Dose Dependence of Mechanoluminescence Properties in MgAl2O4: Dy Phosphor

A reliable dosimetry is fundamental for quality assurance of the processes and irradiation products. All dosimetric systems for high doses have some limitation with regard to their use. Dosimetric system should be easy to use, fast to measure, and of low cost. Good phosphor which shows high luminesc...
