AI Article Synopsis
- The study explores the isothermal bleaching process of γ-irradiated borosilicate glass at elevated temperatures using real-time optical microspectroscopy for the first time.
- The research focuses on two specific doses of γ-irradiation (0.83 and 1.99 MGy) of International Simple Glass, a nuclear waste simulant produced by Mo-SCI Corporation.
- It introduces a new method for assessing activation energy during this bleaching process, finding that the Urbach energy decay rates yield similar activation energies of approximately 0.24-0.26 eV for both irradiation doses.
Article Abstract
The isothermal bleaching of γ-irradiated glass was studied at elevated temperatures (280-340 °C) by real-time optical microspectroscopy for the first time. The study was performed on γ-irradiated (0.83 and 1.99 MGy) International Simple Glass (ISG) borosilicate nuclear waste simulant made by Mo-SCI Corporation (Rolla, MO, USA). The current investigation proposes real-time optical transmission methodology for the activation energy assessment of isothermal bleaching of γ-irradiated glass. The method is based on robust quantification of the Urbach energy decay rates and yields similar activation energies for both doses within ∼0.24-0.26 eV.
