Abstract

We have studied the luminescent properties of MgO ⋅ 2.5Al2O3 nonstoichiometric spinel irradiated in direct and scattered beams by 12-MeV electrons accelerated in an M-30 microtron. It is established that the kinetics of irradiation-induced phosphorescence decay is described by the Beckuerel hyperbola with an exponent increasing with the electron fluence. The laws of thermoluminescence peak variation in 110—250°C temperature interval were also studied depending on the irradiation dose. It is concluded that the behavior of this peak can be used for clinical and technological diagnostics of pulsed electron beams.
