The amount of hydrogen produced in -radiolysis of mixture of seawater and mordenite was studied. The measured yield was decreased with decrease in the weight fraction of seawater. However, the yield was not simply proportional to the weight fraction of seawater and the influence of the mordenite was observed as additional production of hydrogen. At a weight fraction of seawater more than 0.2, the measured amount of hydrogen could be explained by an empirical equation given by a liner combination of two hydrogen production terms representing hydrogen production due to the energy deposition to seawater and that to mordenite. Each of the terms was expressed as a product of the absorbed energy and a yield given as the proportionality coefficient, and each of the yields could be a constant independent of the mixture ratio. The result imply an instinctive explanation of hydrogen production from the mixture of solid and liquid using the two respective yields.
