1. A method of removing radioactive cesium, comprising a heating step of heating a waste contaminated with radioactive cesium and a CaO source and/or a MgO source at a temperature of from 1,200 to 1,350°C to volatilize the radioactive cesium in the waste, wherein in the heating step, kinds and blending ratios of the waste, the CaO source, and the MgO source are set so that masses of CaO, MgO ...

Diffusion of sodium chloride, cesium chloride and simulated sea water solutions across and into cement pastes and mortars blended with granulated blast furnace slag has been studied. The temperatures of hydration and diffusion were varied between 23and 6O C. Phase chemistry, depth profiles of chloride, and ion migration measurements across paste membranes were used to follow reaction and ...
