplications of quartzQuartz were declared in this chapter. Thermoluminescence phenomenaThermoluminescence phenomena (TL) and Dosimetric parametersParameter of QuartzQuartz collected from various places were shown clearly.
