Detection material for thermoluminescent dosage element, dosage element and preparation method and application thereof

The invention discloses a detection material for a thermoluminescence dosage element, the dosage element and a preparation method and application of the dosage element, and relates to the technical field of personal accumulated radiation dosage detection. According to the invention, sodium chloride is taken as a main body, calcium chloride is taken as a dopant, the particle size of powder and the doping amount of Ca < 2 + > ions are strictly controlled, the sodium chloride and the calcium chloride are mixed and ground, and then compression molding and solid-phase sintering are carried out to directly prepare the dosage sheet as a thermoluminescent dosage element. The preparation process adopted by the invention has the characteristic of simple and short procedures, is convenient for streamlined operation, is relatively low in cost of used equipment and materials, does not generate waste liquid and waste gas in the preparation process, and is more suitable for large-scale production and application. The thermo
