ジオポリマーは、種々の含水量およびゼオライト充填量(0-40重量%)で合成した。ゼオライトA,ジオポリマーおよびそれらの複合体を$$^{60}$$Co線源(1.5-2.5kGy/h)で10kGyまで照射した。照射後に水素量をGCで測定し、放射線分解による水素収量を求めた。収量の値から、照射中の水素再結合反応が示唆された。観測された挙動を理解するために実験系をモデル化し、より大きな試料の照射で発生する水素量を試算した。

Geopolymers were successfully synthesized with different water content and loading of zeolites (0 to 40%wt). Zeolite A, geopolymer and their composites were then irradiated by a $$^{60}$$Co source (1.5 to 2.5 kGy/h) up to 10 kGy. The hydrogen was measured by GC after irradiation. Yields of radiolitic hydrogen were obtained for individual components. Obtained yields suggested a recombination process during irradiation. The system was then modelled to explain the observed behavior and predict the hydrogen production under $$gamma$$ ray irradiation of larger samples.
