一些硫酸盐基质中 KNO3 的伽马射线分解，即。 Na2SO4、K2SO4、KNaSO4、KNaSO4: Eu、KNaSO4: Ce、K3Na(SO4)2、K3Na(SO4)2: Eu 和 K3Na(SO4)2: Ce 在吸收剂量为 30 kGy 时进行了研究。根据所有硫酸盐中的电子分数计算的 G(NO2–) 值均显着增强。它还受到外部阳离子和掺杂剂镧系元素的性质的影响。电子自旋共振 (ESR) 和热释光 (TL) 测量显示在伽马射线照射下自由基物种 SO4–、SO3–、O3–、O2– 的形成。据推测，这些自由基物质可以传递能量并与硝酸盐自由基物质（NO32-、NO2、NO3等）相互作用，从而促进分解。已经提出了一种可能的机制。
Gamma-radiolysis of KNO3in the matrix of some sulfates, viz. Na2SO4, K2SO4, KNaSO4, KNaSO4: Eu, KNaSO4: Ce, K3Na(SO4)2, K3Na(SO4)2: Eu and K3Na(SO4)2: Ce has been studied at an absorbed dose of 30 kGy.G(NO2–) values calculated on the basis of electron fraction in all the sulfates are enhanced significantly. It is also affected by the nature of outer cation and the dopant lanthanide. Electron spin resonance (ESR) and thermoluminescence (TL) measurements show the formation of radical species SO4–, SO3–, O3–, O2–upon gamma -irradiation. It is proposed that there radical species may transfer energy and interact with the radical species of nitrate (NO32–, NO2, NO3etc.) so as to enhance the decomposition. A possible mechanism has been proposed.
