The mathematical simulation of the radiolysis of aqueous solutions of HClO{sub 4} (0.5-12 mol/l) under X-ray irradiation was performed. An optimal scheme of radiation-chemical reactions was adopted. It was demonstrated that the calculated and experimental yields of ClO{sub 3}{sup -} ions are in good agreement if the yield of ClO{sub 3}{sup -} formation by a direct-action mechanism is taken equal to 3.2 ion/100 eV. By comparing the calculated and experimental yields and the rate curves of ClO{sub 2} and Cl{sup -} formation, the reaction rate constants of HO{sub 2} radicals with ClO{sub 2}{sup -} and ClO{sub 2} radicals with H{sub 2}O{sub 2} were found.
