Abstract : Samples of particulate soil contaminated with solid particles having higher X-ray absorption coefficients than the soil, are irradiated with a microfocused X-ray beam within an analysis zone to produce X-ray images of such samples. By controlling relative scanning and magnifying movements between the samples within the analysis zone and the X-ray beam, image features corresponding to the solid particles in the soil are rendered detectable for measurement purposes and to provide data from which size and distribution of contaminants in the soil are calculated.
