A laboratory method to measure gas diffusion and flow in soil and other porous materials

, : A laboratory method to measure gas diffusion and flow in soil and other porous materials. Journal of Soil Science 32(3): 323-333

An apparatus was constructed to measure diffusivity of krypton-85 and gas permeability in an enclosed core of soil of field structure or in other porous material. Sample enclosure decreased water loss by evaporation, reduced mass flow caused by changes in ambient temperature and pressure during diffusion measurement, and allowed subsequent measurement of gas permeability without further sample disturbance.
