Abstract
Abstract Thermal decomposition of γ-treated (0.1–0.5 MGy) ammonium permanganate was studied by IR spectroscopy over the temperature range 25–200°C. Decomposition is shown by a decrease in the MnO4- and NH4 + peak intensities. NO3 formation was observed only in the preirradiated samples and has been attributed to the oxidation of NH3 to HNO3 via HNO radicals. The samples attained additional stability towards gamma radiation when exposed in the pelletized state.
