Abstract
The present invention discloses one or more compounds that oscillate between a first state and a second state due to absorption of high energy, with the oscillations facilitating prevention of solarization of a glass system for reuse while generating scintillations for determining existence of high radiation energy. The generation of scintillations have a duration that is commensurate with a duration of the irradiation of the glass system, and cease when irradiation is ceased without affecting the glass system.
