The behaviour of swelling and collapsible soils would be better understood by taking into account available data from distribution of moisture and void ratio in the media. A laboratory computerised gamma-ray tomography (CT) has been applied to measure those variables and their spatial distribution on soil media. CT consists basically of scanning a soil sample with gamma-ray and measuring the attenuation coefficients of the soil. The obtained measurements are used to plot an image of soil properties. Some applications of CT to non saturated soils such as the water and unit weight distribution inside soil sample are shown. (A) For the covering abstract see IRRD 881647.
