The amount, rate of formation and radiation-chemical yields of molecular hydrogen obtained from the process of radiolysis under the influence of gamma quanta (60Co, P=9.276 rad/s, T=300 K) in the nano-SiO2/H2O system with a mass of particle of m=0.2 g and size of silicon particle of d=20÷60 nm by changing of water mass (m=0.01÷0.8 g) were studied. It was found that the rate of formation and radiationchemical yield of molecular hydrogen determined by increasing the mass of water • decrease by 10 times for water, • increase by 8 times for nano-silicon dioxide, • for common system, increase at the values of water mass of 0.01 gm H2O 0.2 g, have the maximum at mH2O =0.2 g and decrease at 0.2 g< mH2O 0.8 g.
