Hydrogen production in α-irradiated bentonite

The hydrogen production in α-irradiated (dose rate 0.73 Gy·s−1), compacted, water-saturated bentonite (ρ=2.12 g·cm−3) has been determined experimentally, using a gas-chromatographic technique. Hydrogen concentration in the clay pore water and hydrogen diffusion out of the irradiated bentonite have been calculated using a homogeneous reaction model. The calculated hydrogen transport out of the bentonite depends on the Fe2+ and HCO 3 concentration in the pore water. Agreement between experimental and calculated results can be obtained if it is assumed that a 20 μm layer of water is formed between, the clay and the α-source.
