Abstract
The salts Na2S2O6, Na2S2O6•2H2O, K2S2O6, BaS2O6, and BaS2O6•2H2O were irradiated at room temperature with 60Co gamma rays. When the irradiated salts were dissolved in water sulfite ions, sulfate ions, and acid were found as irradiation products. The dependence of yield upon absorbed dose was studied. The G-values found ranged from unity to 20. Thermal annealing of the irradiated salts had only a slight effect on product yields. For BaS2O6 there is a large increase in product yields after a dose of 28.3 × 1022 eV per mol has been absorbed. A mechanism involving SO3− and S2O6− radical ions is proposed.Keywords
