  abstract = {{W}e have studied the {H}-2 production under ionizing radiation of water confined in synthetic saponite and montmorillonite as a function of the relative humidity. {T}he {H}-2 radiolytic yields in the dry systems are very similar to that measured in a non-swelling clay mineral. {T}hey are 2-3 times higher with one water layer in the interlayer space, evidencing very efficient energy transfers and efficient recombination reactions due to a high confinement. {W}ith two water layers, the {H}-2 yields decrease as compared to the previous case, but remain higher than in bulk water, proving that recombination reactions of hydrogen atoms are less efficient. {E}lectron paramagnetic resonance measurements evidence that reactivity changes significantly with the number of water layers. {S}aponite and montmorillonite give similar results, showing that reactivity is driven by the amount of water and that the details of the clay structure play a less important role. {L}astly, the behavior of natural vs. synthetic swelling clays is discussed. {T}he presence of impurities, even in small quantities, significantly alters energy transfers and has a positive implication for the geological nuclear waste management.},
