Water heterogeneous radiolysis in the presence of radium silicate

Radium silicates with different radium contents were synthesized. For comparison, the radiation catalytic activity of radium silicate with 6100 Bk/g radium and starting silicate during the radiolytic decomposition of water was studied. The heterogeneous radiolysis of water was investigated in the adsorbed and liquid states in contact with radium silicate and silicate samples. The effect of the radium cations, the state of water, and reaction temperature on the yield of molecular hydrogen was revealed. The mechanisms of heterogeneous radiolysis of water involving the radium silicate and silicate samples under study were suggested.
