A Pedagogical Numerical Simulation of Persistent Luminescence Phenomenon for Teaching Radiation Dosimetry

Abstract

This paper presents the theoretical bases and numerical simulation of the persistent luminescence applied to radiation dosimetry to create an educational exercise for undergraduate students who are beginning in the areas of physics and radiation dosimetry. Numerical simulation of persistent luminescence curves was performed using Mathcad v15 software. Persistent luminescence curves with first-order kinetics were simulated, and their relationship with the thermoluminescence phenomenon was also studied. In addition, this paper explains a series of numerical simulations that include various types of experiments that can be carried out to characterize materials that are constituted by a persistent luminescence property, for instance, dose-response, reusability, selection of measurement temperature, determination of lifetime [Formula: see text], energy activation E, and frequency factor s.
