Effects of gamma-radiation on Bentonite project funded by SSM

The Swedish Radiation Safety Authority, or SSM in short, are funding a 1-year project in the Holmboe group!

In the context of nuclear waste disposal in Sweden and many other countries, this project will investigate the effects of redox and physicochemical changes induced by gamma (γ) irradiation on compacted Bentonite clay and its main component montmorillonite. This is relevant since in nuclear waste repository concepts such as the Swedish KBS-3, the compacted and water saturated Bentonite clay buffer will unavoidably be exposed to significant doses (40-200kGy) of ionizing 137-Cs radiation, which may induce redox-changes in the structural Fe(II)/Fe(III) sites in the clay mineral lattice.
