Abstract  

Gamma-ray induced decomposition of binary mixtures of potassium nitrate with 90, 70, 50, 30 and 10 mol% SiO2, Al2O3, MnO2, V2O5, La2O3, CeO2, Sm2O3, Eu2O3, Gd2O3 and Dy2O3 has been studied at different doses up to 500 kGy. Radiolytic decomposition of the nitrate is affected by the concentration of the oxide in the binary mixture as well as by the absorbed dose. The enhancement is up to 103 times at 90 mol% of the additive.G(NO2−) values calculated on the basis of electron fraction of the nitrate decrease with the increasing concentration of the nitrate. A comparison ofG(NO2−) for 90 mol% oxides shows decreasing trend as Gd2O3>Sm2O3≈Dy2O3> Eu2O3>CeO2>Al2O3>V2O5>SiO2>MnO2. ESR and TL measurements suggest the formation of radical species which interact with the radical species of nitrate causing enhanced decomposition by energy transfer mechanism.
