Use of Terbium Doped Phosphate Glasses for High Dose Radiation Dosimetry—Thermoluminescence Characteristics, Dose Response and Optimization of Readout Method

Applied Sciences, 2021
The phosphate glass samples doped with Tb2O3 oxide (general formula: P2O5-Al2O3-Na2O-Tb2O3) were synthesized and studied for usage in high-dose radiation dosimetry (for example, in high-activity nuclear waste disposals).

Thermoluminescence of Kaolinite [PDF]

Radiation Protection Dosimetry, 1999
Natural kaolinite (size < 5 ¿m) shows strong thermoluminescence (TL) which could be linked with water loss (~ 120°C peak) and dehydroxylation changes (~ 300°C peak). After 100 min of dehydration at room temperature, kaolinite displays microcracks, isothermal luminescence emissions and the starting point of a desiccation plateau.
