dc.descriptionAbstract-A computerized tomograph scanner system using X- and y-rays has been developed for applications in soil science. Previous results were obtained using a miniature X-ray tomograph scanner designed for biomedical analysis [ l]. As a new methodology of instrumentation and in soil research [2], this apparatus has proven to be useful for measuring volumetric water content 8 to an accuracy of *3% and soil bulk density p f 2% (in grams/centimeters3 ). The system features translation and rotation scanning modes, a 200- mm effective field of view, signal processing by pulse counting and 1.0- mm spatial resolution. The performance of the system has been demonstrated by experimentally measuring water content and the bulk density of soil samples.
